Hi Devon &
You may want to check out the 20-somethings, and Diet Central to start. They'll help connect you to chicks your age, and maybe point you to a few plans that others on the site are using.
Basically, we're just a bunch of people trying to live a healthier lifestyle. Giving & getting support. Learning new things about how to eat, how to stay on plan, how to exercise more.
Look around. Post wherever you're comfortable!
