Congrats! It's a huge sense of accomplishment, no? I did a similar thing around the same time ago -- started eating better (out with the Frosted Mini Wheats for breakfast, in with the Greek Yogurt), started running, and lost 30 lbs in about 6 months. No supplements either. Best life improvement I've ever made.
Thanks and congrats to you too. I have found a lot of people that are into fitness on hn. Taken a few tips here and there. The no supplements thing was something I was just determined to do. In my mind, I ate to get fat, and now I needed to eat to get fit. That perspective helped me out a lot. I wanted to mention that I achieved my results so far without a gym membership. I did put together a small @ home gym, but its not the same as a gym. Just been able to really stay motivated.
