The authors posed 2 questions in this randomized study of maintenance procedures in which participants were followed for 15 months after completion of a very-low-calorie diet: Would stimulus narrowing during the reintroduction of solid food, achieved by the use of prepackaged foods, improve weight losses and the maintenance of those losses as compared with the use of regular food? Would reintroduction of foods dependent on progress in losing or maintaining weight be superior to reintroduction on a time-dependent basis? Neither the stimulus narrowing condition nor the reintroduction procedure enhanced either maximum weight loss or maintenance of those losses. The stimulus narrowing condition appeared to be poorly tolerated; compliance and attendance were poorer in this condition than in the regular food condition.
在这项关于维持程序的随机研究中，作者提出了两个问题。该研究中，参与者在完成极低热量饮食后被跟踪观察了15个月：与使用常规食物相比，通过使用预包装食品在重新引入固体食物期间实现的刺激范围缩小，是否会改善体重减轻情况以及维持减重效果？根据减重或维持体重的进展情况重新引入食物，是否优于按时间顺序重新引入食物？无论是刺激范围缩小条件还是重新引入程序，都没有增强最大体重减轻或维持减重效果。刺激范围缩小条件似乎耐受性较差；与常规食物条件相比，这种情况下的依从性和出勤率更低。
