Subject: Can a 'fat' person survive longer without eating than a skinny person?

  For example if a fat persong were to go without food (but plenty of 
water) would he survive until he ran out of energy (fat) reserves.  What 
would be the ultimate cause of death in this situation?  (is it a lack of 
energy to keep the heart going?)  I am not talking about chronic 
starvation and malnourshiment - more like a healthy person in a survival 
situation.  It seems to me that the fat person might live a little longer, 
but that they could not for some reason completely/instantly switch to 
complete reliance on fat reserves?)
