Ranking Nuts by Carb Content
Not all nuts are created equal when following a low-carb diet. Focusing on net carbs, which is the total carbohydrates minus fiber, is essential. Many popular nuts are not only low in net carbs but also rich in healthy fats, protein, and essential micronutrients. Careful selection and portion control can help incorporate these nuts without compromising dietary goals.
Pecans
Pecans are consistently at the top of the list as the lowest-carb nut. A one-ounce serving (about 19 halves) contains just over 1 gram of net carbs, making them a great option for a keto diet. Pecans offer a rich, buttery flavor and are a good source of monounsaturated fats, fiber, and antioxidants, such as ellagic acid. They also provide thiamine, magnesium, and zinc.
Brazil Nuts
Brazil nuts have a low carb count, with a one-ounce serving (around 6 nuts) containing 1.3 grams of net carbs. These nuts are known for their high selenium content. However, due to this high level, they should be eaten in moderation to avoid toxicity.
Macadamia Nuts
Macadamia nuts have a creamy texture and high fat content. With only 1.5 grams of net carbs per ounce, they are ideal for those following a keto diet. They also offer manganese and thiamine. Their fat profile may support heart health by regulating cholesterol and reducing inflammation.
Comparison of Nut Carbohydrates (per 1-ounce serving)
| Nut | Total Carbs (g) | Fiber (g) | Net Carbs (g) | Fat (g) | Protein (g) |
|---|---|---|---|---|---|
| Pecans | 3.9 | 2.8 | 1.1 | 20.4 | 2.6 |
| Brazil Nuts | 3.3 | 2.0 | 1.3 | 19 | 4 |
| Macadamia Nuts | 4.0 | 2.5 | 1.5 | 21.5 | 2 |
| Walnuts | 3.9 | 1.9 | 2.0 | 18.5 | 4 |
| Hazelnuts | 4.7 | 2.4 | 2.3 | 17 | 4 |
| Pine Nuts | 5.5 | 2.8 | 2.7 | 19 | 4 |
| Almonds | 6.1 | 3.2 | 2.9 | 14 | 6 |
Nuts to Moderate and Limit
While the above nuts are ideal for a low-carb diet, others require portion control or should be avoided entirely.
Moderate-Carb Nuts
Walnuts, hazelnuts, pine nuts, and almonds are valuable but have slightly higher net carbs. They offer significant nutrition, such as walnuts providing omega-3s, but moderation is key. Almonds, for example, are a great source of protein and Vitamin E, but their higher net carb count means they should be portioned carefully.
High-Carb Nuts to Avoid
Cashews and pistachios are higher in carbohydrates compared to low-carb options. Cashews, with approximately 8 grams of net carbs per ounce, can quickly use up a daily carb allowance on a strict keto diet. Pistachios also contain more carbs (about 5 grams of net carbs per ounce) and should be limited. Nuts that are honey-roasted, candied, or chocolate-covered should also be avoided due to added sugars.
The Role of Nuts in a Low-Carb Lifestyle
Incorporating nuts into a low-carb diet is easy and beneficial. Nuts serve as snacks, salad toppings, or additions to keto-friendly recipes. Choose raw or dry-roasted versions to avoid oils and carbs. Nut flours, like almond or macadamia flour, are excellent low-carb substitutes for traditional flours in baking. When buying nut butters, check the label for simple ingredients and no added sugars. Measuring portions is critical, as even the lowest-carb nuts are calorie-dense and can lead to overconsumption.
Conclusion
Pecans are the lowest-carb nut, with Brazil nuts and macadamia nuts as close contenders. These nuts offer the best fat-to-carb ratio and many nutrients. While other nuts can be included in moderation, limit or avoid high-carb options. Prioritizing low-carb nuts and practicing portion control helps enjoy a healthy diet.
Choosing the Best Nuts for a Keto Diet
For those on a keto diet, choosing the right nuts is important. Low-carb options such as pecans, macadamias, and Brazil nuts offer a high-fat profile. Walnuts are a good source of omega-3s but require moderation due to their higher carb content. High-carb nuts such as cashews and pistachios can interfere with ketosis and should be used sparingly.
Portion Control is Key
Even with low-carb nuts, portion control is essential. An ounce (about a small handful) is a standard serving size. Overeating can lead to exceeding your daily calorie and carb limits, potentially hindering weight loss progress.
Healthy Nut Incorporations
Nuts can be incorporated into low-carb recipes. Almond flour can be used as a substitute for wheat flour. Plain, unsalted nuts should be used to avoid excess sodium and additives.

Incorporating Nuts into a Low-Carb Diet
Nuts can be a versatile part of a low-carb diet. A single serving of pecans or macadamia nuts makes a quick snack. Sprinkle chopped walnuts or almonds over salads for texture and nutrients. Almond flour or ground macadamia nuts can be used to create low-carb treats. Homemade nut butter from low-carb varieties is a great way to avoid added sugars.

Why Some Nuts Are Better for Low-Carb Diets
The fat-to-carb ratio and the overall net carb count per serving determine the suitability for a low-carb diet. Pecans and macadamias are high in healthy fats and low in carbs, making them ideal. Nuts like cashews and pistachios have a higher starch content and a less favorable fat-to-carb ratio. Understanding this distinction helps individuals make informed choices to stay within daily carb limits.
