Usually, her diet consists of whole foods like avocado, oatmeal, fish, fruits and veggies and other whole grains.

Kourtney is a big proponent of exercise. "I think I take time for myself to work out every day, which I never did—especially having three young kids," she told E! News.

Over the years, Kourtney has been candid about the changes her body has gone through, especially when it comes to fertility and pregnancy. “So, obviously my body has changed but it was all of the hormones that the doctors put me on,” Kardashian said to her friends during season 2 of The Kardashians in October 2022. “I think eight months of IVF treatment has definitely taken a toll on my body mentally and physically. It has taken a lot to get me to a place of feeling really comfortable and happy with the changes.” She also discussed all the comments from fans and the many times it has been questioned whether or not she is pregnant. “Everyone always comments on every photo that I am pregnant. Obviously, we wish for that but if it’s in God’s plan then it is.”

Kourtney tries to remind the world that being skinny doesn’t make you happy. “When I was super skinny, it is a time when I was super anxious.

3. She Helped Make Intermittent Fasting Mainstram

Kardashian was one of the early celebrity supporters of intermittent fasting. "For me, this meant not eating for 14 to 16 hours after dinner. I wouldn't eat past 7 p.m. at night, and then I would wait to eat breakfast the next day until after my morning workout, which would be around 10:30 a.m. to 11 a.m,” she said about the routine she followed.

4. She Also Promoted Keto

“My body never looked better than when I did the keto diet two and half years ago, when I did it for two months,” Kourtney wrote on Poosh in June 2019. “In my experience, I’ve found the best method to train my body to curb sugar cravings, burn fat and kick-start weight loss is by sticking to a keto diet.”

5. She Loves Her “Thicker” Body

Kourtney’s ideal weight has changed over the years. "My weight — I used to go so much by weight — I used to be 95 pounds. Then 105 became my new normal weight. I am 115," she explained. "I am so into my thicker body. I looked up photos of my body when I was so skinny — it is cringey."
