Butter is a beloved staple in many diets, prized for its rich flavor and health benefits. The high-fat content of butter makes it popular among followers of low-carb, high-fat diets like the ketogenic diet. But is butter keto? Can it fit into a ketogenic lifestyle?
The keto diet, short for ketogenic diet, is a low-carb, high-fat eating plan that has become popular due to its potential weight loss and health benefits. It reduces carbohydrate intake and replaces it with fat, which causes the body to enter a state of ketosis. However, with so much conflicting information, it’s important to understand the role of butter in the keto diet.

What is butter?
Butter is made by churning fresh or fermented cream to separate the butterfat from the buttermilk. Traditionally, it was made by agitating cream in a butter churn, but most modern production uses industrial churning machines.
Butter comprises about 80% butterfat, 15% water, and 5% milk solids. The milk solids provide a small amount of lactose, protein, minerals, and fat-soluble vitamins. The deep yellow color comes from the carotenoid pigments in the cow’s diet.
What is the ketogenic diet?
The ketogenic diet, also known as the keto diet, is a low-carb, high-fat diet that aims to induce a state of ketosis in the body. The primary purpose of this diet is to help individuals lose weight and improve their overall health.
First, a quick primer on keto. The ketogenic or “keto” diet is a very low-carbohydrate, high-fat, moderate protein. By restricting carbs to around 5% of daily calories, the body switches from burning glucose to burning fat and ketones for fuel through a metabolic state called ketosis. Ketosis suppresses appetite while enhancing energy and mental clarity in many followers.
Allowed foods on the ketogenic diet include high-fat options such as avocados, nuts and seeds, cheese, butter, oils, and fatty meats. Low-carbohydrate foods, such as leafy greens and non-starchy vegetables, are also encouraged. However, foods high in carbohydrates, such as bread, pasta, rice, and sugary snacks, must be avoided.
Is butter keto friendly?
Butter is keto-friendly because it is high in fat and low in carbohydrates. It is considered a healthy fat on the ketogenic or low-carb diet. Along with other oils like olive, avocado, and coconut, butter is a popular choice for this lifestyle.
However, it is important to note that the keto diet includes more than just bacon and butter. In moderation, including low-carb vegetables, other healthy fats, eggs, fatty fish, meats, berries, and nuts and seeds is important.
Is clarified butter keto?
Clarified butter is well-suited for the ketogenic diet due to its high-fat content and the process of removing milk solids.
Clarified butter is made by heating butter to separate the milk solids from the fat. This process eliminates the lactose and casein found in regular butter, making clarified butter dairy-free and easier to digest for individuals who are lactose intolerant. The high-fat content of clarified butter is also ideal for the keto diet, which requires a significant reduction in carbohydrate intake and increased fat consumption.
The milk solids are skimmed off during the clarification process, leaving behind pure butterfat. This makes clarified butter almost entirely fat, with minimal traces of protein and carbohydrates.
For those following the keto diet, clarified butter provides several benefits.
Firstly, it is considered keto-friendly due to its low carbohydrate content and high fat composition. This makes it an excellent source of healthy fats essential for energy production and maintaining ketosis.
Secondly, clarified butter is considered suitable for the keto diet because it is free from milk solids, making it a suitable option for individuals with lactose intolerance or dairy allergies.
Butter nutrition facts
The macros and nutrition stats of butter depend on the cow’s diet, time of year, processing method, and more. Here is the nutritional profile of a typical salted butter:
1 Tbsp (14g) salted butter nutrition:
- Calories: 102
- Fat: 12g
- Carbs: 0g fiber, 0.06g sugar, 0.1g lactose = 0.16g total carbs
- Protein: 0.1g
- Vitamin A: 11% DV
- Vitamin D: 2% DV
- Vitamin K2: 1% DV
The most concentrated form of butter is ghee or clarified butter. By skimming off the milk fat and removing water and milk solids, you get pure butterfat with no carbs or protein.
