In my openion , i think eating fast food , it's not good because it not healthy food. Children, teenagers, and even young adults are used to eating unhealthy foods. Some people have no clue that fast foods have extremely high levels of sugar and fats where as it tends to settle in certain areas of your body
In addition Fast food is very expensive. There is no such thing as a "bad" food. All foods can fit into a healthy meal plan. It's true that fast food is usually high in fat, calories, cholesterol, and sodium, but eating fast food every once in a while is not going to cause you problems. If you eat too much fast food over a long period of time, though, it can lead to health problems like high blood pressure, heart disease, and obesity.
