Are pistachios OK for low-carb diet?

Pistachios can be a great addition to a low-carb diet when eaten in moderation. Here’s a quick overview of the benefits and drawbacks of pistachios for low-carb diets:

Benefits of Pistachios for Low-Carb

  • High in fat and protein – Pistachios contain healthy fats and proteins that can help keep you feeling full between meals.
  • Low glycemic index – Pistachios have a low glycemic index, meaning they won’t spike your blood sugar levels.
  • Rich in nutrients – Pistachios provide vitamins, minerals, antioxidants and fiber that are important on low-carb diets.

Potential Drawbacks

  • High in calories – Pistachios are relatively high in calories. 1 oz provides 160 calories, so portion control is important.
  • Carb content – Pistachios contain about 8 grams of net carbs per ounce, which can quickly add up.
  • Easy to overeat – Pistachios are easy to consume in excess, which can unintentionally increase carb intake.

Are Pistachios Keto-Friendly?

Most low-carb diets like the ketogenic diet aim to limit net carbs to 20-50 grams per day. Here’s a look at whether pistachios can fit into a keto diet:

  • 1 oz serving has about 8 grams net carbs.
  • This represents a significant portion of the daily carb limit on keto.
  • Occasional, small servings can likely be accommodated.
  • It’s best to track net carbs to ensure staying within your limits.

So pistachios are not keto-friendly in large amounts but can be incorporated sparingly into a keto diet.

Pistachio Nutrition Facts

Here is the nutrition information for 1 oz (28g) of pistachios (source):

Calories 159
Fat 13g
Protein 6g
Carbs 8g
Fiber 3g
Net carbs 5g

As you can see, 1oz of pistachios contains 159 calories, 13g of fat, 6g of protein and about 8g total carbs with 3g of fiber. So the net carb count comes out to 5g per ounce.

Daily Pistachio Intake on Low-Carb Diets

The daily nut and seed intake will depend on your specific carb limits and calorie needs. Here are some general guidelines for including pistachios in a low-carb diet:

  • Keto diet: 1-2 oz per day
  • Moderate low-carb diet: 1-3 oz per day
  • High-carb days: Can increase serving size up to 1.5 oz per serving, a few times a day

Tracking your net carbs and calories can help determine a portion of pistachios that fits your diet. It’s ideal to weigh pistachios with a food scale for accuracy.

Tips for Eating Pistachios on Low-Carb Diets

Here are some tips to integrate pistachios into a low-carb diet:

  • Measure portions – Weighing pistachios helps control portion sizes and carb counts.
  • Count net carbs – Be sure to calculate net carbs when tracking your intake.
  • Pair with protein – Eat pistachios alongside protein sources to help control hunger.
  • Avoid roasted/salted – Choose raw, unsalted pistachios to limit sodium intake.
  • Buy in-shell – The shelling process can help slow down consumption.
  • Limit snacking – Set out a single serving to avoid overeating.

Health Benefits of Pistachios

Here are some of the top health benefits associated with pistachios:

  • Heart healthy fats – Most of the fat in pistachios comes from monounsaturated and polyunsaturated fatty acids that may improve cholesterol.
  • Antioxidants – Pistachios contain antioxidants like vitamin E, carotenoids, phenolic compounds, flavonoids and resveratrol.
  • Anti-inflammatory – Compounds in pistachios may help reduce inflammation.
  • Gut health – The fiber, protein and prebiotics in pistachios may support digestive and gut health.
  • Blood sugar control – Despite having carbs, pistachios have a low glycemic index and may help regulate blood sugar.

The nutrients and plant compounds in pistachios offer a range of potential health benefits. Incorporating them into a low-carb diet can provide nutritional variety.

Are Pistachios OK on Specific Low-Carb Diets?

Let’s look at how pistachios fit into some popular low-carb diet approaches:

Keto Diet

The keto diet limits net carbs to 20-50 grams per day. Pistachios can potentially fit into a keto diet in very small portions, but their carb content can quickly use up a large share of the daily allowance. Most keto dieters limit higher carb nuts and seeds or avoid them altogether.

Paleo Diet

The Paleo diet eliminates modern processed foods and focuses on ancestral whole foods. Pistachios fit into the Paleo diet since they are an unprocessed nut, though portion sizes still need to be watched.

Atkins Diet

The Atkins diet gradually increases net carb intake in phases. In the early induction phase, pistachios would need to be avoided. But small portions could be added back in the later phases as carb intake increases up to 100 grams per day.

South Beach Diet

The South Beach Diet is lower in carbs than a standard diet but not as strict as keto. The diet focuses on high-fiber, low-glycemic carbs. Pistachios can fit well into Phase 2 and beyond of the South Beach Diet in sensible portions.

Low-Carb High-Fat (LCHF)

LCHF diets emphasize high-fat foods as fuel sources. They are more flexible on carbs than keto. LCHF diets often encourage nuts and seeds for their high fat content, making pistachios a good occasional option.

Sample Low-Carb Pistachio Recipes

Here are some recipes incorporating pistachios into low-carb eating:

Pistachio Crusted Chicken

Coat chicken breasts with crushed pistachios mixed with almond flour, parmesan and spices then bake. The pistachios form a crispy, flavorful crust on the chicken.

Pistachio Pesto

Make pesto with pistachios, basil, olive oil and parmesan that can be served over zucchini noodles or used as a veggie dip. Much lower carb than traditional pesto.

Pistachio Energy Bites

Bind together pistachios, coconut, tahini, cocoa powder and your sweetener of choice for a tasty, nutrient-dense energy bite.

Pistachio Granola

A keto granola with roughly chopped pistachios, coconut flakes, pecans, almonds, cinnamon and nutmeg for a satisfying crunch.

Pistachio Butter

Make your own low-carb pistachio butter by blending shelled, roasted pistachios into a smooth spread to use like peanut butter.

Potential Downsides of Pistachios

Despite their health benefits, there are some potential downsides to pistachios to keep in mind:

  • High in calories, so portions need to be watched.
  • Contains a fairly high amount of net carbs compared to other nuts.
  • Very easy to overeat, especially salted/roasted varieties.
  • Some people may be sensitive or allergic to pistachios.
  • Higher in contaminants like aflatoxins compared to some other nuts.

While pistachios can be included on a low-carb diet, it’s best to enjoy them in moderation as part of a healthy, balanced approach.


Pistachios can be incorporated into a low-carb diet in reasonable portions. They provide a good source of healthy fats, plant-based protein, fiber and nutrients. However, pistachios are relatively high in net carbs compared to other nuts and seeds.

1-2 ounces per day may be able accommodate pistachios for some low-carb diets like keto. More liberal low-carb approaches can include slightly larger portions of around 1-3 ounces per day. Precise serving sizes can vary based on your total daily carb allowance.

Weighing pistachios, counting net carbs and pairing them with low-carb foods can help integrate pistachios into your diet. Avoiding overconsumption is important to minimize excess calories and carbs. Overall, pistachios can be a suitable occasional addition to low-carb eating when consumed mindfully.
