isn't there something that the body can only process 50 grams of protein at once? is it fine to have 80-90 gram shakes?
They do those studies based on the average couch potato, eating the average 2000 calorie RDI diet.
Michael Phelps eats 12,000 calories a day when he is training for swimming. He's not fat, and he's not a muscularly huge guy.
Do you think a lean 250 lb. bodybuilder can use only the same amount of protein as a 120 lb woman who's physical activity goes to the extent of a walk around the block once a day with her dog?
Really think about that. Think about the amount of muscle mass that BBer carries compared to that woman. Think about the activity level differences between the two. Do you think the protein needs between the two would be drastically different?
