10 Lowest Calorie Milk Options (Complete List)

I’ve spent over 20 hours researching every type of milk, and below, I’ll give you the ten best low-calorie milk options.

In a Hurry? Here Are The Top Picks

• Unsweetened almond milk is the lowest calorie option (25 calories per 8 ounces). The downside is its low protein content, with only 1 gram.

• If you’re looking for a high-protein option, check out ultra-filtered fat-free cow’s milk, which is 80 calories and 11 grams of protein per 8 ounces.

• Picking low-calorie milk with a higher protein content is ideal for weight loss because it has a more significant satiating effect. In other words, it keeps you full for longer.

10 Low Calorie Milk Products

Almond Milk

Unsweetened Almond Milk

Per 8 Ounce Serving

• Calories: 25
• Protein: 1 g
• Fat: 2 g
• Carbs: 1 g

Sweetened Almond Milk

Per 8 Ounce Serving

• Calories: 60
• Protein: 1 g
• Fat: 2.5 g
• Carbs: 8 g

Almond milk is made by blending almonds and water, then straining the mixture. This strained liquid is called almond milk.

Unsweetened almond milk contains the least amount of calories of any milk alternative and fortified versions remain a good source of calcium (approximately 23% of your recommended daily value in 8 oz.). 

This plant-based milk alternative is also cholesterol and lactose-free. However, it is very low in protein at just one gram (g) per 8 oz. serving.

Almond milk is great if you are looking for a milk substitute for your cereal, smoothies, or coffee, but it doesn’t replace the protein found in cow’s milk.

Cashew Milk

Unsweetened Cashew Milk

Per 8 Ounce Serving

• Calories: 25
• Protein: 1 g
• Fat: 2 g
• Carbs: 1 g

Sweetened Cashew Milk

Per 8 Ounce Serving

• Calories: 60
• Protein: 1g
• Fat: 2.5g
• Carbs: 8g

Cashew milk is made by blending cashews with water and straining the mixture.

Cashew milk is nearly identical to almond milk in every aspect, but it’s less likely to be fortified with vitamins and minerals. 

The other main difference between cashew and almond milk is the taste – cashew milk has a slightly stronger, earthy flavor.

Flax Milk

Per 8 Ounce Serving

• Calories: 50
• Protein: 0 g
• Fat: 2.5 g
• Carbs: 7 g

Flax milk is made by blending flax seeds with water and straining the mixture.

Flax milk is similar to almond and cashew milk, though it has a thicker consistency and is a little higher in carbohydrates.

Flax milk is high in heart-healthy polyunsaturated fats, but like almond and cashew milk, it isn’t a good source of protein.

Macadamia Milk

Per 8 Ounce Serving

• Calories: 70
• Protein: 1 g
• Fat: 4.5 g
• Carbs: 7 g

Macadamia milk is made by soaking macadamia nuts in water for several hours, then blending and straining the mixture.

Like almond and cashew milk, macadamia milk is very low in calories and protein, but it’s higher in fat and slightly lower in carbs. 

Macadamia milk’s fat content and slight vanilla taste make it a good option as a coffee whitener, and fortified versions also provide vitamin B12.

Unsweetened Soymilk

Per 8 Ounce Serving

• Calories: 80
• Protein: 7 g
• Fat: 4 g
• Carbs: 4 g

Soymilk is made by soaking soybeans before grinding them with boiled water. The mixture is then cooked, blended to create an even consistency, and strained to remove remaining solid parts.

Soymilk is a good source of plant-based protein and is often fortified with calcium and vitamins A, D, and B12, making it a close replacement for dairy milk. 

It has a thicker consistency than some other milk alternatives, and some describe it as having a slightly ‘beany’ taste.

Fat-Free Cow’s Milk

Per 8 Ounce Serving

• Calories: 80
• Protein: 8 g
• Fat: 0 g
• Carbs: 12 g

High in protein and low in fat, fat-free milk is a fine choice for someone looking to add protein and carbohydrates to their diet. It’s also a good source of calcium, and fortified with vitamin D.

However, fat-free milk isn’t a feasible option for people with lactose intolerance or milk allergies.. 

Ultra-filtered Fat-Free Cow’s Milk

Per 8 Ounce Serving

• Calories: 80
• Protein: 11 g
• Fat: 0 g
• Carbs: 7 g

Ultra-filtered cow’s milk is made by passing regular cow’s milk through a filter that separates the protein and fat from the water, vitamins, and carbohydrates (including lactose). Then the protein, water, vitamins, and different amounts of fat are mixed together, but the lactose is left out. 

This results in lactose-free milk with more protein and fewer carbs than regular fat-free milk. While it still isn’t safe for people with milk allergies, it won’t cause issues for people with lactose intolerance.

“Milk is a rich source of quality protein that contains all nine essential amino acids. It may help reduce age-related muscle loss and promote muscle repair after exercise.”

–Jillian Kubala, MS, RD

Pea Milk

Per 8 Ounce Serving

• Calories: 90
• Protein: 4.5 g
• Fat: 4.5 g
• Carbs: 6 g

Pea milk is made by grinding yellow split peas into flour, separating the protein from the starch and fiber. This pea protein is then blended with water and strained. 

Like soy milk, pea milk has a higher protein content than most plant-based milk alternatives, with just over half the protein content of fat-free milk.

It is also creamier than most nut milks, making it one of the most cow’s-milk-like substitutes available.

What Is Considered a Low-Calorie Milk?

A low-calorie food contains 25% fewer calories than the regular product. 

Since an 8-ounce (oz.) cup of whole cow’s milk contains 150 calories, a low-calorie milk or milk alternative should contain about 110 calories or less.

Why Do the Calories in Milk Matter?

Drinking milk doesn’t cause weight gain, but beverages aren’t as filling as solid food, so it’s easy to drink extra calories without noticing.  

If you are drinking milk or adding it to coffee, cereal, smoothies, or shakes, switching from high-calorie milk to low-calorie milk can be an easy way to remove calories from your diet. 

For example,  switching from a cup of whole milk to a cup of unsweetened almond milk with your morning cereal will remove 125 calories from your meal, which would add up to fewer 875 calories at the end of the week.
