Matthew McConaughey may look sickly thin right now, but the 42-year-old actor is far from having any health problems.

Even so, the Magic Mike star continues to shock us with his diminishing weight.

He was spotted earlier this week going to church in Austin, Texas, with his family. Wearing a blue cardigan, button-up shirt and a newsboy cap, his cheeks are sunken in, his muscular body is gone and he has a small mustache.

McConaughey has lost about 30 pounds to star in The Dallas Buyer’s Club, a real-life drama based on a Texas man (McConaughey) with AIDS in the 1980s who treated himself with alternative treatments he smuggled from Mexico into the United States.

A source tells us that reports he achieved the startling transformation through an all-liquid diet are false. “There are liquids, but there are also vitamins and small portions of protein throughout the day,” the source said.

Shooting begins next week in Shreveport, La. Scenes of McConaughey’s character dying will be shot first. The actor will slowly put back on the weight to shoot scenes that show his character in better health when he was initially diagnosed with HIV and AIDS.
