Metabolic Syndrome: A Growing Clinical Challenge: Treatment

Treatment

Consensus panels including ATP III[45] recommend multidisciplinary therapeutic lifestyle counseling as first-line treatment for metabolic syndrome: increased physical activity (~30 minutes of brisk walking daily) in the 70% of Americans who are sedentary; a reduced-energy (~500-1000 cal/day reduction) low-fat, low-trans-fat, low-cholesterol, high-complex-carbohydrate (CHO) diet, possibly with isocaloric substitution of unsaturated fats for CHO[47] for weight loss in obese patients; and incorporation of physical activity, stress management, and group support for effective long-term weight management.[45]
