Lipolysis is the process by which fat cells (adipose tissue) reduce in size or get eliminated to free up the energy stored in them. The energy is stored as triglycerides which then get converted to fatty acids and glycerol that your body can use directly for muscles and other organs.
It's important to note that normal weight loss does not get rid of fat cells but only shrinks their size. Fat cells will naturally be removed during their lifecycle (cell turnover) at a rate of 10% per year.[1]
Weight loss will also eliminate fat from all areas of the body at once, although hormonal factors will influence how much is maintained in a gynoid or android fat pattern. This means you can not remove fat in a specific area using exercise which makes it harder to shape your body.
The only way to remove fat in a specific area is with special medical procedures developed to target fat.