1 Tbsp ghee nutrition:
- Calories: 112
- Fat: 13g
- Carbs: 0g
- Protein: 0g
As you can see, both regular and clarified butter are almost entirely pure fat, making them ideal for keto. But even with trace amounts, do the residual carbs in regular butter impact ketosis? Let’s analyze this closely.
Is butter a carb?
Butter primarily consists of milk fat, water, and milk solids. It undergoes a churning process that separates the fat from the liquid, resulting in the familiar solid form we know. This process removes most of the carbohydrates in the original milk, leaving very low levels in the final product.
For individuals following a low-carbohydrate or ketogenic (keto) diet, butter is often considered a suitable cooking fat. The keto diet emphasizes high fat intake and limits carbohydrate consumption. Butter’s high-fat content makes it an ideal option for keto dieters who wish to increase their fat intake and maintain the desired macronutrient ratio.
Regarding its classification, butter falls into the category of fats due to its predominantly fat composition. Fats are a concentrated source of calories, providing 9 calories per gram compared to the 4 calories per gram found in carbohydrates. This high energy content makes butter an excellent fuel source for individuals on the keto diet, where the primary goal is to achieve and maintain a state of ketosis, wherein the body relies on fat for energy rather than carbohydrates.
Analyzing carbs in butter on keto
While nutrition labels round down, testing shows regular butter contains around 0.1-0.5% carbohydrate by weight. The carbs come from milk sugars like lactose that remain bonded to butterfat and proteins after churning. Exact amounts vary by product and process.
On average, one tablespoon of butter provides 0.1-0.2g total carbs. Some European-style butters with higher fat and milk solid content can reach around 0.3g carbs.
Of the trace carbs in butter, about 70-75% come from lactose. Lactose is a disaccharide made of glucose and galactose bonded together. The remainder comes from traces of glucose and galactose.
How do these trace carbs impact ketosis?
First, lactose does not raise blood sugar levels directly like free glucose. The enzyme lactase must break it down into glucose and galactose before absorption. Those with lactose intolerance lack sufficient lactase enzymes to digest it properly.
For keto dieters who tolerate dairy, the lactose in butter is unlikely to impact ketosis since it does not provide direct glucose. The tiny amounts of glucose and galactose in butter may contribute negligible sugar.
Experts suggest that approximately 50% lactose carbs and 50-80% sugar alcohols like xylitol can be subtracted from total carb counts for their reduced glycemic impact.
Applying this principle to butter’s carb makeup of 70% lactose and 30% sugars means a significant portion of the already low 0.1-0.3g carbs per serving may be excluded from ketosis calculations.
What are the different types of butter?
Butter is a versatile dairy product used globally in cooking, baking, and as a spread. But not all butter is created equal. There are actually many different types of butter available, each with its own distinct qualities, flavors, and best uses. Here’s an overview of the most common butter varieties:
Regular/Salted butter – This is the most widely used standard butter. It is made from pasteurized cream and contains at least 80% milk fat. Some salt is added for flavor and preservation. Salted butter works well for everyday applications like toast, cooking, and baking.
Unsalted butter – As the name suggests, no salt is added to unsalted butter. It has a sweeter, purer dairy flavor preferred for baking and cooking where you want control over saltiness—often used in pastry recipes.
Whipped butter – Air is incorporated into whipped butter, making it lighter and fluffier in texture while reducing overall fat content slightly. Easy to spread straight from the fridge.
European-style butter – Popular in Europe, this butter has a higher fat content (82-86%) and lower water content than American-style. It is denser and richer in flavor. Excellent for spreading onto loaves of bread.
Grass-fed butter – Derived from cows fed grass rather than grain, grass-fed butter is higher in vitamins A and K2 as well as omega-3s. It has a richer yellow color and bolder flavor.
