I wonder if any of you guys has been listening to this episode of Peter Attia's drive. I've listened it twice and there are a few interesting concepts expounded there, when and how leucine triggers mTor in muscles, for how long, what's the best distribution of protein and with what quantities according to Layman's muscle-centric model. The DIAAS score, the 3 governing EAAS (Leucine, Lysine, Methionine), the underestimation of nitrogen requirement by the nitrogen-balance studies (Randd's model adopted as the official RDA) and the ideal 1.6 g/kg/d quantity of protein which is twice the adopted RDA. The effect of plant-based protein and the low absorption degree of some of them, like whey protein. The invalidation of the metabolic window concept for people who have been training after 6 months. The need of more protein adequately distributed for non-young individuals and more. I already knew Don Layman and especially the fact that his studies have been financed by the big protein corporation, but at 1:55 he explains why he had to fall back on this kind of financing.
