The South Beach way of life is a very good choice for a diet. It is confusing until you get the hang of it, but the foods are very tasty and overall satisfying. The online services are recommended moreso for this plan than for most others. If you have problems understanding the regular book, try reading the cookbook, which has some clarifications, or see The Good Carb Good Fat book.
