Methane is lighter than air. Methane is indeed ~16 but nitrogen has atomic number 7, molecular mass ~14, and the molecules are N2, so ~28.
Comment on Does farting make you lighter or heavier ?

A balloon full of helium has more mass than a balloon without helium, but less weight 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.

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.
