There are a few concerns that will have to be approached before that dynamic can be addressed, I'm assuming. One big one is the presence of economies, and individual wellbeing, all while being measured to scale.
Hey, wait, actually...
I understand that reconciling fort mode and adventure mode having different time scales is a current ongoing project that is being considered tentatively. However, I just noticed that there might be an issue with it, particularly concerning the Economy update on the menu some few years for now. Do you happen to have any ideas on how to short term or long term approach an issue that will likely happen: that adventure mode food consumption would be much more rapid than dwarf/legend mode?
With an economy update, the cost of things like food would have much more significant implications on survival, populations, and the like, and it might force a rough and sudden transition in how adventure mode approaches foodstuffs and similar manners of consumption that don't make the 1:1 translation between modes.
One short term solution I can think of when the times come is for adventure mode to use smaller portions, so that an adventurer can eat at least one meal a day while fort mode dwarves can eat their two-months worth of foodstuffs in one sitting, as happens in dwarf mode currently.
