If you can, buy a machine that measures your body fat percentage as well (bioelectrical impedance) - it’s a more meaningful statistic. If you’re measuring once per month, under consistent hydration and bowel volume, it could be pretty convenient. The alternative, buying callipers with which you’d perform a skinfold test, requires you train yourself in their proper use (perhaps someone could teach you).
