Frequently Asked Questions
How do I know if a food is keto friendly?
Scan the barcode with The Keto Scan. Products with 0–3g net carbs per serving are Very Keto-Friendly, 4–6g are Keto-Friendly, 7–10g are Moderate, 11–15g are High for Keto, and above 15g are Usually Not Keto-Friendly. Net carbs are calculated as total carbs minus fiber minus sugar alcohols.
What are net carbs?
Net carbs are the carbohydrates your body actually absorbs. The formula is: Net Carbs = Total Carbohydrates minus Dietary Fiber minus Sugar Alcohols.
How many net carbs can I have on keto?
Most people on keto aim for 20 to 50g of net carbs per day. The Keto Scan scores individual products per serving, not your daily total.

Yes. The Keto Scan is completely free to use. Scan any barcode and get an instant keto verdict at no cost.
