There is some evidence that intermittent fasting can help you lose weight and improve your health. In fact, there have been a plethora of books on the subject. In the UK, this type of fasting diet became very popular after the BBC broadcast a (not very good) documentary about it in 2012. The presenter of the programme (Michael Mosley) then went on to write a best-selling book on the subject.

If you're in the UK, you can still watch the programme on iPlayer
