在一名中年男性样本中，研究了最小干预策略对仅通过限制能量或仅通过锻炼在前一年保持减肥的影响。在最初一年的减肥结束时，节食者(n=44)和锻炼者(n=46)被随机分配到一种干预条件，包括每月邮寄的信息包和每月到每季度的电话联系，或者只接受评估的条件。与节食者相比，这项干预对运动者保持体重的影响要大得多。此外，节食者在维持体重的一年中表现出比锻炼者更多变的增重和减重模式。根据7天的食物记录和7天的体力活动回忆问卷，运动者报告说，在维持年度的开始和结束时，与节食者相比，锻炼者摄入的能量更多，花在剧烈运动上的时间也更多。我们的结论是，在使用最小接触策略的男性中，锻炼比饮食方法更容易保持体重控制，这些方法侧重于改变能量摄入，从而在总体保持和体重稳定方面都有好处。
The effect of a minimal intervention strategy on maintenance of weight lost through either energy restriction alone or exercise alone during the previous year was studied in a sample of middle-aged men. At the end of the initial year of weight loss, dieters (n = 44) and exercisers (n = 46) were randomly assigned to either an intervention condition, comprising monthly mailed informational packets and monthly to quarterly telephone contacts, or an assessment-only condition. The intervention had a significantly greater impact on weight maintenance in exercisers than it did in dieters. In addition, dieters showed a more variable pattern of weight gain and weight loss during the maintenance year than did exercisers. Based on 7-day food records and a 7-day physical activity recall questionnaire, exercisers reported a greater energy intake and a greater amount of time spent in vigorous activity relative to dieters at both the beginning and the end of the maintenance year. We conclude that exercise is easier to maintain in men using minimal contact strategies than dietary approaches to weight control focusing on modification of energy intake, with subsequent benefits in terms of both overall maintenance and stability of weight.
