Day 8/P5 cal down/cal up

I slept in late yesterday and wasn't very hungry so i didn't end up eating everything on the plan.  Then today I was hungry from the get go. I had decided to make salad, steak, and baked pot for Valentine dinner at home tonight....so picked day 9 to use again.  Well the toast and fruit didn't do it for breakfast today and i didn't get home for lunch so tried to eat something reasonable at work...but as i have noted 2 other times if i don't eat enough one day i seem to be too hungry the next.  If i eat about 1000 healthy cal i seem to be ok, but if like yesterday i only eat a bit over 800 i seem to rebound.  I did add jello, apples, and the like for most of my excess today and between yesterday and today I averaged less than 1200 a day. I weighed and measured everything so no hidden extras.  Also no real protein to breakfast...if i had done a couple of eggs for breakfast i might have managed better...so the next time this happens I will hard boil some eggs to take to work and just do that day.  Time to go to sleep and move on to tomorrow.
