Hello,
Here I will paste what I said about gluttony in another thread "cant kill beaver".
For low biles I use to eat only 3 foods that gave me 3 gluttony points and thanks to the timer reduction, I would have like a 6 min timer. Before next gluttony session.
As said before :
Froghetti
Garlic mushroom
Garlic rabbit
Autumn delight.
Those 4 food give easily around 40 biles for gluttony, give a 15min timer, with 90% chance to reduce food efficiency (that s why you should stop after 3)
Try to eat only 3 and look at your timer, it should be around 6 min.
Stop your gluttony and you can start again soon.
Basically 3 humors every 6 min is not so bad.

Ps: Dont forget to boil the mushrooms.
After a while one dish will not give you one point anymore, so I was eating 2 dishes to gain 1 point, stop the gluttony and wait for the 30min timer before gaining another point.
I think i did that until humours 90. But maybe you ll get tired of that before.
Then you should consider the longer gluttony sessions.
For that you need to kill some beavers. Gather or plant Devilwort to prepare devil beaver. You can also buy bear and deer meat if you find it at good price (devilbeaver prepared with rabbit, beaver, deer and bear will improve your 4 different biles).
Or you can for example prepare shroom legume salad (requires green cabage and radish) with toadstool, blewit, witch hat and morels.
Those food will add 3hours on the full and fed up timer but have only 15% chance to decrease efficiency of food by 25%.
You can restore game meat with redbellpepper (like in nutcracker suite).
you can restore mushroom with recipe using "any garlic" with garlic braid. Like tamale. But this is maybe a bit more advanced.
