What percentage of humans would you estimate being fat is "natural" for?  There are many former fats on this site who would disagree with you.  How do you account for the fact that looking at photographs of humans from just 30 or 40 years ago, there were very few fat people compared to now?  What changed in human DNA within 1 generation?  It is obvious to me that the vast majority of humans are not naturally overweight, just as obvious as it is to me that the world is not flat.    I would concede that perhaps maybe 2% of humans might have some genetic abnormality that might make them naturally obese. I'm seriously asking because you claim to be an educated person but what you are saying is insane to me.  I'm legitimately curious.
