You can sometimes, if something is keto then it is most likely low carb. You typically eat 50–150 grams of carbs per day on a low carb diet and less than 20 - 50 grams of carbs on a keto diet. I will often call a recipe keto if it has less than 5g net carbs per serving, otherwise, I will call it low carb. That is just my personal preference.
