Kim Kardashian's special salad

Reality TV star Kim Kardashian West makes the same order at her favourite deli so often that she has her own button on the till.

"I was in Calabasas and I popped into Health Nut, the store where her family buy the salads they are always eating. I asked the guy at the counter for Kim's favourite salad. 'No problem' he said, putting my order into the till and taking my money," Author Sean Smith, who is writing a biography of the reality star, told heat magazine, reports femalefirst.co.uk.

"'What's in it?' I asked. 'No idea', he said, 'I just hit a button marked Kardashian,'" Smith added.

The 34-year-old has her favourite salad at the deli, she said that she and husband Kanye West have hired a nutritionist who changes their meal plan regularly.

"Kanye loves to eat really healthy and is always on different diets. He has a chef who comes in the morning and cooks breakfast for both of us and gets our meal plans together for the day. We just started seeing a nutritionist who changes our diet every 10 days," she said.

"I think after you have a baby you want everything to be as pure as possible. I want to set an example and to be natural and healthy. It's a decision Kanye and I made, to see a nutritionist together," Kim added.
