The Levi Johnston Diet: Moose, Publicity

Levi Johnston has been working out like a madman to prepare for his Playgirl photo shoot. He's also looking to gobble up massive amounts of publicity and attention high-protein moose meat whenever he can go hunting.

The 19-year-old baby daddy of Bristol Palin definitely didn't shoot blanks when he knocked her up last year, so you best believe he uses live ammo, if you follow.

"Moose meat is very good for you, high in protein and very lean," his trainer, Marvin Jones, told People magazine. "[Levi] is an avid hunter, so he has his own."

He's adopted a 3,500-calorie low-carb diet as part of a grueling regimen to ready him for next month's highly-anticipated Levi Johnston nude photo shoot.

Johnston works out three hours a day, six days a week, followed by cardio training and then rest in the sauna. It's a tough life, but someone's gotta do it.

Whether he's hunting moose or sleeping with Sarah Palin's daughter, Levi Johnston does not mess around. The safety is definitely not on, if you know what we mean.

"I'm not trying to give him that body builder look. He's going to be more toned and defined," says Jones. "I'd like to see him with rounder and more muscular shoulders, with a fuller chest. We're going to firm his abs up, give him a smaller waist."

Levi has also been milking his 15 minutes of fame to death paying bills by busting a nut in an ad for Wonderful Pistachios. Is this a great country, or what?

He may not have ever really been engaged to Bristol Palin, but Johnston is wholly committed to the training sessions, according to his fitness coordinator.

"I know this is something he wants to do and we're having fun training," says Jones. "We're very much looking forward to revealing all his hard work!"
