The device (1) for controlling the extent of intra-abdominal fat in the
monitoring of an individual's slimming, comprises one electrical signal generator
(2) connected to at least one first pole (3), associable to the stomach
surface, and a second pole (4), associable to the abdominal wall. The poles
(3,4) are connected to detection means (6) and means (7) for
processing said electrical signals, adapted to provide a signal indicating the
extent of intra-abdominal fat. The control procedure of the entity of the intra-abdominal
fat in the monitoring of an individual's slimming, consists in detecting the impedance
of the abdominal fat tissues, and hence, in calculating the extent of intra-abdominal
fat is obtained.
