                                                           How to Become Fit?

     Healthy eating habit along with regular exercise is the only way to become fit. If you have the correct

number of calories and exercise regularly, you will lose weight, keep fit, and feel great, too.

     During your teenage years, it is important to give your body the energy it needs. If you skip (跳过) meals,

you won't get enough calories, and then you will feel tired. By the way, calorie is just another word for energy.

About 50% of your calories should come from rice, bread, vegetables and fruit. You also need to drink a lot of

water, 6 to 8 glasses a day. Water helps keep your system clean. Drinking enough water will make your skin

better and make you healthy.

     Exercise is something that can help to make you look good, feel good and be healthy. Experts suggest that

teenagers spend at least 30 minutes exercising, five times a week. That is easy to do! You can walk or ride

your bike to school, and do sports at school. However, teenagers often give up sports, saying they have no

time left after their studies. In fact, doing exercise can help them sleep better at night and increase their ability

to focus on their study.

    If you follow the suggestions above, you will look and feel much better and become fit.
