1. What You Should Know When Using This Unit

1.1 What is Body Fat Percentage? 

Body fat percentage refers to the amount of body fat 

mass in regards to the total body weight expressed as 

a percentage.
This OMRON BF400 will provide your specific body fat 

percentage and body weight. It is also an excellent tool 

to estimate your body fat percentage and measure 

body weight on a continuous schedule.
Body fat percentage (%) 

                         = {Body fat mass / Body weight} x 100

Body fat reading is affected by the change of 
water content in the body.

A person’s hydration level and blood circulation may have an effect on their body fat 

reading. In the table below are some situations which could affect the reading.

Cause of Fluctuations

Examples of Fluctuation

Water and food intake

1 to 2 hours after breakfast, lunch or dinner

Changes in blood circulation

After taking a bath or shower, immediately 
after exercising, in extreme environments 
(warm or cold), during illness or extreme 
fatigue
