You are absolutely right, it is sad to say that nearly 20% of the people who have the surgery initially have success with losing the weight, however they fail to realize it is just a tool to be used for the first 9 months to a year, to jump start their weight loss, but as you say with out a change in lifestyle, education, nutrition and exercise, they will put the weight back on. I personally know several people, who took the surgery as a silver bullet, miracle cure if you would, and initially lost weight, but after 2 years are back to nearly where they started. I for one, risked my life to get where I am, and live my life every day in a healthy way, I continue to make sure through, diet and exercise, I keep my body working properly, could I eat 10 cheeseburgers, not all at once, but I could over the course of the day, giving me the same caloric intake I used to have, and that is what happens to these people, rather than eating 4-5 small meals spaced out through the day, they graze, eating constantly, stretching their stomachs, back to where they can eat more and more. I am currently working with several surgeons in my area, and a national support website, to help these people with an aftercare program through my company, that provides a 12 week, exercise and nutritional supoort, from personal trainers and dietitians.
