What You Need to Know
Pesto is considered keto-friendly because its main ingredients—Parmesan cheese, olive oil, basil, and pine nuts—are low in carbohydrates and high in healthy fats. This combination aligns perfectly with the ketogenic diet, which emphasizes high-fat and low-carb foods to promote ketosis, a metabolic state where the body burns fat for energy instead of carbohydrates.
For those on a keto diet, incorporating pesto can enhance the flavor of various dishes without compromising carbohydrate limits. Use it as a sauce for grilled meats, a topping for vegetables, or a spread on keto-friendly bread. Just be mindful of portion sizes to keep your overall carb intake within your daily goals.
