I am doing pretty much the same, started last October and lost 10+kg since. Just feels waaay better. Key for me is to stay away from pasta, pizza, the too regular bottles of wine, too much bread and the cookies. And go to the gym regularly. It's just so easy to get out of shape (hahaha at "but round is a shape"), and it's so difficult to get back.

Good luck & keep going, it's definitely worth the effort.
