| Method | An analysis of carbon-14 levels and a simple birth and death model determined the death rate to be 8.4 ±6.2 % per year. It was determined that there is an approximately constant number of adipocytes over time after adolescence (650 subjects, ages 20-70). Therefore the birth and death rate must be the same, and equal to the turnover rate. |
| Comments | The value is the median +/- the average deviation. This results in the replacement of half of the body's adipocytes in 8.3 years. |
