Finding Your Keto Carb Limit This keto carb limit is 35 grams of total carbs and 25 grams of net carbs. (Net carbs are found by subtracting the grams of the fiber from the total grams of carbs.) If net carbs are further limited to less than 20 grams, then most people will get into ketosis even more quickly.
But here's the general consensus: When you're looking at whole foods: net carbs = total carbs - fiber. When you're looking at packaged foods: net carbs = total carbs - fiber and sugar alcohols.
