The ketogenic diet is a high-fat, low-carbohydrate diet that promotes weight loss and improves heart health. While there are many sources of fats that can be consumed on a keto diet, not all fats are created equal. Some sources of fat, such as butter, are high in saturated fat, which can negatively impact cholesterol levels and heart health. Lard, on the other hand, is a rendered pork fat that contains both saturated and unsaturated fats. Unsaturated fats are generally considered healthier and can help lower cholesterol levels and reduce the risk of heart disease. In addition, lard is a good source of vitamin D, which offers further health benefits. Therefore, substituting lard for butter on a ketogenic diet may be a healthier option.

What You'll Learn

Lard is a good source of vitamin D
Lard, or rendered pork fat, is a great choice on a ketogenic diet. It has a high smoke point, which means it doesn't break down and oxidize as quickly as other fats, such as vegetable oil, that are commonly used in kitchens. When a fat doesn't oxidize as quickly, it creates fewer free radicals, which have been linked to inflammation and cell damage.
Pasture-raised pigs store vitamin D from the sun in their fatty tissues, which is why lard is one of the best natural, dietary sources of vitamin D, second only to cod liver oil. In addition to vitamin D, lard also contains vitamin B complex, vitamin C, and iron, as well as a high content of monounsaturated fats and "good" cholesterol, which are beneficial for cardiovascular health.
While lard is a good source of vitamin D, it's important to note that not all lard is the same. Leaf lard is considered the best kind, and it's important to ensure that the lard you consume is not partially hydrogenated. Additionally, when buying lard, consider purchasing it directly from a farmer or regenerative farm to support farming practices that humanely raise animals and put carbon back into the soil.
Lard is a versatile ingredient that can be used in various dishes, such as fajitas, pie crusts, doughs, and fried chicken or fish. It has a neutral taste, so it won't make your food taste like pork. However, it's important to consider the potential health impacts of consuming lard, especially concerning saturated fats and heart health. While lard is a good source of vitamin D, it may be best consumed in moderation as part of a balanced ketogenic diet that includes other healthy fats, such as olive oil, avocado oil, and butter from grass-fed cows.

Lard is more cost-effective than butter
When it comes to the ketogenic diet, the type of fat consumed is crucial. While butter is commonly used, lard, or rendered pork fat, is also an option and is considered more cost-effective for several reasons.
Firstly, lard is often cheaper than butter. In certain regions, butter can be relatively expensive, with a 250ml stick costing around $6. In contrast, lard is usually more affordable, making it a budget-friendly alternative for those on a ketogenic diet.
Secondly, lard is a versatile ingredient that can be used in various dishes without sacrificing taste. While butter is valued for its flavour, lard is favoured for its functionality, especially in baking. For example, lard is commonly used in pie crusts to achieve a flakier texture. Combining half butter and half lard in pie shells ensures both flavour and flakiness.
Additionally, lard is a good option for cooking eggs, as some people on ketogenic forums have attested. It provides the necessary fat for cooking without overpowering the dish's flavour.
Lard is also a healthier option than butter due to its higher content of monounsaturated and omega-3 fatty acids, which are beneficial for heart health. While both lard and butter contain about 115 calories per tablespoon, lard has a more favourable fatty acid composition.
However, it is important to note that the availability of pure lard may be limited, and it should be consumed in moderation as part of a balanced diet.

Lard has a high smoke point
When choosing a cooking fat, it is important to consider its smoke point—the temperature at which it starts to smoke. Every cooking fat, including butter, lard, and oil, has a smoke point. The smoke point of fats and oils depends almost entirely on their free fatty acid content, which increases during storage or use.
Lard, or rendered pork fat, has a high smoke point of 374 °F (190 °C). This is higher than the smoke point of butter, which is approximately 350 °F (177 °C). The higher smoke point of lard makes it a better choice for certain cooking methods that require high temperatures, such as stir-frying or searing. Using a fat with a lower smoke point for these cooking methods can lead to smoking, which not only affects the flavor and aroma of the food but also indicates the release of free radicals and acrolein, which are harmful to health.
In addition to its high smoke point, lard also has other advantages over butter. For example, lard is more cost-effective than butter, and some people may prefer the flavor of lard over butter.
However, it is important to note that while lard has a higher smoke point than butter, there are other oils and fats with even higher smoke points, such as avocado oil, which has a mild flavor and a smoke point of approximately 520 °F (271 °C). Therefore, when choosing a cooking fat, it is important to consider not only the smoke point but also the desired flavor and the availability of the fat or oil.

