Understanding Net Carbs

What Are Net Carbs?

Net carbs represent the total carbohydrates in a food that your body can digest and convert to glucose. They're calculated by subtracting fiber and sugar alcohols (with some adjustments) from total carbohydrates.

The Formula

Net Carbs = Total Carbs - Fiber - (Sugar Alcohols ÷ 2)

Note: Erythritol is fully subtracted as it has minimal impact on blood sugar.
