Fair enough. I agree on the fact that it is possible to find a research to claim any assertion today.

These detox water recipes- http://www.fabhow.com/how-to-make-your-own-detox-water.html

claim to help you lose weight. How effective they really are, if taken in isolation during an intermittent fast or with the daily routine?

I had that 30/30 rule when I was right out of surgery, but at some point (I think when I was cleared for soft foods), I was told I could drink right up to the point I ate, and then I had to wait at least *60* minutes to start drinking again.  I still follow that rule...

Research it if you like, but the facts above are as certain as the turning of the earth. 

You posted a link above with some "research" saying that drinking with meals is good for your health. It unequivocally is NOT good for WLSers who hope to lose weight and keep it off.

The choice is yours. I imagine you can find "research" to support anything. Heck, I know of one study that says chocolate cake makes you lose weight. But if you want to lose and keep it off, you won't drink during or after meals.

This is a question that so many bariatric programs answer differently! I have worked in three different clinics and have heard...you guessed it...three different recommendations!! For my patients I am fine with them drinking up until their first bite. Once the first bite has been taken, keep liquids out during the meal time and for 60 minutes afterward - 45 at the very minimum. The other answers are here are spot on! This guideline is to keep food in your stomach pouch longer and keep hunger at bay in between meals to keep away from snacking. Your portion sizes are often smaller too when you avoid fluids with the meal. If you feel like you are really dry or are going to choke, I would encourage you to evaluate the size of bites that you take. Many times (especially meat) dry or choking feelings are too large of bite****ting the top of the stomach pouch. Keep bites the size of a peanut and pause in between ;) And yes...the no fluids with meals or afterwards thing is just for post-ops!!! Non-surgery people are okay to drink with meals because of the pyloric sphincter. 

Sorry for the novel but thanks for letting me join in the conversation! 

Recently I have been experimenting with different drink mixes.  Crystal Light is so sweet/fake and has an aftertaste.  Today, I found this brand and I love it! It is much lighter tasting with no aftertaste.  Thought I would share! They also have lemonade which I bought but have not tried yet.
