Using air fryers can promote weight loss because a higher intake of fried foods has direct links with higher obesity risk. This is because deep-fried foods tend to be high in fat and calories. Frying food in oil can cause dangerous compounds to develop, such as acrylamide. This compound forms in certain foods during high-heat cooking methods, such as deep-frying. By switching to air frying, people can lower the risk of having acrylamide in their food.
