  • Drinking Water - 8 or 12 glasses?

    Dear Mark,

    I was passing time in the waiting room of the hospital reading a pamphlet. It suggested a 3-liter daily intake of water. Each cup of water is 250ml. 4 cups per liter. That's a total of 12 cups. Already 8 cups per day keeps me going to the WC quite often.

    Reading you CW vs PB comparison pamphlet I did not see a mention of water drinking recommendation. Is there any?

    My recommendation is to take your weight in pounds, divide by two and change the units from pounds to ounces. That is how many ounces of water you should drink every day. Divide that by eight to make it be 'glasses'.

    Mind you, this is my thing. I don't think it is dogma for anyone.

      IMHO, drink until your urine is light and clear. That's the best test. If your urine is dark, you're dehydrated (except the morning - it's typical for your urine to be darker in the morning). But, during the day if your urine remains dark, you need to step up your fluid intake.

        I've long railed against the CW of a certain number of glasses of water, and against the concept that "by the time you're thirsty, you're dehydrated". What sense would THAT have made in a primal times? Surely we evolved so that our thirst was a reliable *early* indicator that we should drink something? Rather than heading out across the savanna, bypassing the drinking hole, despite being already dangerously dehydrated without our body letting us know?

        And where the heck was Grok getting 12 glasses of water spread throughout the day?

        Drink to thirst, but drink good stuff....water, tea, not juice. Mark refers in the PB book to the idea that we get far more fluid from food than we realize too. So I think it's another thing NOT to count, NOT to stress about.

          Drink if you're thirsty. Your thirst is a good indicator of your fluid balance. If a pint of cold water sounds appealing, chug it. Otherwise, no. There is no research to suggest anything else. If you drink a lot more water than your body can make use of, you are just overworking your kidneys to no purpose.
          And don't drink a ton of water with meals.
          If you are new to the PB - please ignore ALL of this stuff, until you've read the book, or at least http://www.marksdailyapple.com/primal-blueprint-101/ and this (personal fave): http://www.archevore.com/get-started/

            there really is no recommendation for water consumption. i have days where i'm drinking a couple of gallons, and days when i might not even drink a liter. mark makes mention of this at the end of his book, when he describes his food intake over a period of three or four days, and there is very little water (save one day when he drinks as much as two regular bottles because he needs to keep his throat lubed since he's on a radio show).

            you don't 'need' to drink nearly as much as CW suggest for two reasons: 1. you get plenty of water from food, and 2. CW suggests 8-12 glasses because it is so heavily based in grains.
            that said, there is no upper limit on how much water you can drink either (except for drowning yourself or washing away all nutrients). if you're thirsty, drink. if you like drinking water, drink. but don't fret over whether or not you're getting enough--chances are you get plenty without even knowing it.

              There are just too many variables to specify any number of glasses per day. Watch your urine color carefully. It should be a very light yellow color. If it is a darker yellow, then drink more water. VERY SIMPLE, and works for everyone's metabolism, and in all temperature ranges..

                  A caveat to the clear urine thing - if you're consuming a lot of diuretics such as alcohol, coffee, cranberry, etc your whizz could still be clear because it's flushing out of your system, not an indicator of adequate hydration.

                    The latest research as far as I recall showed that caffeine is only a diuretic if you don't usually consume it or consume an uncharacteristically large quantity of it one day. If you consume the same amount every day, your body adjusts and holds on to the right amount of fluid rather than peeing it out.

                      Mark did do a post on water consumption. I don't feel like finding it, but it's there. The gist was to drink when you're thirsty. Simple as that.

                        I have to say my urine is always rather dark. However if I have a lemon juice and hot water in the morning, I find my urine is much lighter for the rest of the day and I wouldnt say my water intake has increased any. I drink tea mostly and I think the dark urine is just toxins coming out.... frankly I have no idea if that is the case, but its what I like to think... so perhaps light urine means there arent any toxins to come out... hmmm If I'm ever anywhere tropical for a holiday I have to admit my urine is always lighter... more sweating (more toxins coming out??) and probably more water going in....

                        I do have a reminder set on my outlook to get a glass of water at 10am and at 3pm each day. Sometimes I even drink it!

                          Again, this is pure nonsense. Think about it. Take Griff as an example. He used to weigh more than 300lbs - are you saying he should have been drinking 150oz of water per day...?! That's about 4.5l! A glass is 250ml - that's 18 glasses per day. You DO NOT need that much water. In fact, drinking more than your body asks for is gonna do you harm in the long run.

                          Mark even covers this in his blog: - http://www.marksdailyapple.com/8-gla...f-water-a-day/ I thought you routinely searched the blog, Periquin? This is why I'm slightly bemused to see such a CW answer from you...

                            Actually, no, this is more CW nonsense. Mark has covered this in his blog. You urine should NOT be 'light and clear' - clear (and by that I assume you mean until it looks as though you're peeing water) is a sign you're overtaxing your kidneys - NOT a good thing to be doing.

                            There are lots of things which could darken your urine - certain foods (e.g. beetroot, turmeric, spinach (yep, if I eat enough of the stuff my pee is green!) carrots, red cabbage - think of all the coloured veggies you can eat, they can all affect the colour of what comes out t'other end!)

                            There are also things which can make your pee cloudy which don't necessarily indicate dehydration; I find that, not only does my pee stink when I eat asparagus (that's a whole other topic; many people don't notice their pee is stinky, I certainly do - my mother also does, but my father and sister don't) but it goes cloudy. No idea why, but it's a natural thing to do with eating asparagus, I assume.

                            There is a commercial over here (for Strongbow* - I remember now) which carries the slogan 'Obey your thirst' - the same is true of water. It's not necessary to drink if your body isn't telling you it needs it - and it's another CW myth that "if you're thirsty you're already dehydrated". Bollocks!

                            I take a lot of supps, so I get through about 1-1.5l a day (Periquin, if I was to use your reasoning, I... oh wait, I do. But not intentionally - just take so many pills (and I take ALCAR 2x day too and that needs to be diluted with 8oz or it makes you gag (lemon stevia helps, though...))

                            Talking of which, I was due a dose at 7 - it's now 8!

                            Drink when you're thirsty, don't when you're not. Simples! (as that mildly annoying meerkat would say. Brits'll know what I'm on about!)

                            *Strongbow, if you don't get it in the US (I believe the Aussies and Kiwis do - we imported it to Oz as revenge for them inflicting the likes of XXXX and Foster's on us! ) is cheap, nasty, crappy cider which has probably never been within 100 miles of an apple. Ever!)

                              Summer in Japan is brutal, so hot and humid. Sweating buckets just walking at a snails pace. 3-4 litres on some days wouldn't be a joke. Mid winter though its about a litre may be 2, tops. THats just water. Throw in coffee and the odd tea too.
                              Fear of the unknown...They are afraid of new ideas. they are loaded with prejudices, not based upon anything in reality, but based onÖ if something is new, I reject it immediately because itís frightening to me. What they do instead is just stay with the familiar.
