Dr Michael Mosley is known for many of the diets he created over the years, including the Fast 800 Keto.
The dieting guru has been speaking out about how a simple breakfast of eggs can actually help bring on ‘rapid’ weight loss in those who need it.

He was speaking on BBC Breakfast and introduced by presenter, and formerly Strictly contestant Dan Walker, who introduced his speech on a new ‘more manageable’ diet, reports the Express.
“Rather than cutting to 500 calories twice a week, Michael Mosley is now recommending 800 calories every day,” he said.
“Michael is here to explain – is this the next stage of the 5:2? How have you arrived at why – is it science that’s telling you 800 calories?”
Dr Michael replied: “Yes, it’s evolution if you like.
“I wrote the original book six years ago and that was mainly based on rat studies, and since then there have been quite a few human studies, and a lot of people have reported to me, and I’ve also spoken to the scientists involved In doing that research, and one clear thing is mainly people did well on it but struggled to eat 500-600 calories.
“When you look at what they ate, it was more like 800 calories.
“This is a staged process – the first stage being rapid weight loss, at 800 calories a day.
“You do the diet two to three weeks minimum, and some people continue to do it up to 12 weeks.”
The diet expert discussed the science behind the weight loss plan and said: “A study based in the north of England, it was 800 calories a day, for up to 12 weeks, and the average weight loss was around 14kg.
“There was another study done by Oxford [University] and they lost 10kg over a year.”
“Let’s have a look at what 800 calories would look like,” Louise Minchin commented.
“So this is your three meals for the day – it’s not much.”
“It’s ok – for breakfast I’ve got eggs and asparagus – the book has a range of recipes, but I’m a huge fan of eggs, eggs fill you up,” Dr Michael remarked.
“You can have scrambled eggs, boiled eggs, however, you want them.
“Sometimes I have eggs with ham or a bit of salmon.
“No toast I’m afraid, plenty of tea and coffee, plenty of fluid.

“I would encourage anyone doing a low calorie diet to drink lots and lots of fluid – because you’re going to dry out.”
The presenters noticed a lack of starchy carbs with the meals and Dr Michael revealed why: “It’s low carb, that’s one of the things that is clear now, that going on a low carb diet is a ketogenic diet and your body starts to burn fat .
“Your body runs on two different fuel systems – sugar and fat – and only when the sugar starts to go down do you switch to fat mode, and that takes 10-12 hours unless you’re on a relatively low carb diet.
“I wouldn’t recommend being low carb all the time, I think there are good reasons for eating carbs.
Veggies are all carbs, but they’re healthy carbs,” he added.
