 Oh, forgot to add in the last post--yes, I mentioned that their consumption 
of energy is pretty much the same in my post to which that was a response.  
It is the GI physiology which differs so much from species to species.

And GI function has nothing to do with energy metabolism, which is the 
subject at hand. The questin is, given a choice, which source of energy will 
muscle use first and foremost--and to the exclusion of other forms of 
substrate? The answer is..., well, you already know. The second question is, 
given no choice, which energy source is vital? The answer is the same.  So, 
is it not logical to ensure that there is an abundance of the preferred, and 
vital, substrate????
