There's this college kid in one of the gyms I go to that was studying for a test. Not sure which class but his study material recommended 0.8 grams of protein per kilo of bodyweight, 6 to 10 grams of carbs and I think .25 grams of fat. So for a 200 pounder that would be 72 grams of protein, 545 to 909 grams of carbs. His instructor aslo said athletes did NOT need additional protein. Lets hear it for academia!!!!! I know not everyone is a bodybuilder so lets say that amount of protein would be ok for the average couch potato but that many carbs would make most anyone FAT.
