Nowadays nobody has time to eat at home properly so they eat outside. Fast food is the most common food in this century. There are lots of people who eat too much fast food can get obese or overweight. It's not very healthy, because we don't know what they use on our food that we eat, it is not 100% all natural. The few most popular fast food places are McDonalds, KFC, Burger king, etc. it is fine to eat fast food 2-3 a month, not more. Most people get addicted and eat weekly, even daily. This could lead to horrible things & health problems. In my opinion, it's better not to eat Fast food at all.
