Is it really possible to lose more fat, just by breathing deeply?  Before I answer that question, it should be obvious that one must eat wisely and exercise to continue losing fat.

 breathing deeply does have its place and the fat burning process.  Molecules of oxygen are necessary for the creation of adenosine triphosphate.  Adenosine triphosphate is a key energy source in the metabolic (calorie burning) process.  Fat burning won’t simply happen by itself unless you get enough oxygen.  Overcoming the typical shallow breathing pattern that most people have will help to feed your metabolic furnace so that it burns red hot.
