Pecan Calories: Raw, Roasted & Candied Compared

How Many Calories Are in a Pecan?

An ounce of pecans, about 19 to 20 halves or a small handful, has roughly 196 calories. That makes pecans one of the more calorie-dense nuts, but almost all of those calories come from heart-healthy unsaturated fat, not sugar or starch.

Below, we break down calories by serving size, walk through the full nutrition label, compare raw pecans to roasted and candied versions, show how pecans stack up against other common nuts, and look at what clinical research actually says about pecans and weight.

Pecan Calories By Serving Size

Nearly 60% of the fat in pecans is monounsaturated and another 30% is polyunsaturated, leaving very little saturated fat. That fat profile is a big reason pecans are considered heart-healthy despite the calorie density.

Full Nutrition Label: Pecans (1 oz / 28g)

Here is the complete label for a standard one-ounce serving of raw pecans (about 19 halves), with percent daily values based on a 2,000-calorie diet.

The standout numbers here are manganese and copper. A single ounce of pecans covers roughly half your daily manganese needs, a mineral involved in bone formation and metabolic regulation, along with more than a third of your daily copper. Pecans are also cholesterol-free and virtually sodium-free, which is unusual for a snack food this calorie-dense.

Raw vs Roasted vs Candied Pecans: Calorie Comparison

How pecans are prepared changes the calorie count more than people expect, mostly because of added oil, butter, and sugar.

Candied pecans have the widest range because recipes vary so much. A light sugar glaze adds modest calories, while a thick praline-style coating with butter and sugar syrup can push a single ounce well past 250 calories, more than 50% higher than plain roasted pecans. Dry roasting barely changes the calorie count since no oil is added, while oil roasting adds 10-20 calories per ounce from the roasting oil itself, on top of any sodium from added salt.

Pecans vs Other Popular Nuts

Pecans are on the higher end of the calorie scale compared to other common nuts, per ounce:

• Cashews: about 155-157 calories
• Almonds: about 160-164 calories
• Pistachios: about 159 calories
• Walnuts: about 185 calories
• Pecans: about 196 calories
• Macadamia nuts: about 200-204 calories

Pecans have roughly 30 more calories per ounce than almonds, mainly due to a higher fat content. Protein tells a different story: almonds carry about 6g of protein per ounce, more than double the roughly 2.6g in pecans, so if protein is your priority, almonds edge out pecans even though pecans have more total calories. In exchange, pecans carry more monounsaturated fat, while walnuts stand out for their omega-3 content. WebMD’s nutrition overview notes that both nuts offer real health benefits, so the “best” choice depends more on your goals than raw calorie count alone.

What Does the Research Actually Say About Pecans and Weight?

Pecans have been studied more closely than most tree nuts when it comes to cardiometabolic health, and the results are fairly consistent. A randomized controlled trial from the University of Georgia, published in The Journal of Nutrition, had adults at risk for cardiovascular disease add or substitute about 68g of pecans daily for eight weeks. Both approaches led to meaningful drops in total cholesterol, LDL cholesterol, and triglycerides.

A larger 2025 trial in the American Journal of Clinical Nutrition followed 138 adults at increased cardiometabolic risk for 12 weeks, comparing a snack of 57g of pecans daily against a usual-diet control group. The pecan group again saw significant improvements in total cholesterol, LDL cholesterol, non-HDL cholesterol, and triglycerides, along with a higher overall diet quality score. It is worth noting honestly: body weight in that trial trended slightly higher in the pecan group (about 0.7kg over 12 weeks) compared to the control group, though the difference was not statistically significant. That is a useful reality check against claims that nuts are automatically weight-neutral regardless of portion size, and it reinforces why measured servings matter more than the “nuts are healthy so more is fine” mindset.

The likely mechanism behind the cholesterol benefits is the combination of monounsaturated fat, fiber, and plant compounds in pecans, which several studies link to better lipid profiles even when total calorie intake goes up slightly.

Where Pecans Come From

Pecans (Carya illinoinensis) are the only major tree nut native to North America, growing wild across the Mississippi River valley long before European settlers arrived. Native American communities harvested and traded wild pecans for centuries, and the word “pecan” itself comes from an Algonquian term describing nuts that need a stone to crack. Commercial pecan orchards took off in the southern United States in the late 1800s, and today Georgia, Texas, and New Mexico produce the majority of the U.S. crop. That southern connection is also why pecans show up so often in regional dishes like pecan pie, pralines, and pecan-crusted proteins, rather than being a general-purpose baking nut the way almonds or walnuts are used worldwide.

Buying and Storing Pecans for Fewer Wasted Calories

Pecan halves and pieces cost roughly the same per pound, so buying pieces is usually the better value if you plan to bake or cook with them rather than eat them whole. Because pecans are so high in unsaturated fat, they go rancid faster than more shelf-stable nuts like almonds if left at room temperature. Shelled pecans keep for about 3 months in a sealed container at room temperature, up to 9 months refrigerated, and roughly 1-2 years in the freezer without a meaningful change in taste or texture. Buying in bulk and freezing what you will not use within a few weeks is one of the simplest ways to avoid the temptation to finish an entire bag in one sitting, which is where most of the “hidden calorie” problem with pecans actually comes from.

How Pecans Fit Your Daily Calories

At about 196 calories per ounce, pecans work well as a satiating snack rather than a low-calorie filler food. If you are tracking toward a specific calorie or fat target, check your TDEE Calculator first, then use the calculator above to see how a handful fits your day. Since pecans are calorie-dense but nutrient-rich, they can be a smart addition even on a calorie-controlled plan, as long as portions are measured rather than eaten straight from a large bag.

If you are in a calorie deficit, pecans are easiest to fit in as a pre-portioned snack earlier in the day, since a measured ounce is filling enough to bridge a gap between meals. If you are trying to gain weight, pecans are one of the more efficient ways to add calories without adding much bulk to a meal, since a small handful adds nearly 200 calories.

Common Mistakes That Add Hidden Calories

• Eating straight from the bag without measuring, which often means 3-4 ounces instead of 1
• Choosing candied or honey-roasted versions without realizing they can run 50+ calories higher per ounce than plain
• Adding pecans to salads or oatmeal without accounting for the extra 150-200 calories they contribute
• Assuming “healthy fat” means unlimited portions, when a single cup of pecan halves runs about 750 calories
