bangs15:
exercise is one of the most important parts of being a feedee.
no exercise may bring on weight slightly faster (you can't out-exercise a fattening diet) but they'll just look pregnant as all the fat is visceral.
if you want your feedee to have a "fat chick" body rather than thin arms/legs/face and a big hard belly, encourage a good amount of cardio. it'll probably make them live longer and not hate life while they're at it.
What if that’s what you’d like to see in a feedee, is to have a relatively average sized arms, legs and a sharp face, hell ideally a jawline still, with a nice big bulge of a belly? Like the standard overweight male physique of a beer gut on a woman? What kind of diet produces that?
