I'm a thin guy, weigh around 58kg and 5.6' hight. My problem is I don't have fat anywhere else but on belly. I don't know what is the reason. I'm skinny as hell and have been trying to reduce my belly fat by reducing food intake. However, it doesn't seem to work at all.

Any suggestions what could be the reason and how to overcome this issue?

One more question. If try to gain weight, how will it effect my problem?
