The ketogenic (keto) diet, characterized by high fat, moderate protein, and very low carbohydrate intake, has gained immense popularity for its potential benefits in weight loss and overall health improvement. One of the key aspects of a successful keto diet is choosing the right types of fats. Among the various options available, sesame oil has emerged as a frequently discussed choice. This article delves into the suitability of sesame oil for a keto diet, exploring its nutritional composition, potential benefits, and optimal usage.
Understanding Fats on Keto
On a keto diet, fats become the primary source of energy, replacing carbohydrates. Therefore, selecting healthy and appropriate fats is crucial for maintaining optimal health, well-being, and sustained ketosis. While any plant-based oil provides a pure source of fat with zero carbs and protein, the quality and type of oil can significantly impact your overall health. The most beneficial oils are used to supplement meals and add extra fat to low-carb dishes through cooking, frying, baking, or drizzling.
Is Sesame Oil Keto-Friendly?
Yes, sesame oil is generally considered keto-friendly. Since carbohydrates are severely restricted on the keto diet, the zero-carbohydrate content of sesame oil makes it an ideal choice. It can be a valuable addition to keto-friendly meals when used correctly.
Nutritional Composition of Sesame Oil
Sesame oil is derived from sesame seeds and is sometimes referred to as gingelly or til oil. It has a distinct nutty flavor and is widely used in various Asian cuisines, including Chinese, Indian, Korean, and Thai dishes.

- High in healthy fats: Sesame oil is rich in both monounsaturated and polyunsaturated fats, which are essential for a healthy cardiovascular system. Unsaturated fats, like those found in sesame oil, may help reduce the risk of cardiovascular disease when used in place of oils high in saturated and trans fats.
- Omega-6 fatty acids: Sesame oil contains omega-6 fatty acids, which play a crucial role in maintaining a healthy cardiovascular system.
- Antioxidants: Sesame oil is abundant in antioxidants, which help reduce oxidative damage that can lead to cellular damage and disease.
- Sesamin: Sesame oil contains sesamin, a lignan believed to help reduce inflammation and protect against oxidative damage in the brain.
Potential Health Benefits of Sesame Oil on Keto
Beyond its keto-friendliness, sesame oil offers several potential health benefits:
- Cardiovascular Health: The omega-6 fatty acids in sesame oil contribute to a healthy cardiovascular system. Replacing oils high in saturated and trans fats with sesame oil may reduce the risk of cardiovascular disease.
- Brain Health: Sesamin, a lignan found in sesame oil, may help reduce inflammation and protect against oxidative damage in the brain, potentially benefiting brain health.
- Blood Sugar Control: The healthy fats in sesame oil may improve insulin sensitivity and reduce blood sugar levels.
- Anti-Inflammatory Properties: Research suggests that the antioxidants, lignans, and polyunsaturated fatty acids in sesame oil may help reduce inflammation, joint pain, and stiffness associated with arthritis.
- Skin Health: Topical application of sesame oil may help heal wounds and burns quickly.
- Sleep Quality: Applying sesame oil to the scalp before bedtime may induce a deeper, more restful sleep.
- Hair Health: Topical use of sesame oil on hair may nourish the scalp, strengthen the roots, and promote hair growth.
Types of Sesame Oil
Sesame oil is made by pressing and grinding sesame seeds to extract the oil. Pressure or heat is often used to force the oil out of the seeds, and substances like citric acid may be added to preserve freshness and improve shelf life. Cold pressing and heating each produce different types of sesame oil, which vary widely in taste, nutrition, and color.
- Toasted Sesame Oil: This oil has a distinct and intense flavor, making it ideal for adding a finishing touch to dishes. Since it's primarily used for its flavor, it should be used sparingly and not exposed to high heat.
- Unrefined Sesame Oil: Unrefined sesame oil is full of the natural goodness that only comes with careful, minimal processing. It carries a mild and light flavor with a gentle hint of tahini.
