The heartthrob actor has embarked on a major crash diet in the hopes of losing weight before the end of the year - and he's not enjoying it one bit.

"Leo needs to shed at least 30lbs," says a set source on Inception, the hotly anticipated action flick written by Batman director Christopher Nolan.

"He's gained weight recently and looks almost a bit flabby, which isn't good, especially as the camera adds pounds.

"There's an action scene coming up at the end of the year in which he needs to appear emaciated, so the pressure is on.

"Leo isn't the kind of guy who can just lose a radical amount of weight though - he gets very nervous about it.

"He's following a strict diet and is embarking on a rigorous workout regime.

He hopes to lose the weight through the old fashioned way of cutting back on calories and upping his exercise.

"Leo's a pretty determined kind of guy, when he sets his mind to things he always achieves them. Though this is going to be hard for him, you can guarantee he'll succeed."
