Cold and Hungry

[Zen]

This is interesting and explains a lot...

Ever feel like you’re more famished after a long ride on a cold morning than if you did the same workout during the heat of the day? Do short swimming workouts leave you hungrier than a long run in the heat? Well, it turns out there’s a scientific explanation to your cold hunger.

I actually experienced this during Saturday's very hot Civil War Century in a major way:
From that link:

Did you know? The opposite response happens during exercise in hot weather. Instead of feeling like you can scarf down a Thanksgiving turkey, you’ll probably have little or no appetite at all. That’s because the body is doing everything it can to cool down and eating food, thus generating heat, is not on the immediate agenda. However, it’s times like this that you must eat to quickly restore your glycogen, a.k.a. fuel stores, in order to keep your energy levels up and recover.

By the 3rd rest stop, I was sucking salt off peanuts, rather than eating them. The 4th rest stop is "famous" for it's tomato sandwiches. I couldn't even look at them (might have been the mayo, too, oozing out of them. Blech).

I read somewhere (wish I could remember where) that you don't actually burn more calories during a cold workout vs. a hot workout, and that people use their feelings of hunger after a cold workout to overeat (alluded to with the swimmers in the link).
