http://www.sparkpeople.com. There are some really great tools over there that can help you reach the healthy lifestyle that you are looking for. The community is great and very supportive. I lost 40 lbs with the help and support of their 4 step plan. It is not an intensive crash diet, but a lot of small steps to reach your big goal. You didn't get where you are overnight. It is going to require a lot of patience. If you start the plan don't look back until about 6 months in and I think you may be pleasantly surprised. Then quickly turn around and head forward again.
