Adherence
Collaborative care models using trained medical assistants or external dietitians as weight loss coaches produce greater weight loss than PCP-led brief counseling, especially when combined with meal replacements or medication.
Ask your primary care office if they have a 'weight loss coach' (often a nurse or medical assistant) who can see you monthly. This collaborative model, where the doctor handles medical risks and the coach handles behavioral support, is more effective than seeing the doctor alone for weight loss.
GoodSupportsHIGH confidence
Together, the results of these trials suggest that obesity treatment provided by weight loss coaches from the practice (e.g., medical assistants) produces modestly greater weight loss after 1–2 years, compared to usual care.
Why this rating
Supported by multiple RCTs (Tsai, Wadden, Kumanyika, Ma).

- Intensive, multi-component behavioral interventions (12-26 sessions/year) delivered in primary care settings produce clinically significant weight loss (4-7 kg), whereas low-intensity brief counseling by PCPs alone yields negligible results.Good
- Combining behavioral counseling with pharmacotherapy (e.g., orlistat, sibutramine) or meal replacements significantly increases weight loss compared to counseling alone in primary care settings.Good
