LOSE-AF: Can Weight Loss Help Patients With Atrial Fibrillation?

The study intervention will be the referral to a commercial provider (CP) offering a Meal Replacement Programme. Briefly, participants will be referred to a nominated CP local counsellor who will set regular appointments during a period of 32-to-36 weeks to provide behavioural support, weight monitoring, and deliver formula meals. All counselors delivering the programme will receive, beyond their routine training and accreditation, specific information related to this study before being allocated patients.

Participants randomised to the control group will receive best usual care, consisting of a one-off face-to-face consultation on weight loss with a nurse at baseline (\~15 min), together with supporting written information.
