Matthew McConaughey's Weight Loss Continues As Actor Leaves The Gym Looking Gaunt (PHOTOS)

It's no secret that Matthew McConaughey has been shedding pounds for his new role in "The Dallas Buyer's Club," but his weight loss is officially messing with our minds.

The normally buff actor, 42, is scary skinny as he prepares to lose 30 pounds to play HIV patient, Ron Woodroof, in the movie set to hit theaters next year. He was spotted looking frail while leaving a gym in Austin, Tex., on October 12, covering up in loose sweats.

Im playing a guy who was sick and would have loved to have been healthier but wasnt. For me, its more of a mental thing than a physical thing, McConaughey shared with Us Weekly . Ill get down to the weight I need to get to. Im on my way, and its what I need to do for the job.

Last week, McConaughey shocked onlookers when he stepped out with his family looking frail as he strolled arm-in-arm with his mother . His wife, Camila Alves, is expecting the couple's third child later this year.
