after eating do we feel full based on the volume of the food we eat or the calories we consume?
In: Biology
Volume for sure. I’ve done a lot of experimenting 😬
I think calories will make you feel satisfied longer. I can drink a Diet Coke and feel full, but not for long
Bit of both. Many things contribute to you feeling hunger. Your blood sugar levels, how full your stomach is, and certain hormones can make you feel hungry or full.
Lots of the characteristics of the food you eat matter too. What type of food(carb/protein/fat), fiber content, water content, even the food being hot or cold can make a difference.
There’s a great book called Proteinaholic where a bariatric surgeon talks about this exact topic.
You can get full eating a large portion of something that has almost no calories.
Like lettuce.
Calories don’t get you full , volume does.
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.
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)
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.
