Peanut butter is a food staple that can be enjoyed as part of most eating plans, but can you eat just peanut butter for the keto diet? The short answer is no. While peanut butter is keto-friendly, it should be consumed in moderation and alongside other foods. Peanut butter is moderately low in carbs, containing 7 grams of total carbs and 5 grams of net carbs per 2-tablespoon (32-gram) serving. It's also high in calories, so if your goal for keto is weight loss, you need to be mindful of your portion sizes. To stay in ketosis, it's recommended to limit your daily carb intake to 40-50 grams, so a single serving of peanut butter uses 20% of your daily allotment. As such, it's important to carefully plan your other food choices and stick to plain peanut butter without added sugars.

What You'll Learn

Peanut butter is keto-friendly but watch your portions
Peanut butter is a versatile food that can be incorporated into most eating plans, including the keto diet. The keto diet is a low-carbohydrate, high-fat diet that promotes weight loss by changing the body's energy source from carbohydrates to fats. While peanut butter is keto-friendly, it is important to watch your portions and choose the right product.
Peanut butter is a good source of healthy fats, vitamins, minerals, fibre, and protein. However, it can be high in calories and relatively high in net carbs compared to other nut butters. A 2-tablespoon (32-gram) serving of peanut butter typically contains around 7 grams of total carbs and 5 grams of net carbs. This amounts to about 20% of your daily allotment of net carbs on a keto diet, which is typically limited to 40-50 grams per day. Therefore, it is important to be mindful of your portion sizes when including peanut butter in your keto diet.
When choosing peanut butter for the keto diet, it is best to select plain options without added flavours, sweeteners, or sugars. Natural, organic, or homemade peanut butter is ideal, as it ensures that you are only consuming peanuts and perhaps a pinch of salt. Some peanut butter brands may contain added sugars or honey, which can significantly increase the carb count. Additionally, be cautious when consuming other products made with peanut butter, such as candies, cakes, pies, or cookies, as these can be high in carbs.
While peanut butter can be a part of a keto diet, there are alternative nut butters that may be better suited. Almond butter, macadamia nut butter, hazelnut butter, and cashew butter are all excellent alternatives with lower net carbs per serving. These options can help you stay within your daily carb allotment while still providing the healthy fats, proteins, and minerals you need on the keto diet.
In conclusion, peanut butter can be a part of a keto diet, but it should be consumed in moderation and with careful planning of other food choices. Choosing plain, natural, or organic varieties without added sugars is ideal. Additionally, exploring alternative nut butters with lower carb content can be beneficial for staying within keto guidelines. Remember to always consult with a healthcare professional or registered dietician before starting any new diet or eating plan.

Peanut butter is high in calories
Peanut butter is calorie-dense, with 1 gram of fat containing 9 calories. A 2-tablespoon (32-gram) serving of peanut butter provides about 190 calories and 8 grams of protein. While peanut butter is high in calories, it is also nutrient-rich, containing healthy fats, protein, fibre, vitamins, and minerals.
The high protein content of peanut butter helps to increase feelings of fullness, curbing appetite and potentially reducing the urge to continue eating. This makes it a good option for those looking to lose weight, as it can help them consume fewer calories overall. Research indicates that consuming adequate protein is important for preserving muscle mass during weight loss efforts, as muscle is important for maintaining strength and preventing a slowdown in metabolism.
However, peanut butter's high-calorie content means that it can quickly add up, and consuming more than 3.5 ounces of peanut butter per day can provide the equivalent calories of a meal. Therefore, it is important to be mindful of portion sizes and consume peanut butter in moderation.
When purchasing peanut butter, it is recommended to choose products with minimal ingredients, such as ground peanuts and salt, and avoid those with added sugars, trans fats, and other unhealthy additives. Natural peanut butter with a layer of oil on top is a healthier option, and removing this oil can further reduce the calorie content.

Choose natural, unsweetened peanut butter
Peanut butter can be a part of a keto diet, but it is important to choose the right kind. Opting for natural, unsweetened peanut butter is the best way to go. This is because natural peanut butter tends to have fewer additives and preservatives, which can spike your blood sugar levels and kick you out of ketosis.
Unsweetened peanut butter is also free of added sugars, which can increase the carb count. While added sugar is not usually off-limits on the keto diet, it is important to limit it to stay within the recommended range. Natural, unsweetened peanut butter is also a good source of protein, which is important to get enough of while on a keto diet.
Some recommended brands of natural, unsweetened peanut butter include Crazy Richard's Pure PB, which contains just one ingredient—peanuts—and is free from added sugars, oils, and preservatives. Another option is Justin's Classic Peanut Butter, which contains just two ingredients: dry-roasted peanuts and palm oil. This brand is also free of added sugars and is committed to sustainably sourced ingredients.
When choosing a peanut butter for your keto diet, be sure to check the nutrition label for the net carb count per serving. While some peanut butters may be low in total carbs, they may contain added sugars or other ingredients that can affect your blood sugar levels.

Peanut butter is a good source of protein, fibre and vitamins
Peanut butter is a good source of protein, fibre, vitamins, and healthy fats. It is made from ground, roasted peanuts blended into a thick paste. Peanut butter is a versatile food that can be included in most diets, including the keto diet.
The keto diet is a low-carbohydrate, high-fat diet that promotes weight loss by changing the body's energy source from carbohydrates to fats. On a keto diet, it is recommended to consume around 40 grams of carbohydrates, 75 grams of protein, and 165 grams of fat per day. Peanut butter is a good source of protein, with 100 grams of peanut butter containing 22.5 grams of protein. It is also a good source of healthy fats, with two tablespoons of peanut butter containing about 16 grams of total fat.
In addition to protein and healthy fats, peanut butter also contains fibre and vitamins. A 100-gram portion of peanut butter provides many vitamins and minerals, including vitamin E, an antioxidant that has been shown to protect against Alzheimer's disease and age-related cognitive decline. Peanut butter also contains vitamin B, manganese, and resveratrol, which have been linked to a lower risk of chronic diseases like cancer and heart disease.
While peanut butter can be a nutritious and versatile food, it is important to consume it in moderation as it is high in calories. It is also important to check the labels when buying peanut butter, as many brands add ingredients like sugar, vegetable oil, and trans fats that can lower its nutritional value. Natural peanut butter, made with only peanuts and a pinch of salt, may be a healthier choice.

There are lower-carb alternatives to peanut butter
Peanut butter can be part of a keto diet, but it is best to stick to plain options without added sugar or extra sweeteners.

It has a higher concentration of nutrients per tablespoon, including more fiber, calcium, potassium, and monounsaturated fat. It also has a naturally sweet flavor, which can be satisfying when you crave something sweet.
- Sunflower seed butter is another option that has a similar texture to peanut butter. It provides more monounsaturated fat, magnesium, phosphorous, zinc, copper, and selenium. It is also a great alternative for people with peanut and tree-nut allergies.
- Soy nut butter is a cholesterol-free alternative that has less total and saturated fat than peanut butter. It is made from fresh roasted whole soybeans and is usually free of nuts, making it a good option for those with allergies.
- Cashew butter is one of the lowest fiber, highest carbohydrate nut butters. However, it is still keto-friendly and provides many essential vitamins and minerals, including magnesium, potassium, calcium, iron, and vitamins B-6, K, and E.
- Making your own nut butter at home is also an option. All you need is a powerful blender or food processor and your choice of nuts. This allows you to control the ingredients and avoid any added preservatives or sweeteners.
