Are pistachios keto? The short answer: yes, in moderation. However, the longer answer depends on your daily carb target, portion discipline, and whether you account for fiber. In fact, in-shell pistachios have a built-in advantage here — the cracking ritual naturally slows your eating pace, making it easier to stay within a serving.

Pistachio Nutrition: The Net Carb Numbers
Per 1 oz (~49 kernels, ~25 in-shell pistachios), the numbers break down as follows:
- Calories: 159
- Total carbohydrates: 7.7g
- Dietary fiber: 3g
- Net carbohydrates: ~4.7g
- Protein: 5.7g
- Total fat: 12.9g (primarily monounsaturated)
At ~4.7g net carbs per ounce, pistachios are indeed a moderate-carb nut — not the lowest, but notably high in fiber and protein relative to other snack options. Furthermore, the in-shell format means you naturally eat fewer kernels per session than you would with a pre-shelled bag, which helps manage the carb total in practice.

How Pistachios Compare to Other Low-Carb Nuts
Not all nuts deliver the same value on a low-carb diet. Here's how pistachios stack up:
- Macadamia nuts: ~1.5g net carbs/oz — the gold standard for low-carb snacking
- Pecans: ~1.2g net carbs/oz — lowest carb nut available
- Almonds: ~2.5g net carbs/oz — popular and widely available
- Pistachios: ~4.7g net carbs/oz — higher than the above, but stronger protein and fiber profile
- Cashews: ~7.7g net carbs/oz — the most carb-heavy common nut, harder to fit into strict low-carb plans
In contrast to macadamia nuts, pistachios carry more carbohydrates per ounce. That said, they deliver twice the protein and significantly more fiber, which makes them more satiating per serving. For strict keto (under 20g net carbs/day), one ounce fits comfortably. As a result, portion discipline matters more here than with lower-carb nuts.
Do FKN Nuts Spicy Flavors Fit a Low-Carb Diet?
Yes — and notably, FKN Nuts spicy flavors use dry spice blends — vinegar powder, dried pepper, herbs, and salt — with avocado oil as the base. None of these add meaningful carbohydrates. Additionally, there is no added sugar in any FKN Nuts flavor, which means the net carb count stays aligned with plain pistachios. Therefore, all three flavors — Devil's Dillight, Ghost Ranch, and Seoul Reaper — fit a low-carb eating pattern in a managed serving. Complete low-carb food list — Diet Doctor.

FAQ: Are Pistachios Keto?
How many net carbs are in one serving?
One ounce — roughly 25 in-shell pistachios or 49 kernels — contains approximately 4.7g net carbs after subtracting fiber. Specifically, that's about 23% of a strict 20g daily carb budget, or 16% of a more moderate 30g target.
How many calories are in 10 pistachios?
Approximately 32 calories per 10 shelled kernels — moreover, with less than 1g net carbs. Indeed, a 10-kernel portion is one of the lowest-impact nut snacks available on a low-carb plan.
Are Roasted Pistachios Keto?
No. Roasting does not meaningfully change carbohydrate content — in fact, the profile stays virtually identical. However, flavored or sweetened varieties can add carbs — specifically, honey-roasted pistachios carry significantly more sugar than plain or spice-seasoned varieties.
Can you eat pistachios every day on a low-carb diet?
Yes, with portion awareness. One ounce daily fits into most low-carb frameworks. Moreover, the regular fiber and protein from pistachios supports satiety, which helps reduce overall calorie intake throughout the day. The key is using in-shell format — consequently, the cracking process slows consumption and gives your hunger signals time to catch up. Read the full pistachio nutrition breakdown.
