    Wait...so, a pound of something that weighs a pound, weighs the same as a pound of something else that also weighs a pound?

    What is this witchcraft?

    WITCH! Burn her!

    Not this again. Equal volumes are implied. Sure, sure, we mean density, not weight. But only the most pedantic little smeg head, or an utter moron, would believe that anyone thinks one pound of fat weighs more than one pound of muscle.

    I really do believe that people get their panties in a twist about this solely because they like to feel smarter than other people.

    Ok, I'm a geek so this drives me absolutely bonkers.

    Muscle does not weigh more than fat.

    Now, let me support my argument with a little chemistry lesson.

    Mass is a physical property that typically reflects the quantity of matter within an object.

    Volume is the quantity of 3-dimensional space occupied by a solid, liquid, or gas.

    Muscle is more dense than fat, so the same mass of muscle takes up less volume than the same mass of fat. So, the only way that muscle weighs more than fat is when you are comparing the same volume of muscle to the same volume of fat (for example, 1 liter fat to 1 liter muscle), not by comparing the same mass of muscle to the same mass of fat.

    See the thread below for a picture:

    Thank you for your patience with this geek.

    "Muscle is more dense than fat" is meaningless if you do not specify the temperature and pressure they are both at.

    Why doesn't that make you go bonkers as well???

    1) There is a thing called the search button. This thread gets posted about once a week.

    2) The phrase "muscle weighs more than fat" is referring to density, not mass. It's NOT saying "one pound of muscle is more than a pound of fat," which is obviously incorrect and we don't need you to tell us this. It IS saying, "the amount of muscle you can fit into a square inch is denser and therefore weighs more than the amount of fat you can fit into the same space."

    You should totally use the search button to see how many threads have people who say to use the search button.

    Incorrect.

    1lb of muscle will weigh more than 1lb of fat when the fat is on Earth and the muscle is on Jupiter or Neptune (or the Sun, but it would probably be non-existent at that point), given that the two being compared were weighed on Earth prior to the transportation of the muscle to Jupiter or Neptune (or the fat to Mercury, Venus, Mars, Saturn, Uranus or Pluto - dwarf planet that it is).

    You forgot to define weight as mass * gravitational acceleration.

    Yeah, but "muscle weighs more than fat" is easier to say. You don't have to get all technical. It's born and bred for the average thinker.

    OOOOO interesting thought so which would weigh more if you were on top of Olympus Mons during a Mars winter or at the bottom of the Marianas trench?

    When people say that, they are talking about comparing the same volume. The point they are trying to make is that the scale is not the ultimate indicator of fitness because a muscular fit person and fat person could weigh exactly the same, but the fat person is going to look a lot bigger because a pound of fat takes up a lot more space than a pound of muscle.

    This is SO old. Yeah...we know. When people say it, they are not saying a lb weighs more than a lb. I'm pretty sure people know this. :yawn: Old news.

    Hey OP, after this you should start a Lose vs. Loose thread/rant. It'll be great and you will have so many friends!

    But, when you are comparing 2 variable you should keep all else constant, that way you can determine what it is you are testing for. So if you take equal volumes of fat and muscle, muscle will weigh more. So when people say muscle weighs more than fat, they mean by volume, since volume is implied it does not have to be stated.

    I always thought that was basically implied...I don't know of anyone who actually thinks a Lb of one thing weighs more than a Lb of something else...that would be rather stupid.

    You'd be surprised...and it has been stated at least once on the MFP forum. Not kidding.

    I am not responsible for other people's stupidity.
