First day Induction Adkins style

I like meat, so I am usually fine for a couple of weeks.
I find myself strangely empty, but not exactly hungry. I haven't eaten since around 10:00 this morning, (I do on purpose snacks, and schedule them, as I tend to do better when i feel its only a small amount of time to the next time I eat) and I am planning to have lunch. Its not that I miss being hungry, its just that the state I'm in now feels odd.
I haven't had any caffeine all day, but I am not at all tired. I walked 50 minutes at the mall at 11:00, so shouldn't I feel...
