行为体重控制计划建议坚持每日能量摄入目标，但也允许跨天摄入的灵活性。缺乏证据表明摄入量的一致性是否对体重控制很重要。目前的研究探讨了在行为减肥治疗的背景下，日常摄入一致性与体重减轻之间的关系，并检查了摄入变化与已知与体重控制成功相关的几个因素之间的关系。参与者（N = 283）参加了一个为期12个月的行为减肥计划，完成了24小时的饮食摄入量和心理措施的回忆。在治疗结束时，低摄入变异性和更大的体重减轻相关，但在连续分析中，变异性不能预测体重减轻，而不依赖于平均摄入量。有趣的是，与体重减轻<10%的参与者相比，达到体重减轻≥ 10%的计划目标的参与者的摄入量变异性较小，尽管各组的平均摄入量没有显着差异。结果表明，每日摄入量的一致性可能有助于一些人成功减肥。此外，体重管理和认知饮食限制的自主动机与治疗结束时的摄入量变异性呈负相关。需要进一步的研究来检查在行为减肥治疗期间限制摄入量变化的建议是否能改善长期的体重控制。
Behavioural weight control programmes recommend adherence to daily energy intake goals, yet also allow for flexibility in intake across days. Evidence is lacking as to whether intake consistency is important for weight control. The current study explored the relation between day-to-day intake consistency and weight loss in the context of behavioural weight loss treatment and examined the relationship between variability in intake and several factors known to be associated with weight control success. Participants (N = 283) enrolled in a 12-month behavioural weight loss programme completed 24-h recalls of dietary intake and psychological measures. At the end of treatment, low intake variability and greater weight loss were associated, but variability was not predictive of weight loss independent of mean intake in continuous analyses. Interestingly, participants who met the programme goal of ≥10% weight loss had less intake variability compared to those who lost <10%, although groups did not differ significantly on mean intake. Results suggest that daily intake consistency may facilitate successful weight loss for some. Additionally, autonomous motivation for weight management and cognitive dietary restraint were inversely related to end-of-treatment intake variability. Additional research is needed to examine whether recommendations to limit intake variability during behavioural weight loss treatment improve long-term weight control.
