What is one of the effects of fat deficiency on the body?

Fat deficiency can lead to various effects on the body, one of which is dryness in multiple areas, including the skin, hair, and mucous membranes. Fats are essential for maintaining the integrity of cellular membranes and are crucial for the absorption of fat-soluble vitamins such as A, D, E, and K. When fat intake is insufficient, the body struggles to retain moisture, leading to dryness. This can manifest as dry skin, brittle hair, and dry eyes, ultimately affecting overall health and well-being.

The other options do not directly relate to the consequences of fat deficiency. For instance, weight gain typically arises from an excess of calories rather than a deficit, while improved energy levels are more likely associated with a well-rounded intake of nutrients, including fats. Increased appetite might suggest a nutrient imbalance or deficiency, but it isn’t a direct consequence of low fat intake specifically.
