Hunger is an odd thing. The more you eat, the hungrier you feel , the less you eat, the less hungry you feel, in general.
so for example you have a large meal on Monday evening. On tues morning, you will likely feel very hungry. You have a small to moderate meal Monday evening, you feel not so hungry the next day. In general as I know there are always folks who are outliers.
the longer you go eating small amounts, the less hunger you feel. And the more you ignore hunger, the more it quietens down to a low background noise.
i have a friend who controls what she eats and ignores her hunger. Most of the time I think she doesn’t even recognise it any more. But put a plate of food in front of her and she will want it but strictly limit what she eats. Put it in front of her when she’s had a couple of glasses of wine and she wants it all. She’s clearly starving and you can see it, and the wine reduces her will power, revealing it.
but if she didn’t have the food in front of her, she’d just carry on and not eat.
