Kim Kardashian let loose and allows Kourtney’s son Mason Dash to a sugar-loaded snack while babysitting him. The reality star posted a photo revealing her cheat day along with her 10-year-old nephew and what appears to be ice cream and junk food. “When I baby sit...” captioned Kim while enjoying her guilt-free snack. Though Kim and Mason appeared to be enjoying this moment, Kourtney has abided by specific diet rules that only allow her children to eat organic treats. Kourtney’s fans are aware of her strict high-fat, low-fat diet and she encourages the same behavior on her kids. But this time, Kim might have gone behind Kourtney’s back and break the rules.

As mentioned on Kourtney’s Poosh website, the mother-of-three started keto diet a couple of years ago for a metal detox. The doctor “tested my muscles and found that I had high levels of mercury and lead in my system. He let me know that one of the fastest ways to detox was to keep my body in a state of ketosis,” mentioned Kourtney. In addition to the keto diet, Kourtney also does intermittent fasting during the week with one day dedicated to a 24-hour fast. “For me, this meant not eating for 14 to 16 hours after dinner,” she added. So it seems counterproductive when Kim introduces a fatty treat into her snack time with Mason.

Previously, Kourtney has mentioned that her kids only have gluten-free, organic and dairy free snacks. The 41-year-old entrepreneur usually avoids processed foods, sugary foods, grains of starches like pasta, all fruits except berries, beans or legumes, roots vegetables such as potatoes, unhealthy fats, condiments, sauces and alcohol. Aside from all these foods, Kourtney also has to avoid certain ingredients in foods, “Once I found good ingredient swaps and started stocking my pantry and fridge with the best alternatives—like almond milk, tortillas made from sweet potatoes, gluten-free waffle ingredients for the kids, dairy-free shredded cheese, etc.—eating this way became easier and a lifestyle choice that works for me and my family,” she shared.

This restrictive eating plan has helped her maintain a healthy and toned body. In addition, she even packs tons of snacks when traveling with her family. “When we travel, we’ll pack a suitcase full of our pantry staples and also bring healthy snacks on the airplane.” This way she can avoid eating unhealthy food when on the road. Though this a very strict diet, this has definitely set her up for success.
