Khloe Kardashian
Khloe Kardashian's weight has fluctuated a lot over the years, but after having a child, the show's host Revenge Body wrote in a report to HollywoodLife: “I just wanted to get back to my routine before I got pregnant, where I worked out five to six times a week.” Khloe Kardashian lost 15 pounds as soon as she got back into action, with the help of breastfeeding and a healthy diet.
