This study was linked over on the VSG forum, and I thought people here would find it interesting. This is just the abstract, but what it says is that changes to what tastes or smells good are common after RNY surgery, and moreover are good predictors of weight loss success.

ABSTRACT It is apparent from day-to-day practice that patients frequently report changes to their appetite, taste and smell after weight loss surgery. There has been surprisingly little written in the literature on this. The aim of the current study was to assess these parameters in a cohort of patients undergoing Roux-en-Y gastric bypass surgery.
Questionnaires relating to appetite, taste and smell were administered to 188 patients who had undergone Roux-en-Y gastric bypass surgery at our institution during the years 2000-2011.
Responses were received from 103 patients (55 %). Sensory changes in appetite, taste and smell were noted by 97, 73 and 42 % of patients, respectively. Seventy-three percent of patients reported aversion to specific foods after surgery, with meat products the most commonly cited (33 %). Patients who experienced food aversions experienced more postoperative weight loss and reduction in BMI, compared to their counterparts without these features.
This study indicates that subjective changes in appetite, taste and smell are very common after Roux-en-Y gastric bypass. Patients are now routinely counselled about these changes as part of the informed consent process for surgery.

I read something similar (could have been the same study) the other day.

I guess I should be glad of this as I have definitely seen a difference in taste.  Things seem so much sweeter to me.  

So hopefully I will be one of the ones that lose more.  ;)

Well crap... I have found NOTHING that I have an aversion to.  Not ONE THING.  I sure hope that doesn't bode poorly for my success.  LOL  (I'm not worried btw - just messin')

I'm pretty much with you, actually. Aside from not wanting to eat in general, the only thing I can't stand now that I loved before surgery is mushrooms. Something about the texture makes them very unpalatable now. Everything else seems ok, though. I know what you're saying, though!

I have that problem with hamburger now.  Before I really loved it, but now the texture throws me or something. I can eat it, but it is far, far down on my list of preferred meats.

I am not surprised at all. I definitely am less fond of sweet tastes but then again I was never much of a sweet eater preop. Carbs, yes, One thing I have noticed is everyone smells like garlic. It started in the hospital. The nurse smelled like garlic, my husband smelled like garlic. My daughter got a kick out of it because I kept whispering "everyone smells like garlic" when I was under the influence of pain medication. I used to love garlic preop but I don't think it will be one of my favorites now. Haven't really tried it yet though.

Oh wow, this is EXACTLY my experience! Garlic...it's on everyone's breath! Sometimes it's hard for me to kiss the husbeast, depending on what he's had for lunch he positively reeks of it, LOL! I guess it's a good thing that I love garlic.

Yep! I am sure I used to reek of it too because I always cooked with it. I keep telling my husbeast (lol, had to say that just once) he smells like garlic too.

that's funny because as I was having issues with certain meats I made them with garlic and grouchy pouch loved them. I probably put garlic on every meat known to mankind the first 6 mo.

I went to Costco a couple of weeks ago and when I went into the bakery area the smell of the sweets made me nauseous. I had never been turned off by sweets before, it was kinda nice. :)
