Eating healthy has transformed the life of Nicole Polizzi, the former party girl best known as “Snooki" from MTV's “Jersey Shore.” After she fell in love with the man who is now her husband and became pregnant with their first child, Polizzi adopted a healthier lifestyle: She ditched fist pumping and drinking for exercising and juicing.

Junk food made Polizzi stupid on “Jersey Shore,” she told Yahoo Beauty editor-in-chief Bobbi Brown Thursday. “The more crap I ate, the stupider I got, as seen on Seasons 1 through 5 of ‘Jersey Shore ,’” the TV personality said. “Although I was consuming thousands of calories a day during the party years, I was actually starving myself of healthy food.”

Making healthier choices cleared her head. "When I stopped drinking and started eating lots of greens, whole grains and lean meats, it was like my brain woke up from a five-year coma," she said. "My life turned around, and things clicked into place in my relationship and my career. What goes into your body comes out in your life. If you want success, love and the strength to cope with anything life throws at you, feed your body the healthy food it needs."

Polizzi is arguably the most successful cast member from “Jersey Shore.” She’s a New York Times best-selling author and has created a beauty and fashion empire. She also has her own podcast, “Naturally Nicole,” where she shows she hasn’t lost the honesty that made thousands of fans fall in love with her in the first place.

The former reality star is currently promoting her new book, “Strong is the New Sexy.” In the book, Polizzi “shares with her fans how she’s transformed both her body and mindset -- and shows how they can do it too!”
