Is it true that muscle weight more than fat?? that's what i've been told at the gym. I guess they were trying to cheer me up since i havent't lost any weight in like 2 weeks!!! I am dieting and working out bodypump 3 times a week plus Pilates twice and Zumba twice a week. I am a waitress and an office assistante!! I move and don't eat a lot but i feel discouraged since the weight loss is not happening. By the way i did lose 15lbs last last month i wana say when i started.

    People here get mad if you say that, so you must describe in detail that for equal volume samples, muscle will weigh more than fat due to the higher density of lean mass.

    it's incredibly difficult to gain muscle. and for newbie gains it's probably like 2 pounds of muscle over the course of a few months.

    so odds are, you're mainly retaining water which is showing up on the scale.

    are you keeping track of how your clothes fir and your measurements? that will give you more of an idea of how well you are doing

    Muscle doesn't "weigh less" than fat. For it's volume, it simply takes up less room than the equivalent weight in fat. Think of it this way - 5 pounds of muscle takes up about the same volume as 3 tangerines, and 5 pounds of fat takes up about the same volume as 3 good-sized grapefruits. Or think of a pound of fat taking up the same amount of room as a pound of butter.

    Yes, muscle weighs more than fat by volume. What this means is that if you weigh 150 and have mostly fat, you're going to be wearing say a size 10. But if you weigh 150 and it's a lot of muscle, you'll wear a size 6. (Yes these numbers are made up).

    1 pound of fat takes up more space than 1 pound of muscle. That's why you should measure inches rather than weigh yourself. Just because you're not seeing the numbers drop on the scale doesn't mean you're not getting healthier and leaner.

    And feathers don't weigh less than bricks...

    lbs, oz etc... are all standardized units of measure. Everything weighs the same if they weigh the same.... ;)

    Yes, it is heavier but you're not putting on any muscle if you're not doing actual strength training - and even then it's very hard to do. You're either overeating, underexercising, or you just have some temporary water retention. If you don't lose weight for a month then maybe rexamine what you're doing.

    jesus don;'t tell her to eat less and exercise more! with the minimal information she has provided, there's no telling what is going on. generally, bodypump classes are good for an overall warmup for strength training, but the weights are way too light and form is not emphasized. if your gym has weights, drop the zumba and bodypump and get on a beginning strength training like "starting strength" or "new rules of lifting for women." and get a nutritional plan...you cant lift and diet seriously. you need to feed your body when you ask it to work, but its up to you to get the right things going in. tons of resources available, depending on whether you like to read studies (alan aragon), what your goals are (fat loss or muscle building) or are just interested in how your body does what it does day after day (leangains.com or marksdailyapple.com). those are just a few protocols and there are many more. you will have to experiment and find which one works for you.

    a pound of muscle = a pound of fat

    a square inch of muscle > a square inch of fat

    One CUBIC foot of muscle weighs more than one CUBIC foot of fat.

    Nobody here said that 1 pound of muscle weighs more than 1 pound of fat.

    Saying that muscle weighs more than fat is correct. Everyone here knows that this implies that a given volume of muscle is heavier than the same given volume of fat.

    Also, volume is measured in cubic inches, not square inches.

    nope
    a square inch of muscle weights more than a square inch of fat. but both would be the same size.
    lol

    i get what you're saying it, but you worded it in the wrong way.

    If you lost 15 pounds to start out with.....perhaps you've just hit a plateau? Change up your exercise routines...."confuse the muscles"!

    Also, make sure you're eating nutritional foods, not just LESS of the BAD. :-)

    REMEMBER: 80% IS NUTRITION AND 20% IS EXERCISE

Or think of a pound of fat taking up the same amount of room as a pound of butter.

    Using this logic, nothing weighs more than anything else. Cars weigh the same as trucks, laptops weigh the same as full grown men, fresh picked cotton weighs the same as the space shuttle. We may need an infinite amount of space for the volume, but by George, if we have it, we'll make everything weigh the same.

    Please end this thread.

    D=M/V or M=DV. If comparing an equal M...say 5 lbs...then you could use DM(muscle)=DM(fat). Since it is known that D(muscle) > D(fat) then for the formula to be true M(muscle) must be proportionally less than M(fat) or M(muscle) = DM(fat) / D(muscle).

    I concur the thread needs to go.

    Is now the appropriate time to bring up the topic of boats?

    Or floating flat on your back vs floating in various other positions?

    Or of crumpled balls of aluminum foil?

    What about cheaks, spelt and hardy?

    :wink:


    ETA: And if the MFP forum mods would stop deleting these otherwise benign threads, we could point new OP to the old thread and it would potentially end there...but I get the impression that MFP opposes this solution *for some reason*... :huh:
