Slim-Fast is a reasonable approach to dieting with convenient, grab-and-go shakes and bars. It's fairly easy to follow, but it's not very heart-healthy.
Nutrisystem determines portions, prepares and delivers your meals, and tells you what to eat and when.
On this diet, eat 5 Medifast products each day and one self-prepared meal. Medifast aids short-term weight loss, but isn't sustainable enough to last.
