there have been quite a few studies recently looking into how much protein the body can actually use.
i think an indian study (india actually has some really good doctors, world class ones in fact as well as some really bad ones, the population is 1 billion remember) which ran multiple tests stated the body can only use between 20-40g of protein a day.
this website also confirms the theory

as you know a lot of the information out there is from supplement companies or bodybuilders who are either sponsored by or own supplement companies, therefore they want you to use as much of their product as you can so they tell you, you need 200-400g of protein per day 10 times what is actually needed according to these studies.
anyone know any more on this? i cant find the actual indian study but there was a lot of jokes made about it on the misc (strong racism among many members on the forum against indians and coloured people as well as jews, i have found), such as omg i just drank a protein shake with 50g of protein in it, shall i call an ambulance, am i going to die of kidney failure, etc.
it does sound plausible, without the use of chemicals, how much muscle do you think your body can build in a month? 1kg? so thats 250g in a week, roughly 35g of muscle per day.
how much protein, fat and carbs do you really think you need to make 35g of muscle a day?
could be a lot of substance to these new studies.
