Are you asking what the root cause of obesity is? It's eating too much and not exercising enough. It's not some mystery. Or is the question about why people behave in this self-destructive way? People on average are bad at impulse control. Snack companies take advantage. People feel varying levels of discomfort vs exhilaration when exercising. For some it ultimately feels nice, for some it is unpleasant. Of those for whom it is unpleasant only some have the forethought and leeway to establish and maintain a healthy lifestyle. Of those for whom it is pleasant some face time or schedueling contraints that make an active lifestyle difficult. If there's a root cause to be fixed its that the human body responds poorly to acting on its impulses in our current built environment. You can solve that by altering the environment, the body, or the impulses. Ozempic seems to work by altering the impulses.
