The Fast 800 GLP-1 Recipe Book: On, Off & After by Dr Clare Bailey Mosley and Dr Jack Mosley — your food-first solution for safe, speedy weight loss, rooted in the science of the world-renowned Fast 800 programme.
Whether you are using GLP-1 medication, following a food-only approach, or have already reached your goal weight, this practical recipe book gives you the tools to eat well at every stage.
Featuring over 100 delicious, nutrient-dense recipes, the book prioritises protein and fibre to help silence food noise, protect muscle mass, and keep you feeling fuller for longer. Choose from three flexible meal plans:
- Food first – rapid weight loss through diet alone
- Low appetite – small, nutrient-rich portions ideal when medication reduces hunger
- Maintenance – sustainable habits to keep the weight off long term
Every recipe is designed for real life: simple ingredients, air-fryer options, batch-cooking ideas, and easy swaps. Extra protein and fibre top-ups, clear guidance, and expert tips from the Fast 800 team help you stay on track whether you are on the meds, off them, or beyond.
Written by GP and bestselling cookbook author Dr Clare Bailey Mosley (wife of the late Dr Michael Mosley) and Dr Jack Mosley, this is the essential companion for anyone seeking lasting results with a food-first approach.
