This guide compares dairy and plant-based milks by analyzing their calorie counts and nutritional profiles. Find the best low-calorie, healthy milk options to suit your specific dietary needs and preferences.

Key Points

  • Lowest Calories: Unsweetened almond milk generally has the fewest calories, often around 40 per cup.

  • Highest Protein: Skim dairy milk and unsweetened soy milk are the leaders for protein, providing about 8 grams per cup.

  • Heart Health: Oat milk contains beta-glucans for cholesterol management, while hemp milk is rich in omega-3 fatty acids.

  • Allergen-Friendly: Rice milk is typically the least allergenic option, suitable for those with multiple sensitivities.

  • The Healthiest Option is Personal: The best milk depends on your specific nutritional goals, such as managing calories, increasing protein, or avoiding allergens.

Understanding the Healthiest Milk with the Least Calories

When evaluating milk options for weight management or overall health, focusing solely on calories can be misleading. A milk's nutritional profile, including protein, fats, and fortification, is equally important. What is 'healthiest' varies depending on individual dietary needs, such as managing calorie intake, boosting protein, or avoiding allergens. This guide breaks down the top choices, comparing their benefits beyond just a low-calorie count.

Low-Calorie Leaders: Dairy and Plant-Based

When your primary goal is to minimize calories, certain milk options stand out from the rest. The key is to always choose unsweetened varieties, as added sugars can quickly inflate the calorie count.

Unsweetened Almond Milk

Unsweetened almond milk is consistently one of the lowest-calorie milk alternatives available, typically containing around 40 calories per cup. It has a mild, nutty flavor and is an excellent option for calorie control.

  • Pros: Very low in calories and carbohydrates, often fortified with calcium and vitamin E. Naturally free of lactose and soy.
  • Cons: Very low in protein, with only about 1 gram per serving. Not suitable as a primary protein source.

Skim (Fat-Free) Dairy Milk

For those who prefer dairy, skim milk is the lowest-calorie option, providing the same essential nutrients as whole milk but with almost no fat. A cup of skim milk contains approximately 80 calories.

  • Pros: High in protein and calcium, which are vital for satiety and bone health. A nutrient-dense option.
  • Cons: Some people find its texture to be less satisfying due to the lack of fat. Fortification with fat-soluble vitamins (like Vitamin D) is necessary.

Unsweetened Coconut Milk Beverage

This refers to the thin, drinkable coconut milk sold in cartons, not the thick, canned variety. It typically contains around 45-50 calories per cup.

  • Pros: Low in calories and carbs, and a good option for low-carb diets. Provides a unique tropical flavor.
  • Cons: Very low in protein. Still higher in saturated fat than most other low-calorie options.

Unsweetened Cashew Milk

Cashew milk is another low-calorie nut milk, often praised for its creamy texture. Unsweetened versions can have as few as 30 calories per cup.

  • Pros: Very low in calories and rich in creamy flavor.
  • Cons: Like almond milk, it is very low in protein unless fortified.

Factors Beyond Calories: What to Consider

The healthiest choice depends on your overall dietary goals and restrictions. Here's how other milk alternatives compare based on specific needs.

  • Protein Powerhouses: If protein is a priority, unsweetened soy milk and pea protein milk are your best choices. Soy milk offers protein levels comparable to dairy milk, around 8 grams per cup, making it ideal for muscle maintenance and satiety.
  • Heart Health Heroes: Oat milk contains beta-glucans, a type of soluble fiber that can help lower cholesterol. Hemp milk is a good source of heart-healthy omega-3 fatty acids.
  • Allergen-Friendly Picks: For those with common allergies, rice milk is often the least allergenic option, though it's typically high in carbs and low in protein.

Milk Type Calories Protein (g) Fat (g) Carbs (g) Key Feature
Unsweetened Almond Milk ~40 ~1 ~3 ~2 Very low-calorie
Skim Dairy Milk ~80 ~8 ~0.2 ~12 High protein, high calcium
Unsweetened Soy Milk ~80 ~8 ~4 ~4 Plant-based protein source

Unsweetened Oat Milk ~120 ~3 ~5 ~16 Contains heart-healthy fiber
Unsweetened Hemp Milk ~60 ~4 ~5 ~1.3 Good source of omega-3s

Making Your Choice: The Best Milk for Your Diet

Choosing the best low-calorie milk depends on balancing your needs and preferences. If your primary driver is calorie reduction, unsweetened almond milk and skim dairy milk are the clear frontrunners. However, if you need a higher protein content, unsweetened soy milk provides a more balanced nutritional profile with a modest calorie count. Similarly, if heart health is a concern, oat or hemp milk offers specific benefits, even with slightly higher calories. Always check the nutrition label for fortification with essential nutrients like calcium and Vitamin D, as well as for any added sugars. The best choice is the one you will consistently enjoy as part of a healthy, balanced diet.


To ensure you are meeting all your nutritional needs, it is always a good practice to consult with a healthcare provider or registered dietitian. For more information on dietary guidelines, visit the USDA website.

Conclusion: Finding Your Perfect Low-Calorie Milk

No single milk is universally the 'healthiest.' While unsweetened almond milk offers the absolute lowest calorie count, skim dairy milk provides a superior protein-to-calorie ratio, and other milks offer specific benefits like fiber or healthy fats. Your personal dietary priorities—whether it's weight loss, managing blood sugar, or boosting nutrient intake—should guide your selection. By comparing the nutritional profiles and reading labels carefully, you can confidently choose the best low-calorie milk to support your unique health and wellness journey.

Frequently Asked Questions

Unsweetened almond milk and unsweetened cashew milk are generally the lowest-calorie milk options, with some brands having as few as 30-40 calories per cup.

It depends on your goals. Skim milk is higher in protein and calcium, making it more nutrient-dense. Almond milk is much lower in calories and carbs, making it better for strict calorie control.

For weight loss, the best options are those low in calories and sugar. Unsweetened almond milk is excellent for low-calorie diets, while skim milk or soy milk offers a good protein boost to aid satiety.

Always check the nutrition label for 'unsweetened' to avoid added sugars. Also, look for brands that are fortified with calcium and Vitamin D, as these nutrients are not naturally present in all plant milks.

Oat milk is made from oats, which are higher in carbohydrates than nuts. This gives oat milk its creamy texture but also results in a higher calorie and carbohydrate count compared to almond or cashew milk.

The creamy coconut milk beverage sold in cartons is relatively low-calorie but still contains moderate fat, primarily saturated fat. This is different from the much thicker, calorie-dense canned coconut milk used in cooking.

Unsweetened soy milk and pea protein milk offer the highest protein content among plant-based milks, with levels similar to dairy milk.
