Los Angeles: Actor Matthew McConaughey has lost about 18 kg for a movie role, and despite the drastic weightloss he says he is "as healthy as can be".

He has lost pounds to play a skeletal AIDS victim in his latest movie "The Dallas Buyer`s Club", and his lean frame is giving fans some cause for concern.

However, McConaughey insists his extreme dieting isn`t taking a toll on his health as he is relying on a healthy diet of fish to keep his energy levels up, reports

"I feel fine. I really do. I`m eating fresh fish. I`m just eating small amounts. I`m not being starved. If anything, it`s as much a spiritual journey as it is physical. I have body soreness. (But) I`m as healthy as can be. My blood pressure, everything`s fine," he told

The "Magic Mike" star had earlier said he will indulge in a greasy cheeseburger once filming on the drama ends, but he now accepts he won`t be able to do so straight away, especially after dieting so much.

"You can`t just start eating cheeseburgers and ice cream. Your body will go into shock," he said.
