LOS ANGELES: Leonardo DiCaprio has taken on a strict diet and exercise regime to fight the flab before filming the gruelling action scenes in his latest movie Inception, reports thesun.co.uk. “Leo needs to shed at least 30 pounds. There’s an action scene in which he needs to appear emaciated,” a source said.

“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,” the source added. Inception is a psychological thriller about an office worker involved in a blackmail plot.
