Hi Karen~
If you go to the main page of this message board, with all the different forums listed, you go down to the 4th one. The first is "announcements", 2nd is "success stories", 3rd is "support forums" and the one you're looking for is the 4th, "diet central". And that section includes every kind of diet you can think of.
If you're not sure which one you'd like to try, just go to that area, pick a few that sound interesting, and read some of the posts and threads in that section.
I did Atkins....so I was in the low-carb category (of which there are several different plans).....and then went to the Atkins sub-category.
And when you choose one.....join in on that particular forum and you will begin to get all sorts of friends, advice, information and support there from others who are doing the same plan you are.
It can be over-whelming and even confusing when you first get here...mainly because there are SO many different sections and forums here.
