Using a mail and in-class distributed survey, data were collected from 721 members of Weight Watchers classes some 15 months after they reached their goal weights. The group averaged 73.2 kg (162.1 lb) before losing 19.0 percent of their body weight to reach goal weights averaging 59.6 kg (131.2 lb) in an average of 31 weeks. Fifteen months after reaching goal, 24.6 percent were below goal, 28.9 were within 5 percent of their goal, 17.5 percent were from 6--10 percent above their goal and 28.9 percent were 11 percent or more above goal. Those who maintained their goal weight, as opposed to those who regained, tended to have several things in common: they attended classes after reaching goal weight in the same locations and with the same lecturers that assissted their weight loss; they had lower initial weights: they conceived of themselves as 'overweight' when they were approximately three pounds above goal; they had improved self-concepts; they made more lifestyle changes supporting weight maintenance; and they continued, after goal, use of many of the techniques used to reach goal weight. Each of these factors has implications for planning for more programs designed to produce more lasting weight losses.
通过邮件和课堂发放调查问卷的方式，在慧俪轻体课程的721名成员达到目标体重约15个月后收集了数据。该组在平均31周内减重19.0%达到目标体重，目标体重平均为59.6千克（131.2磅）之前，平均体重为73.2千克（162.1磅）。达到目标体重15个月后，24.6%的人体重低于目标体重，28.9%的人体重在目标体重的5%以内，17.5%的人体重超出目标体重6% - 10%，28.9%的人体重超出目标体重11%或更多。与体重反弹的人相比，保持目标体重的人往往有几个共同点：他们在达到目标体重后，在与帮助他们减肥相同的地点、由相同的讲师授课的课程；他们初始体重较低；当他们比目标体重高出约三磅时，就认为自己“超重”；他们的自我概念有所改善；他们在生活方式上做出了更多有助于维持体重的改变；并且在达到目标体重后，他们继续使用许多达到目标体重所采用的方法。这些因素中的每一个都对规划更多旨在实现更持久体重减轻的项目具有启示意义。
