Your gut health is the foundation for the proper functioning of your body because it supports your immunity, heart and brain health. It breaks down the food that you eat, and helps the muscles absorb the nutrients. The gut is the reason your body is free of toxins and you can maintain a stable moo, more or less. But if that is compromised, then it will increase your chances of getting diabetes and becoming obese.
So for that, you need to eat foods that are rich in probiotics to help preserve good gut health. Now keep in mind, some of them can hinder your progress in keto, so check the carb content before ingesting. You can have kimchi, pickles, sauerkraut and of course bone broth, which is the perfect companion to your keto diet.
