Giles Coren calorie restriction diet, fruitarian diet and paleo diet on Eat to Live Forever

Giles Coren tries out three diets – the calorie restriction diet, fruitarian diet and paleo diet – on Eat to Live Forever.

The food critic takes up the three extreme diet regimes in a bid to push the very limits of life expectancy.

Giles’s search to find a diet which might extend his life comes after his great-grandfather lived to the grand old age of 93. His grandfather passed away aged 76 and his father Alan died aged 69.
