Well, calories are units of heat value, and not everything one eats or drinks turns into fat, so it's best not to worry too much about it.
And protein is the main ingredient of a protein drink! Be careful not to eat to many sweets when dieting.
I'm burning a lot more calories by exercising at the sports center now, but we'll get to that later!
