Answer:
Fast food is a mass-produced food created for commercial resale and with a strong priority placed on "speed of service" vs. other relevant factors involved in culinary science. Although a variety of food can be "cooked fast", "fast food" is a commercial term limited to food sold in a restaurant or store with frozen, preheated or precooked ingredients, and served to the customer in a packaged form for take-out/take-away. Fast food is popular because the food is inexpensive, convenient, and tastes good. However it is made with unhealthy ingredients such as sugar, fats, refined grains, etc. instead of healthy ingredients such as lean meats, vegetables, fruits, whole grains, etc.
