Fiber is essential for healthy digestion, even on keto. It helps regulate bowel movements, keeps you feeling full and satisfied, and can even help manage cholesterol and blood sugar levels.

4. What are some signs I might have a food intolerance? 

Common signs of food intolerance include bloating, gas, diarrhea, constipation, headaches, and skin rashes. If you experience these symptoms regularly, consider food sensitivity testing to identify potential triggers.
