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 ?

At room temperature methane is lighter than the atmosphere on Earth’s surface, not heavier.
However, pressurized in your body it may he heavier. I see no studies measuring this.
