While average daily caloric intake in the US has remained stable over the past two decades, physical activity levels have declined. This has led to an increase in abdominal obesity, especially in younger women. Abdominal obesity, defined as a waist circumference over 34 inches for women or 40 inches for men, is an independent risk factor for health problems even for those who are not overweight overall. Increasing physical activity by 100 minutes per week was shown to reduce waist circumference in both men and women.
