Nobody has the guts to mention the big fat stinking elephant in the room. Obesity if the direct result of a moral failing. That moral failing is called gluttony. A lot of people will call gluttony food addiction and from a neurological perspective they would have an argument albeit a weak one.
On the left we see a brain scan of a normal person and on the right we see the brain of a glutton, Gluttons are not born with dissimilar brains, their gluttony changes their brains.

Food preference first develops in the womb. Studies show that if moms drink carrot juice during pregnancy, infants are more likely to prefer the flavor of carrots. To see if this holds true for less healthy foods and to probe what’s going on in the brain, researchers turned to monkey studies.
While pregnant, monkey mothers ate either a healthy, low-fat diet or a high-fat one. When their offspring were young — equivalent to human toddlers — they were given access to a junk food diet, high in fat and sugar. Compared to monkeys whose mothers ate healthy diets during pregnancy, monkeys whose mothers ate high-fat diets consumed more of the junk food. To see how their prenatal diet had changed their brains and possibly permanently sculpted their food preferences, the researchers looked at the expression of dopamine markers in the brain. Dopamine is a neurotransmitter important for reward and motivation.
