Yes, apparently the body has an "order" for fat loss.
This means that you will likely lose fat in the extremities before you will lose it in the abdominal area. Women often lose it from the upper hips and thighs last.
It supposedly has to do with the number of receptors in that area... either the "let go of it" receptors are lower in number or the "collect it" receptors are higher, or both.
There was an article on here talking about it. Rest assured, if you keep on losing, then eventually the gut will have to go, but it may take a while to get there... just keep working at it.
