目的：在肥胖治疗期间，高脂肪密度食物组中食物种类的减少和低脂肪密度食物组中食物种类的增加与更低的能量摄入和更大的体重减轻有关，并可能有助于维持体重减轻。这项研究调查了国家体重控制登记处的2237名减肥维持者的食物种类，他们减掉了32.2 +/- 18.0公斤（70.9 +/- 39.5磅），并保持了至少13.6公斤的体重减轻。公斤（30磅）6.1 +/- 7.7年。研究方法和程序：在进入登记处时，登记处成员完成了一份食物频率调查问卷，从中评估了不同食物组的种类消费量。为了提供解释登记参与者饮食多样性水平的背景，研究人员比较了登记参与者和96名最近参加行为减肥计划并至少减轻了初始体重7%的个体之间的食物组多样性。结果：登记处成员报告说，在所有食物组中，他们的饮食种类都很低，尤其是那些脂肪密度较高的食物组。在6个月的减肥治疗后，与最近的减肥者相比，登记参与者在所有食物组中消耗的食物种类显著（p < 0.001）减少，除了水果和组合食物。讨论：这些结果表明，成功的减肥者在所有食物组中都选择了种类有限的饮食。限制所有食物种类的多样性可能有助于低能量饮食和长期保持减肥效果。
Objective: Decreases in variety of foods consumed within high-fat-dense food groups and increases, in variety of foods consumed within low-fat-dense food groups are associated with lower energy intake and greater weight loss during obesity treatment and may assist with weight loss maintenance. This study examined food group variety-in 2237 weight loss maintainers in the National Weight Control Registry, who had lost 32.2 +/- 18.0 kg (70.9 +/- 39.5 lbs) and maintained a weight loss at least 13.6. kg (30 lbs) for 6.1 +/- 7.7 years.Research Methods and Procedures: At entry into the registry, registry members completed a food frequency questionnaire from which amount of variety consumed from different food groups was assessed. To provide a context for interpreting the level of variety occurring in the diet of registry participants, food group variety was compared between registry participants and 96 individuals who had recently participated in a behavioral weight loss program and had lost at least 7% of initial body weight.Results: Registry members reported consuming a diet with very low variety in all food groups, especially in those food groups higher in fat density. Registry participants consumed significantly (p < 0.001) less variety within all food groups, except fruit and combination foods, than recent weight losers after 6 months of weight loss treatment.Discussion: These results suggest that successful weight loss maintainers consume a diet with limited variety in all food groups. Restricting variety within all food groups may help with consuming a low-energy diet and maintaining long-term weight loss.
