So, if you're nuts about peanuts and don't want to give them up on keto, stick around. We're about to dive deep into how to make peanuts work on your keto journey.


  • Are peanuts keto-friendly? Yes, but only in moderation due to their higher carb content.
  • Peanuts have nutritional benefits but can disrupt ketosis if not carefully portioned.
  • Overconsumption of peanuts may increase the risk of experiencing keto flu symptoms.

Are Peanuts Keto-Friendly?

Peanuts, a popular snack and ingredient in many recipes, can be included in the ketogenic diet, but it is crucial to note that they should be consumed in moderation. With 7.63 grams of carbohydrates per 100 grams, peanuts fall into a gray area in terms of strict keto guidelines, which typically limit total daily carb intake to 20 grams.

Can You Have Peanuts on a Strict Keto Diet?

Including peanuts in a strict ketogenic diet, which typically limits daily carbohydrate intake to less than 20 grams, requires careful consideration and strict portion control. With their 7.63 grams of net carbs per 100 grams, peanuts could quickly use up a significant portion of your daily carb allowance if you're not careful.

For those on a less strict low-carb diet, where daily net carb intake ranges from 30 to 50 grams, incorporating peanuts into the diet is likely more manageable. However, regardless of which type of diet one follows, it's crucial to keep track of carb intake diligently to maintain ketosis.

Carbs In Peanuts

Peanuts contain 7.63 grams of net carbs per 100 grams, a value obtained by subtracting the dietary fiber content from the total carbohydrate content. These net carbs significantly impact blood sugar levels.

While peanuts do not fall into the low-carb category, they have a moderate glycemic index, which measures how quickly a food raises blood sugar levels. Foods with a low glycemic index (under 55) are digested, absorbed and metabolized slower, causing a lower and slower rise in blood glucose and, therefore insulin levels.

What Type of Peanuts Can You Have on Keto?

We're diving into the world of peanuts to see how different types stack up in the keto game. We'll look at their carb counts based on a typical serving size and rank them from best to worst for keeping those carbs in check. Let's crack into it:

  • Boiled Peanuts: These are surprisingly keto-friendly, with about 6 grams of carbs per serving. They're the lowest in carbs because the boiling process actually reduces their carb content, making them a great pick.
  • Dry Roasted Peanuts: Coming in with around 8 grams of carbs per serving, dry roasted peanuts are a solid choice for a keto snack. Just make sure they don't have added sugars.
  • Salted Peanuts: Similar to dry roasted, salted peanuts have about 8 grams of carbs per serving. The salt doesn't add carbs, so they're just as good a choice as their dry roasted cousins.
  • Spanish Peanuts: These have a bit more, at around 9 grams of carbs per serving. Their unique flavor makes them a tempting choice, but remember to keep an eye on portions.
  • Cajun Boiled Peanuts: With the added spices, Cajun boiled peanuts still keep it relatively low, at about 9 grams of carbs per serving. They add a kick without piling on the carbs.
  • Japanese Peanuts: These are a bit higher due to the crunchy coating, sitting at around 10 grams of carbs per serving. They're a treat, so best to enjoy them sparingly.
  • Honey Roasted Peanuts: These are at the top end for carbs, with about 12 grams per serving, due to the added sugars from the honey. They're delicious but should be consumed in moderation on a keto diet.

Remember, while some peanuts fit better into a keto diet than others, portion control is key. Enjoying them in moderation can allow for a variety of peanuts in your diet without derailing your carb count.

Health Implications of Peanuts on a Keto Diet

Incorporating peanuts into a keto diet can present some challenges in maintaining ketosis due to their relatively high net carb content. Overconsumption may lead to exceeding the daily carb limit of a ketogenic diet, subsequently disrupting the state of ketosis.

On the other hand, peanuts have several properties contributing to overall health. They are an excellent source of healthy fats, protein, and fiber, essential components of any balanced diet. They are also rich in various vitamins and minerals, including B-vitamins, magnesium, phosphorus, and manganese. However, while these nutrients are beneficial, peanuts also contain anti-nutrients like phytic acid, which can inhibit the absorption of some minerals in the body.

Incorporating Peanuts Into Your Keto Meal Plan

  • Portion Control: Since peanuts are keto-friendly in moderation, it's essential to measure your servings accurately. A small handful, equivalent to roughly one ounce or 28 grams, can be a good starting point.
  • Pair with Low-Carb Foods: Pairing peanuts with other low-carb foods can help keep your net carb intake in check. Try adding them to a salad with plenty of leafy greens, or use them as a crunchy topping on a keto-friendly stir-fry.
  • Keto Recipes with Peanuts: Peanuts can be a versatile ingredient in several keto recipes. Make an amazing Kung Pao Chicken with crushed peanuts!
  • Carb Counting: Incorporating peanuts into your keto diet underscores the importance of counting carbs. By staying aware of your daily carb intake, you can enjoy peanuts while maintaining ketosis.

Keto-Compatible Alternatives for Peanuts

  • Almonds: Almonds are a great alternative to peanuts on a keto diet. They are lower in carbs and high in monounsaturated fats, protein, and fiber.
  • Macadamia Nuts: Macadamia nuts are another excellent keto-friendly alternative. They are high in healthy fats and fiber but have fewer carbs than peanuts.
  • Pecans: Pecans are also a good choice for those on a keto diet. They contain fewer carbs than peanuts and are a good source of monounsaturated fats and fiber.
  • Flaxseeds: For those who prefer seeds, flaxseeds are a low-carb alternative to peanuts. They are rich in omega-3 fatty acids and fiber, making them a healthy addition to a keto diet.

Cast Iron Keto's Editorial and Research Standards

Certain rare or exotic food items may not have nutritional profiles in the FoodData Central database. If an exact match is not found in the FoodData Central database, then, the Cast Iron Keto team utilizes a three-prong approach to provide readers with the closest relevant nutritional data, where possible.

First, in the event that nutritional profiles for a rare or exotic food item is not available in the FoodData Central database, we investigate alternative names for that particular food item and use that data, when possible. Second, in cases where no alternate names exist, Cast Iron Keto will use nutritional data for a close relative or similar food item. Finally, if no close relatives or similar items exist, we refrain from publishing nutrient data tables.

When making dietary or health decisions based on FoodData Central's data, we suggest readers consult with a nutritionist or other health experts, particularly if the food in question has a significant role in your diet or if you are using the food item to treat any health disorder(s).

Furthermore, it is important to note that even if a close relative or similar item is used to approximate the nutritional data, different food items can have varying levels of nutrients due to factors such as soil quality, farming practices, and regional differences.
