Why display the fat mass in lbs and not the fat rate in % of the total mass?
The fat rate is the relationship between the fat mass and the total weight, expressed as a percentage. It can be useful to compare them among individuals of the same age and same sex, but it is however deceiving to interpret the monitoring of your weight over time. For example, if during a diet you only lose water, your weight is lower and your fat mass remains constant. Result: your fat rate has increased. You have however not gained fatty mass. It is therefore preferable to simply monitor the values of your weight, your fat mass and your lean mass in pounds. The Withings WiFi body scale allows you to compare their evolution graphs and better control the effects of a diet.
