Providing portion-controlled prepackaged foods in a behavioral counseling intervention may promote more weight and fat loss than a standard self-selected diet.
The primary aim was to test whether providing portion-controlled prepackaged lunch and dinner entrées within a behavioral weight loss intervention promotes greater weight loss at 12 weeks compared to self-selected foods in adults with overweight/obesity. Other aims were to examine effects on biological factors, fitness, and meal satisfaction. One-half of those assigned to prepackaged entrées were provided items with a higher protein level (>25% energy) as an exploratory aim.
Participants (N = 183) had a baseline weight of 95.9 (15.6) kg (mean [SD]) and BMI of 33.2 (3.5) kg/m(2) . Weight data at 12 weeks were available for 180 subjects. Weight loss for regular entrée, higher protein entrée, and control groups was 8.6 (3.9)%, 7.8 (5.1)%, and 6.0 (4.4)%, respectively (P < 0.05, intervention vs. control). Intervention participants lost more body fat than controls (5.7 [3.4] vs. 4.4 [3.3] kg, P < 0.05).
A meal plan incorporating portion-controlled prepackaged entrées promotes greater weight and fat loss than a standard self-selected diet, with comparable meal satisfaction. Initial weight loss predicts long-term weight loss so these results are relevant to likelihood of longer term success.
在行为咨询干预中提供定量预包装食品，可能比标准的自主选择饮食更能促进体重减轻和脂肪减少。
主要目的是测试在行为减肥干预中提供定量预包装的午餐和晚餐主菜，与超重/肥胖成年人自主选择的食物相比，在12周时是否能促进更多的体重减轻。其他目的是研究对生物学因素、健康状况和用餐满意度的影响。作为探索性目的，将分配到预包装主菜组的参与者中的一半提供蛋白质水平较高（>25%能量）的食品。
参与者（N = 183）的基线体重为95.9（15.6）kg（均值[标准差]），BMI为33.2（3.5）kg/m²。180名受试者有12周时的体重数据。常规主菜组、高蛋白主菜组和对照组的体重减轻分别为8.6（3.9）%、7.8（5.1）%和6.0（4.4）%（P < 0.05，干预组与对照组相比）。干预组参与者比对照组减少了更多的体脂（5.7 [3.4] 与4.4 [3.3] kg，P < 0.05）。
与标准的自主选择饮食相比，包含定量预包装主菜的饮食计划能促进更多的体重和脂肪减少，且用餐满意度相当。初始体重减轻可预测长期体重减轻，因此这些结果与长期成功的可能性相关。
