This is what we do at my meeting, I think it does vary but it gives you an idea.
The meetings are 2 hours, we arrive and we all sit and chat for 45 mins while everyone gets weighed, this is done in another room, so totally private. While we wait we fill out our pack request for the week and go to the bathroom and pee on a ketostik so the LLC can check you are in ketosis, you can also talk to the LLC in private if you need to. Once a month they also take your bust, hips and waist measurements. In the first week they take your before photos and measurements.
Once everyone has been weighed we watch that weeks DVD (about 15-20 mins) whilst the LLC collects our pack orders.
Then we have about an hour of group counselling and at the end we chat about anything anybody is worried about etc.
My LLC takes debit or credit cards, but you will have to check with yours what payment methods she takes.
It does take a couple of weeks for everyone to settle in and become comfortable with each other. We all get on very well at our group, we are from all different walks of life and ages (16-55) but it makes no difference.
