I've been reviewing weight-loss retreats around the world for 35 years. These are my go-to locations to drop a dress size while on holiday - including a UK staycation where I shed 10lbs in 5 days... and what's on the menu

If you're on the jabs, you could also learn a lot from a retreat: while Mounjaro et al will undoubtedly help you eat less, no medication can teach you the rule book for long-term health and balance.
