New to this site

I am DebBostons. My husband and I are retired and love our 2 boston terrier dogs. I started this last week and only kept track of my food 2 days and gained weight. So I started again Monday and have done it for today. I think it's a wonderful site. I have been a member of T.O.P.S. for many many years and the last couple I have just yo-yoed. I want to get serious. I have a problem with any exercising because of arthritis. I had a series of 3 shots in my knees and I only have a few more weeks to see if they will get better. Next week I am getting injection in my spine.
