Obesity  is a physical condition that results from excessive storage of fat in the body. Obesity has been defined as a weight more than 20% above what is considered normal according to the body mass index, which is calculated from an individual’s age, height, and weight. Current estimates place more than 35% of Americans in the obese category.  The primary reason for alarm is that obesity increases an individual’s risk of developing a variety of life-threatening diseases.  When obesity is clearly promoting life-threatening disease it is described as morbid obesity.