Butter is a processed product
Butter is a processed dairy product, made from cow's milk. The milk is stored in a cooled storage tank on a farm, and then transported to a dairy, where it is checked for quality. The next step in butter-making is churning, which can occur in either a batch or continuous process. During churning, the cream is transformed from an oil-in-water emulsion to butter, a water-in-oil emulsion. The cream is churned to encourage the fat globules to come together and form solid butter granules. As churning continues, a more solid structure is formed, and buttermilk is released and drained. The butter is then churned further until it is ready for packaging.
Butter is composed of milk fat separated from other milk components. It has a rich flavour and is widely used as a spread, as well as for cooking and baking. The process of making butter involves separating the cream from the milk. In the past, milk was left standing until the cream rose to the surface and was skimmed. Modern cream production involves a more efficient method called centrifugation.
The quality of the fat/lipid component of the starting cream is critical to the butter-making process. Two main reactions can occur with fat: lipid oxidation, which results in cardboard-like off-flavours, and hydrolytic rancidity, which results in baby vomit or soapy-like flavours. Therefore, quality metrics associated with these reactions should be included during cream testing.
Butter is composed of about 80-82% fat, 16-17.5% water, 1.5% salt, and 1% milk solids (vitamins, minerals, and lactose). While it is a simple product made from only a couple of ingredients, the physical changes that take place during butter production are complex.
When it comes to the ketogenic diet, some sources recommend using lard instead of butter. Lard, or rendered pork fat, is keto-friendly and can be a cost-effective alternative to butter. However, it is important to note that not all fats are created equal, and some are better for a ketogenic diet than others. For example, olive oil, avocados, nuts, and seeds are recommended as healthy fats to include in a keto diet.

Butter is a source of saturated fat
The American Heart Association recommends limiting saturated fat intake to less than 6% of total calories, while the Dietary Guidelines for Americans suggest less than 10%. This means that butter can be consumed in moderation, but it should be paired with other healthy fats from foods like nuts, seeds, olive oil, and fatty fish. Butter is also high in calories, with each tablespoon containing approximately 102 calories, so overconsumption can lead to a rapid increase in overall calorie intake.
While butter has been associated with weight gain and an increased risk of heart disease, some studies suggest that moderate consumption may have health benefits. For example, research has linked butter intake to a decreased risk of obesity, a lower risk of type 2 diabetes, and improved heart health. Butter also contains butyrate, a type of fat that may improve digestive health, decrease inflammation, and support weight control. Grass-fed butter, in particular, is higher in many nutrients compared to butter from cows fed processed grain-based feeds.
When considering the use of butter in a ketogenic diet, it is important to note that butters made from nuts and seeds, such as sunflower and almond butter, are recommended. These alternatives are low in carbohydrate levels and provide the body with healthy nutrients and fats. Additionally, lard, or rendered pork fat, is also a suitable option for cooking, as it is keto-friendly and cost-effective.

Frequently asked questions
A ketogenic diet is a low-carb, high-fat diet that aims to achieve a state of ketosis, where the body burns fat for energy instead of carbohydrates. This diet typically restricts total carbohydrate intake to less than 50 grams per day and emphasizes consuming 70-80% of daily calories from fats.
Lard, or rendered pork fat, is a good alternative to butter for those looking to reduce their saturated fat intake on a ketogenic diet. Lard contains both saturated and unsaturated fats, with unsaturated fats being heart-healthy and protective against issues like heart disease. Additionally, lard is a good source of vitamin D, which offers various health benefits, including reduced risk for chronic disease and type 2 diabetes.
Other healthy fat sources recommended on a ketogenic diet include olive oil, avocado oil, nuts and seeds, fatty fish, and coconut oil. These sources provide essential nutrients and help maintain a state of ketosis by supplying the body with healthy fats.
