Why you're gaining back the weight section is both complimentary and contradictory to the last section of common mistakes. In common mistakes the author tells you not to check the scale so often, in why you're gaining it back, it's because you're not checking the scale enough. Then it repeats the issues with crash diets (this is why they don't work, I agree with this completely). There is a brief paragraph on emotional eating, and I really wish this was talked about even more, but it's not.
One afternoon, a few years later, Christopher came home and announced that he wanted to try a macrobiotic diet. He’d read interviews with people who claimed that this diet made them feel balanced and happy and he was intrigued. I’d heard (incorrectly, as it turns out) that macrobiotics was only for sick people and that fish was a requisite part of the diet. No way was that for me! He looked at me with that sweet face of his and said, “Alright, baby. I’m going to do macrobiotics, but you don’t have to.”
Loads of research demonstrates people who log everything they eat — especially those who log while they're eating — are more likely to lose weight and keep it off for the long-haul. Start tracking on an app like MyFitnessPal when the pounds start sneaking up on you. It'll help you stay accountable for what you've eaten. Plus, you can easily identify some other areas of your daily eats that could use a little improvement when it's written out in front of you.
Weight can affect a person's self-esteem. Excess weight is highly visible and evokes some powerful reactions, however unfairly, from other people and from the people who carry the excess weight. The amount of weight loss needed to improve your health may be much less than you wish to lose, when you consider how you evaluate your weight. Research has shown that your health can be greatly improved by a loss of 5–10 percent of your starting weight. That doesn't mean you have to stop there, but it does mean that an initial goal of losing 5–10 percent of your starting weight is both realistic and valuable.
