Summary

Background: Previous studies report 0.4-1.5kg of weight gain during the holiday season, which may contribute to annual weight gain. Purpose: To test whether daily self-weighing (DSW) can prevent holiday weight gain. Hypothesis: We hypothesized that daily self-weighing would effectively prevent weight and fat gain, and that individuals with overweight and obesity would respond most favorably to DSW.

Detailed description

A single-blinded randomized control trial: Adults (age 18-75y, BMI ≥ 18.5kg/m2) were randomized to either a control or daily self-weighing (DSW) group. There were 3 testing visits: pre-holiday (v1: within 7d before Thanksgiving), post-holiday (v2: within 7d after New Year's Day), and a follow-up (v3: 14 weeks after v2). The DSW group were given Wi-Fi scales that provide graphical feedback of daily weight. They were instructed to perform DSW during the holidays and to try not to gain weight above baseline weights. Anthropometrics were measured at each visit.
