Calories are a measure of energy you get from food. The first law of thermodynamics or energy says:
Making drastic changes to the way we eat or how much we eat usually doesn't result in long-term success with weight loss. For instance, skipping meals or eating very small quantities of food can lead to eating too much at the next meal. Our bodies were designed to protect us from starvation, so hunger pains can often get the better of us. Going for a long period without eating or skipping meals can also cause our bodies to burn less energy in an attempt at conservation.

On the other end of the weight equation is the number of calories burned. If your child burns more calories than he or she eats and drinks, he or she will lose weight.
Unfortunately, nearly 75 percent of all American youths age 12 to 21 are not vigorously active on a regular basis. This is not surprising given that more than 60 percent of adults in the United States do not engage in levels of physical activity necessary to provide health benefits.

Parents should step up both their own and their children's amount of physical activity. The patient education article Exercise Tips can help.
