Hi, Angfea!
Make sure you are getting a lot of protein, but Barb is right...your loss is normal. You might want to PM Mauvaisroux...she is moderator of the Alternachicks forum and handles their Vegetarian recipe boards. She does a WW/SBD combo and might have some tips. Also, post in the main forum (Fat Chicks on the Beach) for help with SBD and being Vegetarian...there are a couple there that can help you.
So glad to see you here and hope to hear more from you! Congratulations on your loss!
