Paul Burrell lost 22lbs on 'I'm A Celebrity... South Africa'.
The 64-year-old former royal butler admitted he hadn't been "as hungry as that in all my life" when he was taking part in the ITV1 show, and he was even dreaming about gorging on lovely food in the camp.
He said: "I’ve never been as hungry as that in all my life. I lost 22 pounds.
"I just thought, don’t complain. I mean, at points I think we were all dreaming about food. We’d all make it tougher on ourselves by thinking about food all the time.
"People at home don’t realise how hungry you actually are."
Paul admitted the lack of food made him lethargic on the show.
He said: "You get tired, lethargic. You want to lie on your bunk.
"You’ve just got to keep going for the good of the camp. You have to win challenges and trials or nobody eats.
"The best meal in camp Fatima cooked – it was Barracuda, leeks and fried potatoes.
"That lifts your morale when you see a delicious meal coming towards you. It doesn’t lift you for a long time, but it does lift you up. You just get on with it, stop moaning and get on with it."
Paul exited the show on Thursday night's episode (11.05.23) alongside Carol Vorderman, just a day shy of Friday night's finale (12.05.23), but he made "memories of a lifetime" on the series.
He said: "It was a rollercoaster of a ride at times and there were ups and downs of course.
"But at the end of the day, looking back on it, we had fun and made memories of a lifetime. I know it’s a cliché, campmates always say ‘I made friends of a lifetime on this show’.
"I didn’t the first time round. I didn’t. But this time was totally different. We bonded as a big family."
The 'I'm A Celebrity... South Africa' final is at 9pm on Friday on ITV1 and ITVX, and on Virgin Media One and Virgin Media Player in Ireland.
