Feasting then fasting – it's the controversial diet craze sweeping the world.
It claims to be the key to a healthy life, but can you really eat what you want most of the time and still lose weight?
The Fast Diet is the brainchild of Dr Mike Moseley, and it involves just that – fasting.
On the two fasting days, you're still allowed to eat but not much. You're allowed just 25 percent of a normal adult's daily intake.
On these fasting days you can either consume all your calories in one hit or spread them out in small meals throughout the day.
