A Set of Elastic Bands W/ Adequate Resistance Can Fully Replace the Gym When You're Travelling - True or False?!

If you're doing only single-joint aka isolation exercises, you could fully replace your gym with a complete set of resistance training bands.
Wouldn't it be nice if all you had to do to be able to continuously make progress in the gym while you're traveling without even having to go there... I mean, to a gym? That's obviously a rhetorical question - a question the results of a recent study from the Norges Teknisk-Nnaturvitenskapelige Universitet in Trondheim, Norway (Iversen 2017), suggests that it can be answered in the affirmative... almost, at least, if you pack one or multiple (in that case with various resistances), elastic bands, whenever you travel.

Ah, and no... before you ask, the disclosure statement says the authors have "no potential conflict of interest".

Bands can Make Deadlifts More Effective

Chains and Bands Will Boost 1RM Gains

Bands Diversify and Improve 'ur Workouts

Full ROM ➯ Full Gains - Form Counts!

BFR-Preconditio- ning Useless for Weights?

Study Indicates Cut the Volume Make the Gains!
The fact that they used TheraBands® in the ERB (elastic resistance bands) group is thus probably a means to make the results representative of the results the largest group of resistance trainees would see. Speaking of groups, to elucidate, whether elastic resistance bands (ERB) can be a viable option to conventional resistance-training equipment (CRE) during multi-joint resistance exercises (for single-joint exercises this has already been proven), the authors compared muscular activation levels in four popular multiple-joint exercises performed with
  • ERB (TheraBand®) vs. 
  • CRE (Olympic barbell or cable pulley machines). 
In a cross-over design, men and women (n = 29) performed squats, stiff-legged deadlifts, unilateral rows and lateral pulldown using both modalities.
Figure 1: Overview of the EMG activity of training with resistance band (REB) vs. barbell & machines (CER) - The muscle activity is sign. reduced only during squats (Iversen 2017).
The scientists multilevel mixed-effects linear regression analyses of main and interaction effects, and subsequent post hoc analyses were used to assess differences between the two resistance-training modalities showed that...
  • when all is said and done, the gym is still superior: CRE induced higher levels of muscle activation in the prime movers during all exercises (p < .001 for all comparisons), compared to muscle activation levels induced by ERB.
  • on a per exercise basis, it's yet just the squat, where the muscle activation suffers significantly: the magnitude of the differences was marginal in lateral pulldown and unilateral rows and for the erector spinae during stiff-legged deadlifts; in squats, however, the quadriceps femoris activations were substantially lower for ERB.
The authors also found that the differences between ERB and CRE were mostly observed during the parts of the contractions where the bands were relatively slack, whilst the differences were largely eliminated when the bands became elongated in the end ranges of the movements.
Used correctly - REBs can augment your strength gains in the gym, too.
So what's the verdict? True or false!? Well, the scientists' conclusion that "ERB can be a feasible training modality for lateral pulldowns, unilateral rows and to some extent stiff-legged deadlifts, but not for the squat exercise" says it all. It depends on which body part you're training. The band may not be ideal for squats and thus leg training, but you can replace your gym with something as simple as a set of resistance bands, ... at least in the short run (a study confirming identical gains is still warranted, though, because EMG ≠ gainz, but the 'novelty effect', alone, should help you maintain or even gain muscle over those 1-2 weeks).

What? Oh yes, your guns... well, you must have overread that in the body of the article: Aboodarda, et al (2011, 2013 & 2016), Andersen et al. (2010), Brandt et al. (2013), or Jacobson (2012 & 2014) are only six out of many studies showing increases in strength and/or size with ERB training for single-joint exercises as you'd do them for your biceps and triceps - so there's reason to be afraid of losing your guns | Comment on Facebook!

Halloween Science - A Short List of Important and Trivial Halloween Figures, Fallacies and Horrific Facts

You better watch your treat-intake, if you want to wear this "costume" another year ;-)
I know you probably expected "healthy Halloween recipes" in this special, but you know that this is not exactly my area of expertise.

Ok, ok... Honestly, Halloween per se is not exactly my specialty either. Despite the desperate efforts of the industry to import your not so holy holiday festivities to Germany, the whole idea of dressing up like monsters, vampires, zombies and skeletons to avoid being recognized when you get drunk and laid is something we do in February, in the carneval season, not the night before All Hallow's day.

