Is peanut butter a good source of protein?

Answered by Nikkiey Stott and her guests · Updated

The short answer

Not really. On The WarriorBabe Show, peanut butter is treated as a fat source with some protein, not a protein source. It's also an incomplete protein, so it won't build muscle the way eggs, chicken, fish or Greek yogurt do. Enjoy it, but don't count on it to hit your protein goals.

The full answer

Nikkiey explains on Ep. 338 that many women believe they're eating plenty of protein, then list oatmeal, rice and peanut butter. The problem is that peanut butter, almonds, avocado toast and chickpeas are incomplete proteins. They don't contain all nine essential amino acids your body needs, so on their own they aren't strong muscle-building proteins. That matters because muscle is what gives you the firm, toned look once body fat comes down. She points out that two women can eat the same calories and get very different results if one eats eggs, chicken, lean meat, Greek yogurt and fish while the other relies on oats, nuts, beans and granola.

In the Walmart grocery video, Maggie makes a related point: peanut butter is more of a fat source than a protein source. Her swap is powdered peanut butter, which has hardly any fat, tastes great with a little salt, and works in lots of high-protein, lower-fat recipes. She still uses a bit of regular peanut butter on rice cakes as a "macro topper" when she has a few carbs or a little protein left to hit at the end of the day.

None of this means peanut butter is bad. Nikkiey is clear that incomplete proteins are healthy and part of a balanced diet, and she eats them herself. The practical approach:

  • Build most meals around a complete protein first.
  • Layer foods like peanut butter, nuts, oats and beans on top.
  • Count peanut butter mainly as fat when you plan your day.
  • Try powdered peanut butter if you want the flavor with fewer fat calories.

If you've been eating "healthy" and not seeing results, this may be the gap. It's the plan, not you.

    Why do women need more protein as they get older?

    Women need more protein with age because they lose muscle every decade and their bodies get worse at turning protein into muscle, which Nikkiey calls anabolic resistance. To get the same muscle-building response as a younger woman, you need more protein, not less. Eating less to lose weight usually works against you.

    What is the difference between complete and incomplete protein?

    A complete protein contains all nine essential amino acids, the ones your body can't make and must get from food. An incomplete protein is missing one or more. Complete sources are mostly animal-based, like chicken, eggs, fish, Greek yogurt and whey. Incomplete sources are mostly plant-based, like nuts, beans, lentils and oats.

    Are protein bars a good way to get more protein?

    Not usually. Nikkiey says many bars, like Clif bars, carry only about 10 grams of protein from ingredients that don't give your body the amino acid profile it needs, and a daily bar costs $60 to $90 a month. Four hard-boiled eggs and a piece of fruit give more protein for about 50 cents.
