Its about "the limit of human adaptation to starvation"
http://www.validinternational.org/tbx/docs/ACF3931.pdf
(it's somewhat long/there are graphs)
I think it brings up some good points about the limits of using bmi to assess the level of starvation. Also brings up points about how the climate and body type may allow for lower bmi.
I don't have any particular discussion. I just want to see what others think. Could these studies be useful in researching anorexia or are they pretty irrelevant. I will delete this in a heartbeat if asked.
