Interestingly enough, you are never going to decrease your fat cells. You keep the number of fat cells your whole life, what changes is if they increase or decrease in size.
As far as losing fat, the cells in your body break it down into its subunits when they are in need of energy, such as when you are on a calorie deficit. Energy is released when the fat is broken down and utilized by the cells. (bonds breaking = energy released). Also, those subunits of the fat I had mentioned, the cell may utilize them to build new, but different fats - such as being incorporated into the cell's membrane.
Fat cell -- broken down -- energy used in cellular reactions, subunits used in non-fat cells.
