In 2012, Dr Michael Mosley introduced the intermittent fasting phenomenon to the world in the form of the 5:2 diet, where you eat 500 calories for two days a week and eat normally (2000 calories) the other five days.

Now, his latest diet program “Fast 800” has gone viral, offering a similar ethos to 5:2, but instead allowing users to eat 800 calories on their two fast days. So we can eat more and still lose weight? Sign us up!

Here, Dr Mosley explains exactly what the diet entails and why it’s so darn effective…

THE FAST 800 EXPLAINED

Since the launch of the 5:2 diet six years ago, there’s been a mountain of research into the benefits of intermittent fasting and calorie curbing and just how beneficial they really are. And because of this, we now know that upping the original 500 calories for two days to 800 has similar results.

“[Eating 800 calories] gave people the same metabolic benefits in terms of weight loss but it’s much more doable than the original 5:2,” says Dr Mosley.
