Reduced schedules of dietary self-monitoring are typically recommended after the end of behavioral weight-loss programs; however, there exists little empirical evidence to guide these recommendations.
We explored potential thresholds for dietary self-monitoring during a 9-month maintenance period following a 3-month weight-loss program in 74 adults with overweight or obesity (mean [SD] age = 50.7 [10.4] years, BMI = 31.2 [4.5] kg/m) who were encouraged to self-monitor weight, dietary intake, and physical activity daily and report their adherence to self-monitoring each week via a study website.
Greater self-monitoring was correlated with less weight regain for thresholds of ≥3 days/week, with the largest benefit observed for thresholds of ≥5 to ≥6 days/week (all p < 0.05); significant weight gain was observed for thresholds of ≥1 to ≥2 days/week, whereas no change in weight was observed for thresholds of ≥3 to ≥4 days/week, and weight loss was observed with thresholds of ≥5 or more days/week.
Results demonstrate that self-monitoring at least 3 days/week may be beneficial for supporting long-term maintenance, although greater benefit (in relation to weight loss) may be realized at thresholds of 5 to 6 days/week. Future research should investigate whether individuals who were randomized to self-monitor at these different thresholds demonstrate differential patterns of weight-loss maintenance.
在行为减肥计划结束后，通常建议减少饮食自我监测的频率；然而，几乎没有经验证据来指导这些建议。
我们在 74 名超重或肥胖成年人（平均[SD]年龄=50.7[10.4]岁，BMI=31.2[4.5]kg/m）的 3 个月减肥计划结束后的 9 个月维持期内，探索了饮食自我监测的潜在阈值，这些参与者被鼓励每天自我监测体重、饮食摄入和身体活动，并通过研究网站每周报告他们的自我监测依从性。
更大的自我监测与体重恢复较少相关，对于每周≥3 天的阈值，最大益处观察到每周≥5 至≥6 天的阈值（均 p<0.05）；对于每周≥1 至≥2 天的阈值，观察到显著的体重增加，而对于每周≥3 至≥4 天的阈值，体重没有变化，并且每周≥5 天的阈值观察到体重减轻。
结果表明，至少每周自我监测 3 天可能有助于支持长期维持，尽管在每周 5 至 6 天的阈值下可能会实现更大的益处（与体重减轻相关）。未来的研究应该调查在这些不同的阈值下被随机自我监测的个体是否表现出不同的体重维持模式。
