My sibling, who has an addictive personality trait, required bariatric surgery after attempting for years to lose the weight (~120lbs overweight). Their doctor told them if they didn't lose the weight, it was going to kill them. Post surgery, they are in the best shape of their life. Insurance covered it, because they demonstrated they attempted all other options first. They simply can no longer overeat now due to the plumbing update.
But sure, laziness. Feelings over data. Shockingly common.
(these drugs were in clinical trials at the time their surgery was scheduled, and were inaccessible to them)
