肥胖妇女（理想体重的140-180%）在代谢病房进行了研究，在1周的维持喂养，然后是5周的800千卡/天（液体配方饮食）。五名受试者参加了每日有氧运动的监督计划，三名受试者保持久坐不动。总的体重减轻在运动和不运动的受试者之间没有区别，但在运动的受试者中，更多的体重减轻来自脂肪，而较少来自无脂肪的质量。静息代谢率（RMR）在两组中相似地下降（约20%），即使运动受试者由于运动增加的能量消耗而处于更大的负能量平衡。总之，这项对照住院研究的结果表明，运动与食物限制相结合是有益的，因为它有利于身体脂肪的损失和保持无脂肪的质量。
Obese women (140-180% of ideal body weight) were studied on a metabolic ward during 1 wk of maintenance feeding, followed by 5 wk of 800 kcal/d (liquid formula diet). Five subjects participated in a supervised program of daily aerobic exercise and three subjects remained sedentary. Total weight loss was not different between exercising and nonexercising subjects but significantly more of the weight loss came from fat and less from fat-free mass in the exercising subjects. Resting metabolic rate (RMR) declined similarly in both groups (.apprx. 20%), even though exercising subjects were in greater negative energy balance due to the added energy cost of exercise. In summary, results from this controlled inpatient study indicate that exercise is beneficial when coupled with food restriction because it favors loss of body fat and preserves fat-free mass.
