Inspired by health guru Dr Michael Mosley's The Fast 800 book, this 7-day meal plan is designed for you to enjoy effortlessly losing weight while staying within the 800-calorie daily limit. Our weekly plans change, so you get plenty of variety if you’re wanting to do this diet for longer than a week. This is Stage 1 of our weight loss program, which we recommend to do for at least two-weeks to maximise and optimise results. When you’re ready to move on two Stage 2, check out our 5:2 Plans.
Why the Fast 800:
800 calories is the new magic number for dieting success. This calorie level will trigger a range of desirable metabolic changes to speed up weight loss in a manageable way. This calorie restriction is ketogenic in nature, and ensures dieters burn fat yet retain muscle mass. To learn more about the background, the benefits and research behind this diet, see our blog post The New Fast 800 Calorie Diet from Michael Mosley.
*This menu is a guide only and meals are subject to change without notice due to seasonality and availability this means macros could change. Note that in all our Fast 800 menus we aim to get as close to 800 calories per day but there may be some small daily variations (+/-). Meals can be eaten in any order & won’t affect results. Please check with your medical professional before undertaking any weight loss plan. Each plan will be delivered all at once.
