Rotundity is a pandemic in the United States. The number of Americans who are overweight and obese has grown alarmingly, especially many times, until more Americans are overweight than normal. In fact, more than 60 percent of Americans are now considered fat, and more than 30 percent of people are considered fat (e.g., fat over 20-30 of recommended weight). These statistics describe a sad public health situation. Obesity increases a person's risk of serious illness.
