Adherence
Logging food intake on at least three days per week is a significant predictor of clinically significant weight loss (≥5% baseline weight).
Log your food on at least three days a week. You do not need to log every single day to see results. Consistency in logging, even if partial, is a strong predictor of weight loss success.

Food logging at least three days per week... were associated with clinically significant weight loss for both male and female participants.
Why this rating
