For those following a ketogenic diet, the question of whether tomatoes are keto-friendly is a common concern. While many fruits are typically avoided on keto due to their high sugar content, tomatoes occupy a unique position that deserves closer examination.
Understanding how tomatoes fit into a ketogenic lifestyle requires looking at their nutritional profile, carb content, and the various ways they can be incorporated while maintaining ketosis. Let's explore everything you need to know about enjoying tomatoes on a keto diet.
