Peanut butter is one of the tastiest, most popular spreads in America. 

Whether you take a spoonful straight out of the jar as a midnight snack or mix it in with your protein shake, peanut butter is good with pretty much everything.

And with keto now established as a staple diet, people worldwide are looking for low-carb snacks to complement their lifestyle and stay under their daily carb limit.

In their search, many people wonder, “is peanut butter keto?” Does it have a place in your ketogenic diet plan?

Generally, yes. Low-carb peanut butter is a high-fat and moderate-protein food. But, as you're about to find out, not all brands of peanut butter are equal — some commercial brands contain unhealthy ingredients and added sugars, which can spike the net carb amount.

        What is peanut butter?

        Peanut butter, scientifically known as Arachis Hypogaea, is a bedrock spread in American culture. Unlike other snacks, peanut butter is considered an unprocessed food, made by simply grinding up roasted peanuts until they turn into a paste.

        First popularized by prolific agricultural scientist George Washington Carver, peanut butter rose in prominence during Carver's numerous campaigns to encourage peanut consumption in order to offset the nutrient depletions brought on by excessive cotton farming.

        During these campaigns, there was probably little concern about the amount of carbs in peanut butter. But today’s health-conscious society is often keen to know its nutritional content.

        Peanuts are actually considered a legume rather than a tree nut, placing them in the same family as soybeans, lentils, and peas. But, since peanuts have a practically identical nutrient breakdown as tree nuts, most people consider it a nut. 

        This often leads people to wonder, “are peanuts keto?” And for anyone a strict diet, looking for low-carb peanut butter becomes crucial. 

        Is peanut butter keto?

        Yes. If you eat it in moderation, peanut butter is a keto-friendly and healthy snack to add to your keto diet.

        The standard ketogenic diet requires you to keep net carb consumption under 50 grams per day. At just 4 grams of net carbs per serving, you can safely consume peanut butter as long as you stick to a low carb peanut butter and stay under your total daily carb intake. This means you’ll have to be conscious of the carbs in peanut butter to ensure you stay on track with your ketogenic diet.

        The allure of peanut butter on keto also comes from its perfect macronutrient ratio. When looking into how many carbs are in peanut butter, let’s look at two tablespoons of all-natural peanut butter:

        • Calories: 188
        • Total Fat: 16g
        • Total Carbohydrate: 6g
        • Dietary Fiber: 1.9g
        • Net Carbs: 4.1 g
        • Protein: 8g

        Peanut butter is also great:

        • As a pre-workout snack to help fuel your exercises when carbohydrates are restricted.
        • To satisfy sugar cravings that may arise in the initial stages of keto.
        • When you want to stay in ketosis while traveling and have limited food options.

        But remember — everything in moderation!

        If you are incorporating peanut butter into your keto diet plan, it's crucial that you track the exact amount you are consuming because it's extremely easy to overeat. Peanut butter is delicious, and while a spoonful here or there can feel safe, if you snack too much in a single day you'll definitely blow past your limit.

        The best way to prevent this is to measure out your snacking in tablespoons and to always check the nutrition label to make sure you choose peanut butter brands that skip any unhealthy ingredients like added sugars, vegetable oils, or trans fats.

        Benefits of eating low carb peanut butter

        Peanut butter is packed with nutrients and dietary fats, making it a great snack for people who are frequently out and about while on the ketogenic diet.

        Here are a few benefits of peanut butter consumption:

        • Nutrient-dense. All-natural peanut butter contains ample amounts of healthy micronutrients including niacin, magnesium, sodium, potassium, and vitamin E. When you consider the carbs in peanut butter, it still remains a nutrient-rich option.
        • Macronutrient ratio. With moderate protein and high-fat macronutrient breakdown, low carb peanut butter fits the ketogenic recommendations perfectly[*].
        • Great energy boost. The healthy fat content provides your body with the necessary calories to maintain sustained energy throughout the day without worrying about the extreme highs and lows that come with sugar highs and processed carbohydrates.
        • Abundant in monounsaturated fat. Studies have shown that these types of fats can help lower blood pressure, reduce "bad" LDL cholesterol, and even decrease cardiovascular risk.
        • Good source of fiber. Fiber has been shown to help lower the risk of stroke, obesity, gastrointestinal diseases, high cholesterol, and high blood pressure.
        • Keeps you full. Low carb peanut butter helps you stay satiated so you aren't constantly craving food in between meals. This helps you lose weight by eating fewer calories overall.

