Is avocado really keto? What about a banana, or plain peanut butter? Each answer breaks down total carbs versus fiber and tells you exactly what to check on the label — backed by the Foodsage ingredient checker.
Avocado is one of the lowest-carb fruits available and is mostly monounsaturated fat, which is why it is a staple on almost every keto food list.
A medium banana carries roughly 24 grams of net carbs, which is enough on its own to use up most of a strict keto day's carb allowance.
Plain natural peanut butter is low enough in net carbs to fit a keto diet in moderation, but added-sugar brands and low-fat versions change the math.
Plain full-fat Greek yogurt is low enough in net carbs for keto in normal servings. Flavored and low-fat cups usually add enough sugar to push them out.
Quinoa is often marketed as a health food, but a single cooked cup carries around 34 grams of net carbs — well above most keto meal budgets.
