Kim Kardashian just revealed she gained a whopping 60 lbs while pregnant with baby Saint. But of course one woman's pregnancy pounds is Kimmy K's cash cow, the 35-year-old announced yesterday that she would be trying to shed the pounds with the Atkins diet (aka huge endorsement deal).

The mother of two wrote, "This is going to be soooo f***ing hard but I can do it and I can't wait to share it all with you #BeastMode #WhosWithMe?!?!?!"

Kim also wrote, "I'm so excited! I'm 30lbs down today but 40 to go! I'm so focused. I will show u guys my workouts on my app & share my Atkins plan too!"

The reality star says she's on an eating regime with Atkins Insider, talking about how much she loves the brand's harvest bars on her Twitter feed.

After she gave birth to daughter North, Kim followed the Atkins diet to lose weight. The diet follows a low carbohydrate program and limits the intake of sugar and carbs.
