Kim Kardashian

Time for a celebratory salad! Kim Kardashian — who gained 70 pounds while pregnant with her son, Saint — is back to her pre-baby weight just five months after giving birth, thanks to a very famous low-carb diet.

“Yaaaassssss!!! #Atkins,” Kardashian, 35, captioned a Friday, May 13, photo via Snapchat. In the picture, the Keeping Up With the Kardashians beauty stands on a scale, which shows that she currently weighs 135.8 pounds.

Kardashian and husband Kanye West welcomed their baby boy on December 5, 2015. Saint joined big sister North, 2.

“This time I think weight has come off quicker than last time because I kind of learned how to eat better,” the Selfish author told E! News in April. “Last time I worked out a little bit harder. This time I’m eating differently. I’m doing the Atkins diet, and I’m so militant about it that I just started working really hard and I think the mix of the two will really help this last 20 pounds fly off. I’m praying.”

She added: “It’s a challenge. It’s not easy at all. We just got back from our family vacation [in Vail, Colorado] and every day we were up early working out.”

Kardashian’s Atkins nutritionist, Colette Heimowitz, told Redbook magazine that she consumed 1,800 calories a day and lost about two pounds a week. The breastfeeding mom followed the Atkins 40 program, which allowed for more carbohydrates.
