Ozempic, Wegovy, Mounjaro and Saxenda all promise weight loss, but how can we eat well when we're eating less?Taking weight-loss medication can be transformative as it offers liberation from a lifetime of dieting. But when you have a smaller appetite, good nutrition often takes a backseat - and it's common to miss out on the vital nutrients needed to build long-term health.

Drawing on twenty-five years of clinical experience, nutrition expert Ian Marber shares evidence-backed guidance, simple day-to-day menu ideas and supplement advice to help you eat well when eating less. Ian's holistic approach to wellbeing prioritises protecting muscle and managing side-effects so that you can build lasting health while losing weight.

The GLP-1 Handbook is your essential guide to understanding how the medication works, what to expect and how to adapt your diet and lifestyle - because weight loss should never come at the cost of your wellbeing.
