However, replacing high carb flours like all-purpose flour, wheat flour, corn flour, and rice flour with low-carb flour is not as simple as just using one for the other. Due to the difference in composition between high-carb and low-carb flours, you will need to use different amounts of low-carb flour together with other essential ingredients that you don’t typically find in traditional baking recipes like psyllium husk, xanthan gum, and protein powder.
Almond Meal is made slightly different than almond flour. Instead of blanching the almonds to remove the skins, the skins on the almonds are kept on. It’s a little bit coarser than almond flour and still bakes the same. For baked goods, I like to use a super fine ground almond flour but I will equally use almond meal as it seems to perform just as well in most recipes, at a reduced cost.
Most low-carb diet authors don't recommend bothering with it. Even many of those who think a ketogenic diet is a good thing just assume that a very-low-carbohydrate diet (under about 50 net grams of carbohydrate) is ketogenic.
