So yeah, as the title says. If you fart do you become lighter because you loose mass or does the loss of buoyancy make you heavier ?

Methane is lighter than air, so farting makes you heavier.
But not in any measurable way.
It depends on how pressurized it is. And clearly farts are pressurized.
Unless you are in a vacuum chamber, then it makes you lighter. Also you would be dead.
