Adherence
Moderate-intensity lifestyle counseling delivered by primary care clinicians and lifestyle coaches yields negligible net weight loss (~1.3 kg) over 24 months, primarily due to significant weight rebound after the initial 12 months when coaching frequency is tapered.
If you are relying on a primary care weight loss program that involves seeing a coach monthly for a year and then less frequently, do not expect significant long-term weight loss. This study shows that such moderate-intensity interventions result in negligible weight change (~1.3 kg) and often a rebound after the first year. To achieve meaningful weight loss, you likely need more intensive, frequent, or specialized interventions than standard primary care counseling provides.
Model-based estimates for 24-month mean (95% CI) weight change from baseline were −1.34 kg (−2.92 to 0.24) in Basic Plus... Larger initial weight loss in Basic Plus was attenuated by a ~0.5-kg rebound at 12 to 16 months.
Why this rating
Randomized controlled trial with intention-to-treat analysis, though the effect size was null.
