Sharts and puking excluded from this question, I mean warm gaseous emissions only, do we gain or lose weight?

"Technically, yes, you do weigh less after farting. When you expel gas from your body, you're removing mass, which means your weight decreases. However - and this is a big however - the amount is so incredibly tiny that it's essentially meaningless for weight loss purposes."

    Burping and farting are tiny, but if we're talking gasses and changing weight, the vast majority of the mass you lose from fat when you lose weight actually comes out in your breath.

    OP's concept seemed to be about buoyancy. In the same way that a hot air balloon weighs more when it releases hot gas, so too should a human weigh more when they release hot gas. So the question comes down to, is the decrease of buoyancy force more or less than the weight of the ejected gas molecules?

    First one to record themselves farting so hard the scale changes, wins!

    For weight loss purposes, you actually lose the weight by breathing. O2 in C02 out. You're constantly shedding carbon. Does breath count as warm gaseous emissions?

    Does the warm carbon dioxide and other warm gaseous compounds sink or float?

  • I guess warm breath rises, you can see it in winter when your breath is visible.

    However, co2 is not present as a gas in your body, but bound to hemoglobin, so I think it only becomes a gas again in your lungs. Same as farts only forming "outside" your body in your intestines.
