Weight loss

I'm going to be perfectly honest. I've gained 20 lbs since moving here in the US 2 1/2 years ago. It's probably mostly my fault because I've let myself be complacent and I quit exercising. I've also indulged in the fastfood craze that best defines America. And though I still don't look obese, I'm not too comfortable anymore. I get frustrated when my clothes don't fit right, and yet I refuse to buy new clothes one size bigger. I'm determined to go back to my old size. It's harder for me to lose weight now that I'm older. I think I will have to learn how to build muscles to burn more fat. It can be done. I just need to FOCUS.
