It's actually very simple to do your own research on this. Ask yourself: How many people >85 y/o have I known who were obese? How many normal weight or thin?

We don' need no steenkin' study...

“We don’ need no steenkin’ study... “

Yup.
Yet another waste of tax payer money to do “research” to “confirm” what everyone knows already.
Where else do we spend billions of dollars svery year on weight loss programs?

Could that as well be reverse causality? There may be any number of reasons a person wouldn't or couldn't eat as much when old as when younger.
