I think it’s also stomach volume, which can change over time. Dedication and patience.
this is really true, too. my weight gain has been primarily lifestyle - overindulging over a couple of years really increased my eating capacity (bigger stomach, takes more food to feel full). that, combined with a slowing metabolism (elimination of exercise, but also just getting older) was the recipe for me.
if i gain about another 25 lbs i will be about 3x my starting size! so it's not all genetics
