|If you want to know exactly how your neighbors or rather your county did, check out the CDC's brand new County Data Interactive Atlas (may take some time to load), select your state and click on your county. Unfortunately, it's not exactly likely that you will be pleasantly surprised after all, places with rates below 6.5% (white on the map) have become rare, while those with 11.2% or more are becoming the norm.|
No reason to worry, though, my American friends! According to their own assessment, the CDC and its partners are working on "a variety of initiatives to prevent type 2 diabetes and to reduce complications in those already diagnosed."... you see,all is going to be good! Your well-meaning government is taking care of the problem ;-)
I guess that's enough sarcasm and useless statistics for the day. Let's get down to some serious On Short Notice business, now. And what would be more obvious than to start with something that's probably still not on the radar of the CDC or any its smart partners over at the NIH who are still promoting a high carb + low fat diet to people who can hardly tolerate the amount of carbohydrates in a TicTac. What I am talking about? The predispositioning effects of a fat-deficient toddler diet...
- Fat loving toddlers grow up to be leaner adults (Rolland-Cachera. 2012) -- To determine whether nutritional intakes in early life are associated with body composition and hormonal status at 20 years, a group of researchers from the University of Paris analyzed data from 73 subjects, who had been part of a two-decade-long prospective study (ELANCE, Etude Longitudinale Alimentation Nutrition Croissance des Enfants).Associations of specific factors that increase the risk of being obese in the kindergarten as based on another study that's also been published ahead of print in the online version of Obesity (Flores. 2012):The kids, now all young adults had been examined twice, at the age of 10 months and with 2 years. During the recent followup, the body weight, height, subscapular and triceps skinfold thicknesses, fat mass (FM), fat-free mass (FFM) and serum leptin concentration of the young adults (now twenty years of age) were recorded in order to identify associations between early nutrition and adult body weight.
- born to an obese mother + 240% risk
- gestational diabetes and gestational diabetes + 190%
- drinking tea or coffee between meals before bedtime at 2 years old +230% and drinking sugary beverages at kindergarten age at least weekly + 130%
- Latino or multiracial + 130% race ethnicity
- ever-attending center-based daycare -70%
- eating fruit at least weekly at kindergarten age -70
- maternal history of a prior newborn birth weight greater than or equal to 4000g -90%
The adjusted linear regression models Rolland-Cachera and colleagues used to analyze the data actually showed a couple of significant associations, the first one of which, i.e. the fact thatan increase by 100 kcal in energy intake at 2 years was associated with higher subscapular skinfold thickness (β=6.4%, P=0.002) and higher FFM (0.50 kg, 0.06–0.95, P=0.03) at 20 years, seems to stand in line with the hilarious calories-in-vs-calories-out hypothesis. However, these associations could also be related to the fact that early nutrition will program our satiety response, so that those programmed to be "good eaters" by a less nurturing diet in their earliest childhood will remain "good eaters", even when they switch to the energy-laden standard American diet.
Against that background, the second significant association the researchers observed, i.e. the fact that an increase by 1% energy from fat at 2 years was associated with lower subscapular skinfold thickness (−2.3% SF, −4.41 to −0.18, P=0.03), lower FM (−0.31 kg, −0.60 to −0.01, P=0.04) and lower serum leptin concentration (−0.21 μg l−1, −0.39 to −0.03, P=0.02) at 20 years appears to be even more important. After all, it looks like the Rolland-Cachera et al. had found the first relatively convincing evidence (not proof, yet) for the negative metabolic effect of early low fat diets in human beings:
"Low-fat intake in early life was negatively associated with body fat (particularly at the trunk site) and serum leptin concentration at 20 years, suggesting that early low-fat intake could increase the susceptibility to develop overweight and leptin resistance at later ages. These findings substantiate current recommendations against restricting fat intake in early life and open new directions for investigating the origin of obesity." (Rolland-Cachera. 2012)Now let's just hope that scientists are actually tackling these "new directions" and - more importantly - that the respective results are recognized by the public and incorporated into the "dietary guidelines".
- Study suggests: If you could chose only one, your intraworkout nutrition should be a carbohydrate not a protein supplement (Kazemzadeh. 2012) -- This is at least the authors' own interpretation of the results of a recent study that was conducted by three researchers from the Azad University and the Teheran University in Iran.
