title: Effect of Soymilk Consumption on Waist Circumference and Cardiovascular Risks among Overweight and Obese Female Adults.
abstract: BACKGROUND
  Soy milk replacement in the diet might have beneficial effects on waist circumference and cardiovascular risk factors for overweight and obese subjects. Therefore, we are going to determine the effects of soy milk replacements on the waist circumference and cardiovascular risk factors among overweight and obese female adults.
  
  
  METHODS
  In this crossover randomized clinical trail, 24 over weight and obese female adults were on a diet with soy milk or the diet with cow's milk for four weeks. In the diet with soy milk only one glass of soy milk (240 cc) was replaced instead of one glass of cow's milk (240 cc). Measurements were done according to the standard protocol.
  
  
  RESULTS
  WAIST CIRCUMFERENCE REDUCED SIGNIFICANTLY FOLLOWING SOY MILK PERIOD (MEAN PERCENT CHANGE IN SOY MILK PERIOD FOR WAIST CIRCUMFERENCE: -3.79 ± 0.51 vs. -1.78 ± 0.55 %; P = 0.02 in the cow's milk period). Blood pressure, weight, liver enzymes and glycemic control indices did not changed significantly after soy milk period compared to the cow's milk period.
  
  
  CONCLUSIONS
  Among over weight and obese patients, soy milk can play an important role in reducing waist circumference. However, soy milk replacement had no significant effects on weight, glycemic control indices, liver enzymes, fibrinogen and blood pressure in a short term trial.
