Hi! 25-30g carbs sounds really low for South Beach (but by net carbs do you mean that you don't count fiber grams?) I had a Phase 1 day yesterday and the carbs were at 74 g.
is a thread from a while back where we were discussing percentages of carbohydrates (rather than grams), but it might help. When I calculated what the article said should be a typical Phase 1 day, it was 62 g.
It would be almost impossible, I think, to abide by the general guidelines of South Beach and be really low carb, as it includes *4.5 cups* of veggies a day (yesterday, my 1.5 cups of tomatoes alone were 10.5 g) PLUS beans (my veggie chili was 26 g) AND dairy (my Greek yogurt was 9 g). It's not designed to be low-carb, just "good" carb. However, many of us here limit grain servings as we have found out that even whole grains can stall weight loss.
