ObjectiveReduced 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.MethodsWe 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/m2) 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.ResultsGreater 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.ConclusionsResults 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.

确定饮食自我监测的最低阈值以促进减肥维持

目的通常建议在行为减肥计划结束后减少饮食自我监测的时间表；然而，几乎没有经验证据来指导这些建议。方法我们对 74 名超重或肥胖的成年人（平均 [SD] 年龄）进行了为期 3 个月的减肥计划，并在 9 个月的维持期内探索了饮食自我监测的潜在阈值。 = 50.7 [10.4] 岁，BMI = 31.2 [4.5] 千克/米2）他们被鼓励每天自我监测体重、饮食摄入量和体力活动，并通过研究网站每周报告他们对自我监测的遵守情况。结果对于≥3天/周的阈值，更好的自我监测与体重反弹较少相关，观察到每周 ≥5 至 ≥6 天的阈值带来的最大益处（所有p< 0.05);当阈值≥1至≥2天/周时，观察到体重显着增加；当阈值≥3至≥4天/周时，观察到体重没有变化；当阈值≥5天/周时，观察到体重减轻。结果表明，每周至少 3 天的自我监测可能有利于支持长期维持，尽管每周 5 至 6 天的阈值可能会实现更大的益处（与减肥相关）。未来的研究应该调查在这些不同阈值下随机进行自我监测的个体是否表现出不同的减肥维持模式。
