Morbid obesity is a choice... depending on who you talk to. I don't know about obesity. How much is caused by genetics for some, environment for others, sheer laziness for others.
Calling it a choice is cruel. We're ruled by a whole host of genetically programmed behaviours. An extremely strong one is culture. If you live in an environment where you are surrounded by people with bad eating habits you are much more likely to also start eating badly. These are very strong pre-programmed behaviour patterns. If the "choice" is between following what your instincts tell you or to be unhappy, it's not really a choice. We, in the free and liberal west, commonly live in the illusion that all humans are free agents who can freely chose between rational choices. Well... pretty much any research into any human behaviour tells us that virtually all people mostly do dumb irrational shit. Most of it is geared toward eating, conserving energy, fucking or triggering other cheap dopamine responses.
Overweight is the result of a whole system of behaviours calibrated to fit a certain lifestyle. They get created over a long time, and they take years of systematic work to break. Any human habit is the same in that regard. But food is one of the hardest. If you were lucky to have been given healthy habits early on, it's just luck. Just like a person who has grown up in a family of successful entrepreneurs is more likely to, themselves, become a successful entrepreneur. It's an entire system of patterns all re-enforcing one another.
In almost none of the cases of over-weight is it down to diseases. It's nearly always culture. Unless depression counts as a disease. A very common cause of obesity.
