Potassium is excreted in perspiration, so it might be useful to supplement

with some. How much, and in what form? I don't know. I've intermittently

taken a couple hundred mg in SSKI form lately, but that's obviously not a

supplement that can be taken long-term. Potassium citrate is evidently

quite hard on the gut, and I'm leery of citrate forms of anything

anyway. So the only answer I can really offer is who knows?

I don't know. I would think that it would be impossible to fully

adapt this way, just due to the nature of fat storage and glycogen

storage and how quickly it is available. However, I would think it

might be possible to adapt to turning the fat into glycogen, although

that might be enzymatically stressful.

My knowledge of these metabolic pathways is admittedly somewhat sketchy,

but it seems to me that the body could adapt fairly readily (particularly

with adequate carnitine) to producing adequate energy by burning fat

directly. MCTs in particular are supposed to provide a rapid energy surge.

In that case MCTs do not require carnitine, which is only necessary

for long-chain fatty acid oxidation.

I don't know. I really haven't studied the issue so I'm just throwing

guesses out. But isn't glycogen more intimately integrated into the

muscle cell? Compare that, for example, to mobilizing fat stored in

adipose tissue...

True, but my speculation is that people notice such dramatic effects from

MCT at least partly because in general their ability to burn fat has been

so dramatically compromised by poor diet and malnutrition.

I don't know for sure, but I've often seen it asserted that 70% of muscle

energy production comes from burning fat, and since some of Price's healthy

natives ate extremely low-carb diets and yet had outstanding athletic

ability, I'm very skeptical of the notion that glycogen -- and by extension

substantial dietary carbs -- are necessary for lifting weights.
