Defects in the single genes like leptin, leptin receptor, and melanocortin four receptor which play a major role in the appetite regulation can lead to obesity at a very young age.” These defects can be passed onto the next generations. “Also the change in the genetic make up of the gut flora that plays a major role in the digestion process can cause child obesity” (Heit). “Because of the presence of the susceptible genes in the genetic make up of the child, these genes cover large areas of the chromatin and are passed on to the kids from their parents”(Heit). Heit goes on to say that even though there are no cures for genetic factors that causes obesity, the best solution is to try to prevent obesity by dieting, exercising, and having regular check ups.
