Christie is borderline morbidly obese. He has a greater than 50-50 chance of dying of a heart attack or stroke. So it’s not about looks. (But I guess a super-fat guy is real “authentic” or something, so there’s that.)
I have to disagree with you. Gov. Christie is certainly morbidly obese. He's huge. I'm not making any opinion on his policy, but as someone said, "he needs to lose 100 pounds", but that just gets him to borderline IMHO. From the pics I have seen, 200 pounds + would be closer to the mark.
Cleveland and Taft were as big and they both lived to be older than 65. Long-lived for their times. TR, whom so many associate with “vigor,” was also hefty. JFK, by contrast, was a medical “mess.” probably the most unhealthy man ever to be elected President, even though he looked good.
