Going from not hungry to dizzy with no in-between?

This is sort of a weird question but im wondering if anyone else has this issue. In an effort to be more in touch with my hunger and fullness cues im really trying to avoid eating without obvious signs of hunger like stomach growling or that feeling of emptiness you get in you tummh.

Despite this, one moment i will be fine and the next i will be dizzy and lightheaded, like when you haven't eaten in a while and. Im not sure why i don't have gradual hunger signals like other people. I try drink enough water so im not sure what else it could be.i have considered that my hunger cues are so messed up from years of eating for every reason but hunger and they no longer biologically function right.

Any thoughts or similar experiences?
