What are Net Carbs?
Net Carbs are the carbohydrates that your body actually digests and converts into glucose (blood sugar). Understanding this distinction is crucial for diets like Keto, Atkins, and for managing Diabetes.
The Simple Formula
Fiber functions as a filler and passes through the body undigested. Sugar alcohols (like erythritol) are sweet but have a different molecular structure that makes them indigestible to varying degrees.
Frequently Asked Questions
Why do we subtract Fiber?
Dietary fiber is a type of carbohydrate that the body cannot digest. Since it doesn't raise blood sugar or trigger an insulin response, it is subtracted from the total carb count.
What about Sugar Alcohols?
Sugar alcohols (like Erythritol, Xylitol) are sweeteners that are incompletely absorbed. Most people on Keto subtract them from the total count, though some (like Maltitol) can have a small glycemic impact.
Should I count total or net carbs?
Counting Net Carbs allows for more vegetable and fiber intake, which is generally healthier. Counting Total Carbs is stricter and may be necessary for those who are very insulin resistant.
