How Does the Index Smart Scale Series Calculate Bone Mass?

Index Smart Scales measure several metrics, including bone mass. Understanding this reading is easier when you know what the scale is actually measuring.

Unlike typical methods that include both bone weight and water within the bone, the Index Smart Scale specifically measures "dry bone mass." This is because the percentage of water in the body is provided as a separate metric.

Dry bone mass is calculated based on your age and lean body mass (your total body mass minus fat). On average, dry bone mass constitutes about 7% of a user's total weight. This value tends to be higher in younger adults and lower in older individuals. Other factors, such as your overall health and activity level, also influence your dry bone mass reading.
