The Fast Diet - Pros and ConsThe Fast Diet

The 5:2 diet or The Fast Diet has been on most dieters' lips in the past year. The Fast Diet book, written by Dr Michael Mosley and Mimi Spencer, reportedly became Amazon's best selling book last year, being allegedly used by various celebs from Jennifer Lopez and Beyonce to Benedict Cumberbatch.

How does the 5:2 diet work?

The idea behind the new 5/2 diet is simple: eating a healthy diet and consuming a regular number of calories for five days and fasting for two days. During the fasting days, women are allowed to consume 500 calories only while the limit for men is 600 calories. The two days of fasting don't have to be consecutive and don't have to be the same ones every week, so dieters can choose the days that work best for them and that don't interfere too much with their schedule.
