Saturated fats are typically solid at room temperature. The majority of saturated fats are found in meat and dairy products. Some products have fat blended in while others are essentially all fat like butter. Unsaturated fats are usually liquid at room temperature. They are usually extracted from seeds.
Many people consider fat a substance to be avoided at all costs.
However, the body needs fat. Fat provides protection for some of the body's organs by holding them in place and cushions any impact. Women usually have an extra layer of fat under their skin which helps insulate body temperature. Fat also aids in the absorption if fat-soluble vitamins and minerals in the small intestine. In theory, when too few calories are eaten, the body should burn its stores of fat and weight loss should occur.
