Can you eat fish every day on keto?

Does Fish Break Ketosis?

Fish does not break ketosis. While fish is a high-protein food, ketosis is maintained through the body’s ability to burn fat rather than carbohydrates. Protein, including that found in fish, is metabolized in a way that supports ketosis rather than disrupting it.

Ketosis occurs when the body shifts its primary energy source to fat, a natural metabolic state. Fish, being low in carbohydrates and moderate in protein, aligns well with this lifestyle. The omega-3 fatty acids in fish may even support brain health, which is beneficial during ketosis.

Eating fish while in ketosis is perfectly fine, as long as the overall carbohydrate intake remains controlled. Fish can be incorporated into meals without affecting ketosis, making it a suitable choice for those following a ketogenic diet.
