Do you feel that those who are successfully maintaining weight loss tend to transfer their obsession from food to something healthier? I'm using the word "obsession" not in a negative way, but for lack of a better word. For example, perhaps the successful maintainer who was a couch potato now teaches an exercise class 5 days a week. Or the former obese person that could barely walk across the room now runs marathons throughout the year. What about the person who was overweight all of their life but is now a Weight Watchers leader? Are there former morbidly obese folks who are motivated to obtain their degree in nutrition and become dietitians?
Perhaps this is an effective approach because the passion has been transferred from food to something positive, and the level of involvement and accountability makes completely going back to old habits more difficult?
