When selecting oils for the ketogenic diet, it is best to choose those made from naturally fatty foods. These naturally high-fat foods require less processing to extract the oil. Therefore, I favor oils derived from avocados, olives, and coconuts. For cooking purposes, the recommended oils are extra virgin olive, avocado, almond, walnut, and coconut oil. Animal fats like butter, ghee, lard, and tallow are also great options.
While all cooking oils are carb-free and, therefore, technically keto-appropriate, it is recommended to avoid industrial seed oils like soybean and canola oils. These oils are highly processed, and when heated, they may release harmful chemicals.
Why Not All Oils Are Keto
Most oils are keto, and some people use any oil on the keto diet. However, many sources recommend avoiding Industrial seed oils due to their instability and potential health risks.
Common sources of industrial seed oils, such as margarines, plant-based spreads, and vegetable shortenings, should be avoided. Opting for alternatives like butter and coconut oil, which are solid at room temperature, can be healthier options for cooking and baking.
Trans fats and overly processed polyunsaturated fats should be steered clear of as much as possible. Instead, focus on consuming more stable fats like saturated and monounsaturated fats. Oils such as olive, avocado, and coconut oil, which predominantly contain these stable fats, are better choices for heat exposure.
Even in their unheated form, limiting the consumption of oils high in polyunsaturated fats is advisable. While polyunsaturated fats are a healthy part of the keto diet, it is better to meet the required intake through minimally processed keto-friendly foods such as oily fish.
How to Substitute Non-Keto-Friendly Oils for Keto-Friendly Oils
You can swap your oils at a 1:1 ratio on the keto diet. When it comes to healthy keto fats, replace margarine with coconut oil and vegetable oil with extra virgin olive oil. There are a few factors to keep in mind, though, and the first is flavor. Refined oils are incredibly neutral in taste, while unrefined oils like coconut and extra virgin olive oil may add intense flavor to your dish!
The smoke point is also something that needs to be taken into account also, especially with high-heat cooking. For example, if you stir fry in flaxseed oil, which can only be used raw, you may end up with a rancid burnt tasting dish at best or a kitchen fire at worst. Also, note that oils that solidify at room temperature won’t work well for raw recipes.
What Keto-Friendly Oils are The Healthiest?
Unrefined oils, which are processed minimally, are the healthiest oils for the keto diet. They retain their original flavor, aroma, and nutritional value.
Among the top keto-friendly oils, coconut oil stands out. It not only adds a unique coconut flavor to dishes but also aids in weight reduction, metabolism, and lowering cholesterol levels. Olive oil is another healthy option, recognized for its high fat and antioxidant content. It’s often regarded as one of the most wholesome foods available. The highest quality olive oil is extra virgin olive oil, extracted from the first press of olives and generally the least processed.
Avocado oil, derived from pressed avocados, also makes an excellent choice for cooking. Its rich, buttery flavor is great with just about anything, and it can withstand high temperatures without burning. Grass-fed butter is considered the healthiest butter available, while ghee, with its milk proteins removed, is suitable for those sensitive to dairy and excellent for high-heat cooking.
Animal fats, like almond and walnut oil, are also good guys. Almond oil, rich in healthy fats and vitamin E, has a light, mildly nutty flavor that works well in both sweet and savory dishes. Walnut oil, with its delicate walnut flavors, is best used in raw dishes or as a finishing oil for salads and desserts due to its low smoke point. It’s rich in healthy omega-3 fatty acids.
High-Heat Keto Oils
If you want to make sure your keto oil can handle the heat in the kitchen, it is best to try these:
- Ghee (clarified butter), smoke point 480 degrees.
- Avocado oil, smoke point 520 degrees.
- Pecan oil, smoke point 470 degrees.
Remember that these temperatures are the maximum and may vary by brand, so check the labels or contact the producer to confirm the oil’s smoke point.
FAQs
If it doesn’t tell you on the label, then look at the color. Refined oil has had its impurities removed using a chemical or heat treatment, making it very stable and longer lasting. It can generally be identified by its light colour and neutral taste.
No, no oil will kick you out of ketosis, as they contain no carbohydrates.
Not usually. However, refined avocado oil indeed does exist. I do not recommend it as it loses its delicious buttery flavor.
No, Regina George, it is a fat. Side note: Here is the easiest recipe for vegan butter. Even Amanda Seyfried’s Karen Smith could make it.
Typically, well-known ketogenic sources recommend consuming approximately 70-80% of total daily calories from fat, 5-10% from carbohydrates, and 10-20% from protein.
