Do you know how important it is to have breakfast? A study of 2，000 teenagers in the US showed that eating breakfast daily is helpful to young people.
According to the study，teenagers who eat breakfast weigh around 5 pounds less than [Z-X-X-K]teenagers who do not. Although they take in more calories (卡路里) in the morning，they are more active during the day because they have more energy. This means they burn more calories than non ¬breakfast eaters. The breakfast does not even have to be very healthy，as eating anything is better than nothing.
The study also showed that eating breakfast keeps teenagers feeling full for longer，so they will not eat too many snacks (零食) later in the day. This is good news as most popular snacks，like sweets and potato chips，are usually unhealthy and full of calories.
Another big advantage of eating breakfast is that it helps teenagers do better at school. This is because it gives them more energy to keep their attention in class.
What's more，a study in the UK showed that adults (成年人) who eat breakfast daily put on less weight and also perform better at work.
Whatever your age is，take time to have breakfast every day.
