Here's why:
* Structure: Fats are made up of glycerol molecules attached to three fatty acid chains. These long chains contain a lot of carbon-hydrogen bonds, which are packed with energy.
* Energy Density: Fats have the highest energy density of all macronutrients (carbohydrates, proteins, and fats), providing approximately 9 calories per gram, compared to 4 calories per gram for carbohydrates and proteins.
* Storage: The body stores fat efficiently, making it an ideal source of long-term energy reserves.
While carbohydrates are the body's preferred energy source for immediate use, fats are crucial for providing energy during prolonged periods of fasting or strenuous activity.
