Calories in Milk

About Milk

Milk is one of the most complete natural foods available. A single cup of whole milk contains 149 calories, 8 grams of protein, 12 grams of carbs (from lactose), and 8 grams of fat. Milk varies significantly based on fat content — skim milk has 83 calories per cup, 1% has 102, 2% has 122, and whole has 149.

The protein in milk is divided roughly 80% casein and 20% whey. Casein is slowly digested, making milk an excellent bedtime protein source for overnight muscle recovery. Whey is rapidly absorbed and ideal post-workout. Together they make milk one of the most effective protein sources for muscle building.

Milk is also exceptionally rich in calcium (300mg per cup) and is fortified with vitamin D in most Western countries. The combination of calcium and vitamin D supports bone health, and research consistently shows milk consumption is associated with higher bone mineral density.

For lactose-intolerant individuals, lactose-free milk, or plant-based alternatives like almond, soy, or oat milk are options — though each has different calorie and nutrient profiles. BasedHealth tracks all milk varieties accurately.
