being fat, another thing that you can no longer be judgmental about

Apparently how fat you are isn't just a matter of eating too many donuts and sitting too long on the couch. Scientists have found obese people have a different bacteria in the intestines than the rest of us. They're not sure why, but apparently switching bacteria in mice affects their weight. So have another twinkie and tell folks, it's not the twinkie, it's just my bacteria. Because that might actually be the case.
