(Mass out might actually be substantially easier if it’s okay to ignore exhaled air, sweat, etc., but I have no idea whether that’s okay; we’re typically talking about quite small changes relative to the time taken.)
When you lose weight, most of it exits through the breath. In the very short term, fluctuations are dominated by the matter visibly entering at one end and departing out the other, but that is noise.

Thanks! That’s a great example of how weird this topic is and how inadequate common sense is to the task of understanding it.
