20's with 10-25 lbs to Lose

Hi. Was just popping in to say hey and share about me. I'm 20 and 6' and 282 lbs hoping to get to 250 by the end of May. I was in the 280s my senior year in high school and when I graduated I just went up from there because I was no longer playing sports or working out. I started trying to lose weight back in the fall of 2011 when I decided I had enough of weighing in the 300s (I was sitting at 310). Through the fall I was able to get down in the 290s but just stayed there and fluctuated from the lower 290s up to 300. In January I got my membership at a local gym that I had worked out at before and I had been hitting it hard and was doing some cardio (mostly walking or walking at an incline) and trying to eat better. As May is getting closer I have started hitting it even harder and doing lots more cardio (running and walking 2+ miles) and have started eating alot better. I have even started a new diet that I have on the challenge page (http://fatsecret.com/challenges/6-week-syntha-6-challenge/Home.aspx) it has helped me lose almost at 10 pounds in a week and a half. I was fluctuating between 289 and 293 and now I am at 282. Hoping to see more results by the end of May.
