Details Condition: New Format: Paperback ISBN: 9781780723624 Publisher: Short Books Overview The Fast 800 is Dr Michael Mosley's science-backed programme for rapid, sustainable weight loss through intermittent fasting and calorie control. Building on the global success of the 5:2 diet, Mosley distils the latest research on time-restricted eating and low-calorie Mediterranean-style nutrition into one clear, flexible plan. Designed for real life, it suits complete beginners and experienced dieters alike, offering a structured route to losing weight, boosting energy, and improving long-term metabolic health without extreme restriction or complicated rules. About the Book The Fast 800: How to Combine Rapid Weight Loss and Intermittent Fasting for Long-Term Health sets out Dr Mosley's three-phase approach to sustainable weight management. At its core is the "800 calorie" model: research cited in the book suggests that 800 calories is a level low enough to accelerate fat loss and trigger beneficial metabolic changes, yet manageable enough to stick with. The programme combines a short, focused rapid weight-loss phase with flexible intermittent fasting patterns — including 5:2 fasting and time-restricted eating windows — that readers can tailor to their own routine and goals. Alongside the science, the book features delicious low-carb, Mediterranean-style recipes and menu plans created by Dr Clare Bailey, making the plan practical and enjoyable to follow day to day. Mosley explains the clinical evidence behind each element of the programme in accessible, jargon-free language, addressing not just weight loss but wider health markers such as blood sugar control, blood pressure, inflammation and mood. Whether readers want a short, intensive reset or a more gradual, long-term change to their eating habits, the book provides a structured but adaptable framework. It has become one of the most talked-about diet books of recent years, praised for grounding a popular weight-loss trend in peer-reviewed research rather than fad-diet promises, and for giving readers the tools to choose the intensity and duration that fits their own life and health needs.
