Frequently Asked Questions
How many calories are in 2 tablespoons of peanut butter?
Two tablespoons (32g) of peanut butter contain approximately 188–191 calories, along with 16g of fat, 7–8g of protein, and 6g of carbohydrates. This is the standard serving size listed on all US nutrition labels.
How many calories are in 1 tablespoon of peanut butter?
One tablespoon (16g) of peanut butter contains roughly 94 calories — about half the standard serving. Spreading one tablespoon on toast or apple slices keeps the calorie count around 100.
Is natural peanut butter lower in calories than regular?
No. Natural and regular peanut butter have nearly identical calorie counts — around 188–191 per 2-tablespoon serving. Natural peanut butter simply skips added sugars and hydrogenated oils; it does not meaningfully reduce calories.
How many calories are in powdered peanut butter (PB2)?
Powdered peanut butter (such as PB2) contains about 45–60 calories per 2-tablespoon serving when mixed with water, versus 188 in regular peanut butter. The defatting process removes most of the fat and the majority of the calories.
Does peanut butter help with weight loss?
Peanut butter can support weight management when portioned carefully. Its combination of protein, fiber, and healthy fats promotes satiety. A 2020 review in Nutrients found that regular nut consumption was associated with lower BMI and reduced waist circumference, largely due to improved feelings of fullness.
