"South Beach Diet Official Updates



December 2003 update: The SBD companion book, Good Fats Good Carbs Guide, was released this month. Low fat and fat-free milk and yogurt are now listed in the Phase 1 Foods to Enjoy list. I have some recipes here in the Phase 2 categories because they contain low fat/nonfat milk or yogurt. I'll move these to Phase 1 as I have the time. In the meantime, if you see something in Phase 2 because of these dairy products, know that it's now okay to use them in Phase 1 also.



January 20, 2004: Updates from the South Beach Diet Online's The Daily Dish.
The South Beach Diet (SBD) continues to evolve as new nutritional studies and information come out. Recently, the results of new studies have shown that some of the "foods to avoid" may not be as bad for us as the original studies on glycemic index demonstrated. There are also some new, exciting studies about the role calcium plays in weight loss. The end result is that you can continue to enjoy all of the foods recommended for the SBD—as well as adding back in a few of your favorites! Here are the major changes:



Milk


Old Version:

Avoid all dairy in Phase 1, except for less than 2 tablespoons fat-free half & half, nonfat milk, 1 percent milk, or soy milk allowed with coffee.



New Version:
Phase 1: Now includes low-fat milk (fat-free and 1 percent), soy milk, and yogurt (low-fat or fat-free plain or vanilla light/lite only) on the Phase 1 "foods to enjoy" list.

Phase 2: May add light/lite fruited yogurt as a "food to enjoy" in Phase 2. Note: Since the SBD is still low in saturated fat, high-fat whole milk products will remain on the "foods to avoid" lists for all Phases.



Tomatoes



Old Version: Limited to one whole tomato or 10 cherry tomatoes per meal in all Phases.

New Version: Not limited in any Phase.



Onions



Old Version: Limited to ½ per day in all Phases.

New Version: Not limited in any Phase.
Carrots



Old Version:
Avoid carrots in Phase 1 and 2; allowed in moderation in Phase 3.

New Version:
Allowed, starting in Phase 2."
