USE OF PERSONAL TRAINERS AND FINANCIAL INCENTIVES TO INCREASE EXERCISE IN A BEHAVIORAL WEIGHT-LOSS PROGRAM

Exercise is the best predictor of long-term weight loss. This study ev aluated two strategies for improving exercise adherence and long-term weight loss in obese outpatients. Obese men and women (N = 193) were r andomized to 1 of 5 treatment groups for 18 months: standard behavior therapy (SBT); SET with supervised walks (SW) 3 times per week; SET SW with personal trainers (PT), who walked with participants, made pho ne reminders, and did make-up SW; SET + SW with monetary incentives (I ) for completing SW; and SET + SW + PT + I. Both PT and I enhanced att endance at SWs, the combination producing the best adherence. Increase d walk attendance did not result in higher overall energy expenditure, however, and long-term weight loss was also not improved. Post hoc an alyses suggest that the level of exercise needed for successful long-t erm weight loss is much higher than that usually recommended in behavi oral treatment programs.
