I have to say that a growing number of people nowadays prefer to eat fast food rather than their meals. Only a few of them have compelling reasons and are forced to do it. Most of people who choose to eat fast food can make a change. Exactly, we have already heard much of the harm about eating fast food, not only on physical but also on mental. The more we have eaten, the more we will be harmed by it. So here, in order to keep our body healthy, it is the right time for us to say “NO” to fast food.
In general, always eating fast food has three major disadvantages.
