I've had bariatric surgery and I've now got several bariatric cookbooks. One of them in particular really stresses that diabetics should have some carbs (+15 grams) with every meal. When this author gives a recipe that includes less than 15 grams of carbs in a serving, she has a special note "If you are diabetic, add some bread, crackers, pasta, or potato to this meal."
My question is, why? Is it because some people still don't dose their insulin based on the carb load of their meal, but take regular doses a couple times a day? Or is there some non-medication-related reason? I've seen this recommendation before that diabetics need to eat carbs, but I've never seen the "why." If you don't eat carbs, what will happen?
I seem to recall that Dr. Bernstein recommends only something like 24 grams of carbs in a whole day, and my understanding is that that's only to allow some variety in the diet. What am I missing?
