Which of the following is NOT a function of fats?

Fats, also known as lipids, serve several important functions in the body, but regulation of blood sugar is not one of them. The primary roles of fats include providing a protective layer around vital organs, aiding in insulation that helps maintain body temperature, and serving as a crucial storage form of energy.

Protection of vital organs is achieved through a layer of fat that cushions and shields organs from physical impact. Insulation is vital for maintaining body temperature, as subcutaneous fat helps preserve heat while also providing a barrier against cold. As for energy storage, fats store more energy per gram than carbohydrates or proteins, making them an efficient form of energy reserve for the body.

On the other hand, blood sugar regulation primarily involves carbohydrates and proteins, with hormones such as insulin playing a significant role in maintaining blood glucose levels. Fats may indirectly influence how the body processes carbohydrates, but they are not directly responsible for the regulation of blood sugar levels.
