I'm Trying to Lose Weight!

Good god I don't know what else to do. I am trying and trying to lose weight, and it ISN'T GOING ANYWHERE! It is really true that the older you get the harder it is to lose weight. I'm eating veggies, grilled meat, fruit, and I lost like 2 pounds. What the heck! I guess I will have to find a good diet pill I just am not sure what else to try! I also worry about once I get it off how to keep it off. If anyone has any suggestions I'm all ears.
