SuppVersity - Nutrition and Exercise Science for Everyone

Either you buy one of the bazillion OTC test-boosters that will not do anything for your testosterone levels, but may have minimal effects on your libido; or, you get a script for the blue pills and accept that one of the side-effects of these proven libido-boosters is an increase in testicular testosterone production. If you were all Germans, I would probably be cracking a joke about the lead author's name "Spitzer", but in view of the fact that you aren't and that it would be a saucy one I will stick to the news-piece alone - it's saucy enough, anyways ;-) Actually you've heard Carl and me talk about the purported testosterone boosting effects of sildenafil aka Viagra on the Science Round Up in the past, but Mr. Spitzer and his colleagues from the Greenfield Health Center are the first to prove the potency of the testosterone response in male subjects who received "an optimized dose" (more on that later) of sildenafil, as well as its ...

Is there a Japanese  weight loss wonder supplement not even Dr. Oz knows about? And could it be more effective than Oz's raspberry ketones ? Sometimes the most inconspicuous articles turn out to be the most interesting ones. I mean, who would have guessed that a case report titled "Japanese herbal medicine for weight loss in a morbidly obese patient: A case report" would make it into the SuppVersity news? Being as heavy as tall, in this case 154.8 kg distributed not very proportional on a 157 cm frame with an 155cm waist, is - as unfortunate as that may seem - not exactly uncommon these days - even for a 22-year old woman. The words "japanese herbal medicine" and the line "her resting metabolic rate (RMR) increased from 2260 to 2440 kcal/day" (Haruta. 2013) the abstract mentions right after discussing her 10kg weight loss peaked my interest. How bad off was the subject? The subject had obviously been yoyo-dieting for years, when she was as ho...

Is the Paleo Diet unhealthy for healthy individuals? A recent thesis would suggest just that. Learn more about and make up your mind based on the last installment of the Science Round-Up and today's Seconds (img informedhealth.com.au) I hope you did not miss that the SuppVersity Science Round-Up will as of now always be starting early(-ier) at 12PM EST. If so, don't worry, you can still download the show and listen to Carl and me talking about the things you may be missing, the ones you get extra and those you would rather not have in your supplements and foods. Let's take silymarin , for example, as you have learned on the show, not all "liver assist", "liver clense" or "liver health" products are created equal. Most intriguingly, their ability to scavenge free radicals, as measured by the trolox assay, is not singularly dependent on the actual silymarin content, but will - as the data from the study Anthony et al. conducted (Anthony....

Yet another reason why calorie counting is not good for your sanity: The "average" sexual intercourse burns only 14 kcal more than watching TV.  and significantly less than a fast paced walk on the inclined treadmill. Luckily weight loss & maintenance is more complex than calories in vs. out, anyway ;-) "14" that's the SuppVersity figure of the number of extra calories you will expend when you and your significant other decide to have sex instead of sitting on the couch watching TV tonight. I got that figure from a paper my buddy Sean Casey from CasePerformance has brought to my attention. Published in the latest issue of the prestigious New England Journal of Medicine (Casazza. 2013), it discusses the 7 most commonly held "false and scientifically unsupported beliefs about obesity" the scientists identified in a thorough analysis of popular media and scientific literature. "The scientific community needs some more honesty" Whi...

Just to make sure you don't suffer from withdrawl symptoms until Adelfo posts the next update on his current contest prep , I thought I'd share a photo that shows where he is currently at - not bad for someone of whom a handful of you have been shocked to hear that he eats at least 200g carbs per day and ice-cream almost every evening, right? It's Thursday and before I'll get to a question on a very recent study I received via the SuppVersity Facebook page , I will brief you on the line-up of today's installment of the SuppVersity Science Round-Up on the Super Human Radio Network . By now, most of you should actually be familiar with the modus operandi: In case you cannot listen live at 1PM EST, you can always download the show ~2h later either from the "Physical Culture for Your Ears" menu in the sidebar of the SuppVersity , or right over at www.superhumanradio.com - obviously, you can also wait for tomorrow's SuppVersity Science Round-Up Seco...

As the data in the graphs at the bottom shows, only vigorous physical activity (right), yet not moderate (middle), let alone light physical activity (left) will help kids to stave off the bad visceral body fat, which increases their waist line from year to year. The photo in the background was by the way taken in 1989 on Orchard Beach, in the Bronx. If I remember correctly that's 6 years before the release of Nintendo's first "Game Boy". And yeah, I got one and it really doubled if not tripled my sedentary time! 7 minutes! That's the SuppVersity figure of the week and a number that should actually ring a bell with everyone of you who is following my advice and pays a daily visit to the SuppVersity Facebook Wall . "Seven minutes" that's what scientists from the University of Alberta and their Canadian colleagues believe would be the amount of "vigorous physical activities" our kids should get (Hay. 2012). I am not sure, if those sc...
