How is excess fat eliminated from your body?

Question

What I am trying to get at is, when you are dieting and excersizing, how is the stored body fat expelled from your body? Is it used by your system? Is it expelled in your "morning ritual"? Just curious.

Answer 1

You body uses it and your body sends signals that in coming food should be turned to sugar for use rather than fat for storage, as you are going to use it up pretty quickly. When you don't exercises or eat too much fat, your body can't possibly use it all so it turns it to fat to use later. Think of it like this if you were only given 20$ a week to live on you would spend it. If you were given 200000$ a week you would put some in the bank for later. The money in the bank would keep growing weekly, fat works the same.

When you are in the fat burning cardio zone your body is turning your fat supplies back into glucose to be used.

Answer 2

Fat molecules consist of three fatty acid chains connected by a glycerol backbone. Fatty acids are basically long chains of carbon and hydrogen and are the major source of energy during normal activities.

Fatty acids are broken down by progressively cleaving two carbon bits and converting these to acetyl coenzyme A. The acetyl CoA is the oxidized by the same citric acid cycle involved in the metabolism of glucose. For every two carbons in a fatty acid, oxidation yields 5 ATPs generating the acetyl CoA and 12 more ATPs oxidizing the coenzyme. This makes fat a terrific molecule in which to store energy, as the body well knows (much to our dismay). The only biological drawback to this, and other, forms of oxidative metabolism is its dependence on oxygen. Thus, if energy is required more rapidly than oxygen can be delivered, muscles switch to the less efficient anaerobic pathways. Interestingly, this implies that an anaerobic workout will not "burn" any fat, but will preferentially deplete the body of glucose. Of course, your body can't survive very long on just anaerobic metabolism...it just can't generate enough energy

Answer 3

You get rid of it by doing anything. It's energy. You can sit, and type and get rid of weight that way. It's just gets burned off.
