As my title says, I'm a serial rejoiner
I lost quite a bit of weight on WW in the past (on the wonderful old exchange plan), kept it off for five years, then ballooned to my start weight. I really don't remember what I weighed when I first joined 3FC. I know I've gained since I first came (not 3FC's fault, of course!). I gained by putting on 5 to 6 pounds a year and not taking it off -- stupid, no? I've lost 39 pounds since 2005, which is ridiculously slow, but better than gaining another 30-35 pounds during that time.
I've done this mostly through WW, with several switches to one low carb plan or the other. I lose like magic on low carb, but can't sustain it. I go back to WW and start eating too many carbs. This time, I hope I will find the balance. I'm doing WW online. I went back to my old meeting, but this group talks about food constantly, and how to substitute a low fat chocolate concoction for a beloved high fat one, and this isn't helpful for me. It's the only meeting I can count on being able to attend regularly, so I'll go it alone. I'm very self-motivated, and I've always been successful on WW when I've focused on it, so I'm counting on that this time.
