title: Measurement of composition changes using dual-photon absorptiometry in obese patients undergoing semistarvation.
abstract: The changes in total fat mass (TFM) and lean body mass (LBM) under semistarvation treatment were measured by dual-photon absorptiometry (DPA) in this study. Three females with massive obesity were followed over two periods consuming a very-low-calorie diet (VLCD). Although LBM changes attributed to water shifts related to sodium balance were observed, DPA proved sensitive enough to measure LBM and TFM changes in semistarvation treatment. LBM measured by DPA did not change significantly following 4 weeks of VLCD. However, TFM decreased significantly (70.9 +/0 24.1 kg to 62.4 +/- 21.7 kg) and paralleled body weight.
