As I understand the Krebs Cycle to work, yes, that is correct. (If this is reference to the Seebohar questions from earlier last week, then I would also add that in the webinar I listened to with him he never advocated a completely carb free training.)

If it is not, then forget I said that, but nevertheless.....
I have his book here at the house and he gives out information on how to calculate the body's needs of carb/protein/fats. He never says to avoid carbohydrates, simply to choose the timing carefully and thoughtfully. Fat will break down into components that produce glucose for use by the body. He talks about glucogenesis in the book as well. What he does advocate is to change the way you mix those macronutrients during specific periods in training (base, build, etc.) to help with performance and weight loss.

I don't know that I would train his way 100%, but he does have some interesting points and for someone with diagnosed hypoglycemia, it has worked well for me to look at the concepts and apply what I can. I have managed to drop 10 lbs off my frame (5'9", 134 now) and am shooting for those last 4 for race season.

I think of it the other way around. Burn carbs in a fat fire. Look at fat as coal. Look at carbs as newspaper. What burns faster and gives off a ton of heat? Carbs do. So if you can train your system to burn a lot of fat and the coal gets going, it will act as a bed of coals to ignite whatever newspaper (carbs) you throw on the fire. Yes, adding carbs to your long and/or high intensity workouts and races is paramount for continued performance above your threshold for a long time. One you burn through your glycogen stores your body wants fast sugar, not slowly converting fat, to keep going. If its not there?....Welcome to Bonktown.

with training, the body will become more efficient at burning fat. and in my opinion, it's never a great idea to train glycogen depleted.

there's no need to "force" the body to burn fat. it'll do it on its own when it needs to and when the duration/intensity of exercise allows it to.

i'm not sure why creatine is mentioned. phosphocreatine (PCr) is used up very quickly during high intensity exercise and is long depleted before any run becomes a 'long' one.

fat's broken down through b-oxidation which produces the acetyl CoA to be sent to the CAC and further, the ETC for complete oxidation. it is physically impossible to strictly burn fat during a workout. you are ALWAYS burning CHO to some degree, whether it be from exogenous CHO, glycogen, or gluconeogenesis.

the bottom line is, you want to spare endogenous glycogen as much as possible, esp for longer workouts lasting over an hour and this is obviosuly done through CHO supplementation. I don't believe it's necessary in the least to nutritionally deprive yourself for a workout thinking your body will then become 'better' at burning fat. the body becomes more efficient through capillary network expansion, mitochondria size and number increases, type I fiber expansion (which encompasses the capillary/mitochondrial changes), etc.

give your body the energy for what you demand of it, and it'll take care of the rest.

Here....fun watching and hey, there is a quiz :)

in the morning, before breakfast, your body has ~90 minutes of stored glycogen.

so, attempting to micromanage your body composition in this particular manner wont work.

Jack, studies show that working out before breakfast early in the morning burns more fat than eating first.

I don't know why, it could be that by preventing an insulin response, you're burning more fat. But either way, it's true.

Now, as to the tom-foolery of trying to "train" your body to burn fat, etc. is all hooey in my opinion.

I can believe that, but then at the end of the week, your caloric balance is what it is

however, burning more fat doesn't necessarily equal an increase in performance. which, ultimately, is what is trying to be acheived (well, for those in training).

i would argue it may actually detrimental to performance increases.

it's not as simple as calories in vs. calories out.
