There is not much evidence about how diet strictness during weekends and holidays influence long-term weight loss maintenance. Our aim was to examine how dieting more or less strictly during weekends and holidays (vs. weekdays and non-holiday periods) influence weight loss maintenance.Participants (n = 108) from the Portuguese Weight Control Registry indicated whether they had a more or less strict diet regimen during weekends compared to weekdays. A similar question about holiday and non-holiday period' diet regimen was answered. Weight and height were measured at baseline and 1y follow-up. A 3% maximum weight variation defined participants as "non-regainers".General level on dieting strictness on weekends vs. weekdays (r = - 0.28, p < 0.01) and holidays vs. non-holidays (r = - 0.33, p < 0.001) predicted 1y weight change.Participants who reported being less strict on weekends (OR = 0.34, 95% CI: 0.15-0.81) were more likely to be non-regainers when compared with the ones who reported being more strict on weekends. Non-significant results were found during holidays (OR = 0.47, 95% CI: 0.20-1.09).Adopting a less strict diet regimen during weekends, when compared to weekdays, was a behavioral strategy associated with long-term weight management in our sample.
关于周末和节假日饮食严格程度如何影响长期体重维持的证据并不多。我们的目的是研究在周末和节假日（与工作日和非节假日相比）饮食更严格或不那么严格如何影响体重维持。来自葡萄牙体重控制登记处的参与者（n=108）表示，他们在周末的饮食是否比工作日更严格。关于假期和非假期饮食的类似问题也得到了回答。在基线和 1 年随访时测量体重和身高。体重最大变化 3%定义为“非复胖者”。周末与工作日相比（r=-0.28，p<0.01）和假期与非假期相比（r=-0.33，p<0.001）的饮食严格程度总体水平预测了 1 年的体重变化。与报告在周末更严格的参与者相比，报告在周末不那么严格的参与者更有可能是非复胖者（OR=0.34，95%CI：0.15-0.81）。在假期期间未发现显著结果（OR=0.47，95%CI：0.20-1.09）。与工作日相比，在周末采用较不严格的饮食方案是我们样本中与长期体重管理相关的一种行为策略。
