Fluctuation in Body Fat Percentage
The percentage of body fat over body weight
The fluctuation in body fat percentage are caused by body fat and body weight.
As the sensors in S1/S2 are super sensitive, the slight differences in standing position will result in the tiny differences in the reading. In fact, the composition of our bodies will be different when we carry out activities like eating, drinking, excreting, walking and exercising.
As a result, the readings might be different throughout the day. However, a discrepancy of less than 2% is considered tolerable between two continuous measurements.
Tips: Measure daily at a fixed time (usually afternoon). Avoid measuring after overeating, strenuous exercising, bathing, or during fever. Pregnant women shall use with caution.
