Is Peanut Butter Keto? Expert Answers and Alternatives

A fairly common question first-time ketoers ask is whether peanut butter is keto-friendly. The short answer is yes, peanut butter is keto-friendly. The long answer is - it depends on the type and brand.

Some peanut butters have added sugar and some even have partially hydrogenated vegetable oils – both forbidden on keto. Others are sugar-free and made mostly of peanuts. It’s easy to see why you will need to be careful when choosing peanut butter for your keto diet.

Continue reading to learn more about eating peanut butter on a keto diet. We will also talk about some peanut butter alternatives, which peanut butter brands are best for keto, and what recipes you should try.

Is Peanut Butter Keto-Friendly?

Peanut butter is definitely keto-friendly. Like most nut butters, peanut butter is high in fat, low in carbs, and moderate in protein. A 20-gram serving size of natural peanut butter has the following macros (according to

  • Carbs: 3g (10%)
  • Fat: 10g (74%)
  • Protein: 5g (16%)

The confusion around peanut butter on a keto diet stems mainly from two facts:

  • Peanuts are classified as legumes, and legumes are typically avoided on keto
  • Peanut butter often has added sugar

However, these features don't really make peanut butter any less keto-friendly. First, despite being a legume, peanuts are classified as nuts because their nutrient composition resembles that of tree nuts. Second, there are many peanut butters with no added sugar or sugar substitutes.


Carbs in peanut butter & other nutritional information

Only 10% of the calories in natural peanut butter come from net carbs, so you'll get around 3g net carbs per 2 tablespoons [1]. Peanut butters with sugar will give you 4.5g net carbs for the same serving size.

Besides being low in carbs, peanut butter is high in fat and moderate in protein — perfect on a keto diet. A 2-tablespoon serving will give you a generous 16g of fat and 8g of protein.

Other than that, peanut butter is a good source of vitamin E, B vitamins, magnesium, phosphorous, and copper.

Quick and easy better alternatives for low carb peanut butter

Not everyone loves peanut butter, and some people are even allergic to peanuts. Luckily, there are plenty of alternatives, some even nut-free. Check out these 4 popular substitutes for peanut butter in your keto diet:


Almond butter

Almond butter is a popular nut butter on keto. It is a natural nut butter with the same amount of net carbs as peanut butter [2]. A major advantage of almond butter is that it's lower in omega-6 fatty acids than peanut butter, and excess intake of omega-6 fats has been linked to obesity and other health problems [3].


Also known as sesame seed paste, tahini is another excellent source of protein and healthy fats. Keep in mind that tahini is on the runny side and it tends to be rather bitter on its own. However, added to dips, toasts, and smoothies, it makes everything taste better and much healthier.

Sunflower seed butter

In terms of flavor and texture, this seed butter is the closest you'll get to peanut butter. You can easily find it at most grocery stores and even make your own in a food processor.

Coconut butter

Coconut butter is a paste made from shredded coconut. It has an intense coconut-y flavor and is incredibly creamy. It's also rich in medium-chain triglycerides (MCTs).


How much peanut butter can I have on keto?

The keto diet typically limits net carbs to fewer than 50g daily. To eat within this daily carb limit, most of your meals should have fewer than 15 net carbs. A typical serving of natural peanut butter (2 tablespoons) provides around 3g net carbs. So, even if you double your intake, you'll still likely stay within your daily carb limit.

At the end of the day, how much peanut butter you can have on keto depends on whether it fits your macros. Make sure to count the carbs and other macros from peanut butter into your daily meal plan.
