HI Mordy,
from 5.00AM until 9.00AM, that's a long time without food - I would be starved by then too. And you are exercising in the morning on top of it. From what I heard, the first meal should be eaten, within an hour of getting up and then every two to four hours. I try to keep to that schedule (on weekends I am out of luck on that one) as close as possible, but it doesn't always work.
