Peanuts
2.10g net carbs per 1 oz
Roasted and lightly salted, a 1 oz handful brings 2.1 g net carbs, so they slot into a keto day fine in small portions. Easy to overeat by the bowlful though, and the carbs add up fast past a single serving, so measure them out instead of grabbing straight from the bag.

Good to Know
Technically a legume rather than a true nut, peanuts carry a slightly higher carb load than almonds or pecans, so the difference matters when you snack by the bowl. Reach for dry-roasted or raw and check the label, because honey-roasted versions and flavored mixes (think Planters honey roasted) can pack 5 to 8 g of added sugar per serving. Peanut butter is the bigger trap: many jars like Skippy and Jif slip in sugar, so look for ones whose only ingredients are peanuts and salt.
Is Peanuts Keto? The Full Answer
Peanuts contains 2.10g net carbs per 1 oz (4.50g total carbs minus 2.40g fiber). Roasted and lightly salted, a 1 oz handful brings 2.1 g net carbs, so they slot into a keto day fine in small portions. Easy to overeat by the bowlful though, and the carbs add up fast past a single serving, so measure them out instead of grabbing straight from the bag.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 11% of a 20g daily carb limit. Track your portions carefully and account for other carbs in your meals.
Better Keto Swaps
Macadamia nuts are the gold standard here. A 1 oz serving lands around 1.5 g net carbs while bringing a heavy dose of fat, so they fit a strict keto day better than peanuts. Pecans are another solid pick at roughly 1.2 g net carbs per ounce, with a rich, buttery taste that works for snacking or chopped over a salad. Want something more savory? Try Brazil nuts at about 1.4 g net carbs per ounce. Just keep the portion modest, since two or three nuts go a long way.
