Peanut Butter For Bodybuilding: Overview

Calories In Peanut Butter

Peanut Butter varies in calories based on which variety we’re purchasing but overall the calories in peanut butter are between 180 to 200 calories per serving. 

Most of the time the serving size for peanut butter is 2 tablespoons, but not every brand adheres to this so it’s important to read the nutrition label to see what servings size the nutrition info is based on.

Peanut butter that is all-natural and contains only peanuts tends to be higher in calories. Those that are not natural and have added sugars tend to be lower in calories. This may be surprising to some, but we’ll discuss why this is.

This is a perfect example of products that are deemed “healthier” actually being higher in calories, than products that are said to be “not as healthy”. 

While calories certainly matter for changes in our body weight, it’s important to understand that just because a food is lower in calories does not mean it’s necessarily healthier.

Macronutrients In Peanut Butter

Peanut butter is primarily a source of fat because it contains more fat than it does protein or carbs. The amount of fat that peanut butter has will depend on if its a natural peanut butter or sweetened peanut butter.

The natural peanut butter will have more grams of fat than one that is sweetened. The natural peanut butter will have around 16 grams of fat in a serving (2 tbsp), while sweetened peanut butter will typically have fewer grams of fat in a serving. 

That being said, sometimes the fat content of sweetened peanut butter will be the same as natural peanut butter because the manufacturers sometimes add vegetable oil and/or trans fats to the product along with the sugar, which reduces the nutritional value of the product.

The sweetened peanut butter will have more carbs than natural peanut butter because of the added sugars, which increase the number of carbs in the peanut butter. So rather than having mostly fats in a serving, the sweetened variety will have an almost even mixture of fats and carbs.

This is why natural peanut butter can sometimes have more calories than sweetened varieties because fat has 9 calories per gram, and carbs only have 4 calories per gram. 

So per serving the natural peanut butter will have more calories, especially if the sweetened variety doesn’t have added vegetable oil.

Another important point is that peanut butter is often thought of as a protein, but it’s not as great of a source of protein as we may think because it only contains 8 grams of protein per serving.

Micronutrient Content Of Peanut Butter

Peanut butter has a moderate amount of micronutrients such as vitamin E, niacin, manganese, vitamin B6, and magnesium

These micronutrients are important but to get the most out of our micronutrient consumption, we should pair peanut butter with a fruit or a vegetable. 

Unless you’re a fan of celery and peanut butter or carrots and peanut butter (surprisingly tasty, trust me!), it will most likely be fruit that we pair it with. 

The natural varieties of peanut butter will be more micronutrient-dense than the sweetened varieties because the micronutrients in peanut butter come from peanuts, and the sweetened variety has fewer peanuts per serving than the natural ones.

3 Pros Of Eating Peanut Butter For Bodybuilding

The pros of eating peanut butter for bodybuilding are:

  • Peanut Butter Keeps Us Full
  • Peanut Butter Is Easy To Consume
  • Peanut Butter Is Versatile

1. Peanut Butter Keeps Us Full

A benefit to including peanut butter in our bodybuilding meals and snacks is that it will keep us full for longer, which is especially helpful when we’re dieting.

When we’re dieting we will be consuming fewer calories than our body burns per day and therefore it is common to be hungry throughout the day, but eating foods that digest slower and keep us full for longer periods can be very helpful.

Peanut butter can keep us full long enough to get us to our next meal with minimal discomfort, especially as our daily intake gets lower and lower.

2. Peanut Butter Is Easy To Consume

Peanut butter is extremely easy to consume and it can be easily incorporated into a meal or snack to increase the calories, which can be beneficial when we’re bulking.

Peanut butter is very easy to consume which can be a benefit when we’re bulking and we need to consume more calories than we typically would. 

It helps to have foods that are easy to consume in larger quantities, especially when we’re not particularly wanting to eat.

Finding foods that are easy to consume can make bulking or maintaining our weight a much more enjoyable process.

3. Peanut Butter Is Versatile

Peanut butter is versatile enough to go with many meals or snacks, which makes it a staple for bodybuilders who are often more concerned about hitting their macros than making a cohesive meal.

Having versatile products, like peanut butter, is a benefit to bodybuilders because sometimes to hit our macros we end up with some weird combinations of foods. So having foods that taste good with almost anything makes the process more enjoyable.

3 Cons of Eating Peanut Butter For Bodybuilding

The cons of eating peanut butter for bodybuilding are:

  • Peanut Butter Is High In Calories
  • Peanut Butter Servings Are Usually Overestimated
  • Peanut Butter Is Often A Binge Trigger For Dieting Athletes

1. Peanut Butter Is High In Calories

Peanut butter is higher in calories, which means it has more potential to affect our body weight and body composition.

