Sharts and puking excluded from this question, I mean warm gaseous emissions only, do we gain or lose weight?

Burping and farting are tiny, but if we're talking gasses and changing weight, the vast majority of the mass you lose from fat when you lose weight actually comes out in your breath.

    OP's concept seemed to be about buoyancy. In the same way that a hot air balloon weighs more when it releases hot gas, so too should a human weigh more when they release hot gas. So the question comes down to, is the decrease of buoyancy force more or less than the weight of the ejected gas molecules?
