Omron Body Fat Monitor and Scale HBF-400

The Omron Body Fat Monitor and Scale HBF-400 earns praise from reviewers for its consistent readings. Consumers say weight readings are spot-on, but like most body-fat scales, the actual body-fat percentage given by this scale is not always accurate. Most reviewers say they aren't concerned about this, pointing out that changes over time are more important than the actual reading. As long as a scale is consistent, it can be easily used to monitor progress. A similar Omron scale was off by only 2.5 percent when compared to underwater weighing, considered one of the most accurate methods for assessing body fat. The Omron Body Fat scale measures weight in 0.2-pound increments (up to 330 pounds) and body fat in 0.1-percent increments for up to four users. It runs on four AA batteries and has a one-year limited warranty.

People who have owned the Omron Body Fat Monitor and Scale HBF-400 and comparable Tanita models say the Omron scale is less expensive and more consistent. Owners advise reading through the manual prior to using this scale, because it can be confusing to use initially. Users should also note that using a body-fat scale under the same conditions each time improves accuracy; body-fat scales should be used at least three hours after a meal, after you've emptied your bladder and not immediately following exercise. Because hydration affects body-fat readings, they should not be used first thing in the morning. If you don't need more than a simple weight measurement, consider the Omega Ultra Slim Digital Bathroom Scale (*Est. $40), which users say offers consistent and accurate weight measurements.
