Some correlates of the maintenance of weight lost through behavior modification.

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.
