A calorie is a calorie, the advice goes. Eat too many ... gain weight. Eat fewer ... lose weight. But many believe weight loss is more than a calorie equation, with so-called new-and-improved ways to lose weight being ever popular. Americans spend an estimated $42 billion annually on weight loss foods, products, and services. With that much money at stake, it's no surprise there are an overwhelming number of "fad" diets and other weight-loss products on the market.
Over the past few years it has become clear that weight is an important health issue. Some people who need to lose weight for their health don't recognize it, while others who don't need to lose weight want to get thinner for cosmetic reasons. We understand that in some ways your weight is different from, for example, your cholesterol level or your blood pressure, because you can't see what these are by looking at someone. Many patients have had health care providers who approached their weight in a less-than-sensitive or helpful manner. Some patients may have had health care encounters in which they felt blamed, but not helped. Successful weight management is a long-term challenge.
