Childhood obesity is when a child weighs too much for their age and height. This can happen when they eat too many unhealthy foods and don't get enough exercise or physical activity.
Let's say your body is like a car and food is like fuel. Just like cars need the right kind and amount of fuel to run properly, our bodies need the right kind and amount of food to grow and stay healthy. But sometimes, kids can eat too much of the wrong kind of food, like chips, candy, and soda, and not enough of the good stuff, like fruits, vegetables, and whole grains. When this happens, they can start to gain too much weight and become unhealthy.
Being overweight can cause problems like diabetes, high blood pressure, and heart disease. It can also make it harder for kids to run and play like they want to, and sometimes, it can make them feel sad or unhappy with themselves.
So, it's really important to eat healthy foods and get lots of exercise and physical activity to help our bodies grow up big and strong!
