Its not gonna revert not even with mods. They would have to literally screw with the code itself and to do that youd have to dig deep into the food and code out all inner workings with the code itself.

Please try to get used to the new system, it has barely been a day since the update is out. I get that the new system is overwhelming but there are ways with which you can quite easily manage stamina distribution. For instance "Tasty Mead" gives you regen buffs for it and it has a quick cooldown. And better foods, give you better stats.

Of course you need to find the new ingredients but that you had to do before the update just as much.
