Fats are not very popular among people trying to lose weight, but they are as important for our bodies as other macronutrients. Fats are responsible for cushioning organs in our bodies and they serve as hormonal regulators and participate in the process of absorbing vitamins A, D, E and K. A diet too low in fat can lead to unpleasant and dangerous health problems – hormonal diseases, skin problems, libido and menstrual disorders and more. We need fat for our bodies to function properly. It is necessary to distinguish between different types of fats and to replace bad fats with good ones necessary for our health.