Ghee – Sometimes called clarified butter, ghee is slowly cooked to remove all milk solids and water, leaving only pure butterfat. It has a toasted, nutty flavor and lasts longer unrefrigerated.
Specialty Flavored butter – Compound butters mixed with herbs, spices, garlic, etc., are now popular. They add flavor when cooked with meat, seafood, vegetables, or baked goods.
With all the available options, everyone can find butter suited to their tastes, diet, baking needs, and health priorities.
What’s the best butter for keto?
Choosing high-quality, grass-fed butter is of utmost importance for a keto diet. Not only does it enhance the flavor and satiety of your meals, but it also offers numerous nutritional benefits that make it the best choice for keto.
Firstly, grass-fed butter has a higher nutrient profile compared to conventional butter. Cows that graze freely on grass produce butter with more vitamins and minerals. Grass-fed butter contains higher levels of fat-soluble vitamins like A, D, E, and K, which are essential for overall health and proper absorption of nutrients. These vitamins support the immune system, maintain healthy skin, and promote strong bones.
Moreover, grass-fed butter is richer in omega-3 fatty acids than conventional butter. Omega-3 fatty acids are beneficial fats linked to a reduced risk of heart disease, improved brain function, and reduced inflammation. Grass-fed butter contains a healthier ratio of omega-3 to omega-6 fatty acids, important for maintaining a balanced and anti-inflammatory diet.
In contrast, conventional butter, sourced from cows fed a grain-based diet, has a lower nutrient profile and omega-3 fatty acid content. The grain-based diet alters the fatty acid composition of the butter, leading to higher levels of omega-6 fatty acids, which can promote inflammation when consumed in excess.
How to use butter on keto
Butter is a keto dieter’s best friend. With its high-fat content and rich flavor, butter can make keto meals more delicious and satisfying. However, butter is still a calorie-dense food that should be used strategically within your keto plan. Here are some tips for harnessing the power of butter on a ketogenic diet:
- When cooking vegetables, sauté them in butter or finish them off with a pat of flavored butter. This adds richness without excessive calories.
- Make compound butters by blending butter with herbs, spices, garlic, etc. Spread on keto loaves of bread or use as a cooking fat. Get creative with ingredients!
- Use butter in moderation when making keto baked goods or fat bombs. Add a tablespoon or two to recipes, but avoid over-reliance.
- For coffee, limit bulletproof recipes to 1-2 tablespoons of butter maximum. Or opt for MCT oil or heavy cream instead.
- Clarified butter or ghee is ideal for cooking at high heat. The milk solids are removed so nothing burns.
- Spread butter on low-carb vegetable slices like cucumber, celery, or bell pepper for a quick keto snack.
- Add butter to a protein like chicken breasts, fish fillets, or steak after cooking for extra moisture and fat.
- Make simple sauces by melting butter and mixing herbs, spices, lemon juice, or other low-carb ingredients. Drizzle over vegetables.
- When dining out, ask for extra butter and dip keto-friendly bread or vegetables to amp up the fat.
With mindful portioning, butter can add flavor and satiety to keto meals without exceeding calories. Embrace butter as your low-carb cooking friend.
Is salted or unsalted butter better for keto?
When it comes to keto, both salted and unsalted butter can be consumed in moderation. However, there are some key differences to consider.
Salted butter, as the name suggests, contains added salt. This can enhance the flavor of dishes and add a savory element to your meals. On the other hand, unsalted butter is simply pure churned cream without any added salt.
In terms of keto, both options are suitable as they are high in healthy fats and contain negligible amounts of carbohydrates. However, the choice between salted and unsalted butter may depend on your sodium intake goals.
For individuals who are closely monitoring their sodium intake, unsalted butter is a better option. Salted butter typically has a higher sodium content compared to its unsalted counterpart. By choosing unsalted butter, you have more control over the amount of sodium you consume, which is particularly important for those with certain health conditions or high blood pressure.
