Understanding Net Carbs in Nuts
For those on a low-carb diet, it is essential to understand the concept of net carbs. Net carbs are the total carbohydrates in a food minus the fiber content. Fiber is a type of carbohydrate that the body cannot digest, so it does not raise blood sugar levels in the same way that other carbs do. Because nuts are generally high in fiber, their net carb count is often much lower than their total carb count, making many of them suitable for low-carb and ketogenic diets. However, as the total carbs and fiber content vary greatly between different types of nuts, so does the net carb count. This is why some nuts are much better for a low-carb diet than others.
The Best Low-Carb Nut Choices
When selecting nuts for a low-carb diet, prioritizing those with the lowest net carb counts is the best strategy. These nuts tend to be higher in healthy fats, which is beneficial for those following a ketogenic approach.
- Macadamia Nuts: These are widely considered the gold standard for low-carb diets. They are extremely high in healthy monounsaturated fats and have one of the lowest net carb counts of any nut. A one-ounce serving contains around 1.5 grams of net carbs.
- Pecans: Another excellent choice, pecans are not only delicious but also very low in net carbs, with approximately 1.2 grams per one-ounce serving. They are rich in antioxidants and healthy fats.
- Brazil Nuts: These are notable for their exceptionally low carb count and high selenium content. Just one or two Brazil nuts can provide your entire daily selenium needs. However, due to the high selenium concentration, it is important not to overindulge. A one-ounce serving has about 1.3 grams of net carbs.
- Walnuts: Known for their high omega-3 fatty acid content, walnuts are a nutritious and brain-healthy addition to a low-carb diet. They contain around 2 grams of net carbs per one-ounce serving.
- Hazelnuts: With a rich, sweet, and buttery flavor, hazelnuts are a great snack option. They contain approximately 2.3 grams of net carbs per one-ounce serving.
Nuts to Consume in Moderation
Some nuts have a slightly higher net carb content, but can still be included in a low-carb diet with careful portion control.
- Almonds: A very popular and versatile nut, almonds are suitable for most low-carb diets but contain a bit more net carbs than macadamias or pecans. A one-ounce serving has roughly 2.6 grams of net carbs.
- Peanuts (technically legumes): While technically a legume, peanuts are commonly consumed as a nut and can fit into a low-carb plan. They offer a good protein boost but are slightly higher in net carbs, with about 3.8 grams per ounce. Opt for natural peanut butter without added sugars.
High-Carb Nuts to Limit or Avoid
On a strict low-carb or ketogenic diet, some nuts are best avoided or consumed only in very small amounts to prevent exceeding your daily carb limit.
- Cashews: These are the highest-carb nut commonly eaten, with about 8 grams of net carbs per one-ounce serving. The carbs can add up very quickly, making them a poor choice for strict low-carb plans.
- Pistachios: With around 5 grams of net carbs per ounce, pistachios are another nut that should be limited on a strict low-carb diet.
- Chestnuts: These are a very starchy nut, containing a significantly high number of carbs compared to other nuts, making them unsuitable for most low-carb diets.

Tips for Including Nuts in a Low-Carb Diet
- Measure your portions: Because nuts are calorie-dense, it is easy to overeat them. Using a food scale or measuring cups can help keep portions in check and prevent unintended calorie and carb overconsumption. A typical serving is about one ounce (28 grams).
- Choose raw or dry-roasted nuts: Avoid nuts that are honey-roasted, glazed, or otherwise sweetened, as these contain added sugars and carbs that defeat the purpose of a low-carb diet.
- Use them as a healthy snack: A small handful of low-carb nuts can be a satiating snack between meals, thanks to their combination of healthy fats, protein, and fiber.
- Incorporate them into recipes: Nuts can be used to add flavor and texture to low-carb dishes. Try adding chopped nuts to salads, using nut flours for baking, or making a keto-friendly granola with a mix of low-carb nuts and seeds.
- Be mindful of nut butters: Always check the ingredients list on nut butters to ensure there are no added sugars. Look for products that contain only nuts and possibly salt.
Potential Downsides and Considerations
While nuts offer numerous health benefits, there are potential drawbacks to consider when incorporating them into a low-carb diet.
- High Calorie Density: Even the lowest-carb nuts are high in calories due to their high fat content. Overeating them, even in small amounts, can lead to weight gain if you are not careful with portion sizes.
- Risk of Overconsumption: The delicious and satisfying nature of nuts can make them very easy to binge on. For those struggling with appetite control, it might be better to limit or avoid nuts altogether.
- Selenium Toxicity from Brazil Nuts: As mentioned earlier, Brazil nuts are extremely high in selenium. While a few a day is beneficial, consuming too many can lead to selenium toxicity, causing symptoms like hair loss, brittle nails, and gastrointestinal issues. It is recommended to stick to just one or two per day.
Low-Carb Nut and Seed Recipes
- Spiced Mixed Nuts: Create your own keto-friendly spiced nuts by tossing a mix of almonds, pecans, and walnuts with olive oil and spices like chili powder, cumin, and a little salt. Toast them in the oven for a flavorful, crunchy snack.
- Keto Granola: Make a custom low-carb granola by combining crushed nuts (macadamias, pecans), seeds (flax, pumpkin), and a keto-friendly sweetener. Mix with melted coconut oil and an egg white for clusters, then bake until golden brown.
- Nut Flour Breads: Use almond or hazelnut flour as a substitute for high-carb flours in baking to create low-carb breads, muffins, and desserts.
Conclusion
In short, nuts can be a fantastic and nutritious addition to a low-carb diet, but the key is to be selective and practice portion control. The best choices are those lowest in net carbs, like macadamia nuts, pecans, and brazil nuts, while cashews and pistachios should be limited. By focusing on raw or dry-roasted varieties and using them mindfully, you can enjoy the many health benefits of nuts without derailing your low-carb efforts. Always be aware of the high calorie density and the potential for overconsumption to ensure they complement your diet effectively.
