Fat people are unhealthy

It would probably surprise most people to hear that there
is a great deal of debate among researchers regarding this contention
Some feel the health risks of obesity have been exaggerated.
Will weight loss improve your health? The jury is still out, but
here are two conclusions from a 1992 National institutes of Health
conference on obesity:

• Although there seems to be little doubt that overweight
  individuals have increased risk for morbidity and mortality, it
  does not immediately follow that weight loss reduces the
  increased risk [Some studies indicate that intentional weight
  loss (rather than weight lost due to illness) is associated
  with increased mortality].

• Given the high likelihood that weight will be regained, it remains
  to be determined whether these time-limited improvements
  confer more permanent health benefits.