In view of the fact that the majority of you are from the US or the UK and thus probably just trying to squeeze their astral bodies into last year's Halloween costume, I thought it may still be worth to compile a couple of more or less random pieces of "Halloween research". So, here you go:
  • A Playstation is as welcome as a bag of sweets: I am not sure if that's a real improvement (and it certainly is not surprising), but Schwartz et al. suggest that "nutrition professionals should encourage adults to create holiday traditions that do not rely on unhealthful foods" (Schwartz. 2003) . I guess, though, a football or skates or whatever "pro-kinetic" toy would probably actually qualify as a healthy alternative to the junkfood. But let's be honest: Would you have needed a study to know that "children will not be disappointed by toy treats on Halloween" (Schwartz. 2003)?
  • Random Halloween stats (data from statista.com): With 65.8% the majority of US citizens is going to celebrate today (question was posed in September 2013) - more women than men, by the way (67.1% vs. 64.3%). 
    • Figure 1: How will you celebrate Halloween this year? (September 2013, by gender)
      The $75.03 budged every US citizen is about to spend this year is probably going to be slightly smaller than 2012, where the average spending was still $79.82. The estimated total spending on Halloween festivities for 2013 is ~7 billion US dollars - not bad, but more than 1 billion less than last year. Still, 75% of the respondends of a survey from September 2013 said the economy would not have any influence on the amount of money they planned to spend.
    • Among the adults, participating in the festivities is a prerogative of the younger ones. More than 82% of the US citizens in the group of 18-24 and 25-34 year olds is going to party tonight. In the 50+ age group more than half of the adults are halloween refusineks.
  • Pumpkin & pumpkin seeds - the healthy oddment of the halloween festivities: I know you have been waiting for this, so here they are - the established health benefits of pumpkin, pumpkin seeds and extracts (P & PE)
    • Figure 2:They are best known for prostate protection but a high pumpkin intake protects against gastric and lung cancer, as well - note: the breast and colorectal cancer protective effects, on the other hand, were non-significant (Huang. 2004)
      anti-diabetic - P & PE protect the pancreas against hyperglycemia (Zhang. 2013), lowers blood sugar, inihit b-glucosidase alpha-amylase to inhibit carbohydrate digestion (Yadav. 2012)
    • anti-oxidant - P & PE are a significant source of natural forms of vitamin E, increase hepatic
      activities of superoxide dismutase and glutathione peroxidase in mice, reduce the concentration of malonaldehyde (Yadav. 2012),  protect sperm against oxidative assaults (Aghaei. 2013)
    • anti-carcinogenic - P & PE protect against androgen induced prostate growth (Gossell-Williams. 2006; Tsai. 2006), have proven anti-cancer effects for other types of cancer, as well (see data from Huang. 2004 in Figure 2)
    • Figure 3: Important bioactive compounds from pumpkin and their biological activities (Yadav. 2012).
      anti-microbial - P & PE kill or inhibit the proliferation of about every bug you know, Acinetobacter baumanii, Aeromonas veroniibiogroup sobria, Candida albicans, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella enterica subsp. enterica serotype typhimurium, Serratia marcescens and Staphylococcus aureus (essential oil; Hammer. 1999)
    • incontinence - PE reduce bladder pressure in rabbit model (works only with oil preparations (!); Zhang. 1994), but reliable evidence from human trials is lacking despite the fact that you can and million people actually do buy corresponding supplements at every pharmacy
    • good source of potassium - P have a high potassium content (300mg/100g; seeds contain more than 1,000mg per 100g; Lazos. 1986), certainly something to remember in view of the low potassium content of the Standard Western Diet (SAD)
  • Halloween is "more fertile" than Valentine's day: It may sound as if this was related to "financial fertility", but it isn't a 2011 Yales study (Levy. 2011) found that the number of children that are born in the "Halloween window" is 8% (=133,087) higher than during the Valentine's-Day window.
    Still, compared to non-holidays the number of spontaneous births was 5.3% and the number of cesareans even -16.9% lower on Halloween. Reason enough for the scientists to come up with a conspiracy theory: "Our findings raise the possibility that pregnant women may be able to control the timing of spontaneous births" (Levy. 2011) - it that's not far fetched, it's imho at least pretty irrelevant, don't you think so?
Rollmops is an obligatory part of the German version of "Tom's breakfast"
About to get drunk? Maybe this brief history of anti-hangover cures can help you avoid the worst side effects. The ancient Assyrians swore by Ground birds' beaks and myrrh. Raw eel and bitter almonds is a recipe from Europe that was popular during the Middle Ages. The Mongolians were more into sheeps' eyes, while the Chinese went with green tea. Us Germans like it traditional (not me though) and eat "Tom's breakfast" (KaterfrĂĽhstĂĽck), a postbinge breakfast with Bismark Herring, pickles, rollmops (see image to the left) and/or sauerkraut (this stuff does work, by the way, 'cause it helps replenish the lost electrolytes).
  • Your alcohol consumption last year was lower than you think - If you are like the majority of students, Patrick & Lee questioned in their 2010 study you overestimate the amount of alcohol you've been consuming on Halloween significantly. If you still need a hangover cure, I'd suggest you take a another look at what people from all the world do, whenever they have had a drop too much.
  • Drunken or not you better watch out your kids are run over by car - It's a very sad statistic, but according to CDC data from the late 1990 10% of the yearly deaths among pedestrians aged 5-14 years occurs on October, 31 - in the hours between 4pm and 10pm. 
  • "Halloween diarrhea" is a term by which Breitenbach refers in a 1992 paper to the sorbitol induced diarrhea that strikes some patients with a surprising regularity (Breitenbach. 1992 ;-)
Learn from scrapies how you can identify a real zombie tonight (image from Nasiruddin. 2013); learn from the CDC how to "promote awareness" w/ zombie comics.
Boring? Not exciting? What did you expect? Zombie science? Well, I guess I have some pretty crazy infection / vaccine related zombie science for you.

Actually it's rather an idea than solid data though - an idea Melissa Nasiruddin, Monique Halabi, Alexander Dao, Kyle Chen, and Brandon Brown developed in a recent paper (Nasiruddin. 2013) and that revolves around the use of zombies to "raise the awareness", some people may even say "promote" the risk of infectious diseases... sounds hilarious and like the stupid idea of a couple of grad students? If you believe that, I'd suggest you check out the CDC's attempt to exploit this idea before you head off into this unholy night ;-)

"Mini-Fast With Exercise" a la Intermittent Fasting Can Help Minimize the "Damage" During the Holiday Season

I wonder if it is coincidence that the modern Santa is an obese advertisement character invented by some marketing genius working for Coca Cola?
Those of you who have been reading the intermittent thoughts on intermittent fasting (click here and start with the links at the bottom, if you haven't) will remember that the actual number of studies on intermittent fasting, as it is interpreted by most people on the Internet is actually quite scarce. Aside from the Ramadan studies, you mostly see very long fasting periods or other oddities that decrease the significance of the studies. That said, I did hit onto an older study that has been published in Medical Hypothesis in 2009, already. A study with a daily 12-14h "mini-fast" + low intensity aerobic exercise 5x a week and a study the results of which point to the usefulness and practical value of skipping a meal - especially in a time where you give in to nutritional temptations way too easily, anyhow - the holiday season!

Fast, walk, eat and stay lean during the holiday season and afterwards

Especially for those of you who are having some weight issues anyway, the profound body fat loss, the subjects in the Bahadori study which was based on a 7 step program comprising
    * Better than monitoring total fat and GI would be to monitor your N-6 intake, emphasize mono-saturated fatty acids and eyeball the total glycemic load (the latter means potatoes are ok, but cookies are a "better stick to one" item ;-)
  • a mini-fast with exercise (12–14 h) fast during every 24 h + prolonged, moderate-intensity aerobic exercise (e.g. 40-45 minutes of brisk walking) Meals are not
  • no caloric restrictions, but a focus on low fat, low GI meals*
  • an increased consumption in calorie-free beverages during the fast
I know that sounds stupid and 100% mainstream, but if you take a look at the data in figure 1 you will notice that it worked like a charm... well, at least for the 10 overweight men and 17 women who followed this protocol for 12 months.
Figure 1: Body weight and composition, waist and insulin levels from the beginning to the end of the 12 week non-calorically restricted 10-14 hour fast with light aerobic exercise; the asterisk (*) behind body fat (%) and insulin signifies that these values are plotted on the 2nd-ary axes (Bahadori. 2009).
Personally, I believe that one, if not the reason that this protocol worked so well were it's feasibility and flexibility, as well as being allowed to eat to satiety, when the subjects were not fasting. The 27 subjects who participated in the study were also free to chose whether they wanted to skip breakfast or dinner and switch from one to the other strategy on a daily basis to adapt their diet to their working hours and other obligations:
Coffee and teas like green, black oolong and pu-erh are your friends not just during the mini-fasts (read more).
"If participants choose to exercise in the morning, they skip breakfast and do not eat until noon. If they choose to exercise at noon, they skip lunch. If they choose to exercise in the evening, they eat an early light dinner, and then wait at least two hours to exercise (so that fasting insulin levels are restored); no food is consumed between the exercise and bedtime. (A variant of this latter strategy is to eat no dinner at all; several volunteers in the study described below adopted this approach on their own initiative.) To optimize the flexibility of this regimen, participants are allowed to switch the time of their exercise session from day to day." (Bahadori. 2009)
For your personal Christmas fast this could mean you skip breakfast tomorrow (which should not be a problem with the large Christmas dinner in your tummy), go out for a long brisk walk, have a light dinner, like a mixed salad with some cheese and chicken breast, and thus prepare yourself for the next family feast on Christmas day. If you are brunching on the day after Christmas, not a problem, you just sleep out, go for light 30min jog, shower and head over to the brunch. Eat as much as you like, and either skip dinner later or breakfast the day after.

