This may or may not be true (and I'm certainly not interested in having a flame war on the topic here), but given my inherent cynicism, and the state of science, particularly government-linked science, in the US at the moment, I can't help but wonder if either the research or the CDC itself are currently sponsored by McDonalds...
Correct me if I'm wrong, but to my reading the article appeared to be saying that being overweight increases you risk of dying from X and Y, but doesn't increase your risk of dying from A through W.
And this is news because...?
Well, first off, that's a misleading headline, and a bad article to boot...they're not saying it's ok to be fat (i.e. obese). Weighing 350 pounds still puts you at risk of lots and lots of stuff across the board (unless you happen to be 7' tall) and they're not recommending you suck down jars of lard.
The observation is that people who are mildly to moderately overweight (less than 30 pounds over the weight dictated by the "recommended" BMI) have a decreased risk of death from some diseases that is not outweighed by the increased risk in death by other diseases.
Since BMI is a bogus measurement anyway, this is not surprising. I won't speculate on why this could be since I have no idea, though I'll suggest that if you get sick for more than a brief period of time, having a few extra pounds of stored energy may be beneficial in helping the body to fight it. There's a reason that plump used to be considered beautiful.
Or, maybe you could just take this chance to try for a cheap dig at the US/your favorite multinational to bitch about, instead of actually thinking about whether this study argues for causation or just notes an observed correlation.
