Why have I only lost 10 pounds?!?

I am 5'7 and 155 pounds now. I have a torso that is my main problem. My legs are great but once you hit the torso it is like FAT. So I have cut a ton of calories out and eating super healthy and I started exercising like crazy as well. I do Insanity. I don't know if you know what that is, but its like really intense cardio for 45 minutes. On top of that I run as well. I have been doing this for 2 or 3 months now and I thought I'd lose weight a lot faster. What's going on?!
