"I gained 60lbs during my pregnancy but have been an extra 10 lbs up for the last few years so it's time to really get to my goal" the mom of two explained on Twitter.

Kim previously revealed that she weighed 130 pounds at the start of her pregnancy and 190 towards the end. To lose the remaining 40 pounds, Kim is teaming up with Atkins. It's the same diet she used after giving birth to North West in 2013.

"Because it works for me!" she explained. "So much variety on #Atkins40 and Harvest Trail Bars = YUM"

Kim says she will share her workouts and diet plan on her app. "This is going to be soooo f**king hard," she concluded. "But I can do it and I can't wait to share it all with you! #BeastMode #WhosWithMe ?!?!?!"

"As much as I really hate the whole feeling of being pregnant, I enjoy the challenge of getting my body back after it's all over," she told fans. "I feel so accomplished when I'm back to where I want to be."
