There is no doubt there is a genetic link for certain people with obesity. The latest study looking at such a connection was conducted at the University Buffalo. What they found is people who genetically had a lower level of the brain chemical dopamine might be driven to eat more food. People who have fewer of the dopamine receptors need to take in more of a rewarding substance, such as food or drugs, to get an effect than other people with less. Now, the report does not mean if you have the genetic makeup that you are doomed to be obese, but it is clear there is a relationship. Naturally, much of this work is done because scientists are looking for ways to help offset obesity.
