Martin Clunes lost three stone in around 90 days while following a diet that allows him to eat freely on most days.
The 64-year-old actor, known for ITV's Doc Martin and BBC's Men Behaving Badly, said he started the regime after gaining weight and experiencing tired knees.
The Diet Plan
The 5:2 diet involves eating normally for five days a week while restricting calorie intake on the other two days. Clunes later moved to a 6:1 approach, fasting for one day each week.
He said: "I eat anything I want on the other days."
Health Considerations
The British Heart Foundation notes that some people find the plan flexible, but it warns that fasting days can leave them feeling hungry, tired or irritable.
