The following is quoted from
http://www.mercola.com/2005/jun/9/fatburn.htm and is from Ron Rosedale.
I thought it was interesting because Rosedale makes the point that the
fact that we burn sugar first does not entail that sugar is the
"preferred" fuel.

"You store fat -- and, in many people, lots of it -- in your "cupboard"
and not very much sugar, because fat is the fuel that your body would
prefer to store and later to burn to stay healthy.

However, when you eat sugar and fat together, your body will burn sugar
first. I believe that it burns the sugar off because that is one way to
get rid of it. Sugar causes damage by glycosylation and having it around
too long is extremely damaging and accelerates aging.

Therefore, your body might get rid of sugar to minimize the damage
caused by keeping it around. You'll have to burn off almost all the
sugar that you eat before you can start burning fat and, in most cases,
that means that the fat you have eaten with sugar gets stored. Your body
continues to become adapted to burning sugar and not fat.

People get fat not so much because they eat fat, but because they have
forgotten how to burn it, and because of poor hormonal communication."

Finally, I was struck by the following assertion.  I don't remember if
it made it into his book or not, but it sums up what I have come to
believe about nutrition and health.

"I have been asked to summarize in a single sentence what would best
promote health. It is this: Health and lifespan is determined by the
proportion of fat versus sugar people burn throughout their lifetime.
The more fat that one burns as fuel, the healthier the person will be,
and the more likely they will live a long time. The more sugar a person
burns, the more disease ridden and the shorter a lifespan a person is
likely to have."
