Macadamia nuts have the highest fat content of any nut — 75.77 g per 100 g — and most of it is heart-healthy monounsaturated oleic acid, the same fat found in olive oil. At 718 kcal per 100 g they are extremely calorie-dense, yet their net carbs are remarkably low at just 5.22 g (13.82 g total carbs minus 8.6 g fiber). Macadamias are also rich in manganese (4.13 mg, about 180% DV) and magnesium (130 mg). They contain only about 1% water.

Variations
Raw macadamia nuts
718 kcal per 100 g — the default form. Highest monounsaturated fat content of any nut. Mild, buttery flavor. Best stored in the refrigerator due to high fat content.
Roasted & salted macadamia nuts
~716 kcal per 100 g — nearly identical calories to raw. Roasting slightly reduces water content. Main difference is sodium: ~300 mg per 100 g vs 5 mg in raw. Roasting enhances the buttery flavor but does not significantly change the macros.
Macadamia nut butter
~718 kcal per 100 g — same nutrition as whole nuts, just ground into a smooth, spreadable paste. No fiber loss during processing. Ideal for keto baking, smoothies, or as a spread. Store in the refrigerator — the high oil content can cause separation at room temperature.
Dietary Perspectives
For Weight Loss
Macadamia nuts are the most calorie-dense nut at 718 kcal per 100 g. A serving (28 g, about 10 nuts) has 201 kcal — and 10 nuts do not look like much. It is very easy to overeat. However, the high monounsaturated fat (59 g per 100 g) and fiber (8.6 g) provide strong satiety, and studies show nut consumption does not cause the expected weight gain. For weight loss, pre-portion into 28 g bags and never eat directly from the container.
For Athletic Performance
Macadamia nuts provide good magnesium (130 mg per 100 g) and manganese (4.13 mg, 180% DV), but their protein is low at 7.91 g compared to almonds (21 g) or peanuts (26 g). They are better as an energy-dense snack than a protein source. The monounsaturated fats support hormone production and recovery. One serving (28 g) provides a quick 201 kcal for endurance activities without digestive discomfort.
For Keto
Macadamia nuts are the number one keto nut — only 5.22 g net carbs per 100 g (13.82 g total carbs minus 8.6 g fiber). A serving (28 g) has just 1.5 g net carbs. The highest fat content of any nut (75.77 g per 100 g) makes macadamias ideal for hitting keto fat targets. Use them in keto baking, fat bombs, or eat plain as a snack. Much better than cashews (27 g net carbs) or pistachios (17 g net carbs) for keto.
Frequently Asked Questions
How many calories are in macadamia nuts?
A serving of macadamia nuts (28 g, about 10–12 nuts) contains approximately 201 calories. Per 100 g, raw macadamias have 718 calories — the highest of any common nut. A half cup (67 g) has about 481 calories. The calories come almost entirely from fat (75.77 g per 100 g), most of which is monounsaturated.
How much fat is in macadamia nuts?
Macadamia nuts contain 75.77 g of fat per 100 g — the highest fat content of any nut. About 59 g of that is monounsaturated fat (mainly oleic acid), the same healthy fat found in olive oil. Saturated fat is 12.06 g per 100 g. A serving (28 g) provides about 21.2 g of total fat. Despite the high fat, macadamias have zero cholesterol.
Are macadamia nuts healthy?
Yes — macadamia nuts are nutrient-dense. They provide 4.13 mg of manganese per 100 g (about 180% DV), 130 mg of magnesium, and 188 mg of phosphorus. The dominant fat is monounsaturated oleic acid, linked to improved cholesterol levels and heart health. They also contain 8.6 g of fiber per 100 g. The only downside is low protein (7.91 g) compared to other nuts.
Are macadamia nuts keto-friendly?
Macadamia nuts are the number one keto nut. Per 100 g they have only 5.22 g net carbs (13.82 g total carbs minus 8.6 g fiber). A serving (28 g) has just 1.5 g net carbs. Their extremely high fat content (75.77 g per 100 g) makes them ideal for hitting ketogenic fat targets. Compare with cashews (27 g net carbs per 100 g) or pistachios (17 g net carbs) — macadamias are far superior for keto.
Macadamia nuts vs almonds — which is better?
Macadamias: 718 kcal, 7.91 g protein, 75.77 g fat, 5.22 g net carbs per 100 g. Almonds: 579 kcal, 21.15 g protein, 49.93 g fat, 9.05 g net carbs. Almonds win for protein (nearly 3× more) and are less calorie-dense. Macadamias win for keto (half the net carbs) and monounsaturated fat content. Choose almonds for protein, macadamias for keto or maximum healthy fat.
How many macadamia nuts can I eat per day?
A recommended serving is 28 g (about 10–12 nuts, 201 kcal). This is a small handful — macadamias are extremely calorie-dense. Two servings (56 g) already add 402 calories. For weight management, pre-portion into 28 g bags and never eat from the jar. Studies show nuts do not cause expected weight gain when portions are controlled, thanks to strong satiety from fat and fiber.
