Adherence
Interventions providing 12 or more contacts result in significantly greater weight loss than those providing fewer than 12 contacts.
When choosing a weight management program, prioritize one that offers at least 12 interactions (calls or visits) over the course of the year. More contact leads to better weight loss results, regardless of whether the provider is a doctor, nurse, or health coach.
GoodQualifiesMEDIUM confidence
Participants who had ≥12 contacts during interventions lost significantly more weight than those with fewer contacts... The association remained after adjustment for type of interventionalist.
Why this rating
Derived from subgroup analysis of a high-quality meta-analysis, though heterogeneity remains high.
