Face it, dieting is hard. If it were easy, there would only be one plan, it would work and no one would be overweight ever again. We eat to be healthy and to have energy. We eat because our body is convinced it is hungry. We eat because we see others eating and want to be social. We eat because we are happy, sad, mad, or indifferent. We eat because it is dinner time. We eat because it is Tuesday afternoon. Dieting does not address the whole picture, nor does it address the mechanics of the body. Diets, especially the extreme, hardcore, fad diets, are going to start off strong and then fade off after a week or two. Once the person stops the fad diet and returns to their normal way of eating, they regain what they lost and then some, starting off another swing in the vicious dieting cycle.
