Too little dietary fat can lead to several adverse health effects, including hormonal imbalances, nutrient deficiencies, and impaired cognitive function. Fat is essential for the absorption of fat-soluble vitamins (A, D, E, and K) and supports cell structure. A low-fat diet can also result in decreased energy levels and hinder physical performance, particularly for those engaged in endurance activities. Furthermore, insufficient fat can impact skin health and lead to dry skin or brittle hair. It’s crucial to include healthy fats in the diet for overall health.