If you are not into coffee and tea, ginger ale is another fasting friendly weight loss drink (read more).
Bottom line: To keep the damage at bay this the "mini-feast + exercise" protocol is probably feasible for anyone. It's easy, it will allow you to take part in all the Christmas festivities and won't have you sit there like an orthorexic leopard who cannot change his spots .

Whether this is a strategy worth following for longer depends on where you are at and where you want to go. If you want to look like a fitness model, it's unlikely to be sufficient to reach your goal. You will, for example, have to tweak that regimen to (a) incorporate strength training or add it in later in the day, (b) think about using a couple of supplements, such as BCAAs, caffeine and green tea during the fast and (c) eyeball the quality of the foods you eat with convenience, fast and junk-food being the exceptions to the rule of eating self-prepared whole food meals.

There are however certain downsides to protocols like this, a potential increase in adipogenesis (22% vs. 12% fat gain) and decreased lean gains (50% vs. 72%), as they were observed in a rodent study by Verbaeyes et al. (see "Eating by The Clock Could Make You Fat") with unrestricted caloric intake within the 6h feeding window, would be an example and evidence that whenever you are effectively trying to gain weight you are probably better off spreading your food intake more evenly across the day. Alternatively, you can enlarge the feeding window to 10h to maximize lean gains without the negative side effects of force-feeding yourself with 2x1,500kcal meals only twice a day or grazing continuously for 6h to meet your caloric demands.

But hey, Christmas is almost there, and there is still enough time to think about dieting and bulking after the festivities. On that note, I wish all of you a happy Christmas, a nice time with your families, friends! Regardless if you fast or not ;-)

Adelfo Cerame: Contest Prep Update on Turkey Day! Plus: Losing Fat W/ Intermittent Fasting & 200g Carbs/Day Works

When you look at these images yo will have to concede that Adelfo brings a better conditioning to the Thanksgiving table than many a competitor to the stage ;-)
In a way it's funny how the Internet has brought us all so close together and yet we still have so little in common, when we are not "on the line". I believe it was two weeks ago, when I almost missed my own radio show on Thursday, because I assumed there wouldn't be a SuppVersity Science Round-Up on a holiday. Literally in the last minute I thought, maybe you better check whether the US guys have a holiday, as well - and what should I say? You didn't! Today, I am just back from the office and do now have an 'evening off', 'cause today it's you (or at least ~65% of you, which is the relative amount of US visitors in the last week), who have a holiday that' leaving me somewhat clueless why you are giving thanks and I am not ;-)

In the end, it does not matter for me what the deeper meaning of Thanksgiving is, as long as I know that you spend the day with your loved ones, it's a day to celebrate and that's all that counts - so HAPPY THANKSGIVING! Enjoy Adelfo's short progress update and get your share of the holiday roast - even if it will have it's share in the 0.5kg the average college student in a 2006 study by Hull et al. gained during the Thanksgiving holiday (. I will make sure there is "Get Lean and Stay Lean Quickie" either on Sunday or Monday, just in case ;-)

Happy Turkey Day SuppVersity readers! 

I’m going to make this short and sweet since I know most of you will be celebrating the Thanksgiving holiday with loved ones and eating good food, because I know I will. I’ve been getting some comments and request from a few people for an update on my progress, and I know I have not done one in a while, so this will be just a quick update on my diet, training and progress pictures… I promise that’s all!
Figure 1: Adelfo's current total caloric intake and macronutrient ratio (left); Adelfo's latest progress pics (right) comparing photos from week 2 and week 7 of this contest prep (img. Adelfo Cerame Jr. 2012).
Trainingwise, I am still following the Hybrid of P.H.A.T. training using an RPE scale with 3 to 4 workouts per week depending on what day workouts land (click here to learn more about Adelfo's routine). In addition I am doing cardio twice a week: 9 laps around a trace. Everything is pretty much the same since I started in October - the aforementioned cardio is in fact he only addition I have made to my regimen at the beginning of this month.

One thing I do notice is that my carb intake is a lot higher this year and has not yet to change. By this time last year I was probably already at 125-150g of carbs. I never realized that I was able to maintain 200g of carbohydrates (which is big for me) for a long period of time while still dropping body fat. 

When I come to think about it, it's probably less that I could not do it, but rather that I never even gave the 200g of carbs per day a chance. Ever since working with coach Alberto, I’ve learned that dieting and listening to your body is like a game of wits, and sometimes, the best move is no move, at all.
Image 1: Progress picture (backshots) comparing week 2 and week 7 of this competition (Adelfo Cerame. 2012)
With regards to my training split, it’s still kicking my ass day in day out. I’m exhausted most days every time I stroll out the gym after a training session. I feel sore more than usual nowadays, and my muscles feel tight like I’m somewhat pumped all day long. After mentioning this to Alberto and maybe second guessing myself that it was just in my head; he assures me that it’s not in my head…
“Just pushing you a bit on the frequency tip which is important for an athlete of your level. We will go back and fourth with it, and you are NOT imagining what you feel dude. Your muscle are under constant turnover now, and because of this I think you will keep a much fuller look.”
Here is another conversation between coach Alberto and I, when I mentioned still feeling sore and tight but was feeling and noticing more density in my frame especially in my chest area because I feel that the chest area is my weakest body part…
“Yep! It was about time you rode the frequency train. It’s going to pay off! This week we are going to not change a thing, since we added more cardio. I want to cruise a bit this month December push a bit, but right now it’s coming off easy. We will have some good detail in your back by the end of the month.

So far so good, and given the new frequency you are working with I think you are going to really see you keep more even though you got leaner”
But yes… I am very pleased with my training and how everything is coming along. I am confident that I will be able to outdo my old self this coming March of 2013.

That’s all I have for this Thursday edition but since it is the holidays, just in case you didn’t get to read it last year. I wrote an article on “5 simple rules to survive the feast without too much damage” So for those of you who just started following my blogs; here is the link to the respective article.

