Exercise, Diet & Bodyweight Control

Maintaining a desirable body weight throughout life is a popular, but elusive goal for most adults. At any one time, 50% of American women, and 25% of American men are dieting to lose weight, with only 5% of those involved in quick weight loss programs successfully keeping the weight lost off for five or more years. Obesity increases the risk for many diseases; most notably heart disease, colon cancer, hypertension, arthritis, kidney disease, and diabetes. Additionally, obesity often results in low self-esteem and social stigma. Education is the key to appropriate and effective body weight control. This lesson discusses the causes of overweight and obesity, and the key components (diet, exercise, and behavior modification) used in its prevention and treatment.
