Figuring out which foods are suitable for a very-low-carb, high-fat ketogenic diet can be tricky.

Many nuts and seeds are low in net carbs (total carbs minus fiber) and high in healthy fats, making them a perfect fit.

They’re also full of protein, fiber, vitamins, minerals, and antioxidants. Still, some varieties are lower in carbs than others.

Here are the 13 best nuts and seeds to fit your keto lifestyle.

Pecans are tree nuts with an excellent nutrient profile for keto. One ounce (28 grams) of pecans provides (1):

They’re a high-fat, keto-friendly nut that may help reduce levels of insulin.

Insulin is a hormone that can cause your body to store fat, so it’s ideal to keep insulin levels low when trying to lose weight.

In fact, a 1-month study in 26 adults found that those who ate around 1.5 ounces (43 grams) of pecans per day experienced reductions in insulin levels and improvements in insulin sensitivity, compared to the control group (2).

Pecans can be enjoyed on a keto diet as a snack or crushed and used as a crunchy, low-carb crust for fish or chicken.

Brazil nuts are a type of tree nut grown in South America. One ounce (28 grams) of Brazil nuts contains (3):

  • Calories: 185

One single Brazil nut provides more than 100% of your daily needs for selenium, making it an ideal way to get enough of this vital mineral in your diet (3).

Nonetheless, due to their exceptionally high selenium content, it’s best to limit your intake to one to three Brazil nuts a day to avoid consuming too much of this mineral, which may have negative health effects.

A 6-month study in 77 people found that those who consumed about 1 ounce (30 grams) of chia seeds for every 1,000 calories eaten daily experienced greater reductions in the inflammatory marker C-reactive protein (CRP) compared to a control group.

The same study showed that those who consumed chia seeds daily lost more weight and had greater reductions in waist circumference than the control group (9).

They’re also an excellent source of vitamin E, with a 1-ounce (28-gram) serving providing 28% of the Reference Daily Intake (RDI).

Vitamin E has been linked to a reduced risk of heart disease, as it acts as an antioxidant by neutralizing harmful free radical compounds, potentially reducing heart disease risk factors like high cholesterol (22, 23).

In a 4-week study in 48 adults with high cholesterol levels, consuming about 1 ounce (30 grams) of hazelnuts daily reduced total cholesterol while increasing HDL (good) cholesterol and vitamin E levels (24).
