As it is now, some really good food items have really low full and fed up values (think autumn delight), while some crappy recipes have insanely long 2h+ values.
Overall, it seems a bit random, if not counterintuitive.

As you said yourself on release, values are probably up for some tweaking still;

Why not make the full and fed up time directly proportional to the amount of biles you would gain (on all bars) if you gluttoned the food item with no invariance penalties? Or to it's added values at 0% purity? Or even, proportional to the actual amount of biles gained in all bars upon consumption?

They wont do this because some food is good in other ways, such as having few reduce modifiers, having restore modifiers, being easier to make, being easier to increase purity, or being great regen food.

From what I've seen, the debuff is proportional to the reduce/restore values. If it reduces effectiveness of a food group with 100% chance rather than like 80% chance, it'll be a little shorter, if it reduces three instead of just two, it'll be a little shorter. If it restores something, it'll be a lot longer. If it gives more humor values, it'll be a little longer. Overall, seems pretty fair to me.

Making the debuff scale with the net gain would make it a non-choice. Everything would be almost as good as everything else as long as you could keep eating more, but other than that for short sessions, you would have the exact same time debuff for the exact same amount of points gained, and that would be boring. I like being penalized for chancing foods with a 10-50 range and not expecting them to all roll 10. It makes you think, consider the odds, weigh different foods against one another etc.

That said, looking forward for some tweaking to gluttony
