Frequently Asked Questions
How much fat should I eat on keto?
On a ketogenic diet, aim for 70-80% of your calories from fat. For a 2000-calorie diet, that's about 155-178 grams of fat per day. Focus on quality fats like those listed in this guide rather than processed oils.
Is MCT oil necessary for keto?
MCT oil isn't necessary but can be helpful, especially when starting keto. It provides quick energy, boosts ketone production, and can help with appetite control. Start with 1 teaspoon to avoid digestive upset.
Can I use vegetable oils on keto?
While technically zero-carb, processed vegetable oils (corn, soybean, canola) are high in inflammatory omega-6 fatty acids. Stick to the healthier options listed in this guide for optimal keto benefits.
How do I store keto fats properly?
Store oils in cool, dark places away from heat and light. Coconut oil can be stored at room temperature. Refrigerate butter and opened bottles of delicate oils like extra virgin olive oil. Ghee can be stored at room temperature.