- Cold-Pressed Sesame Oil: Cold-pressed sesame oil is perfect for sautéing and other cooking applications. It’s great with starches like rice, pasta, and other dishes.
How to Incorporate Sesame Oil into Your Keto Diet
Sesame oil can be incorporated into your keto diet in various ways:
- Salad Dressings: Use sesame oil as a base for salad dressings to add a nutty flavor.
- Cold Dishes: Drizzle sesame oil over cold dishes for added flavor and healthy fats.
- Stir-fries: Add sesame oil to stir-fries for an authentic Asian flavor.
- Marinades: Use sesame oil in marinades for meats and vegetables.
- Baked Goods: Sesame oil can be used in place of vegetable oils in some baked goods recipes.
- Toppings: Sprinkle sesame seeds over salads or use them to make Everything Bagel Seasoning and add to Creamy Egg Salad or sprinkled over Deviled Eggs. Sesame seeds go well with salmon as they add both crunch and flavor.
- Tahini Dressing: Versatile and can be drizzled over any vegetables or proteins. Try with some Grilled Eggplants, Grilled Eggplant & Red Pepper Salad, Chargrilled Broccolini or Smoky Roasted Mushrooms!
Considerations for Using Sesame Oil on Keto
While sesame oil offers several benefits, it's essential to consider the following:
- Moderation: Although sesame oil is a healthy fat, it's crucial to consume it in moderation, as with any fat source on the keto diet.
- Heating: Less refined sesame oils should be avoided when cooking at high temperatures, as the fats can break down and become toxic. Refined sesame oil has a high smoke point and is more suitable for high-heat cooking.
- Omega-6 Content: While sesame oil contains omega-6 fatty acids, it's essential to maintain a balanced omega-6 to omega-3 ratio in your diet.
- Antioxidant Protection: The omega-6 fats in sesame are protected by powerful natural antioxidants called sesamin and sesamolin. As sesamolin is heated, it is thermally converted into an even more powerful antioxidant called sesamol.
Other Keto-Friendly Oils and Fats
In addition to sesame oil, several other oils and fats are suitable for the keto diet:

- Extra Virgin Olive Oil: Excellent for cooking, drizzling, and using in keto dressings. It is resistant to oxidation when used in frying and cooking tests.
- Coconut Oil: Refined coconut oil is suitable for high-heat cooking, while unrefined coconut oil adds a distinct coconut aroma to dishes. Coconut oil contains medium-chain triglycerides (MCTs), which promote ketone production.
- MCT Oil: MCT oil is known for its ability to increase ketone levels. It can be added to meals, smoothies, salad dressings, or ketoproof coffee.
- Avocado Oil: With a similar fatty acid profile to olive oil, avocado oil is a great option for keto.
- High-Oleic Sunflower/Safflower Oil: These oils are also good choices for keto due to their high monounsaturated fat content.
- Red Palm Oil: Palm oil can be a great addition to the keto diet, but its bold flavor may not pair well with desserts and sweets.
- Animal Fats: Animal fats like butter, clarified butter (ghee), lard, leaf lard, lamb tallow, mutton tallow, and duck fat are also keto-friendly options.
Fats and Oils to Limit or Avoid on Keto
To maximize the benefits of a keto diet, it's best to limit or avoid certain fats and oils:
- Canola Oil: Despite its relatively low cost and high smoke point, canola oil is not as stable as other keto-friendly oils.
- Vegetable/Seed Oils High in Polyunsaturated Fats: Oils like sunflower oil, rice bran oil, and grapeseed oil are high in polyunsaturated fats and should be limited.
- Partially/Fully Hydrogenated Oils: These oils should be avoided altogether due to their negative impact on health.
The Importance of Whole Food Fat Sources
While pure fats and oils can supplement a keto diet, it's crucial to prioritize whole food sources of fat. High-fat, minimally processed foods like fatty cuts of meat, fish, eggs, full-fat cheese, nuts, seeds, and avocado should form the foundation of your fat intake.
