Matthew McConaughey’s drastic 30-pound weight loss has been heavily chronicled and now RadarOnline.com can reveal that his Dallas Buyer's Club costar, Jared Leto, is following in the method actor's emaciated footsteps.
The rocker unveiled his startlingly skinny look at the Gotham Independent Film Awards on Monday, sparking concern from both movie fans and health experts at his extreme transformation to play cross-dressing AIDS victim, Rayon, in the biopic.
"He does look like he's lost a lot weight. On a slight frame, as little as 10 pounds can really make a big difference," Jackie Keller, CEO of meal delivery service NutriFit, told RadarOnline.com in an exclusive interview.
"All that being said, as a slender man, Jared obviously doesn't need to lose weight except to play the role of a skinny, underfed guy with hollowed out checks and a long face.
"Jared can't be more than 120 pounds in theses photos," added nutritionist Majid Ali, who has not treated the star, told Radar. "To me he looks pretty gaunt like someone who has been, or is ill."
The 30 Seconds To Mars musician hasn't had a major movie role since he played John Lennon assassin, Mark David Chapman, in 2007's Chapter 27, when the 5'9" actor gained a whopping 67 pounds to mimic the killer's doughy physique.
At the time, Leto, 40, admitted that his obsession to envelop himself in the part had taken a toll on his health, telling the Los Angeles Times: "I'm not sure it was the wisest choice.
"A friend of mine was recently going to gain weight for a film, and I did my best to talk him out of it. Just because you can lose the weight doesn't mean the impact it had on you isn't there anymore." By the end of filming, the extra flab had taken such a toll that he could no longer walk to the set.
Five years later, the dedicated actor – who even waxed his facial hair and donned nail polish off-set to play the drag queen - has gone to equally dangerous lengths that could permanently damage his metabolism and digestive system in the future.
"All the stars of Dallas Buyer's Club are losing weight and again, while it is easier for a man to do this than a woman and most likely safer, it is still dangerous as their age due to issues with heart attacks, dehydration and sexual dysfunction," warned nutritional expert Dr. Fred Pescatore.
