What Do Doctors Use to Check If a Child Has Obesity?
Doctors use a measurement called the Body Mass Index (BMI) to tell if someone has obesity. Doctors can measure a person’s BMI when they consider body fat, height and weight.
Fast Facts About Obesity
- Obesity is not simply a matter of calories in and calories out. How the body uses food for energy and storage is a complex process. It involves many hormones and chemicals (called neurotransmitters).
- Food does not always cause obesity. Obesity is a true disease that doctors can diagnose. Obesity is mostly caused by a problem with how the body regulates the use of food for energy balance.
- Obesity is not a choice. It is also not a sign that someone lacks willpower or self-control.
How Can I Prevent Childhood Obesity?
There are many ways you can prevent obesity:
Be a Positive Role Model
- Set a good example of what it means to live a healthy, active lifestyle.
- Keep in mind that the overall picture of health is the key. It is a good idea to eat a variety of colorful, healthy foods and enjoy your favorite treats every once in a while.
Keep It Positive
- Keep conversations about food positive. Food is a source of joy and nourishment. It is not the enemy or something that brings about sadness, guilt or shame.
- Focus on all the benefits of making healthy food choices, like being able to play a favorite sport. Do not shame your child for their food choices, weight or feelings.
Make It Fun
- Involve your child in food shopping and cooking.
- Use rewards for positive behavior that do not involve food. For example, a trip to the park.
- If your child asks for food, ask them if they are truly hungry or if they just feel like eating it. This will help them build the skills to make healthy, thoughtful choices out of true hunger.
