Milk, buttermilk, fluid vs Milk
Side-by-side nutrition comparison per serving. See which fits your goals better.
The whole milk vs skim milk debate has been going back and forth for decades, and the pendulum has swung back toward whole milk in recent years. The numbers: whole milk sits at 62 calories with 3.31g fat per 100ml, while skim comes in at just 37 calories and a negligible 0.25g fat. Protein is virtually identical — skim actually edges ahead slightly at 3.57g vs 3.21g because removing the fat concentrates everything else.
Here's the nuance most people miss. If you drink a glass of milk with a meal, the calorie difference is roughly 60 calories per cup — meaningful if you're drinking multiple glasses daily, trivial if it's just a splash in coffee. Whole milk does keep you more satiated thanks to the fat content, which can prevent snacking later. But if you're using milk primarily in protein shakes or oatmeal where you're adding other fat sources anyway, skim saves you calories without any satiety tradeoff. Context matters more than the label.
Pro tip
If you can't stand the watery taste of skim but want to cut calories, try mixing half whole and half skim. You get 80% of the creaminess at roughly 50 cal per 100ml — a solid middle ground.
