Description/Abstract:
CHANGES IN THE COMPOSITION OF THE WHOLE BODY AND OF SUBCUTANEOUS ADIPOSE TISSUE HAVE BEEN STUDIED DURING WEIGHT REDUCTION IN 2 HUMN SUBJECTS. THE WHOLE BODY LOST TISSUES RANGING IN DENSITY FROM 0.92-0.96 GMS/ML AT BODY TEMPERATURE, CONSISTING OF 55-85 PERCENT FAT. THE ADIPOSE TISSUE FAT CONTENTS FELL DURING WEIGHT LOSS FROM 80-85 PERCENT TO 65-80 PERCENT OF THE WHOLE TISSUE, OR BY ABOUT 50 PERCENT WHEN RELATED TO THE DRY, DE-FATTED RESIDUE. THE DENSITIES OF FAT DEPOTS INCREASED, THEREFORE, AS A RESULT OF THE EXCESS LOSS OF TISSUE FAT. ADIPOSE TISSUE DENSITIES CALCULATED FROM CHEMICAL COMPOSITION AGREED WELL WITH THE VALUES OBTAINED BY DIRECT DETERMINATION. FROM THESE OBSERVATIONS IT IS CONCLUDED THAT WHILE ADIPOSE TISSUES PROBABLY CONTRIBUTED THE GREATEST PORTION OF THE FAT AND BODY WEIGHT LOSS DURING WEIGHT REDUCTION, OTHER SOFT TISSUES ALSO CONTRIBUTE SIGNIFICANTLY TO THE BODY WEIGHT DECREASE BY LOSING NON-FAT COMPONENTS. ADIPOSE TISSUE COMPONENTS ARE NOT LOST UNIFORMLY DURING BODY WEIGHT LOSS IN THE HUMAN, AS HAD BEEN THOUGHT PREVIOUSLY.
