Evaluation of Weigh Forward: A group intervention delivered by dietitians and psychologists within a National Health Service specialist weight management service.

There is limited evidence of the effectiveness of non-surgical interventions for severe obesity. Our aim was to evaluate a group intervention delivered by a National Health Service (NHS) specialist weight management service to contribute to the evidence base and inform the development of future services. Participants in this prospective cohort study were patients attending NHS Grampian Specialist Weight Management Services.
