no, fat does not have nerve cells. you can feel weight loss in your pants, but not in your fat.
I can feel when I'm losing weight. It's an overall feeling in the morning before breakfast. No, it's not hunger, it's sort of a vibration.
I think I can feel it - a bit like restless legs only in different areas. Hard to say, though. And it only comes when I lose a whole chunk of weight, like in the last days.
But it could also be my overactive imagination.
Before I lose weight in an area, I often notice it starts to look more lumpy, like the fat is actually breaking down in that spot. Its like a rippled appearance.
Congrats on losing the chin, that was the last straw for me lately for motivating me to change my lifestyle. I really want just one chin.
