What advice do general practitioners give to people living with obesity to lose weight? A qualitative content analysis of recorded interactions.

Weight-loss advice from GPs to patients with obesity rarely included effective methods, mostly communicating a general "eat less, do more" approach. Advice was mostly generic, and rarely tailored to patients' existing knowledge and behaviours. Effectiveness of brief weight-loss advice could be improved if GPs were given clearer guidance on evidence-based recommendations.
