As with many people, I am always trying to lose weight. Recently I found this site for weight loss called SparkPeople. It is a big community and there are recipes too. I joined (for free) and setup my goals and started tracking my food and exercise. Looks like they have some good recipes I will have to try.
I am sure there are lots of features that I haven't found yet, but they do have an iPhone/iTouch App for it. Check it out.
