Abstract：
BACKGROUND: Dietary self-monitoring in behavioral weight loss programmes traditionally involves keeping track of all foods and beverages to achieve a calorie deficit. While effective, adherence declines over time. WW™ (formerly Weight Watchers), a widely available commercial weight management programme, sought to pilot an approach that permitted participants to consume over 200 foods without monitoring them.
METHODS: The current study used a pre-post evaluation design with anthropometric, psychosocial and physical health assessments at baseline, 3 and 6 months.
RESULTS: Participants (N = 152) were, on average, 48.4 (±12.3) years old, with body mass index (BMI) of 32.8 (±4.8) m/kg2 and 94% female. Mean weight loss was 6.97 + 5.55 kg or 7.9 ± 6.1% of initial body weight (ps < .0001) at 6 months. One third (32.6%) of the sample lost 10% or more of initial body weight. Significant improvements in hunger, cravings, happiness, sleep, quality of life, aerobic stamina, flexibility and blood pressure were observed. Attendance at group meetings, as well as decreases in hunger, and fast food cravings from baseline to 3 months were associated with achieving 10% weight loss at 6 months (p < .01).
CONCLUSIONS: Using an approach that does not require self-monitoring of all foods and beverages produced significant weight losses and other physical and psychosocial improvements.

摘要：
背景：行为减肥计划中的饮食自我监测传统上涉及跟踪所有食物和饮料以实现热量不足。虽然有效，依从性随着时间的推移而下降。WW™（以前称为WeightWatchers），一个广泛可用的商业体重管理计划，试图试行一种方法，允许参与者在不监测的情况下食用200多种食物。
方法：当前的研究使用了人体测量学的pre-post评估设计，基线时的社会心理和身体健康评估，3和6个月。
结果：参与者（N=152）是，平均而言,48.4(±12.3)岁,体重指数（BMI）为32.8（±4.8）m/kg2，女性为94％。在6个月时,平均体重减轻为6.97±5.55kg或初始体重的7.9±6.1%(ps<.0001)。三分之一(32.6%)的样品损失10%或更多的初始体重。饥饿的显著改善，渴望，幸福,睡眠,生活质量,有氧耐力,观察灵活性和血压。出席小组会议，以及饥饿的减少，从基线到3个月的快餐渴望与在6个月时实现10%的体重减轻相关(p<.01)。
结论：使用一种不需要对所有食物和饮料进行自我监测的方法可以显著减轻体重，并改善身体和社会心理。