For those who are bulking it could make life easier; but for those who are dieting, the calories could add up quickly.

We should be mindful about the number of calories that peanut butter has along with our serving sizes because although it does keep us full for longer, if we’re consuming enough of it that it takes away from other macronutrients (mostly protein), then it may be a problem.

We should always have our overall calorie goal in mind when bodybuilding is our priority so that we know if we’re overconsuming or under-consuming based on our goals.

2. Peanut Butter Servings Are Usually Overestimated

A serving of peanut butter is hard to estimate and is typically overestimated by most individuals, and therefore is easy to overconsume. To avoid this, we’re likely better off measuring out a serving size.

If we’re someone who can afford to consume a few more calories than planned, then this may not be an issue. 

However, if we’re in a dieting phase and we need to be more diligent about the calories and macronutrients we consume, then peanut butter can pose a problem if not measured.

3. Peanut Butter Is Often A Binge Trigger For Dieting Athletes

When bodybuilding athletes are severely restricted to get as lean as possible, peanut butter tends to be one of those foods that athletes will struggle to eat in moderation because their cravings are intense and most bodybuilders have it on hand.

Peanut butter is delicious and it’s a staple in most bodybuilding athlete’s diets, but it becomes a problem when athletes cannot control themselves around it. 

To be fair it’s not the peanut butter’s fault, but it is a downside to keeping peanut butter in the house because it can be too tempting for some bodybuilders.

It should be noted that it’s not necessarily the athletes’ fault either because they don’t intend to binge on peanut butter, but when our bodies reach a certain level of deprivation, it can result in intense cravings because we are physically hungry.

Can You Eat Peanut Butter Before Workouts? 

Peanut butter is high in fat which takes longer to digest, therefore it should be avoided 1 to ½ hours before working out. However, if we’re eating 2 to 3 hours before a workout it can be paired with protein, and carbs for a sufficient pre-workout meal.

We can eat peanut butter or any other fat before a workout as long as we’re giving it enough time to digest before the workout starts. 

If the fat has not been digested by the time we’re working out, we will likely experience some gastrointestinal distress, which makes training much less enjoyable. 

To avoid this, we should try not to consume peanut butter before a workout unless we’re consuming it 2 to 3 hours before training.

Can You Eat Peanut Butter After Workouts? 

We can eat peanut butter after a workout, as there is no harm in doing so. However, we should be aware that our priorities post-workout should be to consume more carbs and protein than fats.

After a workout, we need more protein and carbs to properly restore our energy levels and encourage muscle repair and growth.

If eating fats following a workout takes away from our protein and carb consumption, then we should avoid it. But if fats, like peanut butter, are incorporated with sufficient carbs and protein then there is no issue.

We asked Dietician Brenda Peralta about her thoughts on eating the classic peanut butter & jelly sandwich pre and post-workout and she stated that :

Brenda Peralta

“A peanut butter and jelly sandwich is an excellent way to increase your energy before a workout. Peanuts add some protein and healthy fats that will provide more sustainable energy. You can have this delicious treat 2-3 hours before training. After training could be an excellent option to replenish depleted glycogen stores. However, more protein needs to be added for optimum recovery.”

Does Peanut Butter Help Muscle Growth?

peanut butter help muscle growth

Peanut butter can help muscle growth because it helps us to consume more calories, and our body puts on muscle more readily when it has a surplus of calories to use for the muscle-building processes. However, we must also consume adequate protein.

Peanut butter by itself cannot cause muscle growth, but it can certainly help. To encourage muscle growth we would need to consume adequate protein throughout the day and provide a suitable training stimulus for our muscles.

The best recipe for success is a surplus of calories +  adequate protein intake + a periodized strength training program = muscle growth! 

Is It Okay To Eat Peanut Butter When Bulking? 

It is okay to eat peanut butter while we’re bulking because it is higher in calories, which will help us to reach our calorie goal for the day. However, it can also keep us full for longer so if we eat too much of it we may be too full to eat again.

The fat content of peanut butter helps provide excess calories which we need to bulk, but it also is slow to digest so it could keep us too full for too long. If we’re not hungry, it can make it more challenging to continue to consume the calories that we need to hit our calorie goal.

If we find it difficult to eat enough calories while bulking without getting overly full, then we may want to prioritize more carbohydrates than fats because carbs digest faster.
