The dairy aisle presents a challenge for individuals on low-carb, keto, or sugar-conscious diets. While traditional cow's milk is common, its carbohydrate content, derived from lactose, can add up. Fortunately, a growing variety of plant-based milks and dairy alternatives cater to low-carb lifestyles. Always choose the unsweetened version and read the nutrition label carefully, as sugar content varies significantly between brands.
The Best Low Carb Milk Options
For the lowest carb options, unsweetened nut and seed milks are the best choices. These alternatives provide a creamy texture and flavor with minimal impact on your carbohydrate count. Always check the packaging for 'unsweetened' to avoid hidden sugars.
Macadamia Milk
Unsweetened macadamia milk often contains less than 1 gram of carbs per cup. It provides a creamy, nutty flavor and works well in coffee, smoothies, or low-carb recipes. Its smooth texture and richness make it a good dairy substitute.
Hemp Milk
Unsweetened hemp milk, made from hemp seeds, is another low-carb choice, with around 1.3 grams of carbs per cup. It is also a good source of omega-3 fatty acids. Its earthy, nutty flavor is subtle and can be used in many dishes and beverages.
Almond Milk
Unsweetened almond milk typically has 1 to 2 grams of carbs per cup. Its mild flavor and thin consistency make it a versatile dairy substitute. Always check the label, as sweetened versions contain significant amounts of sugar, drastically increasing the carb count.
Cashew Milk
Unsweetened cashew milk is another nut-based alternative that is very low in carbs, with about 1 to 2 grams per cup. It tends to be creamier than almond milk, making it good for lattes and creamy sauces.
Flax Milk
Unsweetened flax milk offers a low-carb alternative, with approximately 2 grams of carbs per cup. It is known for providing healthy omega-3 fatty acids and has a mild, nutty flavor.
Coconut Milk (Beverage)
For low-carb coconut milk, choose the beverage sold in cartons instead of the canned version. Unsweetened coconut milk beverage contains a low carb count of about 1 to 3.4 grams per cup. It provides a distinct, sweet, nutty flavor, popular in smoothies and some culinary applications.

Milks to Limit or Avoid
Knowing which milks to avoid is important for following a low-carb diet. These options can easily push you over your daily carbohydrate limit.
Cow's Milk
All cow's milk contains 12 grams of carbohydrates per cup due to lactose, regardless of fat content. This makes it unsuitable for low-carb or keto diets. Goat and sheep milk contain similar levels of natural sugar.
Oat Milk
Oat milk is high in carbohydrates, with unsweetened versions typically containing 9 to 17 grams per cup. Because oats are a grain, this is expected, and it makes oat milk a poor choice for low-carb lifestyles.
Rice Milk
This beverage is high in sugar and carbohydrates, with about 22 grams per cup. Rice milk should be avoided if you want to minimize your carb intake.
Tips for Choosing the Right Milk
Making the right choice involves more than just checking a general list. Here are a few practical tips:
- Read Labels Carefully: Check the nutrition facts for the exact carbohydrate and sugar content per serving.
- Beware of Hidden Sugars: Sweetened or flavored versions of even low-carb milks often have added sugar. Always choose the plain, unsweetened variety to stay on track.
- Consider Additives: Some plant-based milks use thickeners that can contain hidden carbs. Look for products with minimal ingredients or consider making your own nut milk at home.
- Use Heavy Cream Sparingly: Heavy cream and half-and-half contain lower carbs per tablespoon. They can be a good option for coffee if dairy is not an issue.
Conclusion
Unsweetened plant-based milks, especially macadamia, almond, and hemp, are the top choices for milk with the lowest carbs. Unsweetened macadamia milk comes in at less than 1 gram per cup. Always choose unsweetened varieties and carefully read the nutrition label before buying. These substitutions can help maintain your low-carb goals.
