All of us here at Power Cordz are obsessed with performance. Not only are we proud to make the lightest bicycle control cables in the world, we are also concerned with every other aspect of cycling. Which got us thinking about the most important part of a bike, its rider. When we take in calories, we don't always use all the ones eat. We all know that these unused calories turn into fat, and when you haven't used 3,500 of them, you tack on a pound of fat to your body. But what happens when we tap into these energy reserves on a hard day?
If you were to ask most people what happens when someone losses a pound of fat, the answer is most often that it turns into heat, but that is definitely not the case. The Law of Conservation of Mass, makes it impossible to turn matter (fat) into energy (heat). So what really happens to it?
When you "burn" a molecule of body fat, it takes 78 molecules of Oxygen and through a fairly complex set of bio-chemical processes, your body turns it into 55 molecules of Carbon Dioxide, and 52 Molecules of water.
That's cool but where does the weight go?
84% of a pound of body is turned into Carbon Dioxide the other
16% is turned into water.
So most of the weight you lose, up to 88% is exhaled, the rest you sweat out.
I'd bet that's not what you were thinking, was it?
