Stallone to reveal dietary secrets

Sylvester Stallone is writing a book about his dietary habits and fitness regime because he's sick of being asked how he looks so good at 58.

The Rocky star hopes to explode myths about diets in the new tome, which he hopes to release this summer, and insists the secret to his success has always been about moderation.

He says: "I try to figure out what has worked over the years and stick to it. I'll overeat on a certain day and the next day I'll just cut back... after a while it becomes second nature.

"Diets don't work. It's taking whatever you do and just moderating it... I'm just gonna lay it out for people."

And Stallone admits his dietary tips have already paid off on pal and former boxing champ Sugar Ray Leonard, who had let himself go after years of fighting fit.

He adds: "When I met Ray he was like a big, dumpy guy. He was pathetic... Now look at him."

It's a busy year for the movie star - he's also launching a new US boxing reality show, The Contender, later this month and he has a new dietary supplement range.

The actor is also the editor-in-chief on new mature men's magazine Sly.
