How does fat leave the body?

 Q: How does fat leave the body?

A:  *Actually, your fat cells stay right where they are. What is happening is the contents of the fat cells are released, in the form of free fatty acids (ffas). These ffas are then converted and used for energy by your body.

The energy that goes into the biological system known as “the body” is measured in calories that are derived from macro-nutrients that make up food.  This “chemical” energy derived from food is then utilized to be transferred into other required forms of energy to accomplish physiological processes in the body, as well as produce body movement (mechanical energy) and give off “heat energy” as a by-product etc.

In other words, the energy that “goes out” from the body consists of calories that are expended due to 1) human metabolism (a sum of all of the chemical reactions that take place in the body) and 2) physical activity or human movement.

So think of your fat cells as balloons that inflate and deflate. Inflating when you eat too many calories and then the excess get stored. Deflating when you don’t have enough immediate calories available and the stored energy (in the form of ffas) get released.

*(Super simplified example)

This question came up recently on one of the forums I frequent. I thought it was a good one, so I decided to add my answer here.
