Weighing the evidence: benefits of regular weight monitoring for weight control.

We address the assertion that weighing obese patients in weight loss programs can be a source of distress and can lead to unfavorable outcomes. Examination of the relevant literature suggests that there is no evidence that weighing by weight loss participants is a cause of negative mood or of body dissatisfaction. Further, there is little evidence that negative mood states or body dissatisfaction lead to a poor outcome in weight loss programs. To the contrary, a number of studies consistently show that more frequent weighing is associated with better weight loss and maintenance. We offer suggestions for dealing with this issue in clinical practice.
