It’s the stricter version of the 5:2 diet that can help lower blood sugar levels and could reverse type 2 diabetes. Involving eating 800 calories a day for 8 weeks, here’s what three days of 800 calorie diet meal plans looks like
High blood sugar levels - millions of us have it, but many of us don’t know it and it’s led to not just a type 2 diabetes epidemic, but also a rise in prediabetes , the condition that precedes it. Could calorie restriction help? It worked for medical journalist, Dr Michael Mosley , whose TV show Lose a Stone in 21 Days with Michael Mosley in currently airing at 9pm on Wednesdays on channel 4.
In his book, The 8-Week Blood Sugar Diet , he shares the science behind the Blood Sugar Diet; Inspired by Dr Mosley’s own experiences as a type 2 diabetic (which he no longer is), the book’s aimed at helping those with diabetes, and those at high risk of developing it, lose belly fat and reduce and stabilise their blood sugar levels through modifications to their diet.

A stricter version of the 5:2 diet , the first stage involves an intensive fasting period - an 800 calorie a day plan for eight weeks (something he's gone on to write more about in his latest book, The Fast 800 which Dr Mosley has now turned into an online lifestyle programme ). Unlike a ‘soups-and-shakes’ type of diet that the NHS recently announced it will be prescribing to thousands of people in the UK who have the condition, it involves eating food based on the fundamentals of the Mediterranean diet .
And while he emphasises that individual medical guidance is key, and that no one diet will necessarily work for everyone ( see his contraindications here ) the evidence that radical calorie restriction works is strong.
What does a menu of 800 calories a day look like? It’s more than you think. Here’s an insight into the weekday meal plans, including a weekend option which features a brunch recipe combined with a more substantial supper.
