Most everyone I know that did a liquid diet, including Medifast, eventually gained back the weight... hate to be a downer, but that is how it is. It's hard to relearn eating habits and reintroducing solids , but not snacks requires more disipline than most of us have. I had Gastric Bypass Surgery not quite 3 years ago. I have gained back some... but I'd do it again in a minute. Although some of the weight has come back, my diabetes numbers and blood pressure have stayed low. Lose hair to due to malnutrition. Try taking biotin and zinc. I actually have more hair than before (but it was pretty thin to start with)
