Nowadays more and more people are obsessed with obesity, and they have tried in many ways to lose weight but got few result due to an unclear understanding of the factors that are responsible for obesity. In my opinion, three factors may lead to this phenomenon. Part of the explanation for it is the genetic inheritance. Some people are born bigger and fatter because they have inherited some piece of gene which decides their obese figure from their parents. But their parents are not necessarily fat, because the gene in them may not be dominant. So it seems that people are obese due to the genes can’t change their situation unless they receive some operation to utter their genes.本回答被网友采纳
