It seems to me that here, in the US, more people are much fatter than they were 20 or 30 years ago. The US military has found that recent recruits are fatter and in worse shape than ever before, and this is considered a "threat to national security," believe it or not. I remember in the 60's and 70's, obese people were rare, and, indeed, a curiosity.
Now, I see morbidly obese people every day. My experience may be anecdotal, but it comports with my wife's experience, and she's been a physician for more than 30 years.
The other thing to keep in mind is the food supply. Most of our food has additives in it that either directly causes obesity or indirectly causes it through messing up the body's hormones. I have had doctors think it's amazing that I'm not a size 24 with the fact that I have both Polycystic Ovarian Syndrome and hypothyroidism. Granted, I have recently lost a lot of weight (through odd means at that) but I'm still not as small as I should be. I should probably be a size 8-12 instead of a 12-16, even though I am larger built in my rib cage than most women of my height.
Could it be that your perception has changed? Since health officials and the media have touted the dangers of obesity and the epidemic "explosion" you're now more aware and concious of fat people, obesity becomes something significant in your perception.
For example if there was a sudden barrage of media reports that red hair was a severe health risk and that it is spreading at an explosive rate and that it could be spread by social networks, all of a sudden I would see redheads everywhere all of a sudden something I've always ignored or not noticed becomes significant. If something is on your mind the more you'll notice it.
It's true that say in the very highest bmi categories (the top 1 or 2 % of people) there has been quite a big increase, but this is still a very small group of people. The exaggeration comes into play when health officials/the media use this very extreme and tiny minority as typical of the all people that have a BMI over 30 (1/3 of the population).
Because fatness is a continous trait that is measured by a fixed threshold (bmi 30+) and that trait is normally distributed, the obesity epidemic could be reversed overnight by all the people with a bmi just over 30 losing a few pounds to get to BMI of 29.9.
The fact that a BMI of 29.9 counts as not obese and a BMI of 30 does count as obese has been widely abused and has led to a lot of inaccurate conclusions.
It's interesting that another link on the same site says they're on the rise:
