Quite simply, obesity is the term for having a body weight (and body fat) greater than what is healthy. An individual becomes obese when he or she has developed a lifestyle of eating more calories than what is burned through exercise and other activities. Although individuals can learn to curb weight gain and control their diet and exercise habits, the fact that obesity is so widespread suggests that there are external and environmental factors that also contribute to the condition. Obesity is an epidemic in America today. According to the Journal of the American Medical Association, 64% of the U.S. population is overweight or obese.
