What is the function of fats in the body?

Fats serve several vital roles in the body, and one of their primary functions is to store energy and provide cushioning for vital organs. Fats are a dense source of energy, delivering more than double the calories per gram compared to carbohydrates and proteins. This stored energy is crucial for times when the body requires additional fuel, such as during prolonged exercise or between meals.

Additionally, fats play a protective role by cushioning organs, which helps to absorb shock and prevent injury. This protective layer surrounding organs, such as the kidneys and heart, ensures that they remain safe from physical trauma.
