Are scales that measure body fat accurate?

Nikkiey explains that at WarriorBabe, the stance on body fat scales is clear: the numbers and calculations they produce are not accurate. She shares that one of these scales once told her she was 28% body fat, and she knew too much to believe it. Still, she doesn't say to throw it out. If you step on it consistently while following the right program, the number moving up or down can tell you something, even if it isn't true to your actual body.

On Ep. 104, she adds the bigger point: a regular scale only tells you how heavy you are, not what you're made of. Two women can both weigh 150 pounds, one with more muscle and one with more fat. So when you're lifting and the scale won't budge, it may not be showing the progress you're actually making. It's the tool, not you.

Whatever you use, treat it like weighing yourself. Nikkiey says to measure first thing in the morning, on an empty stomach, after going to the bathroom, and to do it that way every single time. Testing in the afternoon will likely give you a number that doesn't line up with your last reading, which makes the comparison meaningless.
