You'll find a lot of advice and support here. You'll also find that small changes can be built into long-term healthy habits. And these small changes... they add up.
There are areas based on age, or amount needed to lose (you may want to check out the 100lb Club

), there are a few areas about interests, and there are sections under Diet Central for those looking to connect with people who are working similar plans.
Post wherever you're comfortable.
Best of success!
