Just starting up again

Options
Well, I'm about to be 21. I figured now's a good time as any to start learning to eat right for once. If anyone has any tips on bargain healthy eating, let me know. I could use some support. I'm starting out here at 251 pounds. I have an elliptical, so I plan to get on it and start doing more walking. So, if anyone wants to be friends, let me know! I'll be as supportive back as well!
