Why is my bone mass weight so low?

Styku's body composition values are similar to what you would receive from a DEXA device. DEXA estimates dry bone mass.

While the average human skeleton weighs about 10-14 kg, accounting for around 12-15% of total body weight, DEXA (and Styku) estimates dry bone mass without the marrow, water and blood.

The dry weight of the skeleton of most males weighs between 2kg and 4kg. The dry weight of the skeleton of most females weighs between 1.5kg and 2.5 kg.
