The ketogenic diet, characterized by its high fat, moderate protein, and minimal carb content, has gained significant popularity as a short-term tool to promote weight loss and therapeutically treat certain medical conditions like type 2 diabetes and seizure disorders. With the keto diet's macronutrient breakdown typically consisting of 55-60% fat, 30-35% protein, and 5-10% carbs, navigating food choices can be confusing, especially when it comes to dairy-free alternatives like coconut milk. This article delves into the suitability of coconut milk for a keto diet, offering tips on how to incorporate it effectively.
Understanding the Keto Diet
The ketogenic diet is an eating pattern that aims to shift your metabolism from burning sugar as a primary fuel source to utilizing fat for energy. By keeping net carbs low, typically between 20 and 50 grams per day, the body enters a metabolic state called ketosis. During ketosis, the liver converts fat into ketones, which serve as an alternative fuel source, offering a sustained source for both the body and brain. This metabolic shift supports insulin sensitivity and allows your body to tap into stored body fat for fuel. To maintain ketosis, it’s crucial to avoid high-carb foods, especially sugars and refined grains, as these foods raise blood sugar and insulin levels, which blocks fat burning and stimulates fat storage. As Dr. Berg explains, "You never want to do high-fat with high-carb. When you combine fat with sugar, you spike insulin and store fat. You want to burn fat, not store it-that’s what makes keto so effective."
What is Coconut Milk?
Coconut milk is a creamy, white liquid made by blending the grated meat of mature coconuts with water. Unlike coconut water, which is the clear liquid found naturally inside young green coconuts, coconut milk is creamy and rich in texture.
Is Coconut Milk Keto-Friendly?
Yes, coconut milk can be a delicious part of a Healthy Keto® lifestyle-if you choose the right kind. While some coconut milk is loaded with added sugars, full-fat unsweetened coconut milk is low in carbs and provides healthy fats that support fat burning and help you stay in ketosis.
Regular canned or fresh coconut milk is naturally high in fat and low in carbs, making it perfect for a keto diet. The nutritional breakdown of 1 ounce (30 mL) of plain canned or fresh coconut milk is about 7 grams of fat, 1.5 grams of carbs, and 0.5 grams of protein. Roughly 90% of the calories in plain coconut milk come from fat, with the remaining 10% coming from a combination of carbs and protein. Still, the carb content is low enough that you shouldn’t have any problem fitting it into a keto meal plan.

Types of Coconut Milk
Coconut milk is available in several forms, varying in fat content, texture, and carb count. Choosing the right type is essential for staying in ketosis and maximizing its nutritional benefits on a Healthy Keto plan.
Here are four of the most common types of coconut milk:
1. Canned Unsweetened Coconut Milk
Certified organic, non-genetically modified (GMO), unsweetened coconut milk is the most keto-friendly option. It’s thick, creamy, and minimally diluted, giving it the highest fat content and most decadent flavor.
With its impressive fat content and low carb count, unsweetened canned coconut milk is an excellent choice for low-carb curries, soups, and sauces, promoting fat burning and satiety between meals. Native Forest organic unsweetened coconut milk (no guar) is one of the best Healthy Keto® coconut milk options.
2. Canned Light Coconut Milk
Light coconut milk has most of the fat skimmed off, leaving a thinner, more watery consistency. While it’s low in carbs, it lacks the flavor and nutritional benefits that make full-fat versions more satisfying and supportive of ketosis.

3. Carton Coconut Milk
Typically found in the refrigerated section, carton coconut milk is heavily diluted with water and resembles the consistency of regular dairy milk. It’s commonly used in smoothies, shakes, and espresso drinks.
Unsweetened varieties are low in carbs and can fit into a keto diet, but many brands contain added sugars, flavorings, or preservatives. Always check the label to ensure it’s unsweetened and made with minimal ingredients.
4. Coconut Milk Beverages
Coconut milk drinks are often sold in drink cartons, single-serve bottles, or as specialty drinks in cafés and smoothie shops. These products usually contain minimal amounts of natural coconut and often include sweeteners, flavorings, thickeners, and emulsifiers that reduce nutritional quality.
Most of these drinks are too high in carbs and too low in fat to be suitable for a Healthy Keto diet. When purchasing coconut milk drinks, such as coconut-based lattes, teas, or smoothies, always check the ingredients for hidden sugars or additives that can kick you out of ketosis.
Coconut Milk: Benefits on Keto
Coconut milk is a natural, nutrient-dense food that can fit seamlessly into a ketogenic lifestyle. Unlike many processed plant-based milks, pure coconut milk is free from seed oils, added sugars, and artificial ingredients, making it an excellent choice for those focused on metabolic health and low-carb living.

