Although Kendall, 20, is a supermodel, Khloe, 32, admitted she is surprisingly eager to eat junk fund and if Khloe needs a break from her healthy diet, she will turn to Kendall.

She wrote on her app: "People always find it funny that Kenny 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!"

However, Khloe is less likely to follow her older sister Kim Kardashian West's eating plan, as the mother-of-two is currently on the Atkins diet.

She explained: "I wouldn't last a day on Kim's new diet. I like sweets too much and also don't eat red meat or dairy so I'm saying hell no to this one!"

Meanwhile, Khloe has lost an impressive 40lbs after undergoing a strict diet and exercise regime and admitted she was shocked recently when people recently started saying she had taken it too far.

Writing on her Twitter account, she said: "I need to remember the date today!! Never would I have ever thought I would be in the media for being "too skinny". What on earth?!?!

"First I'm too fat and now I'm too skinny. I love this game!!"

The beauty previously claimed many stylists did not want to work with her before she lost weight.

She explained: "I definitely think the fashion industry, and people in general, look at me more now that I've lost weight. Even on shoots, I would never have options for clothing. There would always be this attention on my sisters Kourtney and Kim, but I was too much work for [stylists] or they had nothing in my size. I wasn't even that crazy big!"

However, Khloe's longtime stylist Monica Rose always managed to find beautiful clothes for her to wear and, as a result, she is now the main person that Khloe turns to for photoshoots and public appearances.

She said: "At my fattest, Monica would always come with racks of clothes and make me feel special. She never told me, 'Oh, they don't have that in your size.' Other people actually said, 'I just can't work with you'- because I was too big. That always hurt my feelings, of course."
