Does anyone else get a case of the 'foggy brain' before hunger pains set it?

As the subject suggests I almost always get a case of brain fog before I feel hungry - just wondering if anyone else gets the same?

My version of the brain fog includes lethargy, trouble thinking clearly and lack of focus and concentration. This has spanned over many years and multiple diets both in calorie surplus or deficit. Eating tends to fix the problem so the obvious answer would be blood sugar? I've had multiple full blood tests over the years and nothing abnormal is flagged.

I keep reading about hunger pains and the like but does anyone else experience this and/or able to shed some light?

Cheers!
