Adherence
High-frequency self-weighing (≥3 times per week) is a significant predictor of clinically significant weight loss (≥5% baseline weight) in commercial weight-loss interventions.
Weigh yourself at least three times a week. Do not weigh daily if it causes stress, but do not skip weeks. Consistency is the key predictor of success. Use the data to adjust your behavior, not to judge your worth.
GoodSupportsHIGH confidence
Weighing in at least three times per week... were associated with clinically significant weight loss for both male and female participants.
Why this rating
Large sample size (N=2113) and statistical significance (P<.001), but it is a retrospective observational analysis, not an RCT.
