I was wondering, exactly why if someone doesn't consume 1,5-2,0 grams/lb. of protein, protein every two hours etc. will lose muscle. If the body is never on catabolic state by eating any macronutrient, surely the body will not switch to protein for energy. Also, since the body can build only very, very small amounts of new muscle every day, protein needs can't be so incredibly high for that. Does anyone have a link for a proper scientific study, not sponsored by supplements manifacturers that proves that someone needs so much protein to maintain/grow?
