I used to go to a group but now I'm doing it by myself (and with minimins!!) If you never done it before I would say it's worth doing it online if you can't get to a group, at least until you get the hang of the plan (which won't take long). Also make use of everyone on here because minimins is a brilliant support network.
I do green days which lets me eat lots of pasta, rice etc, I'm not a big meat eater, but you could do red days if you're more a meat person are Extra Easy which is the current plan and gives you the best of both worlds.
Hope this helps, any questions just ask I'll try to answer them.
