Peanut butter is a staple in many households, loved for its creamy texture and rich flavor. It’s packed with healthy fats, protein, and essential nutrients, making it a popular choice for a quick snack or meal addition. But if you’re following a low-carb or keto diet, you might be wondering—is peanut butter low in carbs?
The answer isn’t as simple as a yes or no. While peanut butter contains some carbohydrates, the amount varies depending on the brand and ingredients. Some varieties include added sugars and fillers, increasing their carb count. Others, like natural peanut butter, are a better fit for low-carb lifestyles.
In this article, we’ll break down peanut butter’s carb content, its health benefits, and how to pick the best low-carb options. Keep reading to find out how you can enjoy peanut butter without going over your carb limit!
How Many Carbs Are in Peanut Butter?
Peanut butter is a delicious and nutrient-dense spread, but its carb content varies depending on the type you choose. The main difference lies in whether it contains added sugars and fillers, which can increase the total carbohydrate count.
Carb Breakdown Per Serving (2 tbsp):
- Natural Peanut Butter: ~4-5g net carbs
- Regular Peanut Butter: ~6-8g net carbs (due to added sugars)
- Powdered Peanut Butter: ~5-6g net carbs (lower in fat but contains added ingredients)
So, is peanut butter keto-friendly? Yes, but only if you choose the right type. Natural peanut butter, made with just peanuts (and sometimes salt), is the best option for those following low-carb or keto diets. Regular peanut butter often contains added sugars, which can quickly increase your daily carb intake.
To stay on track, always check the nutrition label and opt for peanut butter with minimal ingredients. Enjoy it in moderation, and you can still indulge in this creamy spread without exceeding your carb limits!
How Many Carbs Are in Peanut Butter?
Peanut butter is a nutrient-rich spread, but its carb content depends on the type. While peanuts are naturally low in carbs, many commercial peanut butter brands add sugar and fillers, increasing the total carb count.
Carb Breakdown Per 2-Tablespoon Serving:
- Natural Peanut Butter: ~4-5g net carbs (made with just peanuts and salt).
- Regular Peanut Butter: ~6-8g net carbs (contains added sugar and oils).
- Powdered Peanut Butter: ~5-6g net carbs (lower in fat, but may contain added ingredients).
So, is peanut butter keto-friendly? Yes, but only if you choose the right type. Natural peanut butter is the best choice for low-carb or keto diets, as it has fewer additives and a lower carb content. Regular peanut butter often contains hidden sugars, which can add unnecessary carbs to your diet.
To stay within your carb limit, read labels carefully and opt for peanut butter with minimal ingredients—ideally just peanuts and salt. When consumed in moderation, peanut butter can be a delicious and keto-friendly addition to your diet!
Best Low-Carb Peanut Butter Options
Choosing the right peanut butter for a low-carb diet can be tricky, as many brands add sugar and fillers. Here are the best options for keeping your carb intake low while still enjoying this creamy favorite.
1. Natural Peanut Butter
The best low-carb peanut butter is natural peanut butter, made with just peanuts and salt. Unlike regular peanut butter, it contains no added sugars or hydrogenated oils. A typical serving (2 tbsp) has around 4-5g net carbs, making it a great choice for keto and low-carb diets.
2. Powdered Peanut Butter
If you’re looking for an even lower-calorie option, powdered peanut butter is a great alternative. It has about 5-6g net carbs per serving, but since it’s lower in fat, it’s best used in smoothies, baking, or mixed with water for a peanut butter spread. Make sure to check the label, as some brands add sugar.
3. Almond or Macadamia Butter
If you’re open to alternatives, almond and macadamia butters have even fewer carbs than peanut butter. Almond butter contains 2-3g net carbs per serving, while macadamia butter is even lower. Both provide healthy fats and are great for those following a strict keto diet.
4. What to Avoid
Steer clear of peanut butter brands that contain:
❌ Added sugars (cane sugar, corn syrup, honey).
❌ Hydrogenated oils (which add unnecessary trans fats).
❌ Flavored varieties (chocolate, maple, or cinnamon often have extra carbs).
To stay low-carb, always read ingredient labels and choose brands with minimal, whole-food ingredients. A high-quality, sugar-free peanut butter can be a delicious and healthy part of your diet!
Health Benefits of Peanut Butter on a Low-Carb Diet
Peanut butter isn’t just delicious—it also packs several health benefits that make it a great choice for low-carb eaters. When consumed in moderation, it can support satiety, digestion, and overall nutrition.
1. High in Healthy Fats and Protein
Peanut butter is rich in monounsaturated and polyunsaturated fats, which promote heart health and help keep you full for longer. Plus, with about 8g of protein per serving (2 tbsp), it supports muscle maintenance and reduces cravings—an important factor for those on a low-carb or keto diet.
2. Rich in Fiber
With 2-3g of fiber per serving, peanut butter aids digestion and helps regulate blood sugar levels. Fiber slows the absorption of carbs, preventing spikes and crashes in blood sugar, making it beneficial for those following a low-carb lifestyle.
3. Packed with Essential Nutrients
Peanut butter is a nutrient powerhouse, providing:
✔️ Magnesium – Supports muscle function and energy production.
✔️ Vitamin E – Acts as an antioxidant to protect cells from damage.
✔️ B Vitamins – Aid in energy metabolism and brain function.
4. A Keto-Friendly Addition (in Moderation!)
While peanut butter is low in carbs, portion control is key. Sticking to 1-2 tablespoons per serving ensures you stay within your daily carb limit while reaping its nutritional benefits.
