When you wake up you eat BreakFast.. you are breaking the fast that you went on while you slept. It is totally normal to be hungry when you wake up.
especially when you are not eating the right food before bed.
I think its great your hungry in the morning? I am always starving when I wake up! Its good to eat brekky and be hungry. I try to eat more in the morning than afternoon to use it up during the day.
