Combined Therapy

Twenty-three RCT articles investigated the effects on body weight of a combination of a reduced-calorie diet with increased physical activity. The control groups used diet alone or exercise alone (346, 365, 375-377, 380, 384, 405, 434, 435, 445, 448, 469-475, 681, 684, 728, 729).  Of the 23, 15 were accepted and 8 were not considered for the following reasons:

• There was no exercise-alone or diet-alone comparison group (376, 405, 475, 681, 684, 728, 729); or
• The intervention was less than 12 weeks (474).
