It’s many things combined, including volume of food, composition of food, but also time of day, your mood, if you are busy, how fast you eat, how the food is served and so on.

There are multiple satiety signals. Some detect the amount of stretch, some detect certain nutrients such as proteins and fats.

You can get very full on a small volume of food if it has a high fat content. But for most people, eating fat alone doesn’t seem to be enough to trigger satiety.

Other hormones that play a role in satiety:
Insulin
Leptin
Ghrelin
Peptide YY

Volume of food. Your stomach has nerves which sense how much it has expanded. This is why if you eat faster you’re more prone to overeating than if you eat more slowly.

Adding to what the others said it is also about the time you spend chewing something, also feeling full usually only starts about 20 to 30 minutes after eating regardless whether one ate a medium amount or a lot. So when wanting to reduce the caloric intake it might be useful to eat one plate of something and before getting seconds because you are still “hungry” to wait a couple minutes. Most of the time then you are full. Or eating slowly so you get to the half hour check point with your first portion

The hormones Ghrelin, and Leptin, play big parts in your body determining whether or not you have the hungry/full sensation.

hm…. eating 1000 calories in chocolate and 1000 calories in potatoes… well… i´d say VOLUME plays a major role.

These answers have been interesting. Normally when I eat dinner no matter what it is and I’m fine. My wife has been making braised short rib like once a month later, and while it tastes amazing, I seem to get far more full that I do when I eat the same amount of other foods, I guess it’s the fats? Too delicious?

Basically you have 3 sensors: weight, volume, and calories density or nutritional value. So, you can feel full on a bag of fries, and you can feel full eating a massive salad. And while the salad is healthier and more packed with nutrients and fills more volume, it has less weight and you’ll digest it faster. So you’ll feel hungry sooner. The fries will fill you up oil-calories wise, but will take longer to digest and therefore make you feel full for longer. There’s a great pictogram out there of illustrated stomachs & how full they get based on different foods. I’m not sure how to link things. Google “calorie density” and find the photo of stomachs [stomach pic](https://images.app.goo.gl/wX7Q7sfGh58Hpb4D8)

I read in a book: they did a study with 2 groups. At an all you can eat buffet, group 1 had no restriction what to eat. Group 2 had to eat a certain protein amount. Turns out group 2 consumed less calories. So I would say we are full when having eaten enough protein.

I have input that is purely anecdotal…

I’m one of the weirdos that jumped on the Soylent train. Love that shit, makes work lunches super easy.

If I mix up, say, a 600 kcal of this goopy nutritional slurry, at the end of it, I don’t fee “full” in the same way I do after, say, a chicken dinner or a trip to McDonald’s.

*however*, I do feel almost completely satiated. The “hunger” has gone away but I don’t feel “full” or bloaty and slow.