Have A blessed Holiday SuppVersity readers!

Of the 1.8 New Year's Resolutions We Make Every Year, 23% Fail Within Two Weeks: A Humorous Scientific Outlook on the Fallacy of New Year's Resolutions.

Image 1: I don't know about this "smart ass" in particular, but I would assume you have had enough "smart asses" post their knowledgeable tips on their blogs to get along without another "12 useful tips for 2012" from me, right?
I guess at least those of you who have been following this "blog" (I hope that you would agree that the SuppVersity has become more than another "blog") have come to "know" me well enough not to expect me to provide you with the 1001 list of ten, or at it has become fashionable as of late, twelve super-duper congenial tips to achieve your goals in 2012. Change, and this is the one wisdom I want to give you to take along for the next year, change rarely is something that comes over night or is "triggered" by the adherence to any fixed plan. Change is the result of the accumulation of small steps, dx/dt, as we physicists would say, i.e. covering an infinitesimal distance (=dx) within an infinitesimal short timespan (=dt). If we now denote steps that take you further towards your goal as positive and steps by which you depart from your ultimate goal as negative than any year in which the integral over dx/dt would be positive, or in non-physicist terms, where the number of infinitesimal steps you have taken towards your goal was greater than the ones by which you have distanced yourself from what you want to achieve, a successful year! Consider that before you file 2011 as another "lost" year.

Enough smart ass new years advice for 2011!

But hey, didn't I say, I would not give you wise ass advice? I guess we should get back to science then... after all the "-versity" in the name of this site denotes that we are doing serious stuff here, doesn't it? So, take my hand and descend (for the last time in this year) with me into the archives of science. The first thing we hit on is an editorial from the most prestigious medical journal in the world, The Lancet, in which the contemporary editor of the journal has the following well-phrased advice for you (I did not say I would not provide you with wise ass advice from others ;-)
The opening of a new year leads all of us to take some stock of the past and to formulate a certain number of resolutions for the future, and the frame of mind which is thus indicated should be indulged in, but only with moderation. To spend too much time in thinking over what has gone by will interfere with the work that lies under our hand; to make resolutions that are too large and too numerous for our powers is to court disappointment. None the less every thoughtful man will use his past experience to guide him in the future both as to what he will do and as to how he will do it. (The Lancet. 05. January 1907)
Image 2: New Years Eve is for most of us the time, when we simply cannot ignore the necessity to make a change, any longer.
Somehow, this reminds me of some of the "best tips, tweaks, tricks" and, above all, "common pitfalls to avoid in 2012", I have been reading elsewhere around the web over the course of the last days. I mean we all know that the more good intentions we have, the more likely they are to never materialize into significant changes. Being aware of this circumstance, Judith Stoner Halpern who wrote the editorial to January issue of the not just as famous *rofl* International Journal of Trauma Nursing suggests that (Halpern. 2001) "perhaps the best New Year’s resolution that we can make would be to learn how to make a better resolution"

Interestingly, and this is probably the first thing that goes beyond "conventional new year's resolution wisdom", the first reason she invokes is the time of the year!
An easy answer is to blame January 1. For one half of the world, it falls in the middle of winter, and for the other half, the middle of summer. This is not the most opportune time to enact a dramatic change. The middle of a season often causes us to feel a lack of commitment; this may be part of the reason that ancient cultures chose spring or fall as the time to start anew. For some, January 1 may feel like an artificial time for change.
When you come to think about it, this is actually quite a reasonable argument. With the "winter blues" upon us January certainly is not the best time to "blossom". The neo-paleolithic folks many of us recently believe we are, we should better crawl up in our dugouts and set up our plan of attack in order to mimic the "ancient cultures" and start anew in spring.

Does understanding the psychology of change hold the key for success?

The question yet remains, how do we instigate a new-or restart? A possible answer may come from Freeman and Dolan's theoretical model of change that in turn is based on a previous model by DiClemente that has been extensively discussed in the scientific literature on psychotherapy. According to the model, the authors propose in their 2001 paper in Cognitive and Behavior Practice, there are 10 stages. Where the last one, maintenance marks the (temporary) achievement of preferably positive "change".

Figure 1: The psychology of change - an illustration based on the "revisited stages of change model by Freeman and Dolan (Freeman. 2001)
If you take a closer look at my graphical illustration, you will realize that you have (hopefully) already overcome the initial stages of
  • noncontemplation, where, in your everyday oblivion, you do not even consider making a change
     
  • anticontemplation, where you are trying to convince yourself that you are "just fine the way you are" or that it would be impossible to make a change, anyways
     
  • precontemplation, where you are thinking and often dreaming about what would happen if you were able to make a change
Interestingly, for most of us the realization that another year is almost over usually makes us go through these stages (many of you may skip the 2nd one, some may get stuck there), automatically. So even if you are not one of Freeman and Dolan's persons, chances are that you are now, as they put it "directly and actively considering change" and have "reached a point of readiness to engage in the change process." 

Sitting in your neo-paleolithic dugout - or, for those who have not been infected by the paleo-virus in the course of 2011, simply in your cozy home - it is now about time to lay out your plan of attack!
Action planning is the stage of change when the therapist and patient have collaboratively developed a treatment focus and treatment plan. The therapetnic process has begun and the patient is beginning to make plans on how change will occur. The key phrase with this group is, "I plan to change."
Now, I don't know whether you have a therapist, or not (note: this is nothing to be ashamed of - I would even count the people I know that are in psychotherpeutical care among the few relatively sane human beings which populate this planet ;-), are working with a trainer, nutrionist or just a good friend who will help you on your way. In the end, it will always be about your commitment to your plan to change and eventually your success. That you have to determine the latter based on the integral over the steps in the right and steps in the wrong direction is something I have mentioned before. Freeman and Dolans model, however, provides a theoretical framework to understand this sometimes annoying, often frightening and in many cases discouraging back-and-forth even better.
Figure 2: Reported success rates at different timepoints in the new year and at 2 year follow up (data based on Norcross. 1989).
What are typical New Year's Resolutions? I must admit that I was quite disappointed about the lack of scientific data on the real-world outcome of New Year's Resolutions. Similar to the previously discussed issue of holiday weight gain which turned out to be at least less pronounced than everyone would have it (cf. "Santa is Coming to Town"), there is almost no realiable, non-specific, i.e. not related to only one goal (mostly smoking cessation), scientific data that would proof that the majority of new years resolutions fail.

