Preventing childhood obesity requires making decisions about how your family eats, exercises, and spends time together. Parents who set a good example for their children can assist them in leading healthy lifestyles. Obesity puts youngsters at risk for medical disorders that can harm their health now and in the future. Serious disorders such as type 2 diabetes, high blood pressure, and high cholesterol, which were traditionally considered adult diseases, are among them. Childhood cardiovascular risk factors (such as high blood pressure, high cholesterol, and diabetes) can lead to grownup heart disease, heart failure, and stroke. Preventing or treating childhood obesity may help protect children from developing these problems as they grow older. Obese children may also struggle with emotional issues (such as low self-esteem) and may be mocked, bullied, or rejected by their classmates. Children who are overweight are at risk for a variety of health problems. The body mass index (BMI) is a formula that calculates a person’s body fat percentage based on their height and weight. However, calculating BMI on your own can be difficult.
