Summarize:

Most people could stand to be a little healthier. See if your family wants to get in on the action. Talk to your parents about making healthier changes for the whole family. For instance, you could say to your parents, "I don't feel like I'm at a healthy weight, and I'd like to make some changes. What do you think about getting the whole family involved? I think we could all be a little healthier." If possible, it's best to keep junk food out of your house completely. However, if other people in your house still eat it, then you obviously can't do that. You can ask them to hide it away from you, though. Maybe the rest of the family could have a special cabinet for junk food that you don't go into, or maybe they could keep special snacks in their rooms, when possible. If you can't see it, you'll be less likely to eat it. You're going to not do what you're supposed to sometimes. It's just human nature. The key is to do it in moderation. Try to do the right thing about 90 percent of the time, and you'll be fine. Beating yourself up isn't going to help the situation. It's best if you can sit down to a meal with your family, as you can all enjoy a healthy meal together. However, even just sitting down for a meal instead of eating standing up or in front of the television can help you pay attention to what you're eating and learn not to mindlessly plow through your food. If your parents aren't much into cooking, maybe you can learn a few simple, healthy meals to cook for your family once and a while. For instance, baking fish in the oven is fairly simple, and perhaps you can learn how to boil vegetables. If you're interested, ask your parents if you can take a basic cooking class. Breakfast gives you enough energy to start your day. Plus, when you eat breakfast, you won't be as hungry later. That means you won't be as tempted to snack throughout the day. Include a little bit of protein, whole grains, and a fruit or veggie if you can. For instance, try a bowl of oatmeal with some low-fat yogurt and blueberries. You could also have whole-grain toast with boiled eggs and a side of strawberries. This step is easy, though it can be hard if you're busy or a night owl. Basically, getting enough sleep can help you be healthier and lose weight. If you're in school, you need to get 9 to 11 hours every night. Let's face it, life as a kid can be tough sometimes. You've got school and friends and family to deal with. But stress can also make you gain or keep on weight. You're not going to make stress go away completely, but you can learn ways to cope with it.  One way you can deal with stress is to write about it. Keep a journal, and at the end of the day, write about what's bothering you that day. Just writing it can help take a load off your mind.  You can also try meditation or deep breathing. It's not as crazy as it sounds. Deep breathing is literally just taking a moment to focus on your breathing. Close your eyes. Focus only on your breathing. Breathe in slowly through your nose, counting to four in your head. Hold your breath for four counts, then breathe out slowly. Try to block out any other sensations or thoughts. Continue breathing this way for a couple of minutes until you feel yourself calming down.
Get your family involved. Hide the junk food. Forgive yourself. Sit down for meals. Don't skip breakfast. Get enough sleep. Take time to de-stress.
