Keto Certification Standards
The Keto Project™ Standards for verified foods, beverages, and supplements.

NET CARB LIMITS
| Product type | Standard limit | Qualifying formulation |
|---|---|---|
| Meals | 10 g | 12 g |
| Snacks | 6 g | 9 g |
| Condiments | 3 g | 4 g |
Products must be at or below the applicable limit.
Higher limits apply to formulations containing minimally processed whole-food ingredients or ingredients with reduced digestibility. The Keto Project determines eligibility for these limits during its review.
We use the serving size printed on the product label and validate it against applicable U.S. FDA serving-size requirements.
Other products are reviewed individually.
Standards updated October 25, 2026.
NET CARB CALCULATOR
This is how you calculate net carbs from a nutrition facts panel.
Use the nutrition label to enter total carbohydrate, sugar alcohols, dietary fiber and allulose per serving, not per 100 g. Enter allulose only in the Allulose field. Net carbs = total carbohydrate - dietary fiber - sugar alcohols - allulose. The Keto Project deducts 100% of dietary fiber, all sugar alcohols and allulose included in total carbohydrate. Use amounts per labeled serving and deduct each amount only once. We follow applicable FDA rules for serving sizes and all rounding.
Knowing the net carbs in your food items can reduce the amount of glucose production and ensure your foods and serving size fits within a ketogenic diet. If you would like to embed this calculator on your website, you copy the code for free here: ketoverified.org/calculator
A 9 g snack under these standards
A snack with 20 g total carbohydrate, 5 g dietary fiber, 4 g sugar alcohols and 2 g allulose per labeled serving has 9 g net carbs under The Keto Project formula. These illustrative deductions are included in total carbohydrate.
20 − 5 − 4 − 2 = 9 g
Try the net carb calculator| Snack limit | Net carbs per serving |
|---|---|
| Standard | At or below 6 g |
| Qualifying formulation | At or below 9 g |
This example exceeds the standard snack limit. The 9 g allowance applies only to formulations containing minimally processed whole-food ingredients or ingredients with reduced digestibility, as determined by The Keto Project during review. Meeting a carbohydrate limit alone does not establish certification eligibility.
