And welcome back to "Gma." Nice crowd here on a Wednesday morning. That's right and we have a lot to get to this morning including Khloe Kardashian who is turning heads this morning looking great on the cover of "Women's health" magazine revealing an astounding transformation. I love this. She calls it her revenge body. And Paula is here to tell us about it. She looks healthy and happy. The youngest of the Kardashian sisters and says she's not known for self-control making her 35-pound weight loss all the more impressive. Take a look. I work out with a vengeance. I have a purpose there and love to sweat. If you've been keeping up with the considers lately you notice Khloe go from this to this in what seemed overnight. Now in the new issue of "Women's health" magazine, the 31-year-old reality star says it's no accident she looks better. Her transformation has been three years in the making. Telling the magazine "Because I have no self-control and I don't really care to have it, I have to work harder." This woman has put in so much sweat she really earns that body. Reporter: She says her weight loss was the result of a full lifestyle change. Working out every day, cutting out soda and constantly changing her workout plan. It's not over until the fat lady sings. Khloe is singing. Reporter: She tells the magazine losing the pounds was also a way to silence her critic. It's a revenge body, she says for all my critics who called me the fat one for my entire existence. The driving force behind it was something we can relate to, heartbreak. She was going through a breakup with Lamar and she really just needed a release so she would go to the gym and work out. Reporter: So how can you get her banging body results? You will be able to stay like this -- Reporter: Los Angeles exercise physiologist Joshua Naderman recommends these three. The hollow hold lets you focus on your core and the goblet squat les you get everything moving down a little, hold and up. The deadlift lets you target in on the problem squat of the gluts and bring your foot up off the ground and come down. Reporter: Keeping up with the kardashians never looked so good. We would attempt those but we all have dresses and skirts on so not for TV. Taking it slow is the right way to do it. More chances of keeping it off. She did it over three years. Not everybody has the time and resources but if you put in some hard work every day. Every day, no soda. Looking good, Khloe.
