Many people following a low-carb or ketogenic diet look for satisfying, nutrient-dense snacks that won't derail their carb limits. Nuts are a perfect fit, offering a high-fat, high-fiber, and moderate-protein profile. The key is understanding which varieties are truly low in net carbs—total carbohydrates minus fiber—and which should be limited due to a higher carb count.
The Best Low-Carb Nuts: Your Top Choices
Some nuts stand out as exceptionally low in net carbs, making them the best candidates for a low-carb eating plan. These can typically be enjoyed more freely, though mindful portioning is always a good practice due to their high-calorie density.
- Pecans: Often at the top of the list for low-carb nuts, pecans are a keto powerhouse with only 1.1 grams of net carbs per ounce. They are rich in heart-healthy monounsaturated fats, fiber, and important minerals like magnesium, thiamine, and zinc. Pecans' buttery flavor makes them an excellent snack or addition to keto desserts and savory dishes.
- Brazil Nuts: Famous for their extremely high selenium content, just one Brazil nut can meet your entire daily requirement. An ounce provides only 1.3 grams of net carbs. Given their potency, it's best to consume these in moderation (a few per day) to avoid selenium toxicity. They are also a good source of fiber, protein, and healthy fats.
- Macadamia Nuts: With a creamy, buttery texture and rich flavor, macadamia nuts are a favorite on low-carb and keto diets. They boast an impressive 1.5 grams of net carbs per ounce and are particularly high in monounsaturated fats. These fats are great for satiety and can help lower cholesterol levels.
Moderate-Carb Nuts to Enjoy in Moderation
This group of nuts still works well within a low-carb framework but requires slightly more attention to serving size. They provide valuable nutrients and should be incorporated thoughtfully into your daily carb count.
- Walnuts: Packed with heart-healthy omega-3 fatty acids (alpha-linolenic acid), walnuts are fantastic for brain and heart health. They contain about 2 grams of net carbs per ounce. Their rich, earthy flavor is perfect for salads or as a crunchy topping.
- Hazelnuts: These nuts are a good source of vitamin E and manganese and provide a pleasing, slightly sweet flavor. Hazelnuts have around 2.3 grams of net carbs per ounce.
- Almonds: Versatile and widely available, almonds offer a good balance of protein, fiber, and healthy fats. One ounce contains approximately 2.9 grams of net carbs. Almond flour and almond milk are popular low-carb alternatives.
- Peanuts: Though technically legumes, peanuts are treated as nuts in a culinary sense and are a viable low-carb option. They offer a great source of protein and have about 3.8 grams of net carbs per ounce. Choose natural peanut butter without added sugar to keep carbs low.
Higher-Carb Nuts to Limit or Avoid
Some nuts contain a higher concentration of carbohydrates and should be limited or avoided on a strict low-carb diet like keto. While still nutritious, their carb count can quickly deplete your daily allowance.
- Cashews: With around 8.3 grams of net carbs per ounce, cashews can be problematic for maintaining ketosis. Just a couple of handfuls can exceed a daily carb limit. They are best saved for occasional treats in very small portions.
- Pistachios: While delicious, pistachios contain approximately 5.0 grams of net carbs per ounce. This places them on the higher end of the spectrum for a low-carb diet, meaning they should be enjoyed sparingly and with careful portion control.

Tips for Incorporating Low-Carb Nuts into Your Diet
Successfully integrating nuts into a low-carb plan goes beyond simply choosing the right kind. Here are some strategies for mindful consumption.
- Portion Control is Key: Nuts are calorie-dense, and it's easy to overeat them. A standard portion is typically one ounce, or a small handful. Using a kitchen scale for accuracy can be a game-changer for staying within your macros.
- Choose Unsweetened Varieties: Always opt for raw, unsalted, or dry-roasted nuts. Avoid honey-roasted, sweetened, or heavily processed nuts, as these often contain significant amounts of added sugar.
- Read the Labels: Whether it's nut butter, nut flour, or pre-packaged trail mix, check the ingredients list. Many commercial products contain sneaky added sugars and unhealthy oils that aren't compliant with a low-carb diet.
- Use Them in Recipes: Nuts can add texture and flavor to a variety of low-carb dishes. Sprinkle chopped pecans on a salad, add walnuts to a low-carb brownie recipe, or use macadamia nuts to make a creamy, keto-friendly fat bomb. Nut flours, like almond flour, are excellent substitutes for high-carb wheat flour in baking.
- Make Your Own Nut Butter: Store-bought nut butter can sometimes contain additives. A simple way to avoid this is to make your own at home using a high-powered blender and your favorite low-carb nuts and a pinch of salt.
Conclusion
For those on a low-carb journey, nuts are an exceptional source of healthy fats, protein, and essential micronutrients. Pecans, Brazil nuts, and macadamia nuts offer the lowest net carb counts, making them the most ideal choices for strict low-carb and ketogenic diets. Moderate-carb options like walnuts and almonds are also excellent in smaller portions. By understanding net carbs, practicing portion control, and choosing unsweetened varieties, you can enjoy the many benefits of incorporating these nutritious and satisfying snacks into your daily eating plan.
