Total kcal (and appetite) should scale up to match the expenditure but macro proportions don't necessarily need to change much, e.g. if your rest days are happy on 20~30% carb then stick with that. If the activity is intense/anaerobic/glycolytic (seriously heavy lifting) then maybe trade a few fats for carbs but no human is doing that for 8 hours--even if they wanted to, glycogen can only replenish at a certain rate.
