It's no secret that Kim Kardashian has been amping up her workouts and maintaining a super-strict diet—and she continues to use her Twitter feed to connect with fans while she's on a mission to slim down. 

The 33-year-old beauty took to the social media site on Wednesday to vent about her sweet tooth (she's previously confessed to her obsession with cookies and candy) and to inquire about the documentary Fed Up, which focuses on the causes of obesity in the U.S.

Last week, Kanye West's missus took to Twitter to let fans know she was taking a cue from her younger sister Khloé and has been hitting the gym hard. 

"ughhh my workouts this week were torture!  is killing me lol!" she wrote, calling out her celeb trainer Harley Pasternak. "I literally can't walk..thanks Harley." 

North West's mama is pretty disciplined when it comes to both her diet and exercise. She is often photographed heading to and from the gym and she previously shed an impressive 50 pounds of baby weight with help from the Atkins diet after giving birth to her daughter in June 2013.

At the beginning of August, the E! star went on a Twitter rant and expressed her frustrations over not being able to lose the last bit of baby weight. And mere weeks later, she'd already managed to lose a few pounds. 

"I did slim down," she confirmed to E! News at the MTV Video Music Awards. "When I was tweeting about it, that was the start, and I started that day. And I did really low carbs, and I got it together. I lost like 6 or 7 pounds and I feel good. I fit into my stuff the way I wanted to. It wasn't a whole lot that I wanted to slim down, I just noticed that I wasn't fully comfortable."
