Khloe Kardashian doesn't think she'd "last a day" on Kim Kardashian West's diet.
The 'Keeping Up With The Kardashians' star is impressed with her sibling's commitment to keeping healthy but admits the Atkins diet isn't for her.
She shared: "We all have such different eating habits that sometimes when we're trying to choose a restaurant I wonder if we're even related. LOL! ...
"I wouldn't last a day on Kim's new diet. It involves cutting out all sugar and carbs but it allows meat and dairy. I like sweets too much and also don't eat red meat or dairy, so I'm saying hell no to this one!"
And the 32-year-old television personality loves her step-siblings Kendall and Kylie Jenner's attitude to food.
She added: "People always find it funny that Kendall is on the anti-model diet. She loves burgers and pizza and goes to In-N-Out all the time. Kendall is my go-to girl on cheat day!
"Kylie eats like a typical teenager but she's also super aware of what she puts in her body when it comes to fresh and organic foods. It's all about that moderation, too!"
However, Khloe believes her eldest sister Kourtney has the strictest approach to dieting and joked she considers "locking her pantry" before the 37-year-old star comes to visit.
Writing in a post on her official website, she explained: "Kourt only eats organic food and has pretty much convinced herself that she is allergic to dairy and gluten too. She's by far the most cray about her diet! I always feel like I need to lock my pantry before she comes over so she doesn't yell at me for what's in it, LOL."
