Results of the recent Mind Your Health Project suggest that infusing standard behavioral treatment (SBT) for weight loss with acceptance‐based strategies enhances weight loss initially, but these effects fade in the years following the withdrawal of treatment. Even so, those receiving acceptance‐based behavioral treatment (ABT) were about twice as likely to maintain 10% weight loss at 36 months, and they reported considerably higher quality of life. Participants with overweight or obesity (n=190) were randomized to 25 sessions of SBT or ABT during 1 year and assessed at months 12 (ie, post-treatment), 24 (1 year post-treatment), and 36 (2 years post-treatment). Researchers found:
- Weight‐loss differences previously observed at 12 months attenuated by follow‐up, though a large difference was observed in the proportion of treatment completers who maintained 10% weight loss at 36 months (SBT=17.1% vs ABT=31.6%; intent‐to‐treat: SBT=14.4% vs ABT=25.0%).
- The amount of regain between post-treatment and follow‐up did not differ between groups.
- ABT produced higher quality of life at 24 and 36 months.
- Autonomous motivation and psychological acceptance of food‐related urges mediated the effect of condition on weight.
