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 ?

That’s not true. A balloon full of helium has more mass and more weight than a balloon without helium. Weight is dependent only on the mass of the balloon+helium and the mass of the planet (Earth).
The balloon full of helium displaces way more air than the balloon without helium since it is inflated. The volume of displaced air of the inflated balloon has more weight than the combined weight of the balloon and helium within, so it floats due to buoyancy from the atmosphere. Its weight is the same regardless of the medium it’s in, but the net forces experienced by it are not.
Is there a measure for the force exerted on the ground for something then? Such that a balloon would be 0
