Classic donuts made with wheat flour and cane sugar, like the ones you get at Dunkin Donuts, are not approved for a low carb diet. They are incredibly high in carbs and sugar and will raise your blood sugar, kicking you out of ketosis. Fortunately, you can make delicious keto donuts using almond flour and a natural sweetener, including an optional glaze to really satisfy your craving. They'll remind you of Krispy Kreme donuts, but they're approved for a low-carb diet.
