Thanks for posting this Hal. I haven't checked out all the comments it has
provoked, but I have some initial thoughts:
Previous results like this have been critiqued (or qualified) on the basis
that the very low-BMI group includes many seriously ill people in hospital
who cannot keep weight on. That's not remotely comparable to healthy lean
people. I'd like to know whether these researchers analyzed that effect and
separated it out.
Also, I find the BMI number quite dubious. Anyone with a reasonable amount
of muscle on them will come out as overweight, even if their bodyfat
percentage is well below average (say 10%). A number that doesn't allow for
differences in body composition seems to be a poor basis for making judgments.
For the record, I'm not a big fan of major caloric restriction for several
reasons, though mild restriction seems sensible to me.
