, TrampledUnderfoot! This way of eating is very doable for your entire family to follow, and will set good guidelines for your children for the rest of their lives. You can cook regular meals, just substitute whole wheat pasta and breads, rather than white, brown rice instead of white, and serve sweet potatoes rather than white potatoes. Of course, you won't be able to have grains or potatoes on Phase 1, but you can enjoy the meat and vegetables. When you buy cheese, always select the lowfat varieties, and use the leanest cuts of meat.
As far as which book you should get, the newest book, SouthBeach Super-charged, has the most up-to-date food lists for each Phase, and includes some exercise ideas. But the older version of the SouthBeach Diet Book will work, just as well. We do keep our food lists in our FAQs up to date with the lastest changes, but it's essential to read the book, too.
There are many South Beach recipe books on the market, and all of them are pretty good, so it's a matter of preference. We also have some wonderful tried and true recipes in our recipes section of this forum.
Good luck to you, and we hope to see you around here often!
