The Fast 800 programme is not recommended for the following:

• People who are underweight and/or experiencing an eating disorder, or have a history or suspicion of an eating disorder
• Children (under 18 years old)
• Type 1 diabetics
• Pregnant women, breastfeeding mothers or anyone undergoing fertility treatment
• People who have a significant psychiatric disorder or substance abuse
• People who are under active investigation or treatment, or have a significant medical condition affecting ability to comply with diet
• People who have had a recent cardiac event, myocardial infarction or cerebrovascular accident (<3 months previously) or other heart abnormalities
• People who have had uncontrolled heart disease, uncontrolled hypertension, or kidney failure
• People who are feeling unwell, have a fever, are frail or recovering from significant surgery (<6 months ago)
• People who are on insulin. This is to avoid a potentially dangerous drop in blood sugar (hypo)
• People who are on ‘flozin’ medication (known as SGLT2 inhibitors, taken to reduce blood sugars). This is to avoid the rare complication and potentially dangerous condition called euglycaemic diabetic ketoacidosis (DKA), where despite having normal or only mildly raised ketones the medication can mask a serious complication of diabetes requiring urgent attention

Please read our medical disclaimer for additional information.

The DIAMOND Study performed by Oxford University and Dr Clare Bailey looked at the feasibility of using an 800 calorie, low-carb, med-style diet as a treatment for people with type 2 diabetes.

After 8 weeks the average weight loss was 9.5kg, sustained over the course of the trial.

Results also included a significant drop in blood sugars, blood pressure and the use of medication.

As the Programme is guided, you are unable to pause or restart the course.

You can view content from previous weeks and you also receive a free four week trial of the monthly subscription service at the end of the 12-week Programme, to allow you to catch up on any missed content.

Please be aware that Week 1 starts the Monday following sign-up. The time in between sign-up and Week 1 is called the Prepare period, and is designed to give you time to have a look around the Programme, start planning your shopping list and recipes, try a workout or two, and get used to how the programme runs and works.

Please ensure that you are signing up according to how much Prepare time you would like before Week 1 commences – for example, if you would like a full week of Prepare time, please sign-up on a Monday or Tuesday, and if you would like to start Week 1 right away, please sign up on a Saturday or Sunday.

If you have any issues with the start date of your programme, please get in touch via our Contact Us form.

800 is the generally accepted number of calories used to achieve weight loss in scientific studies. Professor Roy Taylor, leading researcher into the reversal of type 2 diabetes, used 800 calories in his test group in the DiRECT Trial.

We have found that 800 calories is high enough to be manageable for most members, but low enough to trigger a range of desirable metabolic changes.

No, you don’t have to give up any of these whilst following the Programme although, obviously, we would certainly advise everyone to stop smoking as soon as possible, irrespective of their blood sugars.

Coffee and alcohol are still allowed on the programme although the calories in both of these drinks need to be included in the daily calorie limit (noting that alcohol is highly calorific).

A pint of beer or a large glass of wine contains 180 calories, so really best avoided or kept to a minimum.

The good news is that red wine is included in the Mediterranean-Style diet, so once you finish The Very Fast 800 and The New 5:2, and move onto ‘The Way of Life’ approach you will be able to introduce alcoholic drinks back into your lifestyle (we go over this in more detail in the Programme learning content).

Black coffee and tea are fine although you will need to include any milks in your daily calorie count.
