The one myth that won't die: You need 8 cups of water

http://fivethirtyeight.com/features/you-dont-need-8-glasses-of-water-a-day/

Quite simply, there are no known benefits to drinking water beyond quenching thirst and making sure you aren't dehydrated (usually easily monitored by checking the color of your urine). I'm not sure why so many on here insist that drinking 8 cups a day is necessary for health or effective weight loss, when the scientific evidence says otherwise.
Does it help satiate? Perhaps for some, but that puts it in the same category as 'you need to eat several small meals a day' type of thinking. Is it a good alternative to sugary drinks because it is calorie-free? Absolutely, but then we are getting into the whole 'sugar is evil' debate.
In short, drink to avoid dehydration and quench thirst, but no need to force yourself to drink copious amounts of water for spurious health or weight loss benefits. Of course, this does not apply to those with specific medical conditions which require substantial water intake - as always follow your doctor's advice there.

    Yeah, I don't think drinking a lot of something that's zero calorie rather than something that's 150 calories per 12 ounces has to do with sugar being evil.

    I've had about 10 cups of water with Mio already today. That's 1000 calories of Dr Pepper as opposed to 0. I like me some DP and some sugar, but not at that price.

    Water has helped in my weight loss more than anything else. When I'm hungry I ALWAYS drink a cup of water first then reevaluate my hunger cue in 30 minutes.... 9 times out of 10, I'm just thirsty. I will say my 29 weight loss is thanks to water (to aid my calorie deficit) and I wish I would have known about it sooner than listening to dumb articles that said we don't need water.

    I drink water after exercising but other than that I drink mostly tea. I don't have sugar in it, and a mug of tea contains the same amount of fluid as a mug of water, so I don't see how drinking plain water would benefit me over drinking tea.

    If I didn't drink 10-12 cups worth a day at least, I WOULD be dehydrated..... I move, I sweat, I digest and my system depends on that much H2O to function at its best. I'm assuming that the 8 cups is an estimate where most people would sit for getting properly quenched. I also wouldn't consider 8 cups (8 oz each) a "substantial" amount. Thirst is one of the final signals of dehydration along with dizziness and fatigue, you shouldn't let yourself get there ideally. No offense I'm not going to go to the bathroom and observe my urine before assessing if I need a glass of water or not, I'll just drink it anyways.

    For me that's not even taking into account that water would be replacing other drinks that might be higher in calories, though I think for many that yes that plays a huge part in aiding weight loss.

    It is better for weight loss because it is calorie free. It has nothing to do with sugar intake.

    Funny. My doctor orders were keep doing what I am doing because he has taught me nothing for weight loss.

    Need. Probably not. Would drinking 8 hurt? Probably not.

    It's like static stretching. Doesn't NEED to be done, but it doesn't hurt to have it in one's regimen.

    This is not really a myth (or a rule); it is an attainable and logical guideline. More people are dehydrated in the world than water-logged. Consider all the people in the world, not just yourself. If you take diuretics, consume caffeine or other drugs, workout/sweat a lot, have a high sodium diet or regular alcohol intake, live in a hot climate, etc. then it would be wise to also ensure you're appropriately hydrated.

    And you cannot always go by clear urine color; case in point, if you take vitamins.

    I regularly get 8-12 cups of water (including black coffee & unsweetened tea) per day with extreme ease.

    I guess I've been missing all the posts where people are whining about having to drink *so* much water. And as far as my personal experience goes, I easily go through 120oz/day + just by having a sip whenever it strikes me to do so. It's certainly not something I force myself to do.

    There are many studies the support drinking water--especially prior to eating a meal--and conclude that it does aid in weight loss. It's no magic bullet, but as others have said, it certainly doesn't hurt. Eight eight-ounce glasses in a day isn't that much, and I drink much more than that even when I'm not in weight-loss mode.

    It's just a general recommendation, not a rule. Chill out.

    I can easily drink over 140 oz of water per day. I'm just really thirsty all the time! Do I NEED it? I don't know, I just want it.

    There's nothing wrong with being hydrated.

    I don't think OP is saying hydration is bad, just that it doesn't have to come from water. We actually get a lot of what we need just from our food.

    On the bright side, that's the only myth related to diet/fitness.

    haha, exactly. There really isn't a need for a debate on this "issue".

    And then some other studies say water can speed metabolism:

    As far the article you linked to, why take nutrition advice from an economics professor?

    Because the folks over at 538 are experts in statistical analysis, which makes them a great reference for evaluating the meaning of studies. It's not as if they are basing their evaluation on 'common sense' or 'things I've heard' or witchcraft. They are using the scientific method.

    This is pretty much me. I may have some Robinson's low cal squash with water at times, but other than water when I'm working out/out and need a cool drink, I pretty much only drink tea with no sugar. Yummy yummy tea!
