Can you have milk on a keto diet? Yes, but regular cow’s milk contains too many carbs to fit most keto plans. One cup of whole milk packs 12 grams of carbs, which eats up most of your daily limit. Better options exist that give you the creamy taste without kicking you out of ketosis.
How Many Carbs Are in Different Types of Milk?
Regular milk fails the keto test because of lactose, the natural sugar in dairy. Here’s what you get in one cup:
- Whole milk: 12g carbs
- 2% milk: 12g carbs
- Skim milk: 12g carbs
- Almond milk (unsweetened): 1-2g carbs
- Coconut milk (unsweetened): 1g carbs
- Macadamia milk: 1g carbs
- Heavy cream: 3g carbs per half cup
The fat content changes between milk types, but the carb count stays the same. Skim milk actually works worse for keto than whole milk because you lose the fat without cutting any carbs.
What Milk Can You Drink on Keto?
Unsweetened nut milks and coconut milk work best. These options keep your carbs low while adding creaminess to coffee, smoothies, and recipes.
Almond milk tops the list for most keto dieters. One cup contains only 1-2 grams of carbs and costs around $3-4 AUD at Australian supermarkets. The unsweetened version tastes mild and blends well with everything.
Coconut milk from a carton (not the canned stuff) gives you 1 gram of carbs per cup. The canned version packs more fat, which helps if you need extra calories. A 400ml can runs about $2-3 AUD.
Macadamia milk costs more at $5-6 AUD per litre but delivers a rich, creamy texture. The carb count sits at 1 gram per cup.
Heavy cream works in small amounts. Two tablespoons in your coffee adds less than 1 gram of carbs. A 300ml container costs $3-4 AUD and lasts longer because you use less.

Can You Have a Small Amount of Regular Milk?
You can fit small amounts into your macros if you track carefully. Two tablespoons of whole milk contains 1.5 grams of carbs. This amount works in coffee without breaking your carb budget.
Most people on keto aim for 20-50 grams of carbs per day. A full cup of milk takes up 12 grams, leaving little room for vegetables and other nutrient-dense foods. The math just doesn’t work for regular servings.
What About Lactose-Free Milk?
Lactose-free milk still contains 12 grams of carbs per cup. The manufacturers break down the lactose into simpler sugars, but the total carb count stays the same. This helps people with lactose intolerance but does nothing for keto dieters.
Does the Fat Content in Milk Matter for Keto?
The fat helps but doesn’t fix the carb problem. Whole milk contains more fat than skim milk, which fits keto principles better. But 12 grams of carbs remains 12 grams of carbs regardless of fat content.
Heavy cream flips this equation. It packs mostly fat with minimal carbs, making it the only traditional dairy milk product that truly works for keto.
How Do You Replace Milk in Recipes?
Unsweetened almond milk swaps in at a 1:1 ratio for most recipes. Baking, smoothies, and sauces all work with this simple switch. The taste changes slightly but most people adjust within a few days.
For creamier results, mix half almond milk with half heavy cream. This combination mimics whole milk’s texture while keeping carbs under 2 grams per cup.
Coconut milk from a can works great in curries, soups, and desserts. The thick texture and rich flavour actually improve many recipes.
What Milk Alternatives Should You Avoid?
Sweetened versions of any milk alternative will wreck your macros. Vanilla almond milk, chocolate coconut milk, and other flavoured options contain added sugars that push carbs to 10-20 grams per cup.
Oat milk fails for keto. One cup delivers 16 grams of carbs, even more than regular milk. Rice milk hits 22 grams per cup. Soy milk contains 8-12 grams depending on the brand.
Always check labels. Some brands sneak in sugar, even in products labelled “unsweetened.”
Can You Make Your Own Keto Milk?
Homemade nut milk costs less and tastes better than store-bought versions. Soak one cup of raw almonds overnight, blend with four cups of water, then strain through a cheesecloth. This makes about four cups of almond milk for roughly $2-3 AUD.
The same method works with macadamias, pecans, or hazelnuts. Add a pinch of salt and a few drops of vanilla extract for extra flavour.
FAQ
Will milk kick me out of ketosis?
A full cup of regular milk will likely stop ketosis for most people. The 12 grams of carbs combined with other daily carbs pushes you over the limit.
Can I have milk in my coffee on keto?
Use heavy cream or unsweetened almond milk instead. Two tablespoons of heavy cream adds richness with less than 1 gram of carbs.
Is A2 milk better for keto?
No. A2 milk contains the same 12 grams of carbs as regular milk. The A2 protein may help with digestion but doesn’t change the carb count.
What about goat milk?
Goat milk has 11 grams of carbs per cup, barely better than cow’s milk. It doesn’t work for keto.
Can kids on keto drink regular milk?
Kids need more flexibility with carbs than adults. Talk to a doctor before putting children on strict keto diets. They may handle small amounts of milk better than adults.
How long does homemade nut milk last?
Store it in the fridge for 3-4 days. The lack of preservatives means it spoils faster than commercial versions.
The Bottom Line
Regular milk doesn’t fit keto because of high carb content. Unsweetened almond milk, coconut milk, and heavy cream give you better options that keep you in ketosis. Small amounts of regular milk work if you track your macros carefully, but most people find it easier to switch completely to low-carb alternatives.
