Bollywood's King Khan Shah Rukh, who is working very hard to make his upcoming sci-fi movie Ra.One, a big hit, has become very weak these days. And the reason is not just long schedule but the super hero costume that he wears during the shots.

SRK was seen in six packs in the 'Dard-e-Disco' number of 2007 movie Om Shanti Om. But the superhero suit has lost his super-physique now. Actually, the actor cannot eat anything when he is wearing the suit and he needs to keep it on his body for at least eight to nine hours every day. As a result, SRK was missing his regular proper diet.

The suit was ordered from the US and it's made from materials like Styrofoam and rubber. The suit carries lots of wires inside. The slimming effect of the materials in the suit continues to exist even after removing it from the body of wearer. However, the forty days shooting schedule with the costume is over now.

It is reported that Gauri Khan is now feeding her hubby a lot of rice and chicken to get back his weight. SRK quipped that his children Aryan and Suhana were also turning him into a ninety pound pushover in the house so he will gain some weight very soon.

In fact, Amitabh Bachchan also showed his concern over Shah Rukh's health while posting on his Twitter page. He said that SRK should stop wearing that superhero jacket for some days and take in a healthy diet.

Hope this hard work and weight-loss gain Shah Rukh some success through this mega budget movie!
