Quick Answer: The Best Nuts for Keto

The best nuts for a keto diet are pecans, macadamia nuts, and Brazil nuts. Each one has 1 to 1.5 grams of net carbs per ounce and 19 to 22 grams of healthy fat. They give you the fat-heavy, low-carb profile keto needs without spiking blood sugar or pushing you over the daily 20-gram carb cap [Healthline, 2024].

Why Do Nuts Work So Well on Keto?

A keto diet keeps net carbs under 20 to 50 grams per day. Nuts fit that math because most of their calories come from fat. According to a 2024 review in Nutrients, tree nuts average 70% of calories from fat, 15% from protein, and only 12 to 15% from carbs.

Nuts also help with the parts of keto people struggle with most. Research from Harvard T.H. Chan School of Public Health (2023) shows that adults who ate 1 ounce of tree nuts five days a week had 14% lower LDL cholesterol after eight weeks. Magnesium in almonds and pecans helps reduce the “keto flu” headaches and cramps reported by 25% of new keto dieters.

Data from the International Nut and Dried Fruit Council shows global nut consumption rose 4.7% year-over-year in 2025, with the keto market driving 38% of new product launches in the snack-nut category.

Top 8 Keto-Friendly Nuts Ranked by Net Carbs

1. Pecans — 1.2 g net carbs per ounce

Pecans take the top spot. One ounce (about 19 halves) gives you 1.2 grams of net carbs, 20 grams of fat, and 196 calories [Priester’s, 2024]. They are rich in zinc, manganese, and gamma-tocopherol (a form of vitamin E linked to lower inflammation markers).

2. Brazil nuts — 1.3 g net carbs per ounce

One ounce (6 to 8 nuts) has 1.3 g net carbs, 19 g fat, and 187 calories. Brazil nuts hold the highest selenium content of any food on earth — a single nut packs 96 mcg, well above the 55 mcg daily target. Cap intake at 2 per day, since selenium toxicity sets in above 400 mcg.

3. Macadamia nuts — 1.5 g net carbs per ounce

Macadamia nuts are the gold standard for fat-to-carb ratio: 1.5 g net carbs, 21 g fat, 204 calories per ounce [Hawaiian Host, 2024]. About 80% of their fat is monounsaturated — the same heart-healthy type found in olive oil. They are the #1 picked nut among keto recipe bloggers, per a 2025 Pinterest data report.

4. Walnuts — 2.0 g net carbs per ounce

One ounce (14 halves) provides 2 g net carbs, 18 g fat, and 185 calories. Walnuts are the only common nut with significant plant-based omega-3 ALA (2.5 g per ounce). A 2024 American Heart Association report linked daily walnut intake to a 9% drop in cardiovascular events.

5. Hazelnuts — 2.0 g net carbs per ounce

Hazelnuts deliver 2 g net carbs, 17 g fat, and 178 calories per ounce. They are loaded with vitamin E (21% of the daily value) and folate. Hazelnut flour is a top keto baking swap for wheat flour — it has 80% fewer carbs by weight.

6. Pine nuts — 3.0 g net carbs per ounce

Pine nuts offer 3 g net carbs, 19 g fat, and 191 calories. They contain pinolenic acid, which research from Tufts University (2023) suggests can trigger satiety hormones CCK and GLP-1, helping reduce appetite by up to 36% for four hours.

7. Peanuts — 3.8 g net carbs per ounce

Technically a legume, peanuts still earn a keto pass with 3.8 g net carbs, 14 g fat, and 161 calories. Buy dry-roasted and unsalted to skip seed-oil coatings and added sugars. Avoid honey-roasted versions, which can have 8 g of carbs per ounce.

8. Almonds — 2.6 g net carbs per ounce

Almonds give you 2.6 g net carbs, 14 g fat, 6 g protein, and 164 calories per ounce (about 23 nuts). They top the list for fiber (3.5 g) and vitamin E (37% DV). Almond flour, with 3 g net carbs per ¼ cup, is the #1 keto baking flour by US sales volume.

Which Nuts Should You Limit or Skip on Keto?

Three nuts hold too many carbs for a strict keto plan. According to registered dietitian Scott Keatley, RD (Keatley Medical Nutrition Therapy, NYC): “Cashews are heavier on the carbs and lighter on the fats, which isn’t a good match for a keto eater” [Delish, 2024].

• Cashews — 7.7 g net carbs per ounce. A handful (about 18 nuts) eats up nearly half your daily keto carb budget.
• Pistachios — 5 g net carbs per ounce. Fine in 10-nut portions, but easy to overeat.
• Chestnuts — 14 g net carbs per ounce. The most carb-heavy nut by a wide margin. Treat them as a starch, not a keto snack.

How Many Nuts Can You Eat Per Day on Keto?

Stick to 1 to 2 ounces (28 to 56 grams) per day. That looks like:

⏱️ Pro tip: Pre-portion nuts into 1-oz bags on Sunday night. A 2024 Cornell Food & Brand Lab study found pre-portioning cuts snack overeating by 27%.

What Do Experts Say About Keto Nuts?

Thomas DeLauer, certified nutrition coach and keto educator: “Macadamia nuts are number one. You get the highest fat ratio, the lowest carb load, and barely any inflammatory omega-6. They are basically built for keto” [Thomas DeLauer YouTube, 2024].

Dr. Stephen Phinney, MD, PhD, co-founder of Virta Health: Research data shows that adults on a well-formulated ketogenic diet who included 1 ounce of pecans daily kept ketone levels 18% higher than those who used cashews as a snack.

Lisa Moskovitz, RD, CEO of NY Nutrition Group: “Pecans and macadamia nuts are my top picks for clients on keto. Both stay below 2 grams of net carbs and bring the heart-healthy fats that lower LDL cholesterol over time.”

Case Study: A 90-Day Keto Nut Test

A 2025 case study published by Levels Health tracked 42 adults on a strict keto plan for 90 days. Half were assigned a daily 1-oz mix of pecans and macadamia nuts. The control group ate the same calorie count from cheese.

• -6.4 lbs Nut group lost an average of 6.4 pounds vs. 4.1 pounds in the cheese group.
• -12% LDL cholesterol dropped 12% in the nut group, compared with no change in the cheese group.
• 94% 94% of the nut group stayed in ketosis (blood beta-hydroxybutyrate above 0.5 mmol/L), vs. 81% in the cheese group.
• 3.2x Self-reported snack satisfaction was 3.2 times higher in the nut group [Levels Protein, 2025].

7-Day Keto Nut Snack Plan

Total weekly net carbs from nuts: ~25 g, leaving plenty of room for veggies and other keto foods within your daily 20-gram cap.

Keto Nut Trends to Watch in 2026

1. Macadamia milk surge. Sales jumped 41% year-over-year in Q1 2026, per SPINS retail data, as keto dieters swap almond milk for higher-fat options.
2. Sprouted nuts go mainstream. Whole Foods reported a 28% rise in sprouted nut SKUs since January 2026. Sprouting cuts phytic acid by up to 50%, boosting mineral uptake.
3. Single-serve packs grow 19%. Mintel forecasts 1-oz portion packs will lead nut category growth through 2027.
4. Cricket-protein nut bars. A small but growing 4% of new keto nut bars now blend insect protein with macadamia and pecans for added B12.
5. Mood-focused blends. Brazil-nut and walnut combos marketed for selenium and omega-3 mental-health benefits saw 33% growth on Amazon in 2025.
