Choosing the right cooking oil is important on a Keto Diet because healthy fats help induce ketosis when low levels of carbohydrates are consumed. When it comes to avocado oil vs olive oil, both are low-carb, Keto-friendly fats, but they perform very differently in the kitchen. Their smoke points, flavors, nutrient stability, and uses can affect food quality, taste, and even fat oxidation. So, let’s learn what you need to know about cooking with avocado oil vs olive oil on a Keto Diet.
Let’s start by comparing the different features of avocado oil vs olive oil to be able to decide which one is a better choice for cooking on a Keto Diet.
One of the most important features we need to consider when choosing the proper oil for cooking is the smoke point. Let’s dig in and find out how avocado oil vs olive oil performs in high-heat cooking.

Smoke point determines how well a cooking oil tolerates heat before breaking down into harmful compounds and losing nutritional value.
On a Keto Diet, where fats make up a large portion of daily calories, choosing a heat-stable oil is essential. Smoke point is also important on Keto because:
Refined avocado oil has one of the highest smoke points of any cooking oil, reaching about 480-520°F (250-270°C) [1].
This means avocado oil is suitable for high-heat Keto cooking methods such as pan-frying, grilling, searing, roasting, and air frying. At these temperatures, avocado oil remains stable, resists oxidation, and maintains a neutral flavor.
Extra virgin olive oil (EVOO) has a lower smoke point, ranging from 375-410°F (190-210°C). While olive oil is still suitable for low-to-medium heat cooking, it can degrade more quickly at high temperatures [2].
When olive oil exceeds its smoke point, its beneficial polyphenols decline, and the oil can develop a noticeable bitter or acrid taste [3].
The table below summarizes the comparison of avocado oil vs olive oil regarding smoke point to help you choose more easily.

As the table above shows, avocado oil is better for high-temperature Keto cooking, while olive oil performs better in lower-heat cooking or raw dishes.
On a Keto Diet, in addition to the smoke point, you need to consider the effect of the oil on ketosis, which is one of the main goals of a Keto Diet.

Comparing avocado oil vs olive oil regarding macronutrients, we find out that both oils are 100% fat with zero carbohydrates, meaning they are fully Keto-friendly.
Neither oil will spike blood sugar or insulin, and neither will kick you out of ketosis if you consume them in normal amounts.
However, they differ in fat stability and digestion. Avocado oil is stable when heated, meaning it maintains its fatty acid structure even during high-temperature cooking. This makes it a reliable energy source for ketosis in Keto meals [4].
Olive oil is also rich in monounsaturated fats, especially oleic acid, and antioxidants. Extra virgin olive oil contains polyphenols that support heart health and reduce inflammation, especially when it is consumed raw or heated gently [5].

Olive oil is also great in Keto baking and Keto fat bombs because it has a neutral flavor. It blends well into batters and desserts without adding bitterness or herbal notes.

In short, choose avocado oil when you do not want to taste the oil, but choose olive oil if you want to enhance the dish’s flavor.
Taste is one of the most noticeable differences between avocado oil and olive oil, especially for Keto dieters who use fats as a source of flavor.
Avocado oil has a light, neutral flavor that makes it almost invisible in cooked dishes. This allows spices, herbs, and proteins to be the main taste [8].
Olive oil, especially extra virgin varieties, has a distinct fruity, grassy, or peppery taste. While this can improve salads and Mediterranean-style Keto dishes, it can clash with certain foods when overheated [9] [10].
