PURPOSE: To examine the effectiveness of a weight maintenance intervention focused on regular self-weighing after receiving a 12-week weight loss programme. METHODS: Quasi-randomized controlled trial of 3768 obese or overweight men and women. The intervention group (n = 3290) received two telephone calls, the offer of free weighing scales, encouragement to weigh themselves weekly and record this on a card. The main outcome was change in weight between 3 and 12 months. RESULTS: Using intention to treat analysis both groups regained weight; however, the intervention group on average regained 1.23 kg, whereas the control group regained 1.83 kg. Adjusting for covariates resulted in a mean difference of 0.68 kg (95% CI 0.12, 1.24) at 12-month follow-up. CONCLUSIONS: Encouraging people who have recently lost weight to weigh themselves regularly prevents some weight regain. BACKGROUND: Many overweight people take action to lose weight but most regain this weight.
