title: A short-duration restrictive diet reduces visceral adiposity in the morbidly obese surgical patient.
abstract: BACKGROUND
  This study aims to determine if visceral obesity can be reduced after a brief preoperative diet in obese patients.
  
  
  METHODS
  Forty morbidly obese patients were placed on a 1,000 kCal per day diet for 14 days before bariatric surgery. Patients had weight measurements and an abdominal ultrasound performed on days 1 and 14. The ultrasound measured visceral obesity using the distance between the abdominal muscle and the aorta, the fat thickness of the perinephric space, and the distance between the abdominal muscle and splenic vein. Mesenteric fat burden was calculated and compared.
  
  
  RESULTS
  Thirty-eight patients (95%) lost weight on the diet, with a mean loss of 5.2 lbs. Twenty-five patients (63%) had a reduction in mesenteric fat. The average visceral obesity lost was 7.76 cm3or 3% of the visceral adiposity of the average obese patient (250 cm3).
  
  
  CONCLUSIONS
  A short preoperative calorie restricting diet is well tolerated and results in a reduction in visceral obesity.
