Understanding the Carb Content of Cooked Liver
Cooked liver is renowned for its impressive nutritional profile, packing an array of essential vitamins and minerals. However, for those monitoring carbohydrate intake, such as individuals on a ketogenic or low-carb diet, its macronutrient composition is of primary interest. The good news is that liver is naturally very low in carbohydrates, with the exact amount varying slightly depending on the animal source.
Carbohydrate Breakdown by Liver Type
Different types of cooked liver offer distinct nutritional values, though all remain suitable for low-carb consumption. For example, a 100-gram serving of cooked beef liver contains approximately 4 to 5 grams of total carbohydrates. Conversely, cooked chicken liver is even lower, with some sources reporting less than 1 gram of total carbohydrates per 100-gram serving. This difference is notable for those aiming for the absolute lowest carb counts.
Since liver contains virtually no dietary fiber, the total carbohydrate count is also its net carb count. This is a significant advantage over many plant-based foods where fiber is subtracted from the total carbs to determine the net amount. The minimal carbohydrates present in liver are primarily in the form of glycogen, which is the storage form of glucose in animals and is largely depleted during storage.
How Cooking Affects Carbohydrate Content
Unlike starchy foods, the process of cooking liver does not alter its carbohydrate content in a meaningful way. What you add to the liver during cooking, however, can impact the final dish's carb count. For instance, recipes that use sugar or flour for breading will significantly increase the total carbohydrates. Simple cooking methods, such as pan-frying in butter or simmering with low-carb vegetables and herbs, will keep the dish's carb count minimal.
The Nutritional Powerhouse Beyond Carbs
While its low carb count is a major draw for some, liver is celebrated more for its rich profile of micronutrients. It is often referred to as 'nature's multivitamin' due to its high concentration of various vitamins and minerals.
- Vitamin B12: Liver is one of the single best dietary sources of this crucial vitamin, which is essential for red blood cell formation, brain function, and DNA synthesis.
- Iron: It provides a highly bioavailable form of iron (heme iron), which helps prevent iron-deficiency anemia.
- Vitamin A: As one of the richest sources of preformed Vitamin A (retinol), liver is vital for vision, immune function, and reproductive health.
- Copper: This mineral is abundant in liver and is important for energy production and iron metabolism.
- Folate: An excellent source of folate (Vitamin B9), which is key for cell growth and DNA formation.
Comparison: Beef Liver vs. Chicken Liver
| Macronutrient (per 100g) | Cooked Beef Liver | Cooked Chicken Liver |
|---|---|---|
| Carbohydrates | ~5.13 grams | ~0.87 grams |
| Protein | ~29.1 grams | ~24.5 grams |
| Fat | ~5.26 grams | ~6.51 grams |
| Calories | ~191 kcal | ~167 kcal |
As the table demonstrates, both types of liver are high in protein and low in carbs. Chicken liver is the clear winner for those seeking the lowest possible carbohydrate count, while beef liver offers a slightly higher protein content. The choice often comes down to personal preference for flavor and access, as both provide exceptional nutritional benefits.
How to Incorporate Low-Carb Liver into Your Diet
For those new to eating liver, starting with chicken liver can be a good entry point as it has a milder flavor. Cooking liver with strong, savory flavors can also help mask its distinct taste. Here are some simple, low-carb recipe ideas:
- Pan-fried with Onions: A classic recipe, simply fry sliced liver with onions in butter until cooked through. To keep carbs low, use a small amount of onion.
- Keto Liver Pâté: Blend cooked liver with butter, garlic, and herbs for a creamy, rich spread perfect for celery sticks or low-carb crackers.
- Hidden Liver Cubes: Blend raw liver into a purée and freeze in cubes. Add a cube to ground meat when making burgers or meatloaf for a nutrient boost without altering the taste significantly.

Conclusion
In summary, cooked liver is an extremely low-carbohydrate food, making it an excellent addition to most low-carb, keto, or carnivore diets. The amount of carbs is minimal and mostly in the form of residual glycogen, not fiber or sugar. Its true value, however, lies in its incredibly rich profile of vitamins and minerals, including Vitamin B12, iron, and Vitamin A. Whether you choose beef or chicken liver, incorporating this nutrient-dense organ meat in moderation can provide significant health benefits while keeping your carbohydrate intake in check.
Frequently Asked Questions
How many net carbs are in a cooked liver?
For cooked liver, the net carb count is essentially the same as the total carbohydrate count because it contains virtually no dietary fiber. For example, 100 grams of cooked beef liver has approximately 5 grams of net carbs.
Is liver good for a keto diet?
Yes, liver is an excellent food for a ketogenic diet due to its very low carbohydrate content and high protein, healthy fat, and micronutrient density.
Does cooking liver increase its carbohydrate content?
No, cooking liver does not increase its carbohydrate content. The final carb count of the dish depends on what ingredients, such as breading or sugar-based sauces, are added during preparation.
Is beef liver or chicken liver lower in carbs?
Chicken liver is typically lower in carbohydrates than beef liver. A 100-gram serving of cooked chicken liver contains less than 1 gram of carbs, while the same amount of cooked beef liver has around 4-5 grams.
Can people with diabetes eat liver?
Yes, people with diabetes can eat liver as part of a balanced diet, as its low carbohydrate content will not significantly impact blood sugar levels. However, due to its high cholesterol and vitamin A content, it should be consumed in moderation.
Does liver store toxins and are they passed to us when we eat it?
No, the liver does not store toxins. Its function is to filter and process toxins, but it does not accumulate them. Instead, it stores nutrients like vitamins and minerals, which is why it is so nutrient-dense.
What are some low-carb cooking methods for liver?
Some popular low-carb cooking methods include pan-frying in butter or tallow, braising with broth and herbs, or sautéing with low-carb vegetables like onions and peppers.
What are the main nutrients in cooked liver besides carbs?
Cooked liver is rich in protein, Vitamin A, Vitamin B12, iron, folate, and copper. It is considered one of the most nutrient-dense foods available.
