Sure Keto is a system that can calculate the keto rating of foods based on their ingredients, net carbs, and fat content.

We also provide rankings for different food categories so you can easily choose the best keto-friendly options.

We currently have over 60,000 food products in our database, and we are still adding more every day.

Keto Ratings

We have 6 rating groups to guide you in your keto food choices. From best to worst:

Sure Keto!


  • Low in net carbs
  • High in healthy fats
  • No unhealthy ingredients
  • Whole food, organic, grass-fed, or pasture-raised


  • Avocado
  • Flaxseed
  • Olive Oil
  • Grass-Fed Butter / Beef
  • Salmon


The majority of your food choices should come from the SURE KETO group because they are low in carbs, high in fats, and made with healthy ingredients.



  • Low in net carbs
  • No unhealthy ingredients


  • Broccoli
  • Asparagus
  • Cauliflower
  • Pecans
  • Sardines


Foods rated as KETO-FRIENDLY are generally low in net carbs but are not necessarily high in fats. You may eat these foods as supplementary to SURE KETO foods.

Keto in Moderation


  • Moderate net carbs
  • No unhealthy ingredients
  • Also includes low-carb alcoholic beverages


  • Almonds
  • Strawberry
  • Brussels Sprout
  • Scallops
  • Vodka / Rum / Gin


Foods rated as KETO IN MODERATION have a moderate amount of net carbs so you need to be mindful of their serving size.

Low-carb alcoholic beverages also fall under this category since alcohol consumption should always be limited even if they are low in carbs.

Dirty Keto


  • Low in net carbs
  • Contains unhealthy ingredient/s


  • Diet Soda sweetened with aspartame
  • Bacon with sodium nitrate as a preservative
  • Margarine made with vegetable oils
  • Pork rinds fried with vegetable oils
  • Coconut cream with carrageenan as a thickening agent


Foods rated as DIRTY KETO are low-carb foods with unhealthy ingredients. You may still lose weight eating DIRTY KETO, but it may also lead to health problems in the long run.

We recommend avoiding foods from this group. You should instead choose low-carb, whole foods to achieve a healthy weight loss on keto.

Avoid or Minimize


  • High in net carbs
  • May or may not contain unhealthy ingredients


  • Watermelon
  • Peanuts
  • Beets


We recommend avoiding foods from the AVOID OR MINIMIZE group whenever possible. You may still eat some occasionally, but it should be in a small serving size.

Not Keto!


  • Very high in net carbs
  • May or may not contain unhealthy ingredients


  • Potatoes / Sweet Potato / Yam
  • Black Beans / Pinto Beans / Mung Bean
  • Apples / Banana / Mango
  • Bread / Ice Cream / Candies


Foods under the NOT KETO group should not be consumed while on keto because they are very high in net carbs.

These foods may prevent you from reaching or maintaining ketosis even with small serving size.

Rating Factors

We use the following factors in our keto rating system:

1. Ingredients

Products made with grass-fed, pasture-raised, or organic ingredients will have a higher rating. Unprocessed whole foods will also have a higher rating.

On the other hand, products that contain artificial sweeteners, high-glycemic sweeteners, highly refined oils, or controversial food additives will have a lower rating.

Here is the list of ingredients that we check: sweeteners, oils, and food additives.

2. Net Carb Density

We adjust the macros to 100g serving size (or 240ml for liquids), so we can rate foods based on the same serving size.

We then get the net carb density by subtracting fiber and sugar alcohols from total carbohydrates.

Net Carb Density = (Carbs - Fiber - Sugar Alcohols) per 100g serving size

Net Carb Density is a more accurate way of comparing net carbs since serving sizes differ for each brand and food type.

3. Healthy Fat Content

Foods that are high in fats will get a bonus score only if they don't contain unhealthy ingredients.

For instance, margarine is high in fats but will not receive the bonus since it is made with highly-refined oils.
