Does aerobic exercise have a positive effect on the reduction in resting metabolism associated with dieting?
Most available research suggests that moderate-intensity aerobic exercise training does little to diminish the usual 10-20 percent diet-induced reduction in resting metabolic rate (RMR). In fact, some studies indicate that combining aerobic exercise with a very low-calorie diet (less than 1000 calories per day) stimulates the body to conserve energy, thereby signaling the body to initiate the process of decreasing the RMR.
