Fats vs. Oils — What's the Difference?
By Tayyaba Rehman — Published on January 2, 2024
Fats are solid at room temperature, derived from animals and plants. Oils are liquid at room temperature, primarily from plants. Fats store energy; oils facilitate cooking.

Key Differences
Fats and Oils both belong to the same family of macronutrients known as lipids. However, their characteristics and applications vary considerably. Fats, in a general sense, are more solid at room temperature. They can be found in both animal products like butter and lard and certain plant sources such as coconut and palm. Oils, conversely, remain liquid at room temperature and are predominantly derived from plants, like olive, sunflower, and canola.
Chemically speaking, Fats typically have a higher proportion of saturated fatty acids, contributing to their solidity. These saturated fatty acids, when consumed in excess, can be linked to health concerns, especially related to heart diseases. Oils, on the other hand, tend to have a higher concentration of unsaturated fatty acids, which are often deemed healthier. These unsaturated fatty acids can be broken down further into monounsaturated and polyunsaturated fats.
In culinary applications, the distinction between Fats and Oils becomes more palpable. Fats, due to their solid state, are often used for baking, flavoring, and creating textures in foods. Butter, for instance, provides flakiness in pastries. Oils, being liquid, are popularly used for frying, sautéing, and as dressings in salads.
Additionally, the sources from which Fats and Oils are derived can often dictate their nutritional profiles. Animal-based fats might contain cholesterol, while plant-based oils usually do not. Nonetheless, both Fats and Oils are essential in a balanced diet, providing energy, aiding vitamin absorption, and offering essential fatty acids.

Common Curiosities
Which is healthier: Fats or Oils?
Both can be healthy; plant-based Oils are often high in unsaturated fats, while some Fats, like avocado, are nutrient-dense.
Can cooking with Oils make them unhealthy?
Overheating Oils can produce harmful compounds and trans fats.
Why are trans Fats harmful?
Trans Fats can raise bad cholesterol, lower good cholesterol, and increase heart disease risks.
Can Oils turn into Fats?
When Oils cool down or are hydrogenated, they can solidify and behave like Fats.
Are all Fats from animal sources?
No, some Fats, like coconut fat, come from plants.
Are Oils calorie-dense?
Yes, like all fats, Oils are energy-dense, containing about 9 calories per gram.
Do all Oils have the same smoking point?
No, each Oil has a unique smoke point; some, like avocado oil, have a high smoke point, while others, like flaxseed oil, have a low one.
Which Oils are best for high-temperature cooking?
Oils with high smoke points, like canola or grapeseed Oil, are suitable for high-temperature cooking.
Why are saturated Fats controversial?
Excessive intake can lead to heart disease and other health concerns.
What's the role of Fats in the body?
Fats provide energy, support cell growth, protect organs, and help nutrient absorption.
Why do some Fats remain solid at room temperature?
The saturation level of fatty acids influences the consistency; higher saturation leads to solidity.
