Fasting is as old the hills of ancient Greece. Mention just about any Greek sage you can think of: Plato, Aristotle, Plutarch, not forgetting the father of modern medicine, Hippocrates and maths whizzkid Pythagoras. All were dedicated followers of fasting. 

Fasting is not for the faint-hearted. In its classical form of no food or drink – except for water – for an extended period, it takes  commitment and discipline. (I’ve only ever managed to last eight days on water only.)

Below, a University College London neuroscientist looks at the power of intermittent fasting. Dr Nick Lesica says it’s ‘all the rage’ right now. Don’t even think of dismissing it as a fad. Research suggests it can give you the benefits of fasting without really fasting.
