The best way to test the accuracy of your scale would be to weigh an unopened bag of cat food or dog food several times. If you don’t own a cat or dog, just weigh something that has a known weight. If your scale accurately displays the correct weight each time, you’re good to go. If however it does not, I would suggest investing in a new scale.
I have an old digital scale that stretches to new heights in inaccuracy. For example, I step onto the scale and I weigh 233 pounds. I step off and step back on, and I weigh 238.5. I try it again and I weigh 235.5. So, have I lost 3 pounds or gained 4? There’s no way of knowing, so I spend the rest of the day thinking that I gained weight. Losing weight is hard enough without having to worry about the accuracy of the scale.Tomorrow: Part Two
