Yep. You had mentioned it several times in another context, and I

Understood!

Ok, thanks.
The big picture of where I'm coming from is I had seen some information
in an Iditarod training handbook - late 80s, but by university professor
and with some citations, so tend to think of it as science rather than
old wives' tales. I recognize that's not foolproof and was trying to
verify whether some of the things he stated were real or old wives'
tales that were being propogated because researchers hadn't tested the
hypotheses yet. Some were consistent with what I'd been taught; some
were not. I'm just looking at hydration / fuel / warmth issues for cold
weather (+10F and below) activities like running and xc skiing for
multiple hours. Above +10F, the issues don't seem to be as significant -
or I've figured out how to deal with them, but this seems to correspond
to temperature when some other things start happening or become more
significant.
Some of the tidbits were
1. Energy sources switch more toward fat in cold weather, and this is
consistent with past experience.
2. Shivering is anaerobic and uses glycogen.
3. I think women are supposed to burn more fat than men in cold temps.
4. Water loss through breathing will involve more from the lungs because
of the low humidity of cold air. (Electrolyte loss was never mentioned
in this context).
If a person burns more fat in cold, then something like Clip 2 (has fat)
might make more sense than Ultra or Cytomax. Clip 2 has no electrolytes
since it's designed to be used with electrolyte tablets or other source
of electrolytes so you can get right water/salt ratio for your own
conditions. Trying to deal with tiny tablets can be a challenge with
mittens in cold temperatures. If a lot of the moisture was coming from
the lungs, I was thinking that might reduce the need for electrolytes,
but apparently not from Tom's post. Salty snacks plus Clip 2 might be an
easier way to deal with it, if it needs to be dealt with.
I can use all 3 of these drinks although I prefer Ultra and Clip for
stuff over a couple hours because of their light flavoring. And I will
test to find what works for me. It's just that understanding the
physiology better can help make more meaningful tests.
There really is a running-related reason for my curiosity.
Thanks. Happy Holidays!
