How it works
Net carbs equals total carbohydrate minus fiber, using the two figures on a nutrition label, both in the same unit. If the fiber is larger than the total, the result is shown as zero.
Counting methods differ from person to person, so check the label yourself before you rely on the figure.
Worked example
A food with 0.7 oz of carbohydrate and 0.2 oz of fiber has 0.5 oz of net carbs.
Questions
Is fiber always subtracted?
That is a choice some people make. Counting methods differ, so the label is the place to check the figures.
Where do I find the numbers?
Look for the total carbohydrate and dietary fiber lines on a nutrition label. Enter both in the same unit.
Does this say whether a food is right for me?
No. It only does the arithmetic. Food choices are best discussed with your doctor or a dietitian.
