One Direction star Harry Styles has put his sweet tooth on hold in an effort to tone up his body.

The British boyband are regularly on tour so fitness is paramount if the lads want to put on a good show for their fans.

The 'Kiss You' stars' fitness trainer Mark Jarvis has told the Daily Star that Styles has stopped eating overly sweet foods to try to improve his diet and body. He said:

"He is keen to ditch all the cakes and sweets. His favourite is black forest gateau."

Jarvis added: "The lads want to get defined beach bodies. Lots of protein is the best way for them to get in shape and build up muscle. Harry has heard about this new healthy ice cream and is really fascinated by it. He has requested boxes of it to be flown over as he has a real sweet tooth."
