It is clear that the cause of obesity is a result of eating more than you burn. It is physics. What is more complex to answer is why some people eat more than others?
Differences in our genetic make-up mean some of us are slightly more hungry all the time and so eat more than others. In contrast to the prevailing view, obesity is not a choice. People who are obese are not bad or lazy; rather, they are fighting their biology.
