Review Meta Analysis
Isolated aerobic exercise and weight loss: a systematic review and meta-analysis of randomized controlled trials.
Aerobic exercise is a common nonpharmacological intervention for the management of obesity. However, the efficacy of isolated aerobic exercise at promoting weight loss is unclear. We conducted a systematic review and meta-analysis to evaluate the efficacy of isolated aerobic exercise programs in overweight and obese populations. ⋯ Moderate-intensity aerobic exercise programs of 6-12 months induce a modest reduction in weight and waist circumference in overweight and obese populations. Our results show that isolated aerobic exercise is not an effective weight loss therapy in these patients. Isolated aerobic exercise provides modest benefits to blood pressure and lipid levels and may still be an effective weight loss therapy in conjunction with diets.
