Los Angeles: Scottish actor Gerard Butler has laughed off concerns over his recent weight loss, saying he has been on a strict diet in preparation to play a surfer in a new movie.

The '300' star, who showed off a robust physique in his latest movies, appeared much leaner at the Toronto film fest, sparking concern among his fans.
     
But the 41-year-old actor is adamant there is no need to worry about his health, putting his new lean look down to a vigorous pre-filming routine, reported in website.
     
"If I wear a long shirt, everyone says 'Oh my God, he lost so much weight!' But this is how I look. I just used to be a lot bigger. But now I'm surfing. I'm doing a surf movie so I have to slim down. I don't know... maybe I'm sick or something!
     
"It's just doing a lot of cardio and extremely watching what I eat. I stopped lifting big weights and I'm doing yoga. It's not hard to be in shape... it's hard to be in really good shape. I generally train for a role and give everything to that, and then you stop and then you do it again," said Butler.
