It’s important though to understand how much of a problem we are having with weight in the US. According to the National Weight Control Registry there are about 108 Million people on diets in the United States, and these dieters make about 4-5 attempts each year. There are about 220,000 people with morbid obesity, and the cost for bariatric surgery can range from $11,500 to $26,000. Another study by the American Journal of Preventative Medicine estimates by 2030 about 42% of US adults could be obese adding $550 billion to heath care costs.
