Tom Jones is known for hits such as It’s Not Unusual and Delilah. He is also known for his appearance as a judge on The Voice.
Tom explained more about the caveman diet, telling the presenter: “It tells you to get back to what we used to eat when we were hunters and gatherers.
“Eat anything that’s natural – meat, fish, veg.”
The singer went on: “The dietician asked, ‘how much do you drink?’ I told him I like a bottle of red wine with my dinner. ‘To yourself?’ he said.
“What I didn’t tell him was I’d started off with a martini, had a cognac and a bottle of champagne too.”
those hoping to lose weight should try and have a breakfast high in protein, Dr Michael Mosley told Express.co.uk.
He said: “It is well known that moderately increasing the amount of protein in your diet can help you to feel more satisfied after meals.
“What is less well known, though, is that the time of day that you eat protein also matters.”