In one of the two peer-reviewed studies I could come up with (both based on the same dataset), Norcross et al. report that their 213 study participants "made an average of 1.8 New Year’s resolutions" (Norcross. 1989). Among those, smoking cessation (30%) and weight loss (38%) together accounted for two-thirds of the resolutions. Other non-idiosyncratic New Year's Resolutions revolved around relationship improvement (5%), reduction in alcohol consumption (2%), and an increase in monetary savings (2%). A cursory glance at figure 2 does yet suffice to see that the difference between the real and the commonly assumed "success"-rates is much less pronounced than in the previously cited case of holiday weight gain. With a 23% chance of failure after no more than 2 weeks and a drop out rate of  57% after three months, chances that the average 16-75 year old citizen of northeastern Pennsylvania is able to realize his resolutions for the new year really isn't very high. A reported (do we believe those guys?) success rate of 19% after 2 years is nevertheless more than what my personal observations would suggest.

Lapses are integral parts of change - accept them work, through them, or fail

Image 3: If your New Year's resultion incorporates letting go of junk food, thinking of Mark Haub, the "Twinkie Diet Professor", probably would not be one of the "behavioral skills" to incorporate in your mental toolbox.
Let's assume you are a carbohydrate-addict and decided to cut back on carbs in the next year. Do I see you tremble in apprehension? Well, this is actually an apprehension of the prelapse phase, a phase that is "characterized by active and often overwhelming cognitions related to the reversal of the changed behavior" the carb-junkie you are, even the thought of having to put down your twinkies and dingdongs (whatever the latter may be) is getting you all psyched up. If it was already January the 1st, this would be the moment, when you are eating your eggs and bacon for breakfast, look at the cereals your brother is shuffling down his throat and think to yourself: "How can I possible endure that for the rest of my life?" Then you remember the words of the mighty paleo guru Robb Wolf to "give it a shot for thirty days" and gag down the last piece of bacon.

Psychotherapists refer to simple tricks like this as "behavioral skills", i.e. (mostly cognitive) techniques by which you can "short-circuit the prelapse before it leads to the old behaviors."

Figure 3: Successful and unsuccessful strategies to stay on track; * indicate statistically significance for success (data based on Norcross. 1989).
Which "behavioral skills" are most helpful? In the aforementioned study, Norcross and Vangarelli also analyzed which methods the participants successfully (figure 3, green) and unsuccessfully (figure 3, red) applied to achieve their aims. As you can see planning ahead (contingency management), managing "dangerous" stimuli, exercise (obviously not the way to distract yourself from the temptations if your new years resolution was to exercise more) and, above all, taking one step after the other, were the most effective strategies in the toolboxes of the 213 study participants, of whom only 18% said that "nothing hindered their resolution". Among the remaining 82%, most invoked their own lack of willpower (34%) as the fundamental obstacle. 16 subjects found that the realization of their resolution was not compatible with their lifestyle and 8 maintained that they had not been serious enough about their resolution.
(Un-?)fortunately, you are human and thusly destined to let reason go and fall back to old, oftentimes bad habits. So, there will come a day, when you will be sitting next to your meanwhile "no longer so loved ones" (after all, they are allowing themselves to eat all those jummy junk right next to you at your table ;-) and stare at the twinkies and dingdongs they are indulging. Suddenly a thought crosses your head: "Wasn't there this funky professor who lost a ton of weight on the twinkie diet?" You reach out and, probably much to the secret delight of your "formerly loved ones" who have been jealous of how fast you have been losing weight in the course of the last weeks, grab one of the twinkies that have been waiting for so long for you to take appropriate care of them... I guess I don't have to tell you the rest of the story, do I?

What is important, though, is that whenever lapses like this happen is that you always remember that no matter how many twinkies you may have eaten, how many training sessions you may have skipped, and/or how many cigarettes you have smoked, it is still your choice:
  • You can either return to the anticontemplative phase by persuading yourself that you could shed off the extra points just as well on twinkies and dingdongs - and even if that would not work, why would you have to make a change, in the first place? After all, you feel "fine just the way you are"!
     
  • Or you can analyze what triggered your temporary loss of memory and inability to apply one of the various behavioural skills that have prevented you from "lapsing" before.
I guess, it is not difficult to tell that option #2 would be the way to go. You have to go back to the drawing board. Not to start all over again, but to develop new skills and cognitions and to practice old to make sure that your next dt/dx's will be positive again. In that the ability to accept your own fallibility and the insight that a bunch of twinkies won't ruin the admirable success of the previous weeks, may be one of the key elements that will eventually enable you to achieve your contemporary goals, maintain your success and reach for the stars.

Along these lines, I wish all of you, my dear silent and not so silent readers, your families and loved ones, a successful, happy and, above all, healthy year 2012.

Adelfo Cerame - Road to Wheelchair Nationals '12: From Man Boobs to Striated Pecs - Looking Back at 2011

Image 1: Looks like Santa's sweet treats
just ricocheted off Adelfo ;-)
Although we are amidst the "holiday season" (you know the time of the year where the term off-season gets a whole new meaning ;-), there is one fellow who must obviously have read my blogpost about the not so amiable gifts Santa has in stock for some of us (cf. "Santa is Coming to Town")... judged by the pictures Adelfo has attached to the latest installment of his amazing "Road to Wheelchair Nationals 2012" series, Santa's sweet treats must have had a fat-burning, muscle-building effect on him. Well, at least this is what you could think, if you did not know how much hard work and dedication it cost him to get to where he is now. But, I guess I will let him tell you the whole story...

Without the "small" things the bigger one's "lose" all their meaning

It has been 12 months, now, hwen I got my medical release from the doctor... 12 months from the day I was finally able to leave the bed and go back to work... and eventually (!) go back to the gym and train! For almost all of 2010, I was confined to being bed-ridde. With the deep MRSA infected ulcer on my behind, I even had to lie on my belly - unable to sit, unable to move for almost a year.
Image 1-2: Looking back at December 2010 - All the abdominal fat and the man boobs that I accumulated after 12 months of being bed-ridden… I just hope that I will never have to go through that again.
That these memories are coming back now, is probably because New Years Eve is approaching. The last days of a year, where I have made a habit of reflecting on the little things that we usually take for granted. Looking back, none of this things, like being able to go to the grocery store, running errands or doing what I love the most, which obviously is going to the gym, was completely out of reach, back in 2010. Isn't it amazing how we always have to lose something until we appreciate its value?
Think about it, wouldn't  "Live life… cherish every moment of it… and be thankful for even the simplest things that this life has to offer!" be a much better new years resolution than the usual "I want to lose 5 pounds of fat!" or "I want to quit smoking"?
For me this (fortunately) temporary loss of mobility and, ultimately, freedom, marked another turning point in my live. I have ever since been trying my best to live life to the fullest, improve and better myself spiritually, mentally and physically. I have begun to cherish the simple things in life, constantly reminding myself that they could be taken away from me (and you!) at any moment. And for me, training, of all these little things, is the one I cherish the most: waking up in the morning, getting into the wheelchair and off the the gym to do the one thing I love the most is something I never want to lose again.

