Yes, nobody force feeds you (unless you are on a hunger strike in GITMO). You control what goes in. That's why I like Weight Watchers. The point system doesn't force you into foods you hate nor give foods that you like. You count the points. If you want several slices of pizza for dinner you make do with protein shakes until then.
My wife was two years after the baby up to a 14 from a 4 and after months on medifast went down to a 3 as did her sister and aunt also do well.
I'm up some and I am going to try eating between a 4-6 hour window and fasting the rest of the time (drinking water or maybe eating a 20 calorie salad).
