Just a reminder, I still adhere to the belief that the phrase “scientific study” should be given equal weight with the phrase “movie review”. This is because there is a whole lot of experiment free research being presented as science. With this caveat, the following work of statistical data analysis finds some unconventional wisdom.
The Weight Story No One Wants to Talk About: But in contrast to the cancer report, which received enormous and largely uncritical media attention, a new study about obesity by Katherine Flegal and colleagues from the Centers for Disease Control and the National Cancer Institute made few waves. Yet Flegal's quiet and careful study could do much to calm our growing national hysteria about obesity.
Flegal used data from the National Health and Nutrition Examination Survey, which is a representative sample of the US population, to find the connections between being underweight, overweight and obese and cardiovascular disease (CVD), cancer and many other causes of death. The results are startling since they confound much of the received wisdom about being fat in America.
Flegal discovered that being overweight (BMI's of 25-30) was not responsible for increased mortality. In fact for CVD, cancer and all other causes, being overweight actually increased one's chance of living longer. In total, overweight was associated with a total of 138, 281 fewer deaths. Being overweight is not likely to kill you.
