Why say 'make you fat'

Why say 'make you fat' instead of 'make you want to overeat' or 'increase your appetite'? Saying something makes you fat misses out the steps in between -wanting to overeat, overeating. To say something 'makes us fat' implies we have absolutely no control once the desire to overeat takes us.
