The right answer is: Storing energy.

Fats and oils (such as olive oil) are often better than their reputation and play a dual role. They constitute a food group and are at the same time a fundamental nutrient. Fats are present in foods of plant and animal origin and provide 9 kcal per gram, twice as much energy as protein and carbohydrates.
