缺乏体育活动会导致体重增加。但只有22%的美国人经常运动。目的研究饮食结合有组织的有氧运动或中等强度的生活方式活动对体重、身体组成和心血管风险的短期和长期变化。设计自1995年8月至1996年12月进行为期16周的随机对照试验，随访1年。40名肥胖女性(平均体重指数[体重（公斤）除以身高（米）的平方]，32.9 kg/m(2)；平均体重，89.2公斤)，平均年龄42.9岁（范围，21-60岁），见于大学体重管理项目。干预措施：有组织的有氧运动或适度的生活方式；低脂饮食约1200千卡/天。主要结局指标：16周和1年时体重、身体组成、心血管风险概况和身体健康的变化。结果在16周的治疗计划中，有氧组的平均体重减轻8.3 (3.8)kg，生活方式组的平均体重减轻7.9 (4.2)kg(组内，P
