Fast food refers to food that is prepared and served quickly. It is typically ordered at a counter or drive-thru and does not require wait staff. People often choose fast food because it is inexpensive, convenient to obtain, and usually tasty. However, fast food tends to be highly processed and less nutritious than home-cooked meals, contributing to health issues like obesity and increased risk of heart disease if consumed frequently. Popular fast food franchises have established locations in shopping complexes and other public places worldwide, including multiple options in Malaysia.
