Weight / Fat loss

2.5 litres of water a day is too much if you ask me, unless you are doing some seriously dehydrating activity. 70% of fluid intake is from food anyway, and you only need 6-8 glasses of water on top of that for normal hydration. What is it with all this Volvic water challenge marketing bollocks? Dangerous is what it is - recipe for osteoporosis if you ask me, flushing nutrients right out of your system...

I've been told to take your weight in lbs, cut that in half, and drink that much in oz per day. More if you're sweating.
