Do you want to be healthier but don't know
how? It is very important to exercise and eat the right kind of food to stay
healthy. You do not need to spend all day doing exercise to keep fit. Walking
to school, cleaning the house or climbing stairs every day can help. Unluckily,
many teenagers forget these simple and easy ways to keep fit.
Different kinds of exercise such as
running, swimming and playing football make you feel good. They also help you
to do better at school. To keep a healthy weight, it is important to have the
right amount of calories for your age. A calorie is a measure(测量)
of how much energy food gives you. Girls aged between 12-15 should have 1, 800
calories a day and boys around 2, 000. Doctors suggest that we should eat
lower- fat food instead of fatty food like ice cream, French fries and popcorn.
Vegetables, fruit and grain foods are good choices for daily meals.
