Subject: Fuel wise speaking, who would walk further a skinny person or a fat person

I loved your answer about who suvives longer a skinny person or a fat person. 
Would the same be right if they would starve and walk at the same time? Would 
not the fat person draw more energy from his or hers fat reserves? Would 
coniunes movement prolong the live of the fat person or would it just speed up 
the breakdown of protein and they both die i about the same time again.

And how does the liver create Glucose out of fatyacid and how does it convert 
Lactate into glucose?

Thanks a bunch all this talk about food is making me hungry.

Hope this question makes.
