Which of the following is NOT a function of dietary fats?

Dietary fats play several essential roles in the body, but building muscle mass is not one of their primary functions. Instead, muscle mass is primarily developed through protein intake and physical exercise, particularly resistance training, which stimulates muscle growth. While fats are vital for overall energy and various physiological functions, they do not directly contribute to the synthesis of muscle tissue.

Fats serve crucial functions such as energy storage, providing a concentrated source of energy that the body can tap into when needed. They also play a significant role in insulation, helping to maintain body temperature by providing a protective layer beneath the skin. Additionally, dietary fats are critical for the absorption of fat-soluble vitamins (A, D, E, and K), which are necessary for various bodily functions, including vision, bone health, and blood clotting. By facilitating the absorption of these vitamins, fats contribute to overall nutrient utilization in the body.
