i've heard this debated a lot. in fact, we were talking about it at work this morning. at one point in my life i heard, for the amount of water that you need, take your body weight (pounds) and divide it by 2. that's how many ounces you need a day. when it comes to getting it from food or actually drinking water, im not sure it matters. but obviously you cant get all 64oz of water from eating fruits and veggies.
Yup, I've heard that too: weight/2 = ounces of water per day.

eta: that Snopes link is interesting. I can't help but wonder though if obesity would be less of a problem in the US if we all did drink the recommended 8-10 glasses of water per day. It helps increase your energy level, kick starts your metabolism by flushing your system, and it helps you feel full.
Is that just for someone on average or does that take into account exercise and other things?

I've been seeing it debated a lot recently, too.
I think it depends on how much liquid you're getting from your diet otherwise. If you're drinking juices, tea, eating soup and fresh fruit and veggies you'll be getting water from that as well. If it's 100 degrees out and you're running a marathon you're obviously going to need more than if you're chilling in your house eating oranges.
I didn't realize water has any impact on your memory. At least the debating about water should at least make people think more about its benefits and drink more. I'm definitely planning on drinking 10 glasses per day when I receive my water filter.
don't drown. You probably don't need to drink 80 ounces of water - you get a LOT of water in your food already.

And water doesn't help you feel full. It helps you feel full of water, but doesn't curb hunger. When you're hungry, you need food. Drinking a bunch of water will leave you hungry and water-logged.
Just drink as much as you can, but don't drink it too fast! People do better the more water they drink :] Your body loves it.

I read in some women's magazine that drinking a glass of luke warm water in one gulp (or, at least very fast) causes a sudden expansion in your stomach, that tricks your brain into thinking you've eaten.

I tried it several times, and it really worked! But, I don't do it because it works too well, and I'l liable to look up and realize I never ate my lunch, and it's time to go home.

I save that trick for times I'm very hungry, but there's nothing to eat for a while.
Drinking 2-3 litres of water per day like some people say they do is totally unnecessary unless you're very active. The human body was designed to function on far less than that.

But if you want to bump up the profits of bottled water companies, go ahead

Another little tidbit I read:

Since most of us have grown up with a large beverage at mealtimes, and there's so much water in our food (cereal, applesauce, etc...) that many times, we may FEEL hungry - but we're actually thirsty.

I've started paying attention to this, and I feel there's some truth in it. Esp if I'm craving something liquidy, like cereal or cantalope.

Today, I ate as soon as I got to work. One burrito...still hungry...another burrito...still hungry/realize I may actually be thirsty so I drink a glass of water, and I immediately felt satisfied after that.
Well I wasn't talking about drinking a whole bunch to trick your body. But generally drinking a lot of water is a good thing.
Yeah, I know... I quoted you because of the 'but don't drink it too fast' part.
BTW...as long as we're talking about drinking lots of water...does anyone else have this problem:

When I drink plain WATER, I instantly have to pee, and will pee a few more times during the next hour. But, if I drink some other beverage like juice, soda, kool-aid, lemonade, etc...it doesn't have that same effect.

Why is that? I really don't feel like it could be hydrating me very much, if it's triggering my body to instantly lose an equal amount of water, or more.

That's the only reason I avoid drinking plain water...because I don't want to live in the bathroom!

I've noticed that as well. I used to drink soda frequently, and they say it has the opposite effect that water has:it actually causes dehydration. I'm not sure about the other liquids though.

This is actually incorrect, and drinking water won't make your hunger go away. When you're hungry, your body needs fuel (likely that your glucose levels are low). When you're thirsty, your blood volume is low and your sodium levels are high. Drinking water corrects that. Water does not affect your blood sugar, and therefore won't make that feeling of hunger go away. It'll make your stomach feel like there's something in it, but that doesn't last very long and then you're starving and you stuff your face full of chips.

If you're hungry, EAT. eat carrots or a salad or cottage cheese or cucumber slices with hummus. Something. Drinking water isn't a very good diet tactic.

Probably because many sodas contain caffeine. Drink a caffeine-free diet beverage and you should be fine.
I think that many of us eat when we're not actually hungry, and I would think it could be common to not really recognize the difference between hungry and thirsty. We just know we want something, so we go with food.

That is what many dietitians and nutritionists say. That's why it's good to drink water to see if you are mistaking hunger cues for thirst ones and then wait 15 or 20 minutes. If at that time, you are still feeling hungry, you should eat, as it is true hunger.

I meant getting one's wires crossed in their brain...and BEING THIRSTY triggering sensations of being hungry instead.

Right now I'm eating an apple. Why? I had a big bowl of fried brocoli a few hours ago...but was hungry again a half hour later. Hmmm... I shouldn't be hungry after that...So, I drank some cold water, and a glass of soymilk. Nope...still hungry... So, I'm eating an apple...and seriously eyeing my package of tortillas... Burittos!!!!!!
