Yes, I have, but it wasn’t all that successful, although we may have given up too soon. We started it because many people in our 10 week program expressed interest in ongoing support. It was free (I work in Public Health) but we still only consistently had 3-6 people (out of over 100 people) show up each monthly session (and I always sent email reminders beforehand) so after 6 mos we discontinued it, at least for now. The most “popular” one that we had was when we combined it with a guest speaker and had a little interactive chair exercises during. We sat in a circle instead of “class/row style” with everyone looking at the speaker. The circle felt more intimate.  Our Diabetes Support group also has monthly guest speakers for their format too and it is pretty well attended.

Having an educational session or topic to discuss first or at least get things going seemed to break the ice bit to help get people to talk about how their doing.

Another national weight management support group that I’ve looked into a bit and my mom attended for awhile (membership is cheap, like $30/year) called TOPS (Taking off Pounds Sensibly)  http://www.tops.org/desktops.asp

Hope that helps.
