Hollywood actor Jake Gyllenhaal lost 15lbs (7kg) for his current role in boxing movie Southpaw. His grueling training schedule saw him work out for six hours everyday for six months to achieve the idea weight of 175lbs.
Last year, he also dropped 30lbs to play his Bafta-nominated role in Nightcrawler, where his character was of a gaunt paparazzo Lou Bloom. The actor said that he lose weight “with a watchful eye of expert.”
"When I did Nightcrawler I went to a doctor first," Gyllenhaal said.
"It wasn't like I was doing what Christian did in The Machinist, but I was very careful about it. It affects your body, but I try to be as safe as I can. Sometimes things get a little dangerous, but you always have to be mindful.
"There tends to be a narrative of actors taking risks that I think is dangerous to put out there, particularly as young actors thinking about [their] craft," he added.
"There's a fine line [about having a craft and a technique, but] you have to know that these things are done with preparation."
