Though even in that case, I’d consider water consumed to be covered under “food”.
The only exceptions I can think of are from gaining mass from things other than what you eat. Like tar buildup from smoking, snorting or injecting various substances, boffing something (I think that’s what it’s called… Up the butt instead of out the butt), things sticking to your skin, absorbing through the skin, or bugs/aliens laying eggs inside you. Maybe getting possessed by a ghost, if ghosts have mass. But I don’t think all of those combined would even come close to a single meal, other than extreme cases.
I was curious and looked into how much mass the average adult loses through breathing, and apparently it’s at least about 69g (at rest, if you are metabolizing fat).
