“You have to ask yourself this question, how many fat people do you see who are 70 years old or more?”
Not SO many, but I wonder -
is it because most of the fat people die before 70? OR
is it because people start to lose their appetite in the 60s and start to dwindle?
My MIL was very heavy, 300 plus, for a couple of decades. She did WW, Jenny Craig, Nutrisystem. . .not much success. However, about five years ago, she start to eat less. She just wasn’t very hungry. She sees a doctor regularly - doesn’t have cancer or whatever. She is just not as hungry any more, and has lost over 100 pounds. And boy is she sedentary!
Probably a combination of both.
