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 ?

A balloon full of helium has more mass than a balloon without helium, but less weight https://en.m.wikipedia.org/wiki/Mass_versus_weight.
~~Methane weighs more than nitrogen (70% of atmosphere); you lose weight and mass. Molar mass of nitrogen 7; methane 16. ~~

Edited to comment about mass: Except that a) methane is leaving the body and is not necessarily being replaced; the volume is simply taken up by a contracting colon and b) methane may be less dense than air, but it does contain fecal particles as well, which are tiny but still heavier than air.
This guy farts.
But he doesn’t let it weigh him down.
