The effects of differences in meal frequency on body weight, body composition, and energy expenditure were studied in mildly food-restricted male rats. Two groups were fed approximately 80% of usual food intake (as periodically determined in a group of ad libitum fed controls) for 131 days. One group received all of its food in 2 meals/day and the other received all of its food in 10-12 meals/day. The two groups did not differ in food intake, body weight, body composition, food efficiency (carcass energy gain per amount of food eaten), or energy expenditure at any time during the study. Both food-restricted groups had a lower food intake, body weight gain, and energy expenditure than a group of ad libitum-fed controls. In conclusion, these results suggest that amount of food eaten, but not the pattern with which it is ingested, has a major influence on energy balance during mild food restriction.
在轻度食物限制的雄性大鼠中，研究了进餐频率差异对体重、身体组成和能量消耗的影响。两组大鼠连续131天摄入约80%的正常食物摄入量（这是在一组自由进食的对照大鼠中定期测定得出的）。一组大鼠每天分2餐进食所有食物，另一组大鼠每天分10 - 12餐进食所有食物。在研究期间的任何时间，两组大鼠在食物摄入量、体重、身体组成、食物效率（每摄入单位食物的胴体能量增加量）或能量消耗方面均无差异。与一组自由进食的对照大鼠相比，两个食物限制组的食物摄入量、体重增加和能量消耗均较低。总之，这些结果表明，在轻度食物限制期间，进食量而非进食模式对能量平衡有主要影响。
