I tried the New Life himulayan Gochi Juice and I found that although it did work, I'm not sure that drinking water before every meal would have the same effect.  To be fair, I only tried 2 bottles of Go Chi.  My friend and I split a case.  I lost weight while I was on it, but the weight came right back when I stopped drinking it before every meal.  It's also very expensive, which is why a friend and I split a case.
