It was postulated that a nutrition-education programme was as effective an adjunct to a diet-based weight-loss programme as an exercise regimen. Forty-five obese female volunteers were placed on the same 5,000 kJ diet and were then assigned to each of three therapy groups: (i) an exercise group, involving three 1-hour exercise sessions per week (15 women); (ii) a lecture group involving a weekly 1-hour group lecture session (15); and (iii) a control group (15) who received only the diet and no activity. Weight loss, body fat loss (%) and daily energy intake reductions were equally reduced in the subjects in all three groups who completed the programme. There was, however, a significantly higher dropout rate in the control group. Taking this into account, the weight loss in the two test groups was similar and greater than that of the control group. We conclude that, in the short term, dietary education was as effective as exercise in promoting dietary compliance and weight loss.
据推测，营养教育计划作为基于饮食的减肥计划的辅助手段，与运动方案一样有效。45名肥胖女性志愿者采用相同的5000千焦饮食，然后被分配到三个治疗组中的每一组：（i）运动组，每周进行三次1小时的运动课程（15名女性）；（ii）讲座组，每周进行一次1小时的小组讲座课程（15名）；（iii）对照组（15名），只接受饮食，不进行活动。完成该计划的所有三组受试者的体重减轻、体脂减少（%）和每日能量摄入减少情况相同。然而，对照组的退出率明显更高。考虑到这一点，两个测试组的体重减轻情况相似，且大于对照组。我们得出结论，短期内，饮食教育在促进饮食依从性和减肥方面与运动一样有效。
