SuppVersity - Nutrition and Exercise Science for Everyone

Unless you're planning to just sit, instead of cycle on your spinning bike, it is by no means sure if your performance well benefit or maybe even suffer from the use of AMPK mimetics and activators. Recently someone asked me on Facebook, whether AMPK activators like Lipoic acid (ALA), Berberine, Metformin, AICAR & Co wouldn't make excellent performance boosters. I pondered that question for some time and said: "If you are about to compete in a highly glycolytic sport, the opposite is probably the case." There's little question that supplements like lipoic acid are useful if you are an overweight type II diabetic. But let's be honest: How many of you fall into this category? As healthy, active individuals or even athletes, on the other hand, you should be aware that the ability of these agents to increase the glucose uptake and block the glyconeogenic pathways in the liver may easily make you run out of fuel during anaerobic activities like lifting or...

No, none of the 20 agents in the list below is going to do the work for you, but they could help you "conserve" the results, keep you lean on a bulk and/or avoid the hazardous Yoyo effect when you go off a die. It's actually normal that the introduction is the last part of an article I write. What's special about today's SuppVersity article is thus not that I write the introduction at the end, but that I did not really know what I would be writing here, when I set out to compile the unsorted (but not chaotic) list of potential anti-obesity agents below. All of them act by pathway(s) you as a SuppVersity reader will have read about before, most prominently AMPK , and the peroxisome proliferator receptors (PPARs), of which the blockade of the obesogenic PPAR-gamma pathway, which is the main working principle of CLA turned out to be the go-to explanation for the ability of these agents to block both the differentiation of adipocytes and the storage of tr...

When it's served like this, Gum Arabic looks more like a healthy snack than a weight loss adjuvant. I guess everyone who has already listened to the podcast of yesterday's show or was even able to listen live, will have noticed that the audio quality - yet not my German accent - have improved significantly, now that Carl and I did eventually switch to Skype instead of the landline. I know, you have been telling me that all along... be that as it may, unless my Internet connection hangs up for whatever reasons we will continue to do the SuppVersity Science Round-Ups via Skype from now on. Apropos, there will definitely be another show next Thursday (assuming that the world did not collapse by then ;-) Follow up on Gum Arabic : Dosing & mechanism In addition to that, I was actually presently surprised how much ground we were able to cover. Allegedly, we have gone way over the scheduled 60min, and I guess I could have said a couple of additional words on the Gum Ar...

Image 1: Can you really team up leucine (or HMB) and resveratrol to make tired mitochondria get a move on? NuSirt Sciences says "YES!" And in the dish and rodents it's actually already working. What happens if you marry a well-known AMPK promoter and exercise mimetic, with an even more prominent exercise adjuvant and nutritional mTOR booster? Will they neutralize each other? Think about it.... ok, now gimme your answer: What happens if you put resveratrol and leucine together? At first it does not really make sense, does it? Right, it doesn't, at least not unless you follow the same train of thought, the researchers from NuSirt Sciences . NuSirt? That rings a bell, hah? Yeah those were the guys who did a study on their 250mg leucine + 30mg vitamin B6 proprietary blend NuFit (see " Testosterone - 12% Drop /W 75g Glucose? Fat Loss - Adzuki, Leucine + B6 or HiMaize & More ") and actually, the leucine + resveratrol combination is sort of a spin-off of t...

Figure 1: Glucosamine composition of the chitooligosaccharide used in the study (data adapted from Jeong. 2012). Usually I try to avoid this term, as it seems to imply that there is, or at least soon will be a pill that would allow you to stay the lazy bastard you are now and still make it into your old age, healthy lean, attractive and vigorous, but in this case the word "exercise mimetic" is unquestionably what describes the effects of 6 weeks of oral supplementation with chitooligosaccharide described in a recently published paper by scientists from the Amorepacific Corporation Research & Development Center and the Kyung Hee University in South Korea best. I have to give props to my friend Carl Lanore the voice (and brain) of Super Human Radio who shot me an email on this issue, yesterday. A brief glance at the full-text was enough to realize that Carl who likes to pretend he was the idiomatic "blind man" with no scientific degree (I could hardly c...
