Interpretation
This is a theoretical energy estimate. Real body weight change is influenced by water balance, glycogen, hormones, metabolism, and lean tissue changes.
How we calculate
Fat mass is estimated as body weight × body fat %. Stored energy is estimated by multiplying fat mass by either 7,700 kcal/kg or 9,000 kcal/kg, depending on the selected model.
