What is one reason som fat is necessary?

One reason some fat is necessary is that it plays a crucial role in hormone production and regulation. Fats, particularly healthy unsaturated fats, are involved in the synthesis of hormones such as estrogen and testosterone, which are essential for various bodily functions, including metabolism, reproductive health, and mood regulation. Additionally, fats help absorb fat-soluble vitamins (A, D, E, and K), supporting overall health.