        Downsides of low carb peanut butter

        One primary concern of low carb peanut butter consumption on a ketogenic diet is the quality of the ingredients. Many commercial peanut butter brands in food stores contain harmful, inflammatory ingredients like hydrogenated oils and trans fats which have been proven to increase the risk of various health diseases.

        In fact, studies have shown that hydrogenated oils were linked to the increase in:

        If you’re looking for a low carb peanut butter option into your diet, we recommend avoiding commercial brands like Jif and Skippy because they tend to contain these added ingredients.

        Instead, stick to all-natural peanut butters without all of the unnecessary trans fats, hydrogenated oils, and sugars.

        Here are a few additional (potential) cons to peanut butter:

        • Easy to overeat. Since nuts are high in calories, it's very common to eat too much without noticing. In fact, just one extra tablespoon of peanut butter is approximately an additional 94 calories, which could easily exceed your daily calorie allowance!
        • Higher risk for pesticide contamination. Since commercial peanut crops are a part of big business, many farmers must use pesticides to prevent them from being destroyed. Peanuts also have a thin shell so all of the toxic pesticides have a higher chance of entering the peanut, but opting for higher-grade brands reduces this risk.
        • High in oxalates. Oxalate is an antinutrient which means it prevents certain minerals from being absorbed and used by your body. This can cause kidney stones in certain individuals who have large amounts of oxalate in the body.

        Best keto peanut butter brands

        In this list, we've highlighted brands that fit the keto bill, particularly those that can be described as low carb peanut butter. 

        We’ve excluded all products that add palm oil to their peanut butter. Companies add palm oil and other oils like grapeseed to create “no-stir” products, but there are a litany of environmental and public health issues with palm oil, and there are also nutritional concerns about cholesterol.

        While some companies do source better palm oil than others, it's still a loaded ingredient that we'd rather avoid. So if you'd also like to skip the palm oil, then opt for "stir" products. Sure, it's a bit of work, but it's worth knowing you're eating just peanuts!

        In your quest to find the best low carb peanut butter, it's crucial to remember that while many brands market themselves as "natural" or "keto-friendly", always check the nutrition facts and ingredient list to ensure you're making a keto-compliant choice.

        What about "classic" peanut butter brands?

        Now that you know the ideal options, what if your kid only likes Jif or you're out camping and someone whips out a jar of Skippy? These classic brands have a lot of product types but generally use added sugar and palm oil more than others.

        Although there are the other nutritional concerns we mentioned above, most brands that use distasteful additives are still keto-friendly from a net carbohydrate perspective.

        To save you some time, we've collected the most popular products from classic brands and rated their keto-friendliness. Our "Chomps Keto Score" is based on their net carb numbers and how many added ingredients they include, with 10 being the healthiest and 1 being the least.

        Note: Reese's Creamy Peanut Butter has more added ingredients than the other products listed here, which is why we’ve ranked it lower than the others.

        What about other nut butters?

        Variety is not only the spice of life, but it's also beneficial when it comes to nut butters, as different nuts contain different beneficial micronutrients. For instance, almonds are high in vitamin E, manganese, and magnesium, whereas cashews are high in vitamins E, K, and B-6.

        Whether your preference is  almond butter, cashew butter, or hazelnut butter, just remember that the same rules for low carb peanut butter apply. Be sure to review the ingredient list (the best nut butters have just 1 or 2 ingredients) and enjoy in moderation.

        The bottom line on keto peanut butter

        When eaten in moderation, peanut butter is a fantastic snack to add to your keto diet grocery list. But considering the variability in carbs in peanut butter across brands, it’s important to be aware of notable differences.

        We recommend sticking to all-natural peanut butters with just 1-2 ingredients, avoiding any brands that add in additional oils and sugars, and measuring out your snacking in tablespoons for the best results.
