The research was performed to determine factors associated with weight loss maintenance. Factors examined included: a) physical characteristics, b) eating habits, c) self-motivation level and d) activity level. Subjects included 19 overweight females who had participated in a nutrition and exercise program held at Virginia Polytechnic Institute and State University. Two separate groups of subjects were contacted and interviewed. Group 1 (n=11) participants in a six week treatment program, consisting of a very low calorie (530 kcal) liquid diet, and a supervised exercise program corresponding to 60% VO₂ max for 30-40 min., 3 times/week. Group 2 ( n=8) consisted of an eight week treatment program, consisting of mild caloric restriction (1200-1500 kcal/day), and a supervised exercise program corresponding to 70% VO₂max for 30-40 min. Group 1 was 12 months post formal treatment and group 2 6 months. A questionnaire was developed and administered to the subjects. The first three sections were multiple choice concentrating on eating habits, behavior modification techniques, and self-motivation level (SMI). The last section was an interview session ascertaining information on activity levels. Of the factors examined, four were found to be prevalent for both groups: skipping breakfast and a strong appetite in the evening showed higher average weight gains, preplanning meals and higher self-motivation levels produced a lower average weight gain. Group 1 showed lower average weight gains for those individuals who joined another program and ate 3 meals a day. Group 2 showed individuals who had higher activity levels had lower average weight gains. Due to the low incidence of maintenance of weight loss, it appears necessary to emphasize maintenance strategies during treatment sessions. Also it appears necessary to individualize treatment for subjects due to the range of self-motivation levels. Booster sessions and/or continued treatment may be helpful for those exhibiting a low motivation trait. / M.S.
