I have been reading a study arguing that people are more predisposed to obesity if they have fat friends, being a factor more important than genetic predisposition. I can't find the link right now.

Also, more and more people are getting fatter / obese every day. Clearly genetic predisposition can't explain this problem for such a large scale in such a small amount of time ... so this is in fact a social problem that grows by network effects.

So whether it is our lifestyle, or our diet, it's clearly spreading. Therefore I don't think it's a stretch to call it an epidemic.
