Studies on protein intake, such as amino acid tracer studies, provide rigorous mechanistic insights but are small due to funding and complexity.

“um and and they're really small by necessity just based on funding and complexity of doing these studies I mean these are amino acid labeled Tracer studies right where they give people various doses of protein and they look at muscle protein synthesis right and and so um again I'm not I'm not here to say that we shouldn't be doing bigger better studies but um the some of the studies that have been aimed at elucidating this are quite rigorous in terms of their their their mechanistic insights”
