Frequently Asked Questions

When is the best time to measure weight or body fat?
Daily activities, such as food, exercise, and dehydration can affect measurement results. Oserio recommends measuring weight and body fat in the morning, to minimize variables and receive the most reliable and consistent results.

Ideally, you should conduct measurements in the same environment and time of day, to further reduce variables and receive the most accurate body composition calculations.
Who should not use Body Fat scales?
Oserio body fat scales utilize Bioelectrical Impedance Analysis (BIA) to calculate body composition. BIA should not be used by subjects with the following characteristics:

(1) Electronic medical implants, e.g. cardiac pacemaker
A low level imperceptible electrical current will be sent through the body during measurement, which may damage the implanted device or result in malfunction.

(2) Prosthetics and amputation
BIA measures impedance measured using an electric current sent through the body through electrode contact points. As the current cannot flow through prosthetic limbs, measurement is not possible.

(3) Pregnant Women
BIA equations are created based on statistical analysis of sample populations. If subject's body composition differs significantly from these sample populations, equations derived from "normal" healthy adults will be inherently less accurate in these subjects. Women undergo a wide range of body composition changes during pregnancy, including but not limited to change in fat percentage and body water. Without dedicated algorithms, pregnant women should use results with caution and professional advice.

What's the difference between weight scales and body fat scales?
In addition to measurement of weight, body fat scales also utilize Bioelectrical Impedance Analysis (BIA) to calculate body fat and other body composition, allowing users to better undertand their body's current status.
What's the correct way to use a scale?
Before measurement, your scale should be placed on a solid, flat, non-slippery surface. Uneven or soft surfaces (such as carpet) may result in measurement inaccuracy!
