How to Choose Cooking Oils for a Low-Carb Diet
Every pure oil is zero-carb, so the real decision criteria on a low-carb diet are fat quality, heat stability, and source integrity. Prioritize cold-pressed or expeller-pressed oils over solvent-extracted refined oils. Match smoke points to cooking methods. avocado oil or ghee for high-heat cooking, olive oil for medium heat, and MCT/nut oils for cold applications only. Minimize or eliminate high-omega-6 seed oils (corn, canola, soybean, vegetable blend) because chronic omega-6 excess promotes the inflammation that a well-designed low-carb diet aims to reduce. Buying in modest quantities and storing away from heat and light preserves quality between uses.
