So for the past couple years, without really doing any exercise, I have noticed my stomach looking strange. I have large sections around my belly button that there is pretty much no fat, but all around it there is. What would cause the fat in just those areas to "disappear" without exercise? I don't want to complain about a lack of fat of course but just want to know what is causing it. My doctor said is is strange but wasn't concerned. I have tried searching for pictures of people with a similar issue but have found nothing.
