Adherence
A one-year maintenance program following a 17-week weight loss intervention does not prevent or delay weight regain in severely obese patients compared to weight loss alone.
For severely obese individuals, adding a year of monthly maintenance sessions after a successful 17-week weight loss program (including a very-low-calorie diet) does not improve the likelihood of keeping the weight off compared to just doing the 17-week program. Focus on mastering the behavioral changes and dietary habits during the initial intensive phase, as extended professional contact did not provide additional benefit in this population.
This one-year maintenance program was not effective in preventing weight regain in severely obese patients.
Why this rating
Randomized controlled trial with a large sample size (N=201) and long-term follow-up (121 weeks), though not blinded.
