Jena Desiderio showed what happened when she initially lost weight over the course of a year — she dropped pounds and inches, but, as she said in her Instagram caption, she lost her butt. "Even though I was super skinny in the middle picture, I lost my butt!" she wrote in her caption. "I ALWAYS had a butt, my boobs were gone, and I didn't fill out clothes the way I wanted to." Now, she's working on toning and defining her body, and the results speak for themselves!
