If you go to a fast food restaurant.you will probably see a lot of teenagers. Today,many teenagers are overweight,and some of.this is because of their bad eating habits., Most teenagers love food with a lot of fat,oil,salt,and sugar. People often call this kind of food "junk food".
But. bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don't have breakfast before they go to school. During the day,some don't have a proper meal for lunch.

They preferred to eat food with a lot of salt,sugar,or fat.

★Teenagers shouldn't eat too much junk food.
