The above topic discusses Protein limits. A few questions on this: (1) What ARE the limits to usable protein? a)per meal b)per day (2)what are the signs/symptoms that one has exceeded these bounds(fatigue; temporary brain death/fog)? (3)The notion of an "amino acid pool"(ie. storage of aminos) seems questionable at best..
I have checked out a few studies re: assimilation rate of protein and, assuming one wishes to maintain a certain amount of muscle mass(through positive nitrogen balance), they would indicate that meals should be consumed no greater than the limit of assimilation so that amino acids are constantly present in the body. The post-prandial assimilation rates of various proteins would also indicate that fasting would lead to muscle catabolism(given no aminos present). A question remains to be answered: how much can be assimilated(ie. digested, converted into aminos and utilized for repair/growth of muscle tissue and not converted into glucose)? Many would contend that greater than 50 grams under normal conditions can be assimilated by the 'normal'(average weight/metabolic rate/physiology) male at a given time, Personal experience disagrees. Having attempted to consume greater amounts per sitting a great feeling of fatigue('symptoms' of excess?) arose, lasting for up to 2 hours after eating. This was on a VLC diet. Proportional to the amount of protein consumed. It would be interesting to 'know one's limits' on a scientific basis. P.S: I have investigated Leangains and the site makes claims it tends to confute: fast(yet take BCAAs). How is it fasting except in a loosey-goosey way when substances(aminos) are claimed to be avoided for 16 hour intervals, yet others(BCAAs....aminos) are not? I'm sure Cavemen didn't have bottles of BCAAs like Dorian Yates in their 'gym lockers'. Feedback please!
