The 5:2 diet is an increasingly popular diet plan with a flurry of newspaper articles and books being published on it in the run up to Christmas 2012 and in January 2013.

The diet first reached the mainstream via a BBC Horizon documentary called Eat, Fast and Live Longer, broadcast in August 2012.

The 5:2 diet is based on a principle known as intermittent fasting (IF) ? where you eat normally at certain times and then fast during other times.

The 5:2 diet is relatively straightforward ? you eat normally five days a week, and fast on the other two days. However, this isn?t the traditional concept of a ?fast? in religious terms (eating nothing all day), instead this fast is a form of extreme calorie restriction: dieters are advised by this plan to eat no more than 500 calories if you are a women, or 600 calories if you are a man, for two days a week.
