Reality TV star Khloe Kardashian doesn’t think she would “last a day” on her sister and reality TV star Kim Kardashian’s diet.

Khloe is impressed with her sibling’s commitment to keeping healthy, but says such a diet is not meant for her, reports usmagazine.com.

“We all have such different eating habits that sometimes when we’re trying to choose a restaurant I wonder if we’re even related,” Khloe wrote on her official website.

“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,” she added.

The 32-year-old loves her step-siblings Kendall and Kylie Jenner’s attitude to food.

“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,” she said.

“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,” she added.
