What is fullness?

FL_Hiker

I've got a question in regards to fullness. When I eat say a oh yeah one bar which is around 230 calories, 20 something grams of protein versus a can of tuna + crackers which is around the same amount of calories and protein, why do I feel SO much fuller eating the second option? I won't be hungry for 2-3 hours longer than I would have if I just ate the bar. They are around the same amount of calories and protein? Is it a fiber difference? Or a difference in carbs? Does one digest slower? Is it all in my head?
Thanks 😊

Edit: I looked into the fat and carb content and it appears the one bar has much more in both categories vs my 6 ritz crackers + a can of tuna!

Yup, different combos of macros are more satisfying, and this varies between people.

Calories don’t = fullness. Satiety is an individual thing. Some people will be satiated by higher protein/fat/fiber/volume (which doesn’t mean just gorging yourself in pounds of vegetables-after all, a little over 2T of peanut butter has the same calories in the bar or the tuna/cracker combo). Even texture, variety and specific flavor profiles can play a role. I enjoy sweet things a great deal but don’t find them particularly satiating. I would also not be “full” after eating a bar. Other people are. It’s very individual. The magic is in finding what works for you.

Also a one bar is really sweet, which can leave you wanting more mentally, as opposed to a can of tuna....well it speaks for itself lol

I have different degrees of fullness. Protein will keep me full for hours. Higher fibre and high volume will keep me physically full (a bit bloated feeling). Having a donut can keep me mentally full (oh I just had a donut.. I'm satisfied.. and I don't need anything else).

Could be that the tuna and crackers are just a larger volume of food, especially since you’re getting some additional water in the tuna (assuming that’s what it was packed in). The act of eating a larger amount of food, and the feeling of having more food in your stomach, might help you feel fuller.

Fullness is a unique, personalized blend of psychology and biochemistry, with a dash of social history and genetics.

Fullness is an elusive beast. It is rarely seen but sometimes witnessed for a moment. It is thought to be a close relative to Sasquatch.

With the edit, this doesn't make sense. If two options have the same amount of protein but one has more of both carbs and fat, they can't have the same number of calories (unless you're dousing your tuna in alcohol).

I never said they were equal. I said around. They are both in the 200-300 calorie range. Why would I put alcohol in tuna? One is roughly 40-50 cal more, not enough of a difference I would think to make a large impact on satiety.

My can of tuna is telling me 200 calories and 35 grams of protein.

I think you just get more food volume for the same calories with the tuna.
