Low-Intensity Weight-Maintenance Program Keeps Pounds Off.

A weight-loss program that incorporates a maintenance intervention may help people avoid regaining the 2 to 4 pounds a year that is typical after weight loss. Results of a trial published in Annals of Internal Medicine found that a primarily telephone-based maintenance program modestly slowed participants’ weight regain. 
 
The 222 participants, obese outpatients (body mass index ≥30 kg/m2) who had lost at least 4 kg ( ≈ 16 lbs) during a 16-week group-based weight-loss program, were randomly assigned to the maintenance program or to usual care. The intervention, delivered by dietitians, included 3 group sessions that shifted to 8 individual telephone calls with decreased frequency of contact over 42 weeks, followed by 14 weeks of no contact. Group sessions addressed caloric intake, weight self-monitoring, physical activity, obtaining support from friends and family, and relapse prevention. Calls focused on patients’ satisfaction with outcomes, preventing relapse, social support, and self-monitoring diet and physical activity. The usual-care group had no contact except for periodic weight assessments.