Potential benefits of butter on keto
Butter is a nutrient-dense food that offers numerous health benefits. It is packed with vitamins and minerals, making it a valuable addition to any diet. One of the key nutrients found in butter is vitamin A, which plays a crucial role in maintaining healthy vision, immune function, and cell growth.
Butter also contains vitamin E, a powerful antioxidant that helps protect the body’s cells from damage caused by free radicals. Additionally, vitamin K2 is present in butter, which is important for maintaining bone health and helping to prevent heart disease.
Another notable benefit of butter is its content of conjugated linoleic acid (CLA). CLA has been found to have anti-inflammatory properties and may help reduce body fat, improve insulin sensitivity, and enhance immune function.
Furthermore, butter is a good source of omega-3 fatty acids, which are essential for brain health and reducing inflammation in the body. Omega-3 fatty acids have also been linked to improved heart health and a lower risk of chronic diseases.
Butter can be particularly beneficial on a ketogenic diet, where the primary fuel source is fat. By being high in healthy fats, butter can help maintain ketosis, a state where the body uses fat for energy rather than carbohydrates. This can lead to various benefits like improved cognitive function, increased energy levels, and better control of blood sugar levels.
Risks and considerations
The main health concern with high butter intake is its saturated fat content. While some studies link saturated fat to cardiovascular disease risk, the evidence remains contested. Recent research suggests dairy fat may be less risky than meat-based saturated fat.
Those with lactose intolerance may react poorly to even the small amounts of butter. Opt for ghee and monitor symptoms. Anyone with heart disease, diabetes, or cholesterol abnormalities should be extra cautious with high saturated fat intake and consider alternative fats.
Too much butter can also provide excessive calories, hindering weight loss. Monitor your goals and adjust your intake to maintain a sustainable calorie balance. Grass-fed butter has a healthier fat profile but costs substantially more.
Keto-friendly butter substitutes
Butter is a staple ingredient in many keto recipes. However, some people may need or want to avoid butter due to dairy allergies, lactose intolerance, or other dietary restrictions. Luckily, there are several excellent keto-friendly butter substitutes to try.
Ghee – Ghee, or clarified butter, is a butter with the milk proteins and sugars removed through heating and skimming. This leaves only the pure butterfat. Ghee has a rich flavor like butter but contains no lactose or carbs.
Coconut oil – With its high smoke point and mild coconut flavor, coconut oil makes an excellent substitute for spreading and cooking. Refined coconut oil has almost no coconut taste. Use virgin for flavor.
Avocado oil – Pressed from avocado flesh, this oil has a buttery texture and subtle flavor. It shines for high-heat cooking up to 500°F. The rich monounsaturated fats provide keto-friendly dietary fat.
Tallow and Lard – Rendered from beef or pork, these animal fats mimic butter’s rich taste and fatty acid content. Use for cooking and baking. Store-bought or make your own.
MCT oil – This oil is extracted from coconut and palm oils, providing concentrated medium-chain triglycerides. Mix into coffee or smoothies for an energy and cognition boost. No flavor.
Olive oil – Extra virgin olive oil has a grassy, peppery richness. Use in dressings and low-heat cooking up to 375°F. Not suitable for baking.
Duck fat – This animal fat has a savory, meaty flavor. Use for cooking eggs, vegetables, potatoes, and more. Adds moisture like butter.
There are many healthy, versatile options for replacing butter in keto recipes while avoiding dairy. Experiment to find the best dairy-free fats and oils for your needs.
Final thoughts
Butter fits perfectly into a ketogenic diet when used in sensible amounts to meet daily fat needs. The trace carbs are primarily indigestible lactose; standard servings provide under 1g net carbs. Clarified ghee offers pure fat with no carbs. While butter is keto-approved, people should consider their health status, ethical concerns, and cost preferences when choosing types. Use grass-fed and high-quality butters within your budget and macro allotments. Butter up your keto diet correctly and harness its potential benefits.
