I'm no expert but it means almost exactly what it says, the rest of the % would be water. You never really want to lose muscle unless you're a muscle head and look ridiculous, lol. You want to lose the fat....I believe 28% is right on the borderline of being ok and overweight...so you could aim to get your body fat % to 20. I would do some research online...
