I understand that Metabolism is the rate of calories used to sustain our bodies. I understand that we eat and exercise in ways to maintain a high level of metabolism.

We often speak of burning calories. I believe that when we use calories, heat is produced. When we exercise, heat is produced. Is the heat it self beneficial in fat loss? Thus, if we were to wear tons of extra clothes or turn the heat up in the house, could we effectively increase fat burn? Or would the exact opposite be true, that if we go extremely cool, would our body fight that and burn more calories in an attempt to maintain core temperature.
