The ketogenic diet, defined by its low-carbohydrate, high-fat profile, requires careful selection of every food item, and nuts are no exception. While many nuts are celebrated for their healthy fats, their carbohydrate content can vary dramatically, making some highly suitable for keto while others should be enjoyed only in strict moderation. Selecting the right nuts for your keto journey can provide essential nutrients, boost satiety, and offer a delicious, crunchy snack that won't disrupt ketosis. This comprehensive guide breaks down the best nuts for keto, detailing their net carb counts, health benefits, and how to incorporate them into your daily diet.
The Top Tier: Lowest Net Carbs
For those seeking the lowest-carb nuts to maximize their daily carb allowance, these three stand out as the undisputed champions of the keto diet.
Macadamia Nuts: The Keto Champion
With their rich, buttery flavor and exceptionally low net carb count, macadamia nuts are a keto dieter's best friend.
- Net Carbs: Approximately 1.5g per 1-ounce (28g) serving, which is about 10-12 kernels.
- Nutritional Highlights: Macadamias are packed with healthy monounsaturated fats, which are excellent for heart health. They also contain manganese and antioxidants.
- How to Enjoy: Perfect as a simple snack, ground into a low-carb flour for baking, or as a base for creamy keto sauces.
Pecans: The Versatile Favorite
Pecans offer a delightful crunch and versatility with one of the lowest net carb counts of any nut.
- Net Carbs: Around 1.2g per 1-ounce (28g) serving, or about 19 halves.
- Nutritional Highlights: Pecans are a good source of zinc, manganese, and antioxidants, benefiting immune function and heart health.
- How to Enjoy: Snack on them raw, toast them for added flavor, or use them in keto-friendly baking and savory recipes, like a pecan-crusted chicken.
Brazil Nuts: The Selenium Powerhouse
Large and satisfying, Brazil nuts are another excellent low-carb option, prized for their uniquely high selenium content.
- Net Carbs: Roughly 1.2g per 1-ounce (28g) serving (about 6 kernels).
- Nutritional Highlights: Just one or two Brazil nuts can provide your daily selenium requirement, a mineral crucial for thyroid function and overall cellular health.
- How to Enjoy: Due to their potent selenium content, moderation is key. A few nuts per day is all you need for their maximum benefit.
Middle Ground: Moderation is Key
These nuts are still a great addition to a keto diet but have slightly higher net carb counts. Portion control is especially important to stay within your daily limits.
Walnuts: Brain-Boosting Omega-3s
Known for their distinctive brain-like shape, walnuts are a nutritional powerhouse, rich in omega-3 fatty acids.
- Net Carbs: Approximately 2g per 1-ounce (28g) serving, or about 14 halves.

Almonds: The Versatile Staple
A long-time favorite for healthy snacking, almonds are a versatile and accessible choice for keto diets.
- Net Carbs: About 2.9g per 1-ounce (28g) serving, or roughly 22 nuts.
- Nutritional Highlights: Rich in vitamin E, magnesium, and fiber, almonds support heart health and provide antioxidants.
- How to Enjoy: Eat them whole, use almond flour for low-carb baking, or enjoy almond butter on celery sticks.
Hazelnuts: The Creamy Treat
With a smooth, creamy texture, hazelnuts are perfect for satisfying cravings for sweeter flavors on keto.
- Net Carbs: Roughly 2.3g per 1-ounce (28g) serving.
- Nutritional Highlights: Hazelnuts are a good source of vitamin E and manganese.

Nuts to Limit or Avoid
While not off-limits entirely, these nuts contain significantly more carbs and can quickly push you over your daily carb limit on a strict ketogenic diet.
Cashews
These nuts are relatively high in carbs compared to other options. An ounce contains over 8g of net carbs, making them unsuitable for regular consumption.
Pistachios
With about 5g of net carbs per ounce, pistachios are another nut that should be enjoyed in very limited quantities on a keto diet.
