After weeks of hard work, Kim Kardashian is starting to see some changes in her post-baby body, thanks to the Atkins Diet and her own determination.
"Wanting more things to start fitting - 42 lbs. down and 28 to go!" she wrote in a blog post on March 21, adding, "wearing my old workout clothes! They fit again."
The reality star and mother of two has been trying to scrap the extra pounds she put on while pregnant with her son, Saint, plus a few more she's been carrying around since the birth of her daughter, North.
"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," she wrote on social media back in January. "This is going to be soooo f------ hard but I can do it and I can't wait to share it all with you!#BeastMode #WhosWithMe ?!?!?!"
Having successfully lost weight with Atkins in 2013 following North's birth, Kim returned to the diet this year.
She's reportedly using the Atkins 40 program, which allows more carbs than the traditional version of Atkins, ensuring that she doesn't run out of energy due to breastfeeding while dieting.
"We can pace the weight loss at 2 lbs. a week, so that it won't affect her breast milk and she gets adequate protein from chicken, fish and some meat," her nutritionist, Colette Heimowitz, told "Extra" in January.
"Kim is staying on track with her weight loss progress and taking it day by day," a source recently told E! News. "She is very busy with Saint and North [West] in between of taking care of herself and being a wife. Running around with the kids definitely helps with shedding some weight, and she has been working out and eating healthy."
While Kim remains focused on tuning her body, she's also been making time for her husband, Kanye West, who recently returned home from Paris Fashion Week.
The couple stepped out for a Justin Bieber concert on Monday night, joining a star-studded guest list that included the Biebs' rumored friend with benefits, Kourtney Kardashian, rapper Big Sean, and Jennifer Lopez.
