Adherence

Intrinsic motivation and prior behavioral experience are stronger predictors of successful weight loss than financial incentives in low-intensity interventions.

If you are trying to lose weight, rely on your own internal drive and past successes rather than expecting external rewards (like money) to sustain you. Build routines, manage your environment, and seek social support. Financial incentives might help those with low intrinsic motivation, but they are not a substitute for behavioral change.

ModerateQualifiesMEDIUM confidence
Successful participants often stated that weight loss was its own reward, even without receiving incentives. Successful participants described more robust prior attempts at dietary and exercise modification, more active engagement with self- limitations, more substantial social support and a greater ability to routinise dietary and exercise changes than did participants who did not lose weight.
