DIET guru Michael Mosley is on a mission to get Britain fit with the blood sugar diet.
But who is the doctor, and what are his most famous meal plans? Here's what we know...
Who is Michael Mosley?
Dr Michael Mosley is a British TV presenter, journalist and scientist - who you may recognise from his regular appearances on The One Show.
He was born in Calcutta (now Kolkata), India, on March 22, 1957 - and hasn't always been destined for a career in science.
Michael studied Oxford's prestigious Philosophy, Politics and Economics (PPE) course, before working as a banker for two years.
He then moved onto medicine, and studied at London's Royal Free Medical School, now part of UCL, with the aim of becoming a psychiatrist.
When he graduated as a qualified doctor, Michael decided this wasn't for him - and joined the BBC's trainee scheme, as a producer, in 1985.
He's been working as a documentary maker and award-winning science journalist ever since. Most recently, he's been presenting Trust Me I'm A Doctor.
While presenting various documentaries, Michael has revealed that he shares brain traits with psychopaths - and suffers from chronic insomnia.
He has been married to GP Clare Bailey since 1987, and the couple have three sons and one daughter together. They live in the Chilterns.
Did Michael Mosley invent the 5:2 diet?
No, but he is widely regarded as the man who made it famous.
When Michael was diagnosed with Type 2 diabetes a few years ago, he was determined to reverse it.
His own dad, aged 74, died from complications of diabetes - and Michael wasn't about to follow in his footsteps.
He went on the 5:2 Fast diet, where you limit yourself to just 600 calories two days-a-week (500 for women) and eat normally on the other five days.
He lost 20lbs (9kgs) and claims to have reversed his diabetes by following the plan.
What is the blood sugar diet?
Michael's new meal plan is based on a low carb Mediterranean diet - with some fasting along the way.
The idea is to cut out starchy carbs, eat lots of green and coloured vegetables, plenty of protein and a moderate amount of healthy fats like olive oil.
Some dairy products, like unsweetened yoghurt, are also recommended because they help keep the dieter full for longer.
The diet is based on 10 years of research by Newcastle University and "has been shown to improve, even reverse, most cases of type 2 diabetes or prediabetes", according to the book's claims.
It has three main stages...
- BSD Fast 800: Limited to 800 calories-a-day, on the low-carb Mediterranean diet, for up to eight weeks.
- BSD 5:2: Five days of low-carb Med-style eating, and two days of 800 calorie fasting.
- BSD Way Of Life: A commitment to the low-carb Mediterranean diet, with intermittent fast days.
For those who can't fast, there's also the BSD Low Carb Med-Style plan, which involves adopting the new diet without counting calories. Happy days!
What can you eat on the blood sugar diet?
- BREAKFAST: Sample brekkies including plain yoghurt with fruit compote, scrambled eggs with tomato and chive, portobello mushroom 'toast' with goat's cheese and pine nuts, or two poached eggs with black beans and avocado.
- LUNCH: Mediterranean mezze platter, prawn pho soup, or chickpea salad.
- DINNER: Braised cod with veg, smoked mackerel and orange salad, spicy chicken and lentils, trout with crushed peas, mushroom risotto using cauliflower rice, or chicken with spinach and ricotta.
