during cold weather does your body burn calories at a quicker rate to keep itself at 98.6? this would make sense to me, that the body would require more calories in order to maintain temperature.....


if this is the case, exercising in the cold may be more efficient in losing fat than in the heat?????...........just a thought

A drop in body temperature can stimulate the appetite and thus hunger. On this note, if you become chilled during winter exercise you'll likely find yourself searching for food. Eating stokes the furnace so to speak, and thusgenerates heat, and helps warm your body.

Food's overall warming effect is thermogenesis. Thirty to sixty minutes after you eat, your body generates about 10% more heat than when you have an empty stomach. This increased metabolism stems primarily from energy released during digestion. So, eating not only provides fuel but also increases heat production, warmth.


On that note, I found this question asked a long time ago somewhere


Do I burn more calories when I exercise in the cold?

Cold weather itself does not increase calorie needs. You don't burn
extra calories unless your body temperature drops and you start to
shiver. (And remember: the weather can actually be tropical inside your
exercise outfit.) Your body does use a considerable amount of energy to
warm and humidify the air you breathe when you exercise in the cold. For
example, if you were to burn 600 calories while cross-country skiing for
an hour in 0 F weather, you may use about 23 percent of those calories
to warm the inspired air. In summer, you would have dissipated this heat
via sweat. In winter, you sweat less.

If you are wearing heavy clothes, you will burn a few more calories to
carry the extra weight of skis, boots, heavy parka, snow shoes. The Army
allows 10% more calories for the heavily clad troops who exercise in the
cold. But the weight of extra clothing on, let's say, winter runners is
generally minimal...

so it is your opinion that cold weather increases metabolism?





and that your body burns more calories during winter exercise because it needs to warm the cold air?........

The body will use more calories to maintain it's body temperature, thus you'll burn more calories in cold weather than warm. However, you probably won't be naked in the snow exercising. You'll have warmer clothes which retain expended body heat. So it's usually not an issue.


There was a debate a while back regarding the temperature of water you should drink. The debate was if the water was chilled to a certain temp, it would lower your core temperature and make you burn more calories. It made such a tiny difference that we all agreed it didn't matter.

Nice post Showdown. I remember, it was the site, howthingswork.com I believe that had that info on it everyone was quoting.


In response,to the question, yes, cold weather will. But it is will be inconsequential in the scheme of things.
