      Ok so I had to have a think and research a bit before I answered this. So the nervous system does not store fat but interesting the central nervous system does control how much we eat and when we are hungry. Also your stored fat releases factors that send signals to your brain as well. Factors secreted from fat are called adipokines and act in a similar way to hormones. One such adipokine is leptin and some people are born without the gene for leptin and become very fat as children becuase there is no signal to the brain to say that they are full. They remain hungry all the time. If you give them leptin as a medicine they are able to lose weight. This is a great example of how science can identify the cause and find a treatment for a disease. Pretty cool
