From a cultural background of having a cooked breakfast, anything less than 3 feels disappointing to me.
Hard to hit 100g protein a day without meat/fish.
Loosely trying to be 100g protein, 160g carbs, 50g fat as a base at the moment with more carbs on more cardio heavy days.
My horror is grounded in sustainability and ethics, not calories...
Sorry, I know it's not really the place for it, but I was taken aback.
