Adherence

Frequent self-weighing (weekly or daily) is associated with greater weight loss in weight loss trials and less weight gain in weight gain prevention trials compared to less frequent or no self-weighing.

If you are trying to lose weight or prevent gain, weigh yourself at least weekly, ideally daily. Do not let fear of the number stop you. The data shows that people who weigh themselves more often lose more weight or gain less. This is a behavioral tool, not a judgment. Follow the instructions given in your program, but understand that more frequent monitoring is linked to better outcomes.

Why this rating

Observational data from RCTs; strong associations but self-report bias and lack of randomized frequency manipulation limit causal certainty.
