re: Why are people so fat now compared to just 30 years ago?

Although diet and exercise are huge factors and play into this, it’s also public perception of what is fat is changing by the decade. So many people don’t realize just how fat they are. They keep gaining more and more but they think “I just to lose like 10-15 pounds and I’ll be good”. Obviously this doesn’t apply to the people who are very obese

At one point x pounds over normal weight is seen as fat by the majority of people. But as people becoming fatter, that number seems normal now since it applies to so many people. A decade later 10 more pounds of whatever number that x was, is now considered fat. Until more people ballon up to that. And so on...
