Commercial products and programmes in obesity management.

RECOMMENDATIONS 1. For adults living with overweight or obesity, some commercial programmes exist that should achieve mild-to-moderate weight loss over the short or medium term, and a mild reduction in glycated haemoglobin values over a short term in adults with type 2 diabetes compared with usual care or education. 2. We do not recommend the use of over-the-counter commercial weight loss products for obesity management, owing to lack of evidence (Level 4, Grade D). 3. We do not suggest that commercial weight loss programmes be used for improvement in blood pressure and lipid control in adults living with obesity (Level 4, Grade D).
