Obesity: A Disease

Obesity is emerging as a health epidemic around the world. According to the Centers for Disease Control and Prevention, obesity is rapidly spreading across all regions and demographic groups. An estimated 97 million adults in the United States are overweight or obese. That figure represents more than 50% of the American adult population. Of this group, 11 million adults suffer from severe obesity.

Obesity is an excess of total body fat, which results from caloric intake that exceeds energy usage. A measurement used to assess health risks of obesity is Body Mass Index (BMI). BMI is calculated by dividing body weight (lbs.) by height in inches squared (in2) and multiplying that amount by 704.5. The metric calculation for BMI is kg/m2.
