Fats are an essential source of energy and play important roles in cell membranes, hormones, the brain, nervous system and absorption of fat-soluble vitamins.
The quality and source of fat matter.
Prioritize minimally processed sources such as olive oil, avocados, nuts, seeds, eggs, fatty fish and other whole-food sources of healthy fats, while limiting highly processed fats and foods rich in refined ingredients.
Omega-3 fatty acids, particularly those found in fatty fish, are important structural components of the brain and support normal cardiovascular and metabolic function.
Fats and Ketones When carbohydrate availability is sufficiently low, the liver can convert fatty acids into ketone bodies. Ketones can then serve as an alternative energy source for the brain and other tissues.
This is one reason why dietary fat is more than simply a source of calories — it can also participate directly in how the body produces and uses energy.
Choose quality fats, prioritize whole foods, and understand that the type and context of fat matter more than simply trying to eat “more fat.”
