How we calculate the Net Atkins Count™

In the Atkins Nutritional Approach, the Net Atkins Count™ is calculated by subtracting the number of grams of fiber from the total grams of carbohydrates in whole foods. This reflects the fact that fiber doesn't impact blood sugar levels. Moreover, in the case of products that contain glycerin and other sugar alcohols (also known as polyols), which also have a negligible impact on blood sugar, they too are subtracted from the total carbohydrates to yield the Net Atkins Count™.

The glycemic (blood sugar) impact of Atkins bars and ready-to-drink shakes has been tested on volunteers, meaning that you can rely on the accuracy of the stated Net Atkins Count™.
