I use Kahunas as my app of choice just wondering if anyone. Knows how to make meal templates can’t seem to find it

Hi everyone, I’m an aspiring Coach that is willing to learn. I’ve got a quick question maybe I missed it in the nutrition module but for a rest day I understand that carbs come down and fats go up but by how much? As well how many calories should be dropped from your rest day compared to the training day diet?
