Bariatric surgeon explains why diet, exercise not enough to help people with morbid obesity

Howard Simon, MDThe idea that a morbidly obese person can achieve a healthy weight through willpower alone is outdated, according to Howard Simon, MD, director of bariatric surgery at Upstate. People with morbid obesity (with a body mass index above 40) have a metabolic disease too complicated to treat with just drugs, diet or exercise, he says, and most will regain weight lost through those methods. He explains why bariatric surgery, combined with behavioral changes, has a high rate of long-term success.
