Almost two-thirds of Americans are overweight (BMI between 25 and 29.9), obese (BMI between 30 and 39.9), or extremely obese (BMI of 40 and above). An obese person spends $900 more a year in medical expenses than a person of normal weight. American adult caloric intake has risen from 1,854 to 2,002 calories per day over the past 20 years. This 148-calorie per day increase equals a weight gain of 15 pounds per year.
Cigarette smoking, followed by poor diet and physical inactivity, are the leading preventable causes of death in America.