December 2010 to December 2011 = from man boobs to a striated chest

I don't know if you can empathize with the way I feel, when I look at the pictures from 2010, now. I mean, you know that about 8-6 weeks ago, I decided that I wanted to look "as stage ready as can be" at my 12-week mark (which actually is today) and today, after 12 weeks of intermittent fasting, eating whole "real foods", and training heavy and intense (plus minimal cardio and abdominal exercises) the result are eventually paying off:


Stats/Measurements
  • Weight: 141 lb.
  • Waist: 29 in
  • Arms (flexed): 17 ¼” in
  • Chest: 41 in
  • BF%: around 8% [at least that’s what my digital calipers read ;-)]
As you can see from the images from last year… I don’t have the best genetics in the world (I’m more on the endomorphic side of the body types), and I obviously let myself go (not of my choosing, but due to illness), but my point is: No matter what genetic barriers you think or feel you may have, or how far off you’ve let your body and health go, it’s not impossible to achieve the physique of your dreams, with just a little bit of hard work, consistency and balance.

I guess, I can say I’m pretty satisfied with what I have achieved so far and I’m definitely looking far better than I was at the my last show in April @ the INBF Natural Buckeye. Fortunately for me, I have 13 more weeks to improve on my physique and push myself even harder with my training and dieting.

3 things I want to try and improve on within the next 13 weeks…
    You think you could use some advice on your  training, diet and supplementation regimen from someone who knows what it takes to build muscle and lose fat? Reach out to Adelfo via Facebook.
  1. Vascularity… I want people to (figuratively ;-) throw up because they’re so disgusted with how many veins are popping out through my skin. Genetics aside, pushing my body-fat level to the lower limit will be the major factor in achieving that.
     
  2. Maintaining muscle mass and maybe even possibly gaining a little bit more… When you are dieting it is already difficult not to lose at least some of the fullness you have in the off-season. Putting on extra mass, on the other hand, is near impossible. Yet, although I have been dieting hard (and with visible results), I have been getting stronger throughout my prep and those strength gains are still coming... and though we all know that there is no 1:1 (or other quantifiable) relation between strength- and size-gains, I would expect to see at least increases in what people call "muscle density" or "maturity", if I can keep upping the weight on all my major lifts.
     
  3. Strength… I just don’t want to look the part, but I also want to be strong also. As I already mentioned, this is the first prep I’ve had, where I have not noticed any decline in strength. I partly ascribe this to the combination of intermittent fasting, raw and whole foods eating, and some of the training methods I have used from Rob Regish’s Blueprint, which have really taken the variety of my workout routines to the next level. And I hope that the latest addition of Anadraulic State, Creapure (creatine monohydrate), D-Pol (d-Aspartic acid) and Recycle (a herbal natural test booster) to my supplement regimen will help me with lifting (increasingly) heavy(-ier) lifts throughout the rest of my contest-prep.
For the time being, I am on my pre-planned last week of the year famine/detox. Those of you who have followed the whole series will remember that I have been quite skeptical about whether the theoretically sensible (cf. Famine/Detox Episode), yet for any bodybuilder totally counter-intuitive idea from Robb Regish's blueprint would work, but the results I had back in October were so convincing that I decided to make it a staple within every macro-cycle of my training. And now, after 12 weeks of intense training and dieting, the time seems to be right.
Image 4: Example of a "detox meal"
Recipe of the week: Spartan Detox Food (example meal) - Eat this (or a similar meal) 3x a day to benefit from a simulated "famine".
  • cucumbers, 
  • a handful of fruits, and 
  • a cup of vegetable juice from Trader Joe’s…
During my last detox, going extremely low on both calories as well as protein and fat worked quite well for me, but in general Rob's protocol allows for a  maximum of 1,200kcal (for you bigger guys out there) and <50g of protein, fill up the rest with veggies, fruit and a lot of water and you are good to go ;-)
During the 12 weeks, my body has eventually adapted to my diet and training, and is pretty much in an exhausted state, where gains in size and strength usually stall. In order for me to get my body back into a growth state, I have to shock the whole system by putting my body through a mild state of tissue breakdown with added stress (think of it as triggering the alarm). The mild tissue breakdown and added stress through training during the famine phase will accelerate the entire protein turnover cycle. So basically I want to get my body back into a phase where it feels like I just started lifting weights and training for the very first time in order to be in that growth state again, so that, even at an average calorie intake of roughly 1,400 calories per day, I can still maintain (or hopefully build on) the muscle

Final thoughts... at least for this year ;-)

Image 4:  No clue what "intermittent fasting is all about"? I suggest you start with reading the first installments of the Intermittent Thoughts, then (click here for Part 1, Part 2, Part 3 and more)
If there is one thing that I have really come to appreciate during the past weeks, it is yet neither the famine, nor the detox or the different training techniques I have learned. The one thing, I believe has made the biggest difference was intermittent fasting - all I can say is… I love it! The protocol is simple and easy to follow and I was able to tweak it to my liking by applying other methods that have worked for me in the course of the last 4 years of competing. And the results are mind-boggling. I mean, this has by far been the easiest prep I have ever had! Without being distracted with having to prepare meals, I got to focus more on training, school, and fun stuff like social events. Add to that the amazing results I have (and still am) seeing in the mirror and you know why I believe that “IF” is definitely something I can, and will do long-term.

I will leave it to that for today, and even the year 2011 and wish all of you a happy and safe New Year! And just in case you happen to be one of those people who like to make "New Year's Resolutions"… Good Luck! Let me know how that works out for ya in a week or two? Hahaha! Just kiddin'! But seriously… You shouldn’t have to wait till New Years to make resolutions and set goals ;-)

Santa is Coming to Town and You Better Beware of His Gifts: Fat Gain, Muscle Loss and Increased Mortality Rates.

Image 1: The "modern" image of the Coke-drinking Santa. Do you really believe he is one of the good guys?
Finally, December 24th is there! The day we have all been waiting for, to get together with friends and relatives and wait for the portly, joyous, white-bearded man in the red coat to deliver "his" gifts. Interestingly enough, the word "gift" in German designates "poison" and while those of you who have been following the SuppVersity news earlier this week may now be speculating that this could in one way or another be related to the millions of iPhones Santa is going to be dropping down the chimneys in the night to come (cf. Mobile Contraception), it seems unlikely that the electromagnetic radiation from the gadgetry could explain the statistically significant +4.65% increase in cardiac and a + 4.99% increase in non-cardiac deaths during the holiday season. After all, the data based on which David P. Phillips, Jason R. Jarvinen, Ian S. Abramson, and Rosalie R. Phillips conclude that "the Christmas/New Year’s holidays are a risk factor for cardiac and noncardiac mortality" is from the pre-iPhone era (Phillips. 2004).

