Causes of Death Linked To Weight
An anonymous reader writes to mention that while a couple of years ago researchers found that overweight people have a lower death rate than people with a normal weight, it may be more complicated than that. "Now, investigating further, they found out which diseases are more likely to lead to death in each weight group. Linking, for the first time, causes of death to specific weights, they report that overweight people have a lower death rate because they are much less likely to die from a grab bag of diseases that includes Alzheimer's and Parkinson's, infections and lung disease. And that lower risk is not counteracted by increased risks of dying from any other disease, including cancer, diabetes or heart disease."
BMI combined with a shred of common sense is a perfectly fine approximation of obesity.
Maybe it's common sense that needs to be taught in schools then.
Seriously, now we're going to have to deal with a bunch of obese people pointing to this study as evidence of why they don't feel a need to lose weight.
Something's obviously missing in this study, because there is a positive correlation between average lifespan and obesity rates, both when comparing countries around the world and when comparing historical rates within this country. The simple fact is that all else being equal, the fatter a population is, the shorter its average lifespan. The United States, for example, ranks 42nd in world life expectancy - Japan, with much lower rates obesity and average weight, ranks #2. (Behind Andorra.)
Not to even mention other studies (like this one, for example) that show that being even moderately overweight can increase your risk of heart disease by more than 30% - and that's our nation's #1 killer. That's to say nothing of diabetes.
I'll take my chances on being thin, thanks. One study that appears to contradict all scientific knowledge we've accumulated to this point isn't going to change my mind.
