At home I usually don't eat until noon, but I force myself to eat breakfast in the woods. There is a point when my body & brain starts demanding food and I never want that happening when stuff starts getting real. Oatmeal with nuts and coconut for fat and a bit of protein powder to round it off, Also add stuff like dried berries or chocolate chips. I also fill in zip-lok baggies of this mix and dump it in the pot once I've boiled water for coffee...which is fairly critical. This while I'm getting my gear set in the dark, takes maybe 5 minutes to slug it down with a coffee chaser and I'm good to go. During the day I can then just chomp on jerkey or other snacks and don't eat again until the day is done.
