Keto Net Carbs Formula:
| From: | To: |
Net carbs represent the carbohydrates that significantly impact blood sugar levels. On a ketogenic diet, tracking net carbs is essential for maintaining ketosis, as they are the carbs your body actually digests and uses for energy.
The calculator uses the standard keto net carbs formula:
Where:
Explanation: Fiber is subtracted completely because it doesn't raise blood sugar. Sugar alcohols are subtracted by half since they have about 50% of the glycemic impact of regular carbs.
Details: Tracking net carbs is crucial for maintaining ketosis on a ketogenic diet. Most people aim for 20-50 grams of net carbs per day to stay in ketosis, where the body burns fat for fuel instead of carbohydrates.
Tips: Enter total carbs, fiber, and sugar alcohols in grams. All values must be non-negative. The calculator will automatically compute your net carbs using the standard keto formula.
Q1: Why subtract fiber from total carbs?
A: Fiber is indigestible and doesn't raise blood sugar levels, so it doesn't count toward your net carb intake.
Q2: Why divide sugar alcohols by 2?
A: Most sugar alcohols have about half the glycemic impact of regular carbohydrates, so we count only half of them toward net carbs.
Q3: What are common sugar alcohols?
A: Erythritol, xylitol, maltitol, sorbitol, and isomalt are common sugar alcohols used in low-carb products.
Q4: How many net carbs should I eat on keto?
A: Most people aim for 20-50 grams of net carbs daily, but individual tolerance varies based on metabolism and activity level.
Q5: Do all countries calculate net carbs the same way?
A: No, in some countries like the UK and Australia, fiber is already subtracted from total carbs on nutrition labels, so you would only subtract sugar alcohols.
