Adherence
Continuing care (maintenance therapy) and regular exercise significantly improve the long-term maintenance of weight loss after both moderate and severe caloric restriction.
To keep weight off, you must continue the effort. Join a maintenance program or exercise regularly. Stopping after the initial loss usually leads to regain because obesity is a chronic condition.
GoodSupportsHIGH confidence
Patients who participate in a formal weight-loss maintenance program, exercise regularly, or both are likely to achieve the best long-term results.
Why this rating
Based on randomized trials showing better maintenance with these adjuncts.

More from this paper
- Moderate caloric restriction (1200-1500 kcal/d) combined with behavior modification produces an average short-term weight loss of 8.5 kg over 20 weeks, though patients typically regain one-third of this loss within one year.Good
- Very-low-calorie diets (VLCD, 400-800 kcal/d) under medical supervision produce approximately 20 kg of weight loss in 12-16 weeks, but long-term maintenance is poor without additional behavioral or exercise interventions.Good
