What is Keto Barcode Scanner?

Keto Barcode Scanner is a mobile app that allows you to scan product barcodes and instantly discover if they are compatible with your ketogenic diet. It provides a 1-5 star rating based on net carbs per 100g.

How does the Keto Scan app work?

Simply open the app, scan any product barcode, and the app searches a database of over 2.8 million products to give you the keto rating, nutritional information, and personalized recommendations.

What are net carbs in keto?

Net carbs are calculated as Total Carbohydrates minus Fiber. This is important for keto because fiber doesn't affect ketosis. The Keto Barcode Scanner app automatically calculates this for you.

What are net carbs?

Net carbs are the carbohydrates that your body actually absorbs and affect your blood sugar levels.

Formula:

Net Carbs = Total Carbohydrates - Fiber

Why does fiber matter?

Fiber is a type of carbohydrate that your body cannot digest, so it doesn't affect ketosis.

Example:

Product with 15g carbs and 8g fiber
Net carbs = 15 - 8 = 7g

In the keto diet:

Most people on keto try to consume less than 20-50g of net carbs per day to stay in ketosis.

How is the rating calculated?

The 1-5 star rating is mainly based on net carbohydrates per 100g of the product.

Excellent - Up to 2g net carbs - Ideal for keto

Very good - 2-5g net carbs - Good option

Moderate - 5-10g net carbs - Consume in moderation

Limited - 10-20g net carbs - Use occasionally

Not recommended - >20g net carbs - Avoid

Additional factors:

High sugar (>5g) penalizes rating
High fat and moderate protein are positive

Where does the data come from?

All nutritional information comes from Open Food Facts, a collaborative and free database.

About Open Food Facts:

Open and free database
More than 3 million products
Maintained by volunteers worldwide
Community-verified data

How does it work?

When you scan a product, the app queries the Open Food Facts API and gets:

Product name
Brand
Nutritional information
Product image

If a product is not in the database, you can add it at: world.openfoodfacts.org

Note: Nutritional data may vary by region and product version.

What is the keto diet?

The ketogenic (keto) diet is a low-carb, high-fat eating plan that puts your body into a metabolic state called ketosis.

Typical keto macros:

5-10% carbohydrates

What is ketosis?

It's a metabolic state where your body uses fat as its main fuel instead of carbohydrates.

Keto-friendly foods:

Meats and fish Eggs Cheeses and full-fat dairy Avocados Nuts and seeds Leafy green vegetables Healthy oils

Foods to avoid:

Sugars and sweets Grains and cereals High-sugar fruits Legumes Tubers
