letoskinny460.jpg Matthew McConaughey isn't the only Hollywood hunk who is good at starving!

Jared Leto dropped a dramatic amount of weight to play a transexual in the upcoming film "Dallas Buyer's Club," and now he's showing off his emaciated body by posing for photographer pal Terry Richardson.

The actor is wasting away, and it's all thanks to fasting! The My So Called Life star revealed he hasn't eaten a thing in almost a month!

We can't believe he has the energy to do anything with no food for fuel!

To complete his transformation, the 40-year-old shaved his eyebrows off, presumably to draw ones on and appear more feminine.
