If any of who have successfully lost weight, which programs worked best for you? I struggle with it. There are several programs which I may be interested in, I email them to answer questions, and they never respond, including Noom and Weight Watchers. I have used Nutrasystem in the past and had some success, but it was limited, their portions are full of fat, extremely tiny, and not terribly healthful. Has any tried a program which worked?
