“Jersey Shore’s” Sammi “Sweetheart” Giancola is revealing how she was able to shed 15 pounds while still managing to party it up while filming in Miami for season 2 of the hit MTV reality series.

Sammi told Life & Style, “I just changed my diet, and the next thing you know the pounds just came off.”

The reality star dropped in for a photo shoot exclusively for Life & Style to show off her new body, minus a whopping 15 pounds. The first thing she changed was cutting out the carbs. She told the mag, “I miss it like crazy, but I don’t eat pasta anymore,” she tells Life & Style. “I eat my vegetables and try to stay healthy.”

Her diet wasn’t the only thing to change, Sammi also took on an intensive cardio routine, saying, “I do soccer drills – I jog a lap, then sprint, jog the rest of the way, then sprint again.”
