The role of nuts in a ketogenic diet
Nuts are a staple in many low-carb diets because they are packed with healthy fats, protein, and essential nutrients. For those on a ketogenic diet, nuts provide a convenient and satisfying way to boost fat intake while keeping carbohydrates low. They can aid in satiety, which is helpful for weight management and managing cravings. However, not all nuts are created equal in terms of their macronutrient profile. The key to success is to prioritize those with the highest fat-to-carb ratio and practice strict portion control, as even keto-friendly nuts are calorie-dense.
The best nuts for staying in ketosis
Certain nuts stand out as superior choices for the ketogenic diet due to their minimal net carbohydrate count. These options provide a nutrient-dense source of healthy fats without risking your state of ketosis when consumed in moderation.
Macadamia nuts: The keto champion
Macadamia nuts are arguably the most keto-friendly nut. With the highest fat content and one of the lowest net carb counts, they are a perfect fit for a high-fat diet. A single ounce delivers an impressive 21 grams of healthy fat, making them an excellent fuel source. Their rich, buttery flavor makes them a satisfying snack, and they are also a great source of monounsaturated fats that support heart health.
Pecans: A nutritional powerhouse
With just over 1 gram of net carbs per ounce, pecans are another top-tier choice for keto dieters. They are rich in healthy fats and packed with essential minerals like manganese and copper. Their low carb count and satisfying crunch make them incredibly versatile for both snacking and incorporating into recipes, such as low-carb desserts or savory dishes.
Brazil nuts: Rich in selenium
Brazil nuts are an exceptional source of selenium, a mineral vital for thyroid function and antioxidant defense. They are very low in net carbs, with approximately 1-2 grams per ounce. However, due to their potent selenium content, it is wise to consume them in moderation—typically just one or two a day is enough to meet your needs without overdoing it.
Walnuts and almonds: Great everyday options
Walnuts offer a good balance of fats, protein, and fiber, with about 2 grams of net carbs per ounce. They are especially noted for being a source of omega-3 fatty acids, which support brain health. Almonds, another versatile choice, contain slightly higher net carbs than the top contenders, at around 2-3 grams per ounce, but are an excellent source of protein, vitamin E, and magnesium. Both nuts can be enjoyed as a snack or used to make keto-friendly flours and butters.
Nuts to consume with caution
Some nuts contain higher net carb counts and should be consumed in smaller portions to avoid exceeding your daily carb limit and disrupting ketosis. This is especially important for those on a stricter ketogenic diet.
Cashews
Cashews are one of the highest-carb nuts, containing about 8 grams of net carbs per ounce. For someone aiming for 20-30 grams of carbs a day, a single serving can consume a large portion of the daily allowance. It is best to avoid them on a strict keto diet, or only consume a very limited amount occasionally.
Pistachios
Pistachios have a moderate carb count, at approximately 5 grams of net carbs per ounce. The main issue with pistachios is portion control; their small size makes it easy to overindulge and quickly exceed carb limits. They should be consumed sparingly.
Peanuts (a legume)
Although technically legumes, peanuts are often treated as nuts and can be keto-friendly in moderation. They contain about 4 grams of net carbs per ounce. Peanuts are higher in protein than many nuts, which can affect insulin response, and it is easy to overeat both peanuts and peanut butter.

| Brazil Nuts | ~1g | Exceptional source of selenium | Best Choice | 
| Macadamia Nuts | ~2g | Highest fat content | Best Choice | 
| Walnuts | ~2g | Good source of omega-3s | Good Choice | 
| Hazelnuts | ~2g | Rich in vitamin E | Good Choice | 
| Almonds | ~3g | Higher in protein and fiber | Good Choice | 
| Pine Nuts | ~3g | Source of pinolenic acid | Moderate Use | 
| Peanuts | ~4g | High protein, technically legume | Moderate Use | 
| Pistachios | ~5g | Easy to overeat; moderate carbs | Limited Use | 
| Cashews | ~8g | Highest in carbs | Avoid/Very Limited Use | 
How to incorporate nuts into your keto diet
Integrating nuts into a keto diet extends beyond simple snacking. They can be used to add flavor, texture, and a boost of healthy fats to many meals. Here are a few practical ways to incorporate keto-friendly nuts:
- Make your own nut butter: Blend macadamia nuts, pecans, or almonds into a smooth, homemade butter. This allows you to control ingredients and avoid added sugars common in store-bought versions.
- Create crunchy toppings: Chop walnuts, pecans, or almonds to sprinkle over salads, low-carb yogurts, or roasted vegetables for extra crunch and nutrients.
- Use nut flours for baking: Almond flour is a popular substitute for traditional flour in keto baking recipes for items like pancakes, muffins, and pizza crust. Hazelnut and macadamia nut flours can also be used.
- Add to keto granola: Mix low-carb nuts with seeds, coconut flakes, and a low-carb sweetener to create a satisfying keto granola.
- Combine in savory dishes: Use crushed pecans or almonds to create a keto-friendly crust for chicken or fish. Pine nuts are also an essential ingredient for homemade pesto sauce.
The importance of portion control
While nuts are a fantastic source of healthy fats on a keto diet, their high calorie density means portion control is paramount. Overconsuming nuts, even the low-carb varieties, can lead to an excess calorie intake that stalls weight loss, regardless of ketosis. A standard serving size is typically one ounce (28 grams), which is about a small handful. Using a kitchen scale to measure portions can help you stay on track with your daily macronutrient goals. Furthermore, avoid flavored or coated nuts, as these often contain hidden sugars.
Conclusion
Nuts can be an incredibly valuable and satisfying part of a ketogenic diet, providing healthy fats, protein, fiber, and essential nutrients. To get the most out of nuts while maintaining ketosis, focus on the low-carb champions like macadamia nuts, pecans, and Brazil nuts. Incorporate options like walnuts and almonds in moderation, and be mindful to limit or avoid high-carb nuts such as cashews and chestnuts. The key is mindful consumption and precise portion control to ensure you reap the benefits without derailing your dietary goals. By choosing the right nuts and managing your intake, you can enjoy a delicious and nutritious snack that supports your ketogenic lifestyle.
