Standard smooth peanut butter. Natural varieties (just peanuts and salt) are nutritionally identical to commercial brands — the macro story is the same.

How does peanut butter fit your goals?

Most of the calories in peanut butter come from fat (16.4g per 2 tbsp (32g)), which makes it calorie-dense — easy to under-portion if you're eyeballing. Dietary fat is essential for hormone production and absorbing fat-soluble vitamins, but at 9 calories per gram it's also the macro most people accidentally over-consume when they stop weighing portions.

Diet-wise, peanut butter fits low-carb and vegan and vegetarian eating patterns.
