I do not eat grains often. Not because of gluten but because there are far better sources of carbs,
Lunch for me is 6-8 oz of grilled chicken, sometimes grilled or sautéed veggies and normally blueberries. This is only during the week. On the weekends I eat whatever. Berries are low GI so my blood sugar levels never get above 125 mg/dl even when I do have more refined carbs. Fasting I am in the high 70s.
