Kardashian, who has lost more than 50 pounds since giving birth to daughter North last June, retweeted the post with her own personal message.

"Preach! LOL, thank you!" the Keeping Up With the Kardashians star said. "It sucks when people make up surgery or Photoshop lies when I am so disciplined & work so hard! Just trying to motivate others & show anyone struggling with weight they can totally achieve whatever they want if they are dedicated!"

The first-time mother is indeed dedicated. "She wakes up and does more than 100 squats every single morning," a source told Us Weekly in December of her diet and fitness efforts. "Even now, when she can wear the things she did before her pregnancy, she still wants to tone her body."
