Keto barcode & food lookup

How it works

Barcode or name. Use the Barcode tab for digits, or Food to type a brand or product.
Instant analysis. We look up nutrition and ingredient facts from our database.
Get your verdict. Receive a clear keto verdict, net carb count, and alerts for hidden sugars when data allows.

Can't scan? No problem.

Desktop ready: Perfect for when you're browsing on your computer without a webcam.
Low-light reliability: Manually enter codes in dim grocery aisles where cameras struggle.
Shop online smarter: Easily copy and paste UPCs from online grocery listings or screenshots.
Total accessibility: A reliable backup for when camera hardware or blurry labels won't cooperate.

What's inside every search?

1–100 Keto rating: An instant "grade" based on macros and ingredient quality.
Precision macros: Net carb calculations (whenever data allows) to keep you in ketosis.
The 5-point verdict: Five clear categories: Excellent, Good, Caution, Avoid, or Unknown.
Hidden ingredient flags: Instant alerts for added sugars or fillers that spike insulin.
Expert transparency: Clear notes when data is limited, ensuring you always have the full story.

Supported barcode formats

North American standards (UPC-A): Full support for the standard 12-digit codes found on most US and Canadian products.
International products (EAN-13): Complete compatibility with the 13-digit codes used across Europe and the rest of the world.
Compact packaging (EAN-8): We offer "best-effort" support for 8-digit codes found on small items. If the digits validate, we'll find the data.

Can't find your product?

New to the shelf: Freshly released snacks or seasonal items can take a few weeks to hit our global database.
Exclusive brands: Some "private label" or store-specific brands (like some Aldi or Trader Joe's items) don't always share their UPC data publicly.
Niche & local: Small-batch makers or local artisans may not have public digital listings yet.
Typos & snippets: Double-check that you've entered all digits, including the smaller numbers on the far ends of the barcode.

FAQ

How do I use a UPC for a keto lookup?: Enter the 12 or 13-digit UPC/EAN code into our search bar. This allows our keto scanner to pull the specific macro profile for that product.
What types of food can I check for keto-friendliness?: You can check any packaged grocery item. Our database cross-references nutrition facts to provide a keto verdict and net carb count.
Why is there no keto score for my barcode?: This usually happens if the barcode is incomplete or if the product's nutrition data is missing "Net Carb" essentials like fiber or sugar alcohol counts.
Is this a global keto barcode scanner?: Yes. By supporting EAN-13 and UPC-A formats, we provide keto data for products in the US, Europe, and beyond.
Is manual barcode entry reliable?: Yes. Manual entry is a 100% accurate way to access our food database when you don't have a camera handy or are browsing on a desktop.
