Did some searching within the "ignorant, biased" medical community
...want to share some findings with y'all. For strength athletes, the *general* concensus for the average sized male is obviously varied, though the range that I see continually recurring is about 1.5-2.0g/kg... taken from the high end of the range, this does seem to indicate close to the 1g/1lb of bodyweight ideal, which most people will concur is adequate benchmark to start from, for all times other than serious calorie depravation (hardcore cutting, and whatnot)... keep in mind these findings below are general, and they are all for
strength athletes, which is about as close as we can assumably get to serious bb eh?
1.4-2.4g protein/kg (1)
1.5-2.0 g protein/kg (2)
1.2-1.7 g protein/kg (3)
1.8-2.0 g protein/kg (4)
1.4-1.8 g protein/kg (5)
since 1kg = 2.2lbs, even a 280lb (127kg) man (using the average from the high end of all 5 studies mentioned above,
1.98g/kg) is still theoretically eating shitloads of protein (251g), divided into the appropriate number of meals... shouldn't be a problem assimilating X number of grams depending on your goals as I stated above... so it makes more sense to worry that you've divided your daily protein up properly, don't skip meals, ensure proper post workout nutrition, etc... remember too that it only makes sense to increase protein even more when calorie cutting... I doubt too many serious studies can be found in this regard, because most people do not calculatedly starve themselves while training as intensively as bb'ers do... rather, they compensate by upping their ratios...hope this was some help.
