If you really want to see how bad fatness is, watch an ER team try to resuscitate morbidly obese people.

They can't do chest compressions because they can't get to the heart from the fatness.

They will literally cut open your chest, mount the fucking OR table, reach into the incision area, put their whole ass arm into it, reach under your ribs, and physically grab the heart and massage it to make it beat.

That is typically how you are going to die if you are that fat because that is standard CPR policy unless you have a DNR, and you are seriously overweight. And normally, it won't work because of all the damage to your circulatory system already.
