The next time you’re at the grocery store, try playing this game. Pick up any can or jar of nut butter and read the ingredients. We bet that what you find will shock you.

In some cases, nuts are not even the first ingredient listed in nut butter. Most (if not all) store-bought nut butter contains some form of sugar as well as hydrogenated oils, which makes them a highly inflammatory food.

The ketogenic company Onnit saw a need to create a varieties of healthy nut butter that does not contain sugar or cheap oils. In addition to being free from these inflammatory ingredients,

Onnit fatbutter uses the highest quality of nuts with the most fat and fewest carbs to help fuel your ketogenic diet.

We reviewed the 4 different types of Onnit’s fatbutter in this article and why they are superior to your traditional store-bought nut butter. You might even consider making the switch to Onnit fatbutter even if you don’t follow keto!

Why Nut Butter?

Nut butters are extremely versatile and easy to use. They make a great addition to any diet as long as you’re not allergic to them. Spread some nut butter on some celery for a quick protein boost or add some to your favorite smoothies to enhance the creaminess.

The problem is that regular nut butters are loaded with preservatives to extend their shelf life and reduce the cost of the product. Peanut butter is the most common offender.

Food manufacturers use low-grade forms of GMO peanuts, which are already highly inflammatory. Then they add vegetable oil, sugar, and table salt to further contribute to its inflammatory effect on the body.

Onnit does not put vegetable oils or sugar in their butter. Instead, they use high-quality forms of nuts that are great for the ketogenic diet because they are high in fat and low in carbs.

Examples of nuts used in Onnit butter include Macadamia nuts, hazelnuts, cashews, and almonds. They also use organic coconut oil, pink Himalayan sea salt, organic hemp seeds, and organic chia seeds.

To sweeten the butter, Onnit uses a blend of keto-friendly no-calorie sweeteners such as stevia and erythritol.

They also use lucuma, which is a low-glycemic fruit native to Peru that is a good source of healthy fatty acids. It has a deliciously sweet flavor to naturally enhance the flavor of the butter while providing antioxidants to boost your health (1).

Unlike regular store-bought nut butter, all of the ingredients in butter positively contribute to your health. The fiber and healthy fats in the nuts help reduce inflammation and support numerous body systems.

Chia seeds, hemp seeds, and coconut oil also contain healthy fats, fiber and antioxidants that keep you slim, support your brain and digestive system, and lower blood sugar levels. Even the organic cinnamon in butter contributes to heart health by improving blood circulation (2).

onnit fatbutter review

Onnit makes 4 different delicious flavors of fatbutter. The first 2 choices (creamy peanut butter and salted almond butter) are great for keto because they are very low in net carb. The last 2 choices are relatively high in net carb per serving for a keto diet.

Here’s a breakdown of each.

#1. Creamy Peanut Butter

Onnit uses organic peanuts in its creamy peanut butter recipe. It’s non-GMO, gluten-free, and contains absolutely no sugars or sweeteners.

Peanuts are a legume, which falls in the gray area of the keto list because it’s high in carbs. However, Onnit mixes its peanut butter recipe with keto-friendly fats such as macadamia nuts, coconut oil, and organic chia seeds.

This helps keep the fat content up while keeping the carbs down. You still get the delicious taste of the peanuts, but cutting the recipe with other healthy fats helps keep you in ketosis.

We love that there are no added sugars or sugar sweeteners in this recipe whatsoever. Other products may contain no-calorie sweeteners, which may be hard to digest even though they don’t contribute to your overall carb content. This makes this recipe one of the cleanest peanut butter recipes we’ve seen.

Here is the nutritional breakdown of a 2-tablespoon serving of Onnit’s creamy peanut butter fatbutter:

  • 180 calories
  • 16 grams of fat
  • 5 grams of carbs (2 grams of net carbs)
  • 3 grams of fiber
  • 7 grams of protein

Ingredients: organic peanuts, macadamia nuts, organic chia seeds, organic coconut oil, pink Himalayan salt


  • Contains no added sugars or sweeteners
  • Provides 16 grams of fat and 2 grams of net carbs per serving

  • Provides 3 grams of fiber per serving to aid in digestive health
  • Super low in net carb


  • Peanuts might not be 100% strictly keto according to some people

#2. Salted Almond

Like the creamy peanut butter recipe, the salted almond butter does not contain sugar or sugar substitutes. It is a great option for those who have digestive problems and can’t handle sugar alternatives, even if they do not contain calories or carbs.

This fat butter recipe gets its healthy fats from macadamia nuts, almonds, chia seeds, and coconut oil. The chia seeds provide added fiber, which helps keep your blood sugar levels stable and aids in digestion. Fiber also helps keep you full so you eat fewer calories.

With five simple ingredients, this salted almond butter will replace your store-bought almond butter any day of the week. Two tablespoon  serving contains 15g of fat and 2 grams of net carbs, making it the perfect ketogenic food.

Here is the nutritional breakdown of a 2-tablespoon serving of Onnit’s salted almond fatbutter:

  • The combination of fat and fiber in this butter helps contribute to overall feelings of fullness so you eat fewer calories
  • Contains a versatile taste that can be added to numerous recipes (It goes great in smoothies!)


  • Because these butters contain no preservatives or additives, they are not as shelf stable as other nut butters. This means you can’t buy a bottle and store it in your pantry for months on end. You will want to use up this product quickly or refrigerate it after opening to keep it fresh.