Figure 1: Changes in hormone levels from pre to post exercise (Kazemzadeh. 2012). If you focus solely on statistical significance you can be likewise mislead as, when you don't even check whether you findings are significant at all.Note: Just as most of these studies the participants did not consume breakfast before the resistance exercise session, which comprised six selected exercises: The bench press, biceps curl with barbell, side stretch, leg press, knee stretch, knee bending. If the study had been conducted after a regular breakfast ~2-3h before the workout, the study could have yielded totally different effects with respect to both, the blunted insulin, as well as the increased cortisol response. On the other hand, the GH spike in the protein group would most certainly have been lower as well. After all, the latter is - as you may have read in the SuppVersity Facebook News earlier today - basically only a means by which your body taps into its fat reservoirs to satisfy his acute energy demands and not strictly a way to protect lean mass (Gahete. 2012).I do still have serious doubts about the real-world significance of the temporary blunt in cortisol. After all, the immediate post-workout response is, in contrary to sustained elevations of cortisol levels for hours or days after a workout, associated with an increase, not a decrease in skeletal muscle hypertrophy (West. 2012) and in essence nothing else, but a physiological adaptation that's necessary to maintain stable blood glucose levels during strenuous workouts and sooth the early burst of inflammation after a workout. Moreover, despite being only borderline significant, only the protein shake did increase growth hormone (p=0.057), testosterone (p=0.52) and IGF-1 (p=0.51) levels during the workout.
This does not necessarily refute the benefits of carbohydrate supplementation during a workout, but if you insist on maximizing gains (not necessarily all lean I would guess) at all costs, it may be wise to consume a slow digesting protein + some fiber-laden carbs like oats 1-2h before a workout, to sip a light carbohydrate + BCCA drink intra- and wash everything down with another shake w/ whey protein and one or two bananas afterwards instead of just drinking some sugar water while you are lifting.
- Iron is a negative predictor of gastric cancer in humans and lowered hemoglobin and hematocrit levels induce insulin in rodents (Cook. 2012; Davis. 2012) -- While the alpha-tocopherol, beta-carotene cancer prevention study was a failure (at least with respect to the expected benefits of the anti-oxidants), there are still a couple of interesting side-findings.
Meat-Ology: The Link Between Red Meat, Cooking Techniques & Prostate Cancer
That said, subsequent adjustments for H. pylori and then gastric atrophy did not materially affect a majority of the estimates ...
"[...] the only exception was that the relationship between ferritin and GNCC [Gastric noncardia cancer] was attenuated There was little evidence for direct associations between iron metrics and H. pylori seropositivity or gastric atrophy (low pepsinogen I)—only serum ferritin appeared to share a relationship with these variables, and this relationship was stronger between ferritin and gastric atrophy." (Cook. 2012)So if "red meat is bad for you" it is probably not the iron content of the meat that is responsible for the observed associations of gastric cancer and high red meat intake in some previous studies (cf. WCR Fund. 2011).
And with respect to its effect on glucose metabolism, a recent rodent study has just shown that a reduction in hemoglobin and hematocrit due to a lack of dietary iron does actually impair, not improve glucose management in otherwise healthy rodents fed an iron-deficient diet:
Figure 2: Blood glucose, insulin and triglyceride on iron sufficient / deficient high sugar (AIN-76) or high starch (AIN-93) died (Davis. 2012)
[Moreover, hepetic]epatic gene expression analyses revealed a ~4- and 3-fold increase in the expression of glucokinase and pyruvate dehydrogenase kinase-4 mRNA, respectively, in the ID group on either diet compared to their respective PF [pairfed on iron sufficient diets] counterparts" (Davis. 2012)
- Vitamin C, D & E in health not disease - Only alpha-tocopherol shows negative correlation with markers of inflammation (Garcia-Bailo. 2012)-- A very recent study that has been conducted by researchers from the University of Toronto and the University of Guelph
did not find any relation between the novel and the old savior of the
human race, i.e. vitamin D and C, respectively and expression of
Suggested read: "Are Vitamin Supplements Bad For Me (1/2)? The wrong Vitamin E Supplements Increase Cancer Risk."
