Not only did he devise a fast diet to lose about 10 kilos a month and lose 6 kilos in 3 weeks, the Fast 800 diet, but Dr. Mosley, famous for the Fast or 5: 2 diet, has decided to put his face on it.

Becoming the main doctor of a new British reality show ” Lose a stone in 21 days “, or “Lose 6.5 kilos in 21 days”. In reality Mosley selects a group of overweight or obese participants and follows them for 3 weeks.

During these weeks, participants are doing his Fast 800 diet.
An 800 calorie daily regimen inspired by Dr. Taylor’s Type 2 Diabetic Diet, an example of which can be found here.

With the Fast 800 diet, you lose more than two kilos a week, while eating only 800 calories a day.
Thanks to the Mosley program he proved that his diet actually allows you to lose 6 kilos in 3 weeks.

But how do you keep the results? 

According to Dr. Mosley, the Fast 800 diet should be followed for a minimum of two weeks and a maximum of 12.
Then switch to the “modified 5: 2 diet” version to maintain results.
That is, two non-consecutive days at 800 calories a week, and the other 5 days with a normal Mediterranean-type diet.

To find out how to follow the Fast 800 (or Very Fast 800) diet, you must first hear the opinion of the attending physician, and then follow the instructions you find here.
