If you're worried about your weight, healthy eating and exercising may help ease your worries. To begin with, being more active is important for keeping your weight in check. Choose an activity that makes you breathe hard and sweat a bit. Discover some great activities you can do by yourself, with a friend, or with a big bunch of people. There are fun ideas for every situation—you don't need to join a teem to be active! Doctors usually don't recommend cutting back on the amount of food you eat, although your doctor may suggest better food choices, such as choosing foods with less fat and sugar in them. Because you are still growing, you need to keep eating and you also need to choose your foods wisely. You can talk with your family and get everybody involved in eating better foods and exercising more. Keep your metabolism, or the rate at which you consume energy from food, at a high speed by staying active. The faster your body uses energy, which comes from food, the less likely you are to be at an unhealthy weight. In fact, small changes in your diet and activities can add up to big changes in how you look and feel. For example, you can cut down on your TV, computer, or video game time by 30 minutes a day. Never skip breakfast and eat a good one with fruits, grains, and vegetables. Again, you can start a water habit. If you're thirsty, drink water instead of sugary juice, iced tea, or soft drinks. Remember that not only will eating healthily and exercising more keep you at your ideal weight, you'll feel better about yourself, too.