Is Santa not the good guy, the Coca Cola ads made us believe?

So, if its not the radiation, what else could it be? Could it be Santa Claus himself? Is he haunting us, just as his robotic counterfeit in the distant future of the year 2999, where an evil Santa robot is after the blood of the protagonists of Matt Groening's and David X. Cohens TV series Futurama? Or is it a result of the consumption of too many of the Coca Cola bottles Santa is supposed to have in his bag?
Image 2: One really has to marvel at how the soft drink producers dissolve the enormous amount of sugar on the right in the small amount of dark brew on the left.
Did you know that the Coca Cola company alone sells 1.6billion (!) servings of Coke per day? With 27g of sugar per serving, this equals 43,000 metric tons of pure sugar. The average American, who consumes an average of 150 to 170 pounds of sugar each year, would have to live into his/her 558th year of age to eat or drink her way through this sugar mountain. And while I have no doubt that there actually are people out there who would do that withing 100 years, I am not quite sure which of the ailments of our sweet convenience society would strike him / her first and put a spoke in the sweet-o-holic's plans: diabetes, cancer, heart failure or stroke? What would you say?
Phillipps et al. who report in a follow-up study based on the same dataset from the holiday periods between July 1, 1973, and June 30, 2001 that there was an "excess of 42,325 deaths from natural causes above and beyond the normal winter increase" (Phillips. 2010), exclude the possibility that the increased mortality rate was simply a result of the bad weather conditions and related respiratory diseases:
Respiratory diseases. Respiratory diseases increase during winter, and patients weakened by respiratory diseases can die from cardiac diseases. The respiratory hypothesis is undermined by 2 considerations: (1) People dying from cardiac diseases with respiratory disease listed as a secondary cause of death produce a smaller holiday peak than do people dying from cardiac diseases alone: 3.51% versus 3.77%. (2) Interaction between cardiac and respiratory diseases cannot easily explain the twin mortality spikes on Christmas and New Year’s.
So, in view of the latest headlines related to "holiday weight gain" here at the SuppVersity and elsewhere on the web, the next best plausible explanation (which would in fact come back to the "Coca Cola < > Santa Connection" ;-) would be gluttony, right?

Holiday weight gain: Distinguishing fact from fiction

Before we jump to any premature conclusions, here, let's initially have a closer look at how much body weight Santa actually has in his bag for you.I mean, the perceived weight gain is enormous, right? Well, science is however not about perceptions and feelings and it should thusly not really surprise you that, according to a US study which was published in the prestigious New England Journal of Medicine (Yanowski. 2000), the "average" American (in this study represented by 195 US adults with a mean age of 39 +/-12 years) gains no more than 0.37kg, or, expressed in terms of the mean weight of the study participants, 0.5% during the holiday period from from mid-November to early or mid-January.
Figure 1: Percentage of normal weight, overweight and obese subjects with "major weight gain", as defined in absolute or relative terms (data adapted from Yanowski. 2000)
And while the average weight gain hardly is something to speak of, there are two other particularly intriguing findings of this study I do want to draw your attention to. The first one relates to the the data in figure 1. As you can see, the number of overweight subjects among those study participants with major weight gain (as defined as >3% of the initial weight) is particularly high. While only 7.9% of the normal-weight (American normal weight ;-) subjects gained more than 3% of their initial body weight 11.1% of the already overweight subjects did. Interestingly, the number of obese subjects was slightly smaller (7.5%). The latter is yet a physical necessity as there simply is a phyiscal limit to the amount of weight you can gain in a given period of time and 3% for a person with BMI>30 is obviously way more than 3% for someone who is only "overweight" (25 < BMI < 30).

The real problem is: The weight does not magically disappear

The real culprit is however that the weight people gain during last weeks of the year "is not reversed during
the spring and summer months", so that he researchers' concern that
[t]he 0.48-kg weight gain of the subjects in this study between September or October and February or March might not appear to be  clinically important and could easily go unnoticed by both the subjects and health care providers [and that] the cumulative effects of yearly weight gain during the fall and winter are likely to contribute to the substantial increase in body weight that frequently occurs during adulthood.
A 2006 by Hull may not only provide a hypothetical explanation for the non-reversibility of the (minor) weight gain (Hull. 2006), it also provides some insights into the true fallacy of "holiday weight gain": The minor increase in total body weight goes at the expense of concomittant increases in body fat and reductions in lean tissue mass.
Figure 2: Relative changes in anthroprometric measures over the holiday season; left axis - overweight / normal weight, right axis + figures - all (data adapted from Hull. 2006)
In the 82 college students from the Hull study, this fat promoting, muscle reducing "recompositioning" effect of the holiday season (Thanksgiving to New Year) was even so pronounced that the study participants actually lost -0.1kg of their total body weight. This was unfortunately a direct result of a +0.8 increase in fat mass and a -0.4kg decrease in lean mass. And what's more, the effect on fat mass was again more pronounced in those subjects, who were already obese.

Beyond candy, coke & co: Five additional reasons why Christmas is potentially deadly

In spite of the fact that these highly unfavorable changes in body composition are certainly not beneficial for anyone's overall health, it stands out of question that their effects would be cumulative and can thusly hardly explain the empirically validated increased mortality risk during the holiday season. In a 2004 comment on the aforementioned paper by Phillips et. al., Robert A. Kloner thusly proposes five additional hypotheses which could explain the potentially fatal side effects of the holiday season (Kloner. 2004):
    Image 3: If you do not want to be treated by "beginners" and unexperienced hospital personnel you'd better not get sick over the holidays; and in case you do, please make sure to "postpone your death" in order not to ruin everyone's holidays ;-)
  1. Inappropriate delay in seeking medical attention - best way out: don't wait until all the presents have been wrapped out, when aunt Mary chokes over her food
  2. Reduced levels of healthcare staffing or fewer staff members who are familiar with individual patients during holiday on-call schedules - best way out: better avoid getting sick in the first place if you do not want to be treated by the SCRUBS staff
  3. Increased emotional stress - just ignore your nephew when he starts crying because he did not get the Nintendo Wii he wrote on his wish list
  4. Decreased our of daylight - make sure to get as much of the little light there is during prolonged walks with the whole family (may also help cool down any raised tempers ;-)
  5. "Postponement of death" - tell your 127 year old uncle that he has been waiting so long now that it would be very inappropriate to die now and ruin everyones' Christmas celebrations
Well, I guess, now that you know about all the terrible things that could happen and the best ways to avoid them, it is about time to wish you, your family, friends and loved ones a happy (death-free) holiday season! And in case you need a break from the festivities, there is no Christmas break, here it at the SuppVersity ;-)

Beyond Warding Off Holiday Weight Gain: 250-1000mg of Freeze-Dried Ginger Reduce Visceral Fat Even When Rodents Are Fed an Obesogenic "High Fat" Diet.

