SouthBeachDiet.com is a great resource for losing weight. As you can probably guess, it is the companion site of the South Beach Diet book. I found it to be very helpful because of all the tools it has... a meal planner, shopping list generator, and so on. It's like having a nutritionist right beside you in your journey to weight loss! The only issue I had was that before I could use any tools on the site, I had to answer question after question after question about my health and weight loss goals. However, I did feel somewhat lost, as I haven't read the actual book.
