Michael Douglas has been put on a weight-gain diet.

The 'Wall Street: Money Never Sleeps' actor is suffering from throat cancer and now weighs less than 140 pounds following chemotherapy and radiotherapy treatment for his condition.

He has consequently been placed on a rich diet of creamy pasta, organic liver and liquidised chicken to help him get back to a healthier size.

A source told the Daily Mirror newspaper: "He needs to bulk up. He's so fragile that doctors are worried he won't be strong enough to recover from treatment which has left him weak.

"The liver and fats help alkalise the body while the chicken is nourishing. It's all easy to swallow."

The 66-year-old actor - who is married to actress Catherine Zeta-Jones - recently revealed he cannot wait to enjoy a glass of wine when he has beaten the disease.

Michael - who has already started the weight-gain diet - said: "I've always been a positive person and I will kick this thing. But on the other hand the processes that they are using to eliminate it will take their toll.

"A lot of my energy has gone and I have increased soreness in my mouth. But overall I feel good. And I'm looking forward to enjoying a good glass of wine when I get my tasted buds back again."
