Adherence
Weight management interventions delivered by non-medical practitioners (e.g., health coaches) are as effective as those delivered by general practitioners (GPs) or nurses.
You don't need to see a doctor for every weight management visit. Programs led by health coaches or nurses, especially when supervised by a doctor, are just as effective. Focus on finding a program with good support and regular contact.
GoodQualifiesMEDIUM confidence
Some evidence suggests that weight loss after weight management interventions delivered by non-medical practitioners in primary care (often endorsed and supervised by doctors) is similar to that delivered by clinician led programmes
Why this rating
Based on subgroup analysis of RCTs, with some heterogeneity in how 'non-medical' was defined.

- Behavioral weight management interventions delivered in primary care result in statistically significant weight loss (mean difference -2.3 kg) and waist circumference reduction (-2.5 cm) compared to no treatment or minimal intervention at 12 months.Good
- Interventions providing 12 or more contacts result in significantly greater weight loss than those providing fewer than 12 contacts.Good
