Preview

The prevalence of obesity has increased markedly over the past few decades in the United States. This increase has occurred across all ethnic groups and all ages, including childhood and adolescence. After obesity has developed, long-term results from the treatment of obesity are generally poor. The importance of diet and nutrition in the prevention of the disease has been widely reported. An estimated 365,000 deaths occur each year because of suboptimal diet and activity habits. Dietary factors play a prominent role in 5 of the 10 leading causes of death for Americans: heart disease, cancer, stroke, diabetes mellitus, and cerebrovascular disease. The health benefits of physical activity and exercise are broad, strong, and well-documented. Health benefits appear to increase linearly with the total amount of physical activity.
