According to the 2003-2004 National Health and Nutrition Examination Survey, an estimated 17 percent of American children and teenagers between the ages of 2 and 19 could be considered overweight. These statistics only continue to grow as American adult dietary habits get passed down to their children. Luckily, the same methods that help adults lose weight, can also be utilized to help children lose weight as well.
Creating a Calorie Deficit
For a child to lose weight, there must first be a calorie deficit between how many calories are consumed through food, and how many calories are burned while performing regular bodily functions. There are two main ways to create a calorie deficit. The first way is through exercise. For kids, simple changes in habits, such as less television and video games, and more playing outside or taking part in school sports, can quickly burn enough calories to obtain a calorie deficit. Another way to create a calorie deficit is through diet. Because children need calories to grow and develop properly, it is not recommended to drastically cut calories from a child's diet. Instead, a focus on healthy foods (such as those listed by the USDA food pyramid) instead of sweets and processed meals, can help reduce the amount of calories, while still providing the nutrients needed for healthy development.
Breaking Down Triglycerides
Once a calorie deficit has been achieved, the body has to turn to fat storage for energy. This is where the child will lose the weight from. To turn the fat storage into energy, the body must first break down the triglycerides into smaller parts. When the brain senses that not enough calories have been consumed to function at normal levels, it triggers the release of hormones, such as epinephrine, that activate an enzyme called lipase. Lipase works on triglycerides and breaks them down into glycerol and fatty acids. Next, both glycerol and the fatty acids need to be broken down into a substance called acetyl-CoA. Glycerol is broken down into acetyl-CoA by a process called glycolysis, while the fatty acids are broken down through a process called beta oxidation.
Fat to Waste
Once the fat has been broken down into acetyl-CoA, it is able to be broken down even further into hydrogen and carbon dioxide through a process called the Krebs cycle. The hydrogen moves on in the process, and through a chemical reaction is combined with oxygen to create water and energy. The remaining water can then exit the body as waste through the child's urine or sweat. The carbon dioxide also exits the body as waste, but instead of through urine, it is exhaled out of the child's lungs. With the fat transformed into energy and waste, after the waste exits the body, the child will weight less.

If we exercise in front of our children, then we are setting a beautiful example that kids will most likely follow. When they are very young especially, they want to spend time with us. So why not do something active and fit with them. Workout with them. Make space for your kids and get them a tiny pair of weights. They go down to 1 pounders.
The WII FIT game is a good way to have fun with them. But you don't need a video system, but it might be a way of stepping to their level. My four year old loves WII FIT yoga. She has no idea how she is really doing with her balance, but the virtual trainer tells her great job, like a personal trainer would praise a client for getting through a workout set.
I am an avid P90X user. I am getting ready to finish my second round of the program. My 4 year old daughter and 13 year old son have both come into the room and done some of the workouts with me. Make it FUN!
I am a true believer that we can turn this epidemic and negative reputation of the "most obese and unhealthy town in America" (Huntington WV) upside down. It starts with us parents and it starts at home. We need to get up and get active and before you know it, the kids adapt just like brushing their teeth in the morning or taking a bath. They are truly sponges when they are very young. They see us exercising and they will too.
