So what is a calorie?

We see this little word all the time but do we really know what it means.

Actually a calorie is a unit of energy measurement. The definition is - A unit of energy defined as that amount of energy required to raise the temperature of one gram of water by one degree Celsius ...
Essentially it is a unit of heat. So when you see a burger and it has 400 calories it means that there is enough energy present in the burger to raise the temperature of 400 grams of water 1 degree Celsius.

In the past whenever I got sick and ran a fever for any length of time I always felt "thin" afterwards. There was a very good reason for this.

If I weigh 260 pounds, which I do, and I run a fever of 100.4DegF.
This raises my body temperature by 1 Degree Celsius. This takes a tremendous expenditure of energy. (keep in mind a 260 pound person has about 114,000 grams of water) If you run a fever for any length of time I am pretty sure that it is the equivalent of strenuous exercise the entire time you are running a fever. ( If anyone has the exact calculation for this let me know)

So that brings me around to my main point. When you lose weight where does it go? Quite simply you lose it in the form of heat. Anything you can do to get your body to generate heat will make you burn calories.

Exercise is the most common way to do this. When you run you sweat and you sweat because you are producing heat. It's that simple.

The Tabata protocol makes you produce heat all day. Trust me, when I do the Tabata workout I sweat for two hours after I am done. For the rest of the day my skin feels like I am running a fever. It is pretty remarkable. Time will tell how well this is going to work!
