yes no doubt, but a can of coke and brown rice as long as they have the same amount of carbs will have the same effect on body composition period, absolutely no difference whatsoever. is the coke as healthy, hell no, but if fat loss/muscle building is your ONLY concern it is just fine
that's not correct... try to drink coke as your only carb source for some time... you'll end up with anemia, diabetics and lot's of fat tissue...
try to eat all your protein need from wheat or rice protein only, compare with high bioavailability protein sources like egg and fish... you can't compare at ALL!!!!
