Because it’s been studied and found that even controlling for all the factors we understand and can test for, being overweight makes you more likely to get sick and die.

The exact mechanisms through which it causes you to get sick and die aren’t fully understood, but we know they exist because of many overweight people, whose test come back otherwise healthy, getting sick and dying.
