Snooki on Her Body: "What the Hell Happened?"

Snooki on Her Body: "What the Hell Happened?"

Jersey Shore guidette Nicole "Snooki" Polizzi doesn't like what she sees in the mirror.

"I used to be fit," she tells "Now I look at myself, and I'm like, What the hell happened?"

So the MTV reality star, 22, is now on Dr. Siegal's cookie diet.

On the diet, she eats only one meal a day (usually chicken) -- and six cookies, each of which suppresses hunger. The six cookies -- which contain beef and milk protein -- each contain about 11 grams of carbohydrates and 90 calories.

The biggest challenge so far? No binge drinking!

"If I go out I am going to have a drink, but I am not going to have 10 drinks like I usually would," she says.

The 4'9" star's ultimate goal: "I would like be back to 100 lbs; I'm 110 right now."
