Understanding Carbs in Non-Dairy Milks
For anyone on a ketogenic diet, the primary goal is to minimize carbohydrate intake to maintain a state of ketosis. This metabolic state, where the body burns fat for energy, is easily disrupted by high-carb foods and drinks. Dairy milk, for instance, contains a natural sugar called lactose, making it unsuitable for keto, with a single cup containing around 12 grams of carbohydrates. Non-dairy milks offer a solution, but not all are created equal. The most critical rule is to always choose the unsweetened variety, as sweetened versions can contain as many carbs as regular cow's milk.
The Best Low-Carb Non-Dairy Milks
For the lowest carb count, several nut-based and seed-based milks stand out as excellent choices. These are typically low in net carbs and high in healthy fats, making them a perfect fit for the keto macro profile.
- Unsweetened Almond Milk: One of the most widely available options, unsweetened almond milk is a keto staple. A standard cup contains approximately 1-2 grams of net carbs. It has a mild, nutty flavor and a thinner consistency, making it versatile for coffee, smoothies, or recipes.
- Unsweetened Macadamia Nut Milk: Often considered the 'gold standard' of keto milks, unsweetened macadamia nut milk is exceptionally low in carbs. Some brands offer a product with as little as 0 to 1 gram of net carbs per cup. It provides a rich, creamy texture and a slightly sweet, buttery flavor that works well in lattes and desserts.
- Unsweetened Hemp Milk: Made from hemp seeds, this alternative is an excellent choice for those with nut allergies and a solid option for keto. A cup of unsweetened hemp milk contains around 1.3 grams of net carbs and is a good source of omega-3 fatty acids.
- Unsweetened Flax Milk: Like hemp milk, unsweetened flax milk is a good source of omega-3s and is relatively new to the market. It typically has around 2 grams of net carbs per cup and a neutral taste that won't overpower other flavors.
Other Keto-Friendly Options
While the milks above offer the lowest carb profiles, other options can be used in moderation, provided they are unsweetened.
- Unsweetened Coconut Milk (Carton): The refrigerated, carton version of coconut milk is a good choice for keto, with a cup containing about 3-4 grams of net carbs. This is different from the canned, high-fat version used for cooking, which is denser in calories and carbs.
- Unsweetened Soy Milk: A good source of protein, unsweetened soy milk has a relatively low carb count of about 1.6 grams per cup. However, some people choose to limit soy intake, so it's a matter of personal preference.
Non-Dairy Milks to Avoid on Keto
Some plant-based milks are naturally high in carbohydrates and should be avoided on a ketogenic diet. These include:
- Oat Milk: Made from oats, this milk is a high-carb option. A single cup of unsweetened oat milk can contain 9 to 17 grams of net carbs, which can quickly disrupt ketosis.
- Rice Milk: Like oat milk, rice milk is derived from a grain and is too high in carbs for a keto diet. One cup contains over 20 grams of net carbs.
- Sweetened Versions: All sweetened non-dairy milks, regardless of the base ingredient, contain added sugars and are not suitable for keto.

Tips for Choosing and Using Keto-Friendly Milk
- Read the Label: The first step is always to check the nutritional information. Confirm that the milk is unsweetened and examine the carb count to ensure it fits within your daily macro limits. Pay attention to hidden ingredients that might increase carb content.
- Mind Your Servings: Even with low-carb options, consuming large quantities can add up. Be mindful of serving sizes, especially if you use it in coffee or smoothies throughout the day.
- Homemade Options: If you want to avoid additives and have complete control over ingredients, you can make your own nut or seed milk at home.
- Consider Additives: Be aware of thickeners and gums often used in commercial non-dairy milks, as they can sometimes cause digestive issues for sensitive individuals.
Conclusion
Navigating the world of non-dairy milks on a keto diet is straightforward if you know what to look for. The golden rule is to always choose unsweetened varieties and prioritize milks derived from nuts and seeds like almond, macadamia, and hemp, which are naturally low in carbohydrates.
