Karl Lagerfeld hates exercising and finds it much easier to stay slim by cutting all fat out of his diet.
The fashion designer lost 90lbs ten years ago after switching to a strict diet of steamed vegetables and Diet Coke and said he wouldn't go back.
He said: "No cheese, no butter, nothing. But I'm perfectly happy with that. My chefs are great so it tastes beautiful.
"People who are obsessed with exercise, they are brainwashed. It's a bore. People exercise because they eat a lot. I don't eat that much so I don't have a lot to get rid of."
And when it comes to relaxing, Karl doesn't like to travel, saying it's a "nightmare".
He added in an interview with British In Style magazine: "It's not an adventure anymore. Everything is made to the taste of the tourist.
"I am not a holiday person. I prepare the collections; I read. I am not on a boat in the sun. It's my victims [his staff] who are on holidays, not me."
Karl also revealed he has "no times" for social media, despite owning four iPhones and his cat Choupette having her own iPad.
