Kourtney Kardashian previously cut dairy and gluten out of her meals but now wants to "switch things up" and refamiliarise her digestive system with different foods as she had been experiencing pain when she indulged in a "treat" because her body was no longer used to foods such as pizza or ice cream.
She said: "Lately, I've been less strict about avoiding gluten and dairy. I noticed my tummy would hurt when I occasionally treated myself to ice cream or pizza, so I've switched things up. I'm trying to keep small amounts of both dairy and gluten in my system, so my body is used to it when I do have a little."
And the 39-year-old star finds her new regime much "better", especially when she is travelling with her three children, Mason, eight, Penelope, six, and three-year-old Reign, who she has with ex-boyfriend Scott Disick.
She continued in a post on her website: "I love trying local food and eating everything without rules -- especially when I'm travelling -- so this is working better.
"When the kids and I were on vacation in Italy this summer, they loved getting gelato every day -- and I always had a small scoop, too!
"When I'm on vacation, or if we go to Disneyland, that's the time to live life and I'll have whatever I want."
But Kourtney isn't relaxing her rules entirely and will still keep her house dairy and gluten free.
She said: "Everything in my pantry is still free of dairy and gluten, so when I'm at home, it's still how I eat.
"But when I go out, or have a craving, I'll have whatever I want. I try to do everything in moderation in my usual routine."
Kourtney's bigger change comes after she previously confessed to the occasional "cheat" day.
She said: "When I'm travelling (and sometimes on the weekend), I'll cheat — I'm a little more lenient now than I was when I first started this whole thing.
"But when I'm home and in my day-to-day routine. I try to exercise five to six times a week and eat healthy every day."
