you burn a higher PERCENTAGE of fat to glucose at that level, but at
higher intensities you burn more overall calories.

That's right. I read a good post from Lyle MacDonald once that addressed
this subject. Maybe Huey could find it by doing a Google search. At any
rate, he pretty much shot out of the water the concept of exercising at
certain rates in order to "burn more fat".

True that you burn different proportions of fat to glucose depending on
various factors including exercise intensity and duration, but the bottom
line is to use up energy (calories) via any permutation of exercise in order
to hopefully create or increase a negative calorie balance. That's what
actually causes fat loss over a period of days, weeks etc. In other words,
burn more calories and you'll lose more fat, assuming food intake stays the
same.

Besides which, if you're doing a ketogenic low-carb diet, you don't have all
that much stored glucose anyhow and will be burning mostly fat regardless of
intensity.

At higher intensities you have to be careful of
overtraining--especially on a ketogenic diet. Sometimes it is best to
back off the intensity. You have to listen to your body. It's not
always best to go as hard as you can all the time.
