Energy Source
Dietary fats are a major and concentrated source of dietary energy, providing 9kcal of energy per gram, compared with 4kcal per gram for carbohydrates and proteins. This makes fats an efficient way to fuel your body, especially during long periods of physical activity or when you need sustained energy.
Support for Bodily Functions
Fats are not just about energy. They play crucial roles in supporting various bodily functions. For instance, fats are essential for the absorption of fat-soluble vitamins like A, D, E, and K. They also help in the production of important hormones and provide insulation and protection for your organs.
Fats are indispensable for a number of important biological functions including growth and development.
Balancing Saturated and Unsaturated Fats
It’s important to balance your intake of saturated and unsaturated fats. While both types are necessary, unsaturated fats are generally considered healthier for your heart. Balancing these fats can help you maintain optimal health and reduce the risk of chronic diseases.
- Saturated Fats: Found in animal products and some plant oils.
- Unsaturated Fats: Found in fish, nuts, seeds, and vegetable oils.

Energy Storage
Fats are a concentrated source of energy. When your body has extra calories, it stores them as fat for future use. This stored energy can be crucial during times when food is scarce or when you need extra energy for activities like running or working out.
Insulation and Protection
Fats play a vital role in keeping your body warm and protecting your organs. They act as a cushion, safeguarding vital organs from physical shock. Additionally, fats help in maintaining body temperature by providing insulation.
Regulation and Signaling
Healthy fats are essential for hormone production and regulation. They help in the absorption of fat-soluble vitamins like A, D, E, and K, which are crucial for various bodily functions. Moreover, fats are involved in cellular signaling, which helps in maintaining healthy cell membranes and overall bodily functions.
Good quality fat gives your body energy, keeps you warm, and helps you absorb certain vitamins. And there are some fats that you can only get from food.

Types of Fats
Saturated Fats
Saturated fats are often considered the “bad fats” because they tend to be more solid at room temperature, like butter. These fats can raise your LDL (bad) cholesterol levels, which can increase your risk of heart disease. It’s important to limit your intake of saturated fats to maintain a healthy diet.
Unsaturated Fats
Unsaturated fats are generally considered the “good fats” and are usually liquid at room temperature. They can be further divided into monounsaturated and polyunsaturated fats. These fats are beneficial for heart health and can help reduce bad cholesterol levels. Certain types of these fats are still beneficial over another. For example, extra virgin Olive Oil is a superior oil to vegetable or sunflower oil for cooking due to amount of fat molecules within the oil.
- Monounsaturated fats: Found in olive oil, canola oil, and avocados.
- Polyunsaturated fats: Found in fish, sunflower oil, and walnuts.
Essential Fatty Acids
Essential fatty acids are types of polyunsaturated fats that your body cannot produce on its own. These include omega-3 and omega-6 fatty acids, which are crucial for brain function and cell growth. You can find these in fish, flaxseeds, and chia seeds.
For a healthy diet, it is important that most of the fats we eat are unsaturated.
