Step-by-step explanation:
Childhood obesity is caused by a combination of factors, including excessive food intake, inadequate physical activity, and genetic susceptibility. In addition to these factors, socioeconomic status and the physical environment also play a role.

Some children may also be influenced by the availability and affordability of unhealthy fast food options.
