Sixty participants in a behavioral weight-loss program were followed up 4.5 years posttreatment. An inexpensive follow-up class was associated with the recruitment of the majority of participants, and 97% of the target sample ultimately volunteered. Participants lost 4.5 +/- 4.7 kg from pre- to posttreatment and 3.32 +/- 13 kg pretreatment to follow-up. The most successful weight-loss maintainers reported adhering to behavioral procedures and being more physically active. Participants also reported pursuing 3.0 +/- 1.8 different types of weight-loss programs after the behavioral treatment and wished to lose a further 25 +/- 18 kg at follow-up.
