How many carbs are in peanuts?
One ounce of raw peanuts (28g) has about 4.5g of carbohydrate and 2.1g of net carbs. The very high fat and protein content makes peanuts one of the lowest-net-carb snack foods.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 oz (28g) | 4.5g | 2.4g | 2.1g |
| 1 cup (146g) | 23.5g | 12.4g | 11.1g |
| 1 oz (28g) | 4.6g | 2.4g | 2.2g |
| 100 grams | 16.1g | 8.5g | 7.6g |
Net carbs
One ounce of peanuts has about 2.1g of net carbs, which is total carbs (4.5g) minus fiber (2.4g). Peanuts are unusual in that fiber makes up more than half of their total carb content, leaving very little net carb per serving. See the net carbs guide.
For diabetes
Peanuts are an excellent snack for people managing blood glucose. The 2.1g of net carbs per ounce has a negligible effect on blood sugar, and the high fat and protein content actually slow gastric emptying if peanuts are eaten alongside other foods, blunting spikes from the rest of the meal. A one-ounce handful is a practical snack that requires little or no insulin adjustment for most people. Salted dry-roasted peanuts and raw peanuts have similar carb counts. Watch added honey or sugar in flavored varieties. See the diabetes carb-counting guide.
Keto and low carb
Peanuts are one of the best keto snack options. One ounce has only about 2.1g of net carbs. Even two to three ounces stays within most keto daily budgets. The main concern on keto is total calorie intake, not carbs. Peanuts are high in omega-6 fats, so some keto practitioners prefer macadamia nuts or pecans as alternatives.
Good to know
Peanuts are technically legumes, not tree nuts, which is why people with tree nut allergies can sometimes tolerate peanuts (though peanut allergy is separate and extremely common). Boiled peanuts, popular in the American South, have a softer texture and slightly lower calorie density than dry-roasted, but the carb count is similar. Honey-roasted peanuts add about 5 to 6g of carbs per ounce from the coating. Dry-roasted peanuts have nearly identical macros to raw.

How many carbs are in peanuts?
One ounce of raw peanuts (28g) has about 4.5g of total carbs and 2.1g of net carbs after subtracting 2.4g of fiber.
Are peanuts keto?
Yes. One ounce has about 2.1g of net carbs, making peanuts one of the lowest-net-carb snacks. Even 2 to 3 ounces fits comfortably within a keto budget.
Are peanuts good for diabetics?
Yes, in normal portions. The 2.1g of net carbs per ounce has a negligible effect on blood sugar. The fat and protein also help slow digestion when peanuts are eaten with a meal.
Do dry-roasted peanuts have more carbs than raw?
Almost identically the same. Dry roasting does not meaningfully change the carb content. Honey-roasted or flavored varieties add carbs from the coating.
Are peanuts a nut or a legume?
Technically a legume, from the same plant family as lentils and beans. They grow underground rather than in trees. Despite this, their nutritional profile (high fat, high protein, low net carbs) is very similar to tree nuts like almonds.
