How is body fat percentage measured?

The most common method is bioimpedance (BIA), where a weak electrical current quickly and safely assesses body composition. Conditions such as hydration affect results, so measure under as similar conditions as possible each time. Skinfold mesurements are inexpensive but less accurate and depend on the measurer. DXA is very accurate and shows fat distribution, but it is more expensive and requires specialized equipment. For everyday tracking, BIA is the most practical – it’s used in Puhti’s body composition measurement.
