Regardless of how much weight you have to lose, weighing yourself periodically is important to keep track of your progress. For obese people, recording weight at home can help avoid embarrassment, save regular trips to the doctor's office and maintain privacy. When buying a scale, choose one that works accurately for larger people. Most bathrooms scales top at 300 to 400 lbs. of weight, but they may not be accurate at high numbers, because they're not designed for high numbers. Professional scales, such as those manufactured by Siltec, are a good option.
Set the scale on an even surface. Don't place it on top of carpets or rugs, as this can affect the readings. If you have tiles on the floor, make sure none of the scale's feet are on the grout between the tiles. Check that there is no water on the bathroom floor to avoid damaging the scale.
Place the scale away from the wall so the person has a chance to stand up straight without touching the walls. You can place the scale next to the towel holders, so the person has something to hold on when getting on and off the scale. He should stand without support before the weight is recorded, though, for more accurate readings.
Have the person look straight forward at eye level. If she looks down, trying to see the numbers on the scale, her weight will shift and the readout will be affected.
Wait until the person has gained balance before recording the weight. On electronic scales, the scale will record weight as soon as you step into the scale, so readjusting once you're on it can result in an inaccurate reading. In that case, the person should practice getting on and off the scale in one single movement.
