I can give you one good reason right now.
Yesterday, I ate paleo all day long. The last meal of the day was at 5:30 p.m., which was baked ham slices, a sweet potato and steamed veggies.
It's 9:00 a.m. on Tuesday and I am just now eating my breakfast, which is eggs, sausage, turkey bacon, onions and green peppers. I'm not necessarily even hungry yet. I just don't want to get suddenly hungry and eat something that I will regret, so I intend to get food in me now.
Very yummy! The news on waking up without being ravenously hungry was too good to pass up posting about.
