Understanding which fats to include and which to avoid is crucial when following a ketogenic diet. Not all fats are created equal, and choosing the right ones can significantly impact achieving and maintaining ketosis. This comprehensive guide will explore the best and worst fats for a keto diet, helping you make informed decisions for your health and wellness journey.
Understanding Fats on a Keto Diet
Fats play a central role in the ketogenic diet, making up about 70-80% of your daily caloric intake. This high-fat, low-carb approach aims to put your body into a state of ketosis, where it burns fat for fuel instead of carbohydrates.
But not all fats are beneficial; some can support your health, while others can hinder your progress. A big plus of the keto diet is its flexibility in food choices, but this also means you need to be vigilant about the types of fats you consume. Healthy fats can help you feel satiated, provide essential nutrients, and support various bodily functions. Conversely, unhealthy fats can lead to inflammation, weight gain, and other health issues. Understanding the difference is key to a successful keto diet.
According to Kristen Mancinelli, R.D., author of "The Ketogenic Diet," "Some low-carb dieters go all out on butter-topped bacon and steak and eat very little produce, but that's not exactly the smartest move." This highlights the importance of balancing your fat sources to avoid potential health risks such as increased cholesterol and weight gain (Mancinelli, 2023).
The Role of Fats in Ketosis
Fats are essential for achieving and maintaining ketosis, the metabolic state where your body burns fat for energy instead of glucose. When you drastically reduce your carbohydrate intake, your liver starts converting fats into ketones, which are then used as an alternative fuel source.
This process not only helps in weight loss but also improves mental clarity and energy levels. One advantage of fats on a keto diet is their ability to keep you feeling full and satisfied. Unlike carbohydrates, which can cause blood sugar spikes and crashes, fats provide a steady source of energy. This can help reduce cravings and make it easier to stick to your diet. Note that not all fats are created equal, so choosing the right ones is crucial for maximizing these benefits.
Best Fat 1: Avocados
Avocados are a fantastic source of healthy fats, making them a staple in many keto diets. They are rich in monounsaturated fats, which are known for their heart health benefits. Additionally, avocados are packed with fiber, vitamins, and minerals, including potassium, which is essential for maintaining electrolyte balance on a low-carb diet.
One benefit here is that avocados can be easily incorporated into various meals. Whether you're adding slices to a salad, blending them into a smoothie, or making guacamole, the versatility of avocados makes them an excellent choice for anyone on a keto diet. Keep in mind that while avocados are nutritious, portion control is still important to avoid overconsumption of calories.

Best Fat 2: Olive Oil
Olive oil, particularly extra virgin olive oil, is another excellent fat to include in your keto diet. It is rich in monounsaturated fats and antioxidants, which have been shown to reduce inflammation and support heart health.
Olive oil is also versatile and can be used in cooking, salad dressings, and even drizzled over vegetables for added flavor. A big plus of olive oil is its relatively neutral taste, making it easy to incorporate into a variety of dishes.
Moreover, it has been linked to numerous health benefits, including improved cholesterol levels and reduced risk of chronic diseases. Note that while olive oil is healthy, it's best to use it in moderation, as it is calorie-dense.
Best Fat 3: Fatty Fish
Fatty fish like salmon, mackerel, sardines, and trout are excellent sources of omega-3 fatty acids, which have numerous health benefits. Omega-3s are known for their anti-inflammatory properties and their role in supporting brain and heart health.
Including fatty fish in your keto diet can help you achieve a balanced intake of essential fats. One advantage of fatty fish is that they are also a good source of high-quality protein, which is important for maintaining muscle mass and overall health.
Additionally, fish like salmon are rich in vitamins and minerals such as vitamin D and selenium.

Best Fat 4: Nuts and Seeds
Nuts and seeds are packed with healthy fats, fiber, and protein, making them an excellent addition to a keto diet. Options like almonds, walnuts, chia seeds, and flaxseeds are particularly beneficial due to their high content of omega-3 fatty acids and antioxidants.
These nutrients can help reduce inflammation and support overall health. Keep in mind that while nuts and seeds are healthy, they are also calorie-dense. It's essential to consume them in moderation to avoid exceeding your daily caloric intake.
A small handful of nuts or a tablespoon of seeds can be a satisfying and nutritious snack, providing you with essential nutrients without derailing your keto goals.

Best Fat 5: Eggs
Eggs are a versatile and nutrient-dense food that fits perfectly into a keto diet. They are an excellent source of high-quality protein and healthy fats, including omega-3 fatty acids if you choose eggs from pasture-raised or omega-3 enriched hens.
Eggs also contain essential vitamins and minerals such as vitamin B12, choline, and selenium. One benefit here is that eggs can be prepared in numerous ways, making them a convenient option for any meal.
Whether you prefer them scrambled, boiled, poached, or in an omelet, eggs can provide a quick and satisfying meal that aligns with your keto diet. Note that while eggs are highly nutritious, it's best to pair them with other keto-friendly foods to ensure a balanced intake of nutrients.
Best Fat 6: Cheese
Cheese is another excellent source of fat and protein for those on a keto diet. It is rich in calcium and other essential nutrients, making it a nutritious addition to your meals. Varieties like cheddar, mozzarella, and Parmesan are particularly low in carbs, making them ideal for keto.
A big plus of cheese is its versatility. It can be used in a variety of dishes, from salads and casseroles to keto-friendly pizzas and snacks. However, it's essential to consume cheese in moderation, as it is calorie-dense and can contribute to overconsumption if not portioned properly.
Keep in mind that some cheeses may contain added ingredients, so it's best to choose natural, unprocessed varieties.
