Let's do another diet A vs. diet B comparison. Diet A is going to supply you with their foods, as well as their special drink or bars to eat, and tell you exactly when to eat them. You will lose - say - 30 lbs in two months. Diet B is going to attempt to help you learn which foods you should eat, how many calories you need to eat, why you need to eat them, and generally attempt to help teach you how to eat as part of a total lifestyle change that will allow you to make informed decisions about your nutrition. Diet B causes a slow steady weight loss of 8 -10 lbs per month for the next 6 months and the weight stays off because you now know how to eat properly.
