Moreover, the question pop up in our head is why children with obesity are not good at school. 

According to the report by Erickson H (2019)  inChildhood obesity often affects academic performance: now we may know why.” Apart from academic performances, an obese child deals with several social problems in school premises as they get bullied and ignored by peers. That’s why they find it hard to be at school, and they start avoiding going to school. 

Thus, due to overweight in children, the level of cholesterol tends to increase, as a result of which children tend to be least active. 

Therefore, it can also be the cause of bad performing at school because the more they are less active, the more things get more challenging for them. So, being less active or lazy, they can not learn things quickly at school, and they get worse at school performance.