If you also consider the fact that IL-1RA (by the way not necessarily inflammatory), interferon gamma, IP-10, PDGF-bb and RANTES were the only out of 27 cytokines the researchers initially measured with high enough concentrations to be detect accurately in the 1007 subjects with a BMI of ~23 and a weekly activity level of ~7Met, these results do also provide substantial evidence that it would probably be worth spending more money on studies that investigate what it is that makes normal people healthy, instead of spending bazillions of dollars into the 1001st study on how people with XYZ (pt your favorite disease here) have low vitamin D levels *yawn*.
Check out the Website of the Reigning Canadian Kettlebell Biathlon Champion, Ameer Rosic for some workout videos Kettlebell swings restore and enhance back health and function (McGill. 2012) On the basis of electromyography, ground reaction forces (GRFs), and 3D kinematic data the researchers determined that kettlebell swings create a "hip-hinge squat pattern characterized by rapid muscle activation-relaxation cycles of substantial magnitudes (∼50% of a maximal voluntary contraction [MVC] for the low back extensors and 80% MVC for the gluteal muscles with a 16-kg kettlebell) resulting in about 3,200 N of low back compression." The way the swings activate the abs and the unique loading patterns of the posterior shear of the L4 vertebra on L5, which is opposite in polarity to a traditional lift could make it a valuable tool in re- and prehab. Kettlebell swing training improves maximal and explosive strength (Lake 2012) 21 healthy men were randomly assigned to either a kettlebell (KB) or jump squat (JS) training twice a week. The KB group performed 12-minute bouts of KB exercise (12 rounds of 30-second exercise, 30-second rest with 12 kg if lower than 70 kg or 16 kg if higher 70 kg). The JS group performed at least 4 sets of 3 JS with the load that maximized peak power—Training volume was altered to accommodate different training loads and ranged from 4 sets of 3 with the heaviest load (60% 1RM) to 8 sets of 6 with the lightest load (0% 1RM). The increase in maximum strength of 9.8%, as well as explosive strength (+19.8%) were identical in both groups Kettlebell training has "has potential for improving some components of MetS in middle-aged women." (Moreno. 2011): While the changes the author of the thesis observed in response to 10 weeks twice weekly kettlebell training did not reach statistically significance (probably due to the low subject size of N=6 physically inactive women, mean age (mean age 48.8y, BMI 31.8) the trends in " fasting glucose and body fat were encouraging and suggest that kettlebell training has potential for improving some components of MetS in middle-aged women." Kettle bell workouts can decrease blood pressure (Douglass. 2012): Eight resistance trained pre-hypertensive and HTN males saw statistically and more importantly clinically significant declines in blood pressure (to normal levels!) in the course of a randomized cross-over designed study which included 12 minutes of continuous two-handed swings (THS), three sets of a 6 exercise circuit (CIR), and a resting control (CON). Kettlebell training can improve strength, power and and endurance (Mannocia. 2012): 23 subjects (age 18-72 years) were required to perform a10-week kettlebell training program that took place in a group setting two times per week. Post hoc pairwise comparisons of assessments barbell clean and jerk, barbell bench press, maximal vertical jump, and 450 back extensions performance revealed significant time x group interaction and a main effect (p < 0.05) for the bench press, a trend toward a time x group interaction and a significant main effect for clean and jerk. These observations suggest "that kettlebells may be an effective alternative tool to improve performance in weight- and powerlifting". 10 min of treadmill running may burn more more energy, than a short 10-min kettlebell drill, but pro-anabolic & strength edurance effects speak in favor of 'the bells' (McGill. 2012): Only those who still believe in santa... ah, I mean the calories in vs. out theory of weight loss, will probably care, whether they are burning 12.5 or 17.1kcal/min and therefore this "advantage" would hardly be important even if the participants had not been sprinting part of their 10min on the treadmill just to make sure to achieve the prescriped (identical) rates of perceived exertion. And as usual, there is no reason, why you could not switch back and forth from one "drill" to another. If you just skip the hookers and the transdermal cocaine and take a regular bath, this may speed up your regeneration and propel your gains - if timepoint and temperature are spot on!
