If one looks around during events, s/he immediately notices that people are too fat. There is a measure of how much they may weigh too much, called Body Mass Index
Not all countries have the same eating habits, but the ones that have abundant food. over-eat and under-exercise. Over-eating in the United States was proven by research by Brian Wansink. His research was compelling (if memory serves we bought his book during a Cornell reunion), the Wall Street Journal referenced him saying that overweight waiters may inspire restaurant customers to eat and drink more. Unfortunately, Wansink was cheating on his research to make it more newsworthy. The Wall Street Journal’s OVERHEAD column did some pizza research that showed the largest pizza-makers sold a lot more during the COVID. But there is also the good news that scientists found that the coronavirus attacks fat tissue. And you are not alone.
