饮食限制是肥胖个体减肥的有效策略。最常见的饮食限制形式是每日热量限制 (CR)，即每天将能量摄入量减少为正常热量摄入量的 15-60%。另一种形式的饮食限制是间歇性 CR，其中包括 24 小时随意进食与 24 小时完全或部分食物限制交替。尽管这两种饮食对减肥都有效，但与另一种干预措施相比，其中一种干预措施是否能产生更好的体重和身体成分变化仍不清楚。因此，本综述研究了每日 CR 与间歇性 CR 对超重和肥胖成年人的体重减轻、脂肪量减少和瘦体重保留的影响。结果显示，3 至 12 周间歇 CR（分别为 4-8%、11-16%）和每日 CR（分别为 5-8%、10-20%）的体重减轻和脂肪量减少相似。相比之下，与每日 CR 相比，间歇性 CR 导致的无脂体重损失较少。这些发现表明，这些饮食在降低体重和脂肪量方面同样有效，尽管间歇性 CR 对于保持瘦体重可能更有效。
Dietary restriction is an effective strategy for weight loss in obese individuals. The most common form of dietary restriction implemented is daily calorie restriction (CR), which involves reducing energy by 15-60% of usual caloric intake every day. Another form of dietary restriction employed is intermittent CR, which involves 24 h of ad libitum food consumption alternated with 24 h of complete or partial food restriction. Although both diets are effective for weight loss, it remains unknown whether one of these interventions produces superior changes in body weight and body composition when compared to the other. Accordingly, this review examines the effects of daily CR versus intermittent CR on weight loss, fat mass loss and lean mass retention in overweight and obese adults. Results reveal similar weight loss and fat mass loss with 3 to 12 weeks' intermittent CR (4-8%, 11-16%, respectively) and daily CR (5-8%, 10-20%, respectively). In contrast, less fat free mass was lost in response to intermittent CR versus daily CR. These findings suggest that these diets are equally as effective in decreasing body weight and fat mass, although intermittent CR may be more effective for the retention of lean mass.
