Abstract

Behavioral interventions for obesity reliably facilitate short-term weight loss, but weight regain is normative. A high level of aerobic exercise may promote weight loss maintenance. However, adopting and maintaining a high level of exercise is challenging, and experiential acceptance may be important. The aim of this study was to pilot test the feasibility and efficacy of an acceptance-based behavioral treatment to promote moderate-to-vigorous physical activity (MVPA) among individuals who had recently lost weight. Adults (n = 16) who had recently lost ≥ 5% of weight were provided with a 12-week, group-based treatment. At 12 weeks, complete analyses indicated that participants had increased activity 69% (completing an average of 198.27 minutes/week of bouted MVPA, i.e., episodes of at least 10 minutes in duration). Medium-to-large effect sizes were observed for changes in process measures, including experiential acceptance. Future research to test this approach using an experimental design, a larger sample, and a longer period of observation is warranted.
