kesuki's Journal: soy protein isolate...

i am working out for a 10k walk, and trying to lose weight... and as a part of that i have gone on a diet that includes soy protein isolate and whey protein. i wiki searched it, and it says that soy must be cooked to be edible and i assume processing it involves cooking at some point, but and this may be too much information but i immediately noticed it killed off all the stinky gut bacteria... the brand is EAS from abbott and i am slightly concerned by the immediate death of so much bacteria.
  so is the killing of all that bacteria a healthy thing and i shouldn't worry or is it seriously a bad sign. i need to know because the shakes easily suppress my appetite 2 shakes and 2 meals a day and 1 cereal bar snack and 2 sodas which is all totally about 1640 calories, yet i feel full. before the shakes i would eat about 2000 calories never felt full and my intestinal track had plenty of stinky bacteria.
