Summary
Brief summary
Mean (± SEM) weight loss adjusted for baseline values was significantly greater in the meal replacement group (n=20) than the control group (n=21) at three months (4.7± 0.8 vs 1.3 ± 0.8 kg, P=0.007) and at six months (5.0± 5.2 vs 1.5± 5.2 kg, P=0.04) (Figure 1). The reduction in waist circumference was 1.4 cm greater in the meal replacement group than the control group at six months, but this difference was not significant. BMI reduced by 1.8kg/m2 in the meal replacement group and by 0.6kg/m2 in the control group (P=0.05).
