Adaptive vs Monthly Support for Weight-Loss Maintenance: A Randomized Clinical Trial

Authors' conclusion

In this randomized clinical trial, participants in both conditions were successful at maintaining initial weight loss 20 months after the end of a weight-loss program, but providing extended care on an adaptive schedule did not confer additional benefit vs the once-per-month static schedule. Future research should investigate whether more precise algorithms of high-risk periods for weight regain can be developed and whether these models can improve weight maintenance outcomes. Moreover, given success of participants in both conditions at maintaining initial weight loss, future research should also investigate methods of improving the implementation and dissemination potential of telephone-based extended care interventions.
