Good question. If you grab a bottle of mineral water or a can of plain seltzer, you’re still looking at zero calories. The tiny amounts of minerals (like calcium or magnesium) don’t add any energy.
Now, if you add a splash of lemon or lime? That’s a different story. A single squeeze might add maybe one or two calories, but honestly, it’s negligible. We’re talking about a rounding error in your day.
And those flavored sparkling waters? Check the label. If they’re “naturally flavored” with no added sugar, they’re still usually zero calories. Pretty cool, right?
