Kim Kardashian West has already shed 17 pounds since giving birth to her son Saint a little over a week ago.
The 35-year-old mother of two revealed her weight loss during a live stream on her website Monday.
"Going live! Christmas decorating & Cooking with Caitlyn on my app now," Kardashian West tweeted, inviting fans to join her while she prepared Chicago deep-dish pizza for Caitlyn Jenner.
Passing on the pizza herself, Kardashian West shared that she gained 60 pounds while pregnant with Saint and weighed 190 pounds by the end of her third trimester. "I almost died," she said.
She also revealed that her goal was to lose 70 pounds to reach her ideal weight of 120 -- four pounds less than she was when she got married. Meanwhile, she's already down 17 pounds, with the help of breastfeeding and healthy eating.
"You are looking much better," Jenner told her, to which Kardashian West responded, "I am feeling much better."
While remaining off camera during the live-stream, Kardashian West explained that she would "reveal" herself soon.
"It's not even about how I look...no makeup and sweats," the brunette beauty said. "I know I have been on social media a little bit, but I wanted this time to not have to care or post something about myself."
Kardashian West and husband Kanye West welcomed their second child on Dec. 5, a few weeks before his due date.
She confessed to Jenner that her recovery this time is harder than with daughter North West, 2.
"This feels like a really hard recovery but we will get through it," she said. "Everyone does it."
