10%(+) Reduction in Testosterone After Glucose and Whey Protein Shakes - Is the Classic #BB Shake Anti-Anabolic?

Written by | published on

We're talking about a cross-over study in adolescent subjects and acute changes but that's neither the only nor the most relevant reason you don't have to be afraid of the bodybuilding staple, now. In fact, a closer look at the data seems to suggest that we're talking about a 'protein-anabolic decrease in testosterone'... sounds odd? Well, here's how it may relate to your #androgenReceptors (AR) and eventually your gainz, irrespective of your age, by the way. I have previously addressed the possible ill effects of very high protein intakes on your testosterone levels - in particular, when those intakes are combined with a caloric deficit and, accordingly, reduced intakes of glucose and fat (re-read "True or False - High or Low Protein Intakes Have Profound Influence on Testosterone, SHBG, Estrogen, Cortisol & Co?" | here )... Now, a new study in Clinical Endocrinology  ( Schwartz 2019 ) shows that testosterone ⇆ protein/carbohydrate inter...

Will Adding 100mg of GABA to Your Whey Turn You into GH-ulk? RCT Finds 10x Higher Total Lean Mass Gainz, BUT...

Sometimes study results just seem too good to be true... I mean, who cares about total lean (including organ) mass when everything you can show off: strength, arms, and legs didn't grow appropriately? You don't? Well, the study is still interesting. Or did you anticipate that, in young-to-middle-aged training noobs GABA probably has to be cycled to keep its effects on growth hormone (GH)? I've previously told you about #GABA , I also highlighted that it's questionable whether its use as a growth hormone ( #GH ) booster is actually going to yield visible improvements in your physique... on the other hand, the GH response to workouts was - next to cortisol - the only hormonal correlate West et al. (see Figure 1, in previous article ) observed in the best and IMHO only decently well powered long(er)-term study investigating what Stuart Philips called "a hormonal ghost" ( Philips 2012 ), i.e. the contribution of the transient increase in growth hormone, testo...

MCTs and High Protein - One Will Turn You into a Metabolic Furnace, the Other Will Just Burn Money - #ShortNews 10/18

It's about time for some nutrition science news. For today's installment of the # ShortNews , I've picked two hitherto unpublished studies the main results of which have been presented recently as part of the  Proceedings of the Nutrition Society  Summer Meeting . The studies by Carr et al. and Maher et al. deal with the metabolic effects of two dietary nutrients you'll all be familiar with: protein and medium-chain triglycerides aka MCTs.

'Native' Whey, the Superior Whey? Transient Benefits on 'Recovery', No Size or Performance Gains in 12-Week RCT

Written by | published on

'Natural' whey is filtered right out of skim milk, 'regular' whey from the liquid 'waste" that accumulates in the cheese production - that's at least how the scientists in the study at hand define 'natural' - in the literature 'natural whey' often refers to whey concentrate/isolate vs. hydrolysates, ie. quasi-predigested protein with a completely different peptide content. I've discussed potential differences between 'native' whey protein and 'regular' whey protein supplements before. Unfortunately, the only evidence we've had, so far, has yet been the observation that it is digested even more rapidly than regular whey protein ( learn more in my 2017 article) - a mere increase in speed, however, doesn't necessarily translate to significant, let alone practically relevant increases in muscle and/or performance gain z ... without longitudinal studies, we're thus screwed when it comes to the interpretation o...
