Big Fat Truth

 Interesting article from Nature on the 'Obesity-Paradox',
  • A team led by Katherine Flegal, an epidemiologist at the National Center for Health Statistics in Hyattsville, Maryland, reported that people deemed 'overweight' by international standards were 6% less likely to die than were those of 'normal' weight over the same time period.
The principle gap I can see is that there was no account for body-composition.  This point is alluded to in the final paragraphs,
  • All this suggests that BMI is a crude measure for evaluating the health of individuals. Some researchers contend that what really matters is the distribution of fat tissue on the body, with excess abdominal fat being most dangerous; others say that cardiovascular fitness predicts mortality regardless of BMI or abdominal fat.
  Thought provoking all the same.