Here are five reasons to add coconut milk to your weekly shopping list!
1. Source of Health-Promoting Fatty Acids
Unsweetened coconut milk contains minimal carbohydrates, helping you stay in ketosis without spiking insulin levels. It’s also rich in health-promoting fatty acids, including medium-chain triglycerides (MCTs).
MCTs are fast-digesting fatty acids that are efficiently converted by the liver into ketones. These fats help promote steady energy, mental clarity, and fat burning, especially when carb intake is low.
Research published in Food Science and Human Wellness highlights that “Lauric acid, a major component of coconut milk, stimulates ketogenesis, therefore contributing to overall brain health, including language, executive functions, global cognition, memory, and attention.”
2. Helps Curb Appetite
With its high fat content, full-fat coconut milk helps promote fullness and satisfaction between meals. This supports natural appetite regulation, especially when paired with intermittent fasting and a low-carb diet.
3. Natural Source of Potassium
Potassium is a vital electrolyte that supports hydration, nerve function, and muscle health. This is particularly vital during the early stages of ketosis, when the body tends to flush out more fluids.
Canned unsweetened coconut milk contains approximately 360 milligrams of potassium per cup, making it an excellent option to replenish electrolyte stores and support steady energy levels while following a low-carb diet.
4. Offers Natural Antioxidant and Antimicrobial Support
The fatty acids and phenolic compounds in coconut milk may help reduce oxidative stress and support gut and immune health.
A study published in Chemical Papers found that coconut milk extracts protected beneficial gut bacteria from oxidative stress, suggesting that coconut milk may help support microbial balance and reduce inflammation in the digestive tract.
Additionally, the lauric acid in coconut milk can be converted into monolaurin, a monoglyceride with potent anti-inflammatory and antimicrobial properties that may help promote normal immune system function and gut health.
5. Versatile and Flavorful
Coconut milk is a versatile ingredient that can be used to add flavor, texture, and fat to many keto-friendly recipes. Add full fat coconut milk to soups, stews, casseroles, and curries for a rich, creamy texture. Or, use it as a base for keto-friendly smoothies, desserts, and creamy salad dressings. You can even make keto chocolate coconut milk by adding a tablespoon of cocoa powder, ½ teaspoon of vanilla extract, a pinch of salt, and stevia to taste in a blender with hot water and shredded coconut. If your blender is small, blend in batches. Use all the coconut in the first batch, then reuse the coconut pulp in the remaining batches. Each new batch will be thinner-this is normal.
How Many Carbs Are in Coconut Milk?
Unsweetened coconut milk is naturally low in carbohydrates and high in healthy fats, making it an excellent choice for a ketogenic diet. One cup (240 ml) of full-fat canned coconut milk contains around six grams of net carbs. However, the carb content varies between brands and types.
Incorporating Coconut Milk into Your Keto Diet
Although regular, full fat, canned coconut milk is great for a keto diet, other varieties may not be as suitable. For instance, sweetened versions may contain enough carbs to push you over your daily limit. Therefore, check the nutrition label to ensure you’re not buying a sweetened type.
Unsweetened, reduced fat options, such as light canned or carton varieties, likely won’t push you over your carb limit, although they won’t do much to help you reach your daily fat target either. Thus, if you’re going to include coconut milk in your keto diet, it may make the most sense to use an unsweetened, full fat version. You should avoid sweetened coconut milk on a keto diet. Reduced fat options aren’t as helpful as full fat ones when it comes to reaching your fat targets.
Keto-Friendly Milk Alternatives
Following a ketogenic diet requires careful consideration of every ingredient, including everyday staples like milk. Traditional dairy milk, while nutritious, can quickly consume your daily carb allowance on a keto diet. Fortunately, there are numerous low-carb milk alternatives that can help you maintain ketosis while enjoying your favorite beverages and recipes.
Understanding which milk alternatives are truly keto-friendly and how to use them effectively can make a significant difference in your ketogenic journey.
Several plant-based and dairy options can serve as excellent substitutes for regular milk while keeping you in ketosis:
Unsweetened Almond Milk
Almond milk stands out as one of the most popular keto-friendly options, containing less than 1 gram of carbs per cup. It's versatile, widely available, and works well in both cooking and baking applications. The mild, nutty flavor complements most recipes without overpowering other ingredients.
Macadamia Nut Milk
This premium option provides a creamy texture and subtle, buttery flavor. With approximately 1 gram of net carbs per cup, it's an excellent choice for those seeking a luxury milk alternative that's still keto-compliant.
Heavy Cream
While not technically a milk alternative, heavy cream is a valuable keto-friendly option. It contains minimal carbs (about 0.4 grams per tablespoon) and high fat content, making it perfect for adding richness to coffee or creating keto-friendly sauces.
Nutritional Considerations for Keto Milk Alternatives
When selecting a keto milk alternative, consider these key factors:
- Carb Content: Always choose unsweetened varieties to minimize carb intake. Check labels carefully, as some brands may add hidden carbs through thickeners or stabilizers.
- Fat Content: Higher fat content can help you meet your daily keto macros. Coconut milk and heavy cream excel in this aspect, while almond and macadamia milk typically contain less fat.
- Additives: Look for products with minimal ingredients. Some common additives like carrageenan or guar gum are keto-friendly but may cause digestive issues for sensitive individuals. Guar gum is a thickening agent derived from guar beans and is keto-friendly.
Using Keto Milk Alternatives in Recipes
Most keto milk alternatives can be substituted 1:1 for regular milk in recipes. However, the fat content and consistency may affect the final result. For best outcomes:
- Use heavy cream when maximum richness is desired
- Choose coconut milk for curry dishes and tropical flavors
- Opt for almond milk in lighter recipes and beverages
- Select macadamia milk for coffee and tea
Common Misconceptions and Clarifications
- Coconut Water vs. Coconut Milk: Coconut water is a translucent, naturally sweet liquid found inside young coconuts. Coconut milk is a thick, creamy, opaque liquid made from the meat of the coconut. Coconut water is a significant source of electrolytes, particularly potassium, the sugar content is too high for most keto plans.
- Starbucks Coconut Milk: Starbucks’ coconut milk contains added sugar and is not keto-friendly.
- Light Coconut Milk: Light coconut milk has much of the fat removed, resulting in a thinner texture and milder flavor.
- Homemade Coconut Milk: Homemade coconut milk can be stored in an airtight container in the refrigerator for up to four days.
