Fat-free milk. Same protein and calcium as whole milk at roughly half the calories — the entire saving comes from removing the milkfat.

How does skim milk fit your goals?

With 8.3g of protein per 1 cup (245g), skim milk is a workhorse for anyone tracking macros for weight loss or muscle gain. Protein is the most satiating macro and the hardest to over-eat by accident, which is why high-protein foods anchor most successful cutting and recomposition plans. A single serving covers roughly 6% of a 150g daily protein target — the kind of number that adds up quickly when you build meals around it.

Diet-wise, skim milk fits low-carb, high-protein, and vegetarian eating patterns.

Micronutrients worth noting

Beyond the macros, skim milk pulls real weight on calcium (25% DV) per 1 cup (245g) — the kind of micronutrient density that calorie counts alone don't show.
