After having three kids, Kourtney Kardashian is now in the best shape of her life, and she breaks it all down in her app. She has a post where she gives all the juicy details on how she practices a low-carb, high-fat diet. Although she never labeled herself as keto, her carb intake was low enough to transition her body into burning fat rather than sugar.
A typical breakfast for her is avocado pudding, and the rest of her meals include a main source of protein and lots of cooked veggies or a salad. She also tries to fast one day of the week, only consuming liquids like apple cider vinegar and bone broth.
