What Ever Happened to Jackie Warner?

Looking back at our shows, we often wonder about the people who've left. Where did they go when their moment in the Bravo spotlight was over? What are they up to now? Each week, we'll be looking into the lives of one of these familiar faces. Today, it's Jackie Warner from Work Out and Thintervention.

Hard-bodied gym owner and personal trainer-to-the-stars Jackie Warner chronicled her tough-as-nails approach to fitness as well as her drama-filled relationships with women on Work Out for three seasons. But after starring on the show from 2006 to 2008, she left amid controversy she'd created after she made unkind comments about a fitness model and breast cancer survivor who was working out in her gym.

Work Out continued on for one more season without Jackie, and two years later, she was back on Bravo starring on another body-conscious show: Thintervention. But leading up to and during its single-season run, Jackie was growing increasingly unhappy with her life.

She sold her Beverly Hills gym, Sky Sports and Spa, and decided to swear off reality TV as she "fell into crisis," she writes on her new website. "To be honest, I felt a bit lost and started partying a lot. It felt like I was taking a few steps backward in life and I started making bad decisions."

"I looked in the mirror one morning and realized that I did not like the person that I had become," she adds. "I could no longer hide the fact that MY decisions were causing me unhappiness."

Jackie realized she needed to accept responsibility for her actions and devise a plan to pull herself out of her misery. "I quit drinking for a year and I quit dating for a year," she continues, adding that she prayed for guidance every morning and night and cut "almost everyone" out of her life including friends, business partners, managers, lawyers. She also started writing poetry, painting and even making music (she released Valkyrie, a five-song EP of dance music, in December 2014).

Slowly, it worked. "My new mantra is 'when in doubt, go workout,'" she writes. "When I was super lonely, I went to the gym. When I wanted to drink, I went to the gym." She also published two fitness and diet books—2010's This Is Why You're Fat (And How to Get Thin Forever) and 2012's 10 Pounds in 10 Days: The Secret Celebrity Program for Losing Weight Fast—which both became New York Times best sellers.

In early 2015, 46-year-old Jackie opened up on her blog about her desire to become a mom. Although she no longer speaks openly about her love life, she has revealed she's been undergoing fertility treatments for the last two years in hopes of getting pregnant. When the hormones caused her to pack on 20 lbs. and upped her weight to 150 lbs., it inspired her to develop a new workout that's helped her shave 10 lbs. off her frame, leaving her with a remarkable 7 percent body fat.

In January, tragedy struck: Jackie's Work Out costar, fitness model and trainer Greg Plitt, was struck and killed by a train in January 2015, and she was devastated. "Greg was a living example of health & strength. He lives on in our hearts & minds," she tweeted in tribute. "He was beautiful on the inside & out."

Now, Jackie is preparing to release her third book: This Is Why You're Sick and Tired (And How to Look and Feel Amazing) comes out on April 28, 2015. She has high hopes for its success. "Just like me, you can reinvent yourself," she writes on her website, "and learn to fall deeply in love with yourself."
