Mum-of-two Amanda works hard to maintain her incredible figure – but she never denies herself a treat. "You have to enjoy life," she previously told the Daily Mail. "I had a friend once who didn't make it to her 50s and her biggest regret was that she spent her life on a diet. I think a little bit of everything is fine.
"Life's too short to do fat-free, sugar-free, alcohol-free. I don't believe in half-fat anything, I have full-fat yoghurt, butter and cheese. And I splurge on the weekends. I love wine."
Amanda looks better than ever
There is one food group that Amanda avoids though: meat. According to the book Amanda Holden, written by Jim Maloney, Amanda "decided to become vegetarian after being influenced by famous veggie Morrisey, lead singer with the Smiths", but continues to eat fish, making her a pescatarian.
