For breakfast, Kardashian says she is allowed to eat “minimal amounts of fruit,” so she usually opts for her go-to avocado smoothie (which she also uses on her hair, FYI). For lunch and dinner, she sticks to proteins like fish and chicken and maybe some cauliflower rice or broccoli. Following dinner, she is not allowed to eat breakfast for 14 to 16 hours.
Oh yeah, and one day per week, she does a 24-hour fast during which she only drinks water and bone broth. “On fasting days, I try to stay busy and, if I’m home, I’ll avoid going into the kitchen,” she says.
Finally, there is no snacking permitted, other than the occasional handful of almonds for Kardashian.
“I’m not going to sugarcoat it, this detox is difficult,” she says, adding that her goal has been to stay on the diet for 3 months. Of course, she does make some healthy exceptions. “I also know that I need to enjoy my life, so I break the rules when I go on vacation or if there’s a special occasion.”
