Obesity results from the excessive accumulation of fat that exceeds the body's skeletal and physical standards. According to the National Institutes of Health (NIH), an increase in 20 percent or more above your ideal body weight is the point at which excess weight becomes a health risk. Today 97 million Americans, more than one-third of the adult population, are overweight or obese. An estimated 5 to 10 million
of those are considered morbidly obese.
