Large type did not show up. Good.
this is the url I have been using
I did not know wikipedia was so extensive.
It even tells you why metabolism and why the OP's question is of interest
and controversial.
So I am glad I brough metabolism into the equation and I hope you will be
also.
http://en.wikipedia.org/wiki/Basal_metabolic_rate#Cardiovascular_implications
and as a reminder
http://www.bmi-calculator.net/bmr-calculator/
and all it's links that are relevant.
Hope it helps.
