Fast 800 Calorie

Winter Menu

Based on recent scientific studies, Mosley now advocates that 800 calories is the new magic number for dieting success.  He says this calorie level will trigger a range of desirable metabolic changes to speed up weight loss yet it’s still manageable.  This is why his new BSD Fast 800 diet recommends followers consume a Mediterranean style, 800 calorie diet every day for stage 1.  This calorie restriction is ketogenic in nature, and ensures dieters burn fat yet retain muscle mass.  Stage 1 is recommended for an initial two week period or longer (up to 8 weeks) for those who want more significant results.

Here at Dietlicious we have created our version of the Fast 800 Diet Plan.  Providing an average of 800 calories per day over a 7 day plan, we have four rotating weekly plans so you get plenty of variety. The Fast 800 diet is recommended by Dr Mosley for a minimum of two weeks.  If you’re looking to lose a large amount of weight, you can continue on stage 1 for rapid weight loss for up to 8 weeks.

When you’re done with stage 1 and want to move onto stage 2, jump onto our 5.2 diet page and select the right package for you.

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

* Note that in all our Fast 800 menus we aim to get as close to 800 calories per day but there will 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. This menu is a guide only and meals are subject to change without notice due to seasonality and availability this means macros could change. Each plan will be delivered all at once.

Don’t like some of the meals in the set plan?

We allow you to swap out up to 3 meals in any one plan. To swap items in your plan please name the meal and advise its replacement. Orders that do not advise a replacement meal will not have their swaps processed.

If you want to swap out more than 3 meals or choose your own meals then we suggest you also look at the Build Your Own Plan which allow you to customise and create your own plan from scratch.
