Blueberry muffins are a sweet baked good made with flour, sugar, and blueberries. While blueberries themselves can be relatively low carb in small portions, muffins concentrate both refined flour and sugar, making the finished product high carb and not compatible with low-carb, keto, or diabetic-friendly eating.
