In brief: Many methods

There are many methods, with varying accuracy.
Bmi is simply wt/ht(2). A simple method for %fat is impedance, and trainers often use them. Gold standard for %fat is underwater weighing, bodpod, or dexa. Rmr requires a metabolic cart which is used in hospitals and research labs. Many of these are relegated to research labs. It is usually not necessary to know all this to be healthy.
