Classification is subject to change because science is an evolving subject. New things are discovered every year and thus changing the way we understand the world around us.
Answer:
Obese
Explanation:
Obesity can occur at any age but in recent times more and more children are becoming obese. They develop an unhealthy relationship with food from a young age. Food rather than being a source of nutrition becomes just a source of sensory stimulation.
These children often chew very fast and swallow food without properly breaking it down. Thus they are not able to realize when they are full. They ignore the internal cues for hunger or fullness and keep eating to satisfy their palate. As a result, they become obese.
Metabolic pathways stimulate cell division.
