I have Type 2 diabetes and started out on Schwarzbein after deciding to go low carb. Her recommendations for diabetics is 15 g per meal of "real carbs" (beyond non starchy veggies). Using my glucose meter, I found that carbs such as grains, potatoes, & high sugar fruits raised my blood sugar. I later found that if I cut out starches all together, my blood sugar is even better. Now I pretty much get my carbs from non-starchy vegetables, nuts & seeds, and a few low sugar fruits.

Bottom line, the idea of protein, fat, & non-starchy vegetables, with some nuts, seeds, and low sugar fruit, works for me, but most other carbs are pretty much off limits or eaten only occasionally. I'm doing better on a lower level of carbs than Dr. S recommends.
