Fasting isn't a new concept. Intermittent fasting to lose weight - and improve your health - is though.
The Alternate Day Fasting Diet was one of the first plans that centred on this new approach to weight loss.
The Fast Diet, or
5:2 Diet, is slightly different.
Instead of fasting every other day, authors Dr Michael Mosley and food journalist, Mimi Spencer advocate cutting your calories (500kcal for women and 600kcal for men) just two days a week then eating well for the other five. They say it's just as effective but much easier to stick to.
