-:::: In turn, ''M'' is the sum of the reference mass at a given height and excess body mass, ''M''<sub>E</sub> <big>≝</big> ''M''-''M''°(Eq. 2). Excess body mass, ''M''<sub>E</sub>, is due to accumulation of an excess fat mass, ''M''<sub>FE</sub>, accompanied by a gain of excess lean mass, ''M''<sub>LE</sub>, which . Thus Eq. 12 and 2 combined yield the definition for excess body mass,

-:::: Inserting Eq. #4 into Eq. 12,
- <big>'''Eq. #5''':  ''M'' = ''M''° + ''M''<sub>FE</sub> + ''M''<sub>LE</sub></big>
-:::: The fat mass, ''M''<sub>F</sub>, is defined as the sum of the reference fat mass and excess fat mass, ''M''<sub>F</sub> <big>≝</big> ''M''°<sub>F</sub>+''M''<sub>FE, hence
- <big>'''Eq. #6''':  ''M''<sub>FE</sub> <big>≝</big> ''M''<sub>F</sub> - ''M''°<sub>F</sub></big>
-:::: Inserting Eq. #6 into Eq. #5 yields body mass as the sum of the reference mass minus reference fat mass (which is the reference lean mass, ''M''°<sub>L</sub> = ''M''-''M''°<sub>F</sub>), plus the total body fat mass and the excess lean mass,
- <big>'''Eq. #7''':  ''M'' = ''M''° - ''M''°<sub>F</sub> + ''M''<sub>F</sub> + ''M''<sub>LE</sub></big>
-:::: Normalization for ''M''° and considering that the [[body mass excess]] is BME=''M''/''M''°-1,
- <big>'''Eq. #8''':  BME = ''M''<sub>F</sub>/''M''° - ''M''°<sub>F</sub>/''M''° + ''M''<sub>LE</sub>/''M''°</big>
-:::: The excess lean mass normalized for ''M''° is a function of BME,
- <big>'''Eq. #9''':  ''M''<sub>LE</sub>/''M''° = ''f''(BME)</big>
-:::: Inserting Eq. #8 and #9 into Eq. #7.2 yields
- <big>'''Eq. #10''':  BME = ''M''<sub>F</sub>/''M''° - ''M''°<sub>F</sub>/''M''° + ''f''(BME)</big>
-:::: Solving for the measured variable ''M''<sub>F</sub> normalized for ''M''°,
-  <big>'''Eq. #11''':  ''M''<sub>F</sub>/''M''° = BME - ''f''(BME) + ''M''°<sub>F</sub>/''M''°</big>
-:::: which finally shows the equation derived to plot the normalized body fat mass as a function of BME,
-  <big>'''Eq. #12''':  ''M''<sub>F</sub>/''M''° = (1-''f'')·BME + ''M''°<sub>F</sub>/''M''°</big>
-:::: In this plot (Fig. 1), the slope equals (1-''f''), and the intercept is the fat mass normalized for the reference mass at a given height in the HRP.
