Trainer Latreal Mitchell on working with Khloe Kardashian, and the one thing to cut out of your diet -- now

Some weight loss shows and programs out there promise a crazy fast transformation, or that you'll lose half your body weight, stat -- but that's not exactly realistic. We sat down with trainer Latreal Mitchell, who is joining the show Revenge Body with Khloe Kardashian to pick her brain about what a real healthy body transformation looks like -- and what it takes.

And of course, we had to ask about working with Khloe.

"It's one of those strange things!" Latreal said, "Because you meet Khloe and you don't know what to expect. There's so much media and hype around her family, but she is one of the sweetest, most compassionate, caring people -- she hugged and thanked me a million times. It's really great to see how passionate she is about this project."

And this show is different, in Latreal's opinion, because it shows a transformation that's healthy and attainable. And one that actually fits into the client's daily life.

"What I love about this 12 week journey is that first, the amount of weight she lost is a healthy amount. And she can continue on after the show is over, because she still has to go to work every day, and cook these meals, fit these workouts in ... it's really real."

Watching people transform their bodies and get on a healthier path to life is part of Latreal's everyday, so she knows exactly what meaningful changes we can make to get started. First? Get rid of sugar.

"Sugar is the devil!" She joked. "It's the cause of so much disease, and the body doesn't know what to do with it, so it stores it as fat."

There's so much sugar hidden in foods that if we're all a little more conscious of it, and trying to reduce how much we eat, it'll be the biggest step in a weight loss journey.

Latreal is also passionate about people living healthy lifestyles from the get-go -- she founded the Fitness Bunch Foundation about 10 years ago, a non-profit to fight childhood obesity. She goes to schools to speak with kids about health and nutrition, and has created fun workouts for kids. She calls it her baby -- a true passion project!
