Is this timed eating technique worth the hype?

Listen | 23:47

Health and family editor Damian Cullen had already ticked off a long list of diets before he hit on intermittent fasting and three years later, and 16kg lighter, he has stuck to the plan. He eats in an eight-hour window.

At the more extreme end of intermittent fasting, British prime minister Rishi Sunak follows the so called “monk fast” of eating nothing for a 36-year period every week.

As a way of losing weight, timed eating is probably the weight loss method of the moment; it follows a long list of diets, some of which became wildly popular for a time and then slid off the menu.

Cullen explains how it works for him, while dietician Sarah Keogh gives the expert view. Presented by Bernice Harrison. Produced by Suzanne Brennan
