    A direct quote from Captain Obvious!

    Which is why it is best to weigh in the morning, because that gives the excess water time to exit the system.

    Well, in fairness to the editors at Reader's Digest, fluid ounces are a measure of volume, not weight. If you drank 16 ounces of gasoline, it would be less than a pound.

    Yes, it should be obvious. Considering the intended audience of the average Reader's Digest reader, the concept of Conservation of Mass might not be all that obvious.

    They could have completed the circuit by stating that 16 oz of urine (urinating, not drinking, Bear Gryllis) can translate to losing one pound of weight. Maybe some lightbulbs would go off with that added info.

    Many years ago when I was going to Weight Watchers the leader had one of the members drink a 16 oz bottle of water during the meeting and weighed her at the end. Sure enough she was up a pound. Not a surprise to anyone, but the point that she was trying to illustrate was that the scale is not the be-all and end-all and demonstrate how easy it is to fluctuate.

    Except for water, which is the only substance with a specific gravity of 1.

    No, it's still a measure of volume.

    In the specific case of water the measurements give the same result, but I doubt OP was giving Reader's Digest a hard time because of the specific gravity of water.

    Depends on whether you are referring to fluid oz or oz by weight. In the case of water, it is exactly the same unless you are in the UK where a fluid ounce is actually 1.04 ounces by weight (because a UK fluid ounce has more volume than a US fluid ounce).

    Yes, I know why the OP is giving Reader's Digest a hard time.

    Typically fluids are referenced using fluid ounces, that is, by volume rather than weight.

    I know that. The whole point of the RD article and subsequent comments is that, in the case of water (and only water), they are the same digits: 16 fluid =16 weight. I do find their use of the word "about" to be rather funny.

    Right. I don't know that a lot of people know that, which is why I made my original post in this thread. I don't know that it's worth mocking RD too hard on this one because even though 16 fluid ounces of water weighs 16 ounces, that's a specific characteristic of water and the definitions involved. Milk is denser than water, for example, so even before your body had a chance to absorb the calories, 16 ounces of milk would affect your weight differently than 16 ounces of water.

    It didn't say anything about milk.

    I didn't say it did. Maybe not everyone, or everyone who reads RD, knows that a fluid ounce of water weighs the same as a scale ounce of water. Not all liquids work like that.

    Honestly, I didn't know that milk weighs more than water. I DID know water is ounce for ounce on the scale though.

    *Science clearly wasn't my interest in school! I'm much more interested now, but there are so many things I simply didn't know because I was too busy not paying attention*
