Does gas "weigh" more?

I eat a fair amount of lentils and beans because I am a pescetarian However, it has the unpleasant side effect of making me gassy :o Can gas make the number on the scales go up?

For the record, I get protein from a variety of sources, and drink tons of water and herbal tea. But I like beans, lentils, broccoli, etc!

    Nope, and all the fiber should keep you regular, which makes the scales go down.

    Yes, you're probably bloated

    We'll call a noticeable scale difference approximately 1/4 lb - 115g. The molecular weight of methane is 16.04g/mol, so you're looking at about 360 litres in volume.
    I really, really hope it's not due to gas.

    I like your style. B)

    Gas doesn't weigh anything- it's just air.

    Gas has a weight, but it isn't so much that you will notice it on most scales.

    Unless too much fibre blocks you up....

    But if you are bloated that doesn't usually mean just gas, it also means retained water or constipation, which DOES add weight on the scale.

    Agree

    Intestinal gas is typically:

    59 percent nitrogen, 21 percent hydrogen, 9 percent carbon dioxide, 7 percent methane and 4 percent oxygen. It has less O2 than air which would make it heavier but has more methane, which it lighter than air. So, it's probably about the same weight per volume as air. So, no, you're not changing you weight by farting.

    Lol

    But it is pressurized. If it weren't then you wouldn't be able to fart.

    What if the gas is compressed?

    The human body can't compress gas to the extent of noticeably increasing its density. You need something like a steel canister to do that, not soft squashy organic tissue.

    To answer your question, imagine farting into a balloon. Would it weigh any more than the empty balloon did already? No.

    Thank you for that great mental image! I'm obviously still 12.. :laugh:

    I'm sitting at my desk at work desperately trying not to burst out laughing and look like a crazed person

    I'm so with you. Thankfully, I work from home, which means I'm actually laughing out loud like a crazy person. My dog's giving me the side eye, but he's always been the judgemental type, so I've learned to ignore it.

    That's stink-eye. ;)

    This is pretty awesome. I would suggest waiting until you have a big toot, and then go stand on the scale right before you let it out, and then see if the scale changes once you do!

    works for poops.



    um... or so I've heard.

    yeah. that's what I've heard. I've never tried it.
    eta... and CERTAINLY not yesterday, when I lost two pounds.

    I guess that is going to depend on how good the sphincter muscles are - a muscle group which is sadly often neglected by fitness enthusiasts ;)

    But it feels like you do sometimes, amiright?!
