it always acticate the effect in 80% how do you make it activate at 50% ?, srry if it is explained i didn't understand it, i'm learning english
i tried changing the value of "above" by "0.5" but it still need to get 80% to give the effect, i just tried eating only carrots and changed all the "above" values by 0.5 not only one

Share your config files.

Unfortunately, I cannot reproduce your issue. I copied your configs exactly and they work as you wanted. Getting any diet group above 50% will trigger one of the effects, without needing to get to 80%.
