Dramatic Photo of Jersey Shore Star Snooki’s Weight Loss Before and After

This is the Snooki we all love to hate from the 'Jersey Shore' days. You know, the days when "The Situation" called her a meatball.

Snooki has dropped major pounds. Considering she's only 4'9 and recently had a child, she looks like a completely different person.

After conquering an eating disorder, and then giving birth to a future fist pumper, Nicole "Snooki" Polizzi got right to the gym.

How did she drop 42 pounds in 6 months? She told Us Weekly:

You just need to get your ass to the gym and eat healthy!

Sure, easier said than done, but obviously it's worked for her. As far as nutrition, Snooki's been using a 1300-calories-per-day meal delivery service. To put that in perspective, one bag of cheese puffs can pack as much as 1269 calories.
