You'll find fabulous advice and support here. Check out the various forums for something similar to your approach to food and exercise. For example, there are forums or sub-forums for South Beach, calorie-counting, Intuitive Eating, wholefoods, vegetarian, and so on.
Lots of people also get daily support on threads based on age (for example, 20-somethings, etc) or location in the world, 100#s to lose, or even motorcycles. Explore, and even start your own.
