What tells you when you're hungry?

So it sounds like most people do feel something in their stomach, hunger pangs or pains and feel empty or light headed. That's the way I feel too.

There are days when I don't feel those things, and in my mind, I am thinking "oh such and such really sounds good right now. I know that's head hunger, because my stomach doesn't feel empty
or I don't notice any particular feeling in my stomach.

What I don't get with my friend is she says she never feels anything different in her stomach. It's
all about not being able to get her mind off food pretty much ever. She is the one I talked about before that eats a bag of oreos a day, "because they go down easy and meat doesn't " I am sure she has an eating disorder because she can't ever deny herself anything even if she knows it's bad for her like eating oreos when she is diabetic. I guess that's just complusive over eating.

I'm glad my cravings for sweets has lessened with the sleeve, but there are days when I can't get my mind off candy or sweets. I hate that!

I don't get physical hunger. If I go with out eating I do get an empty sensation and I noticed that I'm irritable.

I do get wicked head hunger. Stomach doesn't growl but I want to do bad things especially if I had alittle carbs. Most of the times I can ignore it, sometimes I'll snack on a couple of Ice pops or pretzel nuggets to get past it.

I do eat on a regular schedule to make sure I get my protein in. So I'm usually eating or drinking something every hour of the day.
