Hungrier? Exercising in much colder temperatures

[shootingstar]

This is hiking and cycling just within my own home city. I tend to eat much larger breakfasts with egg, etc..when away from home and going snowshoeing in the mountains.

Well, I certainly forgot to bring some food. (which again for this small distance on bike in summer, fall, I don't bother.)

I did notice for myself, that when I did eat a large breakfast at the hotel. Then off snowshoeing for 2 hrs. in the mountains, I did feel appropriately....."empty" at the end of the trip, without being hungry.

People living in our area.....go 1,000 km. north to work in the winter, at the oil tar sands and oil rigs near Canada's Arctic Circle. Just to give people an idea here, how "tough" locals can be...and their willingness to work under such conditions outdoors in the winter. So the coldness in our area, is like practice for them... I continue to be amazed to see how thinly dressed some cyclists and joggers are. In my head I'm thinking: They must be born in this area...not a transplant like me.

When I cycle in winter @ -10 to -20 degrees C, I am definitely cycling alot slower --at least 25% slower. There's no real reason to cycle fast in such cold wintery temperatures. So definitely I am not sweating it up like some joggers or cross-country skiers and expending alot of calories every half hr.