Image 1: If ginger works only half as good in humans as it does in rodents, you can drink your way to a leaner and healthier you with Alisa Profumo's delicious low-carb "Healthy REAL Ginger Ale".
Zingiber officinale, or, in plain English, Ginger, is unquestionably one of the most remarkable plant rhizomes that is known to mankind. It has been used in various cultures for treating common colds or fever, to aid digestion, treat stomach upset, diarrhoea or nausea, to alleviate rheumatic disorders, gastrointestinal complications and dizziness, and, as of late, it has received quite some attention as a possible adjuvant to treatment modalities of cancer (Peirara. 2011). In a pretty recent study, the administration of 500 mg/kg zinigiber officinale to streptozotocin-induced diabetic rats (cf. related study in CLnA, the Omega-3 Variety of CLA), was able to partly restore the deteriorated glucose metabolism (Abdulrazaq. 2011), and a 2010 study was able to show that 6-Dehydrogingerdione, an active constituent of dietary ginger stopped the growth of breast cancer cells in the petri dish. "That is all very well", you may now be thinking, "but what does that all have to do with warding off the holiday weight gain?" Well, the answer lies in the results of a very recent study, which have just been published in the International Journal of Pharmacology (Malik. 2011).

Ginger reverses diet-induced visceral obesity and restores blood lipids to normal

Z.A. Malik and P.L. Sharma, two researchers from the Department of Pharmacology at the ISF College of Pharmacy in Moga, India, investigated whether the administration of 0.25-1g/kg body weight of dietary ginger (freeze dried powder that was made from fresh ginger juice; human equivalent would be 40-160mg/kg) would have any beneficial effect on the high-fat diet induced deteriorations in body composition, energy, lipid and glucose metabolism of male Wistar rats. For eight weeks, the scientists fed the rodents a diet that consisted of 33% normal rat chow, 33% Nestlé milk powder, 7% sucrose, and 27% tap water.
Figure 1: This is probably the lowest fat "high fat diet", I've seen in some time (data adapted from Malik. 2011) - ridiculous, but hey, if the diet had really been "high fat", who knows if the rodents would have gotten obese, anyway ;-)
If you take a look a the macronutrient breakdown of the "high fat" and the "normal diet" in figure 1, it is quite obvious that the former is - if anything - higher in fat than the latter, but by no means what any sane individual would consider a "high fat diet" (I really have to check myself not to start ranting against the "high fat diet induced whatever" in rodent models, again ;-) But be that as it may, ... the data in figure 2 shows that the milk powder and the sucrose were obviously enough to really fatten the rats up, profoundly:
Figure 2: Relative increases in body weight (BW), white adipose tissue weight (WAT), visceral fat weight and brown fat in rats on the "high fat diet" (data adapted from Malik. 2011).
With a whopping +417% increase in the total white adipose tissue weight, the poor rodents became profoundly obese. Their visceral fat depots (mesenteric, epididymal  and retroperitoneal) more than doubled (on average +150%), whereas the weight of their metabolically active brown adipose tissue increased by "only" 107%.
Figure 3: Relative changes in body weight (BW), white adipose tissue weight (WAT), visceral fat weight and brown fat in rats on the "high fat diet" who were supplemented with 250, 500 or 1000mg/kg ginger (data adapted from Malik. 2011).
The addition of 250mg/kg, 500mg/kg and 1g/kg body weight of the freeze-dried ginger juice (now obviously in powdered form) to the chow dose-dependently ameliorated the weight gain and reduced the weight of both the visceral, as well as the brown fat to level that were below those of the rats on the "normal" diet (cf. figure 3). Intriguingly, the "low" dose of 250mg/kg body weight turns out to be the most effective one, when it comes to the reduction of the epididymal, retroperitoneal and mesenteric visceral fat pads.
Figure 4: Relative changes in triglycerides (TG), total cholesterol (TC), HDL and total cholesterol to HDL radio in rats on the "high fat diet" and rats who were fed the HFD with 250, 500 or 1000mg/kg ginger (data adapted from Malik. 2011).
The addition of ginger to the diet also kept the blood lipids in check (cf. figure 4) and normalized the glucose response to an oral blood glucose tolerance test in the "high-fat" fed rodents. Other than the scientists had speculated, it had no effect on energy intake and did not increase the fecal fat content. The two markers of hepatic health, AST and ALT, which were measured in the study, remained almost unchanged - in the 250mg group there was even a -17% and -13% reductions in the respective transaminases (I am thusly amazed why the study has the words "anomalies after chronic administration" in its title).

How does it work and how effective is it?

Let's finally have a brief look at a) the potential mechanism by which ginger exhibits its fat-burning magic and b) how effective ginger would be, as compared to other, better known, "tools" to ward off weight gain or induce weight loss. To check whether the mechanism of action involves increased beta-oxidation, Malik and Sharmaa mixed an additional 30mg/kg of the beta-blocker propranolol into the high fat, ginger-supplemented diets of the animals - and as you can see in figure 5, the addition of the beta-blocker led to a profound reduction in the ameliorative / fat burning effects of the freeze-dried ginger powder.
Figure 5: Relative increases (vs. control on normal diet) in body weight (BW), white adipose tissue weight (WAT), visceral fat weight and brown fat in rats on the "high fat diet" supplemented with ginger, ginger + propanolol, or sibutramine (data adapted from Malik. 2011).
And as far as its effectiveness is concerned, ginger stands the comparison to the (in-)famous weight-loss drug Sibutramine, of which you will probably have heard that Chinese manufacturers of otherwise ineffective herbal weight-loss remedies like to mix it into their products (obviously without mentioning this banned ingredient on the label).

So, if we assume that these amazing results translate to humans, the addition of a few ginger rhizomes to your holiday diet could be a very effective tweak to ward off unwanted weight gain. And if your plans for 2012 include getting rid of the nasty love-handles you have acquired in the course of the past 12 months, you better get accustomed to the spicy, yet fruity flavor of the rhizomes of this perennial reed-like plant. You could, for example start out by following Alisa Profumo's delicious low-carb "Healthy REAL Ginger Ale in Minutes"-recipe on the Super Human Radio webpage (cf. image 1). And just in case you are too lazy to juice and / or freeze-dry some fresh ginger rhizomes yourself, you may want to consider buying a bag of Carl Lanore's  standardized ginger extract, which is also available on the Super Human Radio website.
