When you have a sensation – is that a circumstance?

I’m trying to figure out where physical hunger goes in my model. I think it’s a circumstance, right? I have a feeling about the sensation that’s happening? So:

C – Physical hunger
T – Eat
F – Anxious
A – Eat
R – Don’t lose weight

I’d like to find a model to help me with the sensation of hunger in my stomach as I detox off of sugar and flour. I know that my body has it’s own fuel but it’s a very uncomfortable sensation. Could an intentional model be:

C – Sensation of hunger in my stomach
T – My body has enough fuel
F – Uncomfortable (hard to parse out here if the feeling is the response to the uncomfortable sensation of hunger…)
A – Don’t eat
R – Lose weight
