About Us

The Keto Scan was built to make keto eating simpler and smarter. We know how frustrating it is to flip a product over, squint at the nutrition label, and try to calculate net carbs while standing in the grocery aisle.

Our mission is to give you an instant, honest answer about whether a product fits your keto lifestyle — no guesswork, no marketing spin, just the numbers that matter: net carbs, per serving, right now.

How it works

Scan or enter a product barcode and we look it up across three databases — Edamam, USDA FoodData Central, and Open Food Facts — to find the most complete and accurate nutrition data available. We then calculate net carbs (total carbs minus fiber and sugar alcohols) and give every product a Keto Score from 0 to 100.

Our scoring system

🟢 Very Keto-Friendly — 0–3g net carbs per serving (score 85–100)

🟢 Keto-Friendly — 4–6g net carbs per serving (score 70–84)

🟡 Moderate — Portion Matters — 7–10g net carbs per serving (score 50–69)

🟠 High for Keto — 11–15g net carbs per serving (score 25–49)

🔴 Usually Not Keto-Friendly — above 15g net carbs per serving (score 0–24)

These ratings are per serving of the product, not your total daily carb budget. Always factor in everything else you eat during the day.

A note on accuracy

Product databases are crowd-sourced and maintained by volunteers and manufacturers. Occasionally a serving size or nutrient value may be incorrect. We always show you a "Label doesn't match?" option so you can correct anything that looks off. When in doubt, read the label.

Not medical advice. Consult a healthcare professional before making significant dietary changes.

How we create our educational content

Our educational articles (like our guides on what keto is and how to calculate net carbs) are written and maintained by The Keto Scan Editorial Team. Here's how we approach that content:

We draw on authoritative government, institutional, and peer-reviewed sources — such as the U.S. Food and Drug Administration, the USDA, and the National Institutes of Health — and check that each source we cite actually supports the specific claim next to it, rather than citing a source that only loosely relates to the topic.

We keep general nutrition education clearly separate from personal medical advice. Nothing on this site is a diagnosis, treatment plan, or individualized recommendation — for that, please talk to a qualified healthcare professional, as outlined in our full Disclaimer.

We review and update articles when the underlying information changes, when we find a claim that needs better support, or when our own scoring methodology changes. Each article shows a "Last updated" date reflecting the most recent review.

We do not claim that our content has been "medically reviewed" unless a named, qualified reviewer has actually reviewed it and their identity and credentials are disclosed on the article. At this time, our articles are written and reviewed by our editorial team, not by a medical advisory board or clinical reviewer.

If you spot something that looks outdated, unsupported, or incorrect, we want to know — please reach out through our Contact page and we'll review it.
