What does science say about intermittent fasting? | Gin Stephens and Professor Tim Spector

It seems like every day, someone new mentions intermittent fasting. But what is it, exactly?

There are myriad options — from the 5:2 diet, with two days of extreme calorie restriction each week, to the warrior diet, which involves eating only raw fruit during the day and a mammoth feast at night.

Whatever the approach, intermittent fasting involves restricting the window of time when you eat.

Supporters evangelise the benefits, promising weight loss, disease prevention, and even life extension.

Currently, the scientific evidence is unclear, but it's an exciting area that may be full of potential.

In today’s episode, Jonathan speaks with Gin Stephens, who has had a powerful experience of intermittent fasting transforming her health and weight. He also talks to Tim Spector, who will share what science can tell us about intermittent fasting today — and, interestingly, how much it can’t, yet. Plus, an exciting announcement about how this is set to change.
