What is the deficiency for not enough fats?

A deficiency in dietary fats can lead to several health issues, including dry skin, hair loss, and hormonal imbalances, as fats are essential for hormone production and nutrient absorption. Additionally, insufficient fat intake can impair brain function, since the brain relies on fats for structure and energy. It may also result in deficiencies in fat-soluble vitamins (A, D, E, and K), which are crucial for various bodily functions.
