For individuals committed to a ketogenic, low-carb, or sugar-restricted diet, finding a suitable milk substitute can be a challenge. Dairy milk contains a natural sugar called lactose, making it unsuitable for a zero-carb approach. However, the rise in popularity of alternative diets has led to a flood of new options, with some plant-based and dairy-based choices offering an excellent workaround. When you ask, "What kind of milk has no carbs or sugar?" the answer almost always points toward unsweetened plant-based beverages and specific high-fat dairy products.
The Best Plant-Based Options for Zero Carbs
The market for plant-based milks has expanded dramatically, and unsweetened versions are the key to a no-carb or low-carb lifestyle. These are made from nuts or seeds and are processed to retain minimal carbohydrate content.
Unsweetened Almond Milk
Unsweetened almond milk is arguably the most common and accessible zero-carb milk alternative. A single cup contains about 1 gram of net carbs, which is negligible for most keto dieters. It has a mild, nutty flavor and a thin, watery consistency. Many commercial brands are fortified with essential nutrients like calcium and vitamin D, but it's important to check the label for any hidden thickeners or emulsifiers that could affect the carb count.
Unsweetened Macadamia Nut Milk
For the ultimate zero-carb option, unsweetened macadamia nut milk is a top contender. It's richer and creamier than almond milk, making it a great choice for coffee or smoothies. It offers a higher fat content, which is a bonus for those on a high-fat, low-carb diet. Due to its higher production cost, it is often more expensive and less widely available than almond milk.
Unsweetened Flax Milk
Another excellent choice is unsweetened flax milk, which is made from flaxseeds. It is high in anti-inflammatory omega-3 fats and contains only about 1 gram of net carbs per cup. This makes it a great nut-free, low-carb alternative. Many brands also fortify it with vitamins like A, B12, and D, and minerals like calcium.
Unsweetened Coconut Milk Beverage
For those who love a tropical flavor, unsweetened coconut milk beverage can be a very low-carb option, often containing less than 1 gram of carbs per cup. However, it is crucial to distinguish this from the high-carb, canned coconut milk used for cooking. The beverage version is thinned with water and offers a light, tropical flavor profile perfect for smoothies or curries.
Dairy Options to Consider
While traditional dairy milk contains carbs, some high-fat dairy products can be used sparingly as a milk substitute for those on a very strict low-carb diet.
Heavy Cream and Half-and-Half
Heavy cream and half-and-half are extremely low in carbs, making them a popular choice for adding to coffee or sauces. One tablespoon of heavy cream has virtually no carbohydrates, as the fat content is high and the lactose is minimal. However, the carb count will increase with serving size, so moderation is key.

How to Choose the Best Zero-Carb Milk
- Read the Label Carefully: This is the most important step. Many brands add sugar, thickeners, or flavors that can dramatically increase the carb and sugar content. Always look for the word "unsweetened" and check the nutritional facts. The shorter the ingredient list, the better.
- Consider Your Use Case: The best choice depends on how you plan to use it. Unsweetened almond milk is a good all-purpose option, while macadamia nut milk is better for a creamy consistency in coffee. Coconut milk adds a unique flavor, and heavy cream is perfect for adding richness in small quantities.
- Check for Fortification: Some plant-based milks are fortified with vitamins and minerals often found in dairy, such as calcium and vitamin D. If you're switching from dairy, choosing a fortified version can help you maintain your nutrient intake.
- DIY Options: For complete control, you can make your own nut or seed milk at home using just nuts, seeds, and water. This ensures there are absolutely no hidden additives. Here is a simple, no-sugar recipe for homemade nut milk: https://www.healthline.com/nutrition/almond-milk-health-benefits
Conclusion
While truly zero-carb and zero-sugar milk is difficult to find in nature, unsweetened plant-based alternatives like almond, macadamia nut, and flax milk come extremely close. These products offer a way to enjoy creamy beverages and recipes without the carbohydrates or sugar found in traditional dairy milk. By carefully checking labels and choosing the right option for your needs, you can easily find a low-carb, sugar-free milk that fits your dietary goals. For the ultimate control, making your own at home is a simple and effective solution.
