Oscar nominee Jonah Hill is shedding new light on his dramatic weight loss.

In a recent interview with People Magazine Hill said he starting working with a nutritionist who got him eating better.

He admits his secret weapon was not Brad Pitt, it was sushi and other japanese food.

He told People he wished there was some crazy thing that he did to drop the pounds like a pill or genie.

It was, in fact, the nutritionist telling him to change what he ate and his eating habits.

In an interview with ABC news earlier this week, the 28 year old actor said,  he not only wanted to get healthy, he also wanted to lose the weight to help him get more dramatic adult roles.

Hill is nominated for a best supporting actor oscar for his role in the baseball movie Moneyball.
