I belong to DONE BEING THE FAT GIRL Team, and to the BECK Team, (we have read Dr. Beck's book, as she's been slim for over 20 yrs.) and I make new friends all the time.
You are right that many people don't check in and MOST people give up and quit. I've been here nearly six years and few people are still here from when I joined. It is like getting older doesn't matter and that they had the idea six years ago to join Sparks and they QUIT. I didn't get to my goal yet, but I've never been back up to that 214# I was when I joined, so I feel that that is a success.
