This part of the forum is called Support, and the threads here are generally when someone is needing support-they are having a bad day, they are having trouble staying on track and need a kick in the keister-just general support.
As far as diet issues, there are different sections of the forum that deal with certain plans if you will-such as Weight Watchers, low card, Beach, and others. If you don't see the plan that you are on-check under General Diet Plans-there are lots of plans there listed as well such as calorie counting, Jorge Cruise, and others.
There is a great exercise section of the forum-that is broken up into Ladies Who Lift (strength training), general exercise, and exercise videos.
There are some great nooks and crannies here in this forum-everything from general chatter (non diet related) to recipes suitable for different plans. Welcome!
