Hi Jim, 
Because burning fats causes less CO2 production at the cellular level there
is less CO2 to exchange across the lung mucosa.  I have a lung disease that
causes diffuse scar tissue on my lung walls (smokers get patchy scar
tissue). I find that when I am in ketosis my lungs function a lot better. My
peak flows are higher and I rebound more quickly from breathlessness when in
ketosis. If I stay in ketosis for a few weeks I drop about 10 pounds which
probably gives my lungs a little more expansion room too.

Best Wishes,
Ron

Nothing helps keep the nose clear and breathing easy more than low carb. The
lower the better.

You've said that several times, Tom.  I wonder why that would be so?  There
are two major health benefits with the paleo diet, one having to do with
keeping insulin levels low and the other having to do with avoidance of
foreign substances.  The latter absolutely would help keep the old sniffer
clear.  But I've never heard that low carb does the same thing.
Interesting.
