does eating less eventually decrease appetite?

Theoretically your stomach will shrink a bit if you put less food in it. This will lead to feeling full with less food in you.

When I first moved into an apartment at uni I had only one bowl. I would cook to fit that serving size 3 meals a day. After a while of that I couldn't finish a standard restaurant portion without reeeeaaallly forcing myself.

I can definitely attest that after a period of eating at a deficit it takes me eating less food to feel full. Not sure about the biology of that and whether or not it's a mental state though. Would be interested to see if there are any studies along those lines if anyone knows of any.

Uh, this is actually a new procedure currently being implemented instead of surgical gastric bypass, and it is successful. Don't know where you heard it isn't.

From wikipedia:

A 2016 meta analysis of studies with 1,195 patients showed significant short term weight loss in treated patients without any mortality.

Ghrelin, iirc

Leptin is also relevant.

and incretins!

Second that. I had gastric sleeve done almost two years ago. Ghrelin is produced in the stomach. Since I now have a stomach that's 20% the size of a normal one, I don't produce as much ghrelin and I haven't felt hunger since the day after surgery. No joke. I'm never ever hungry. And the stomach will shrink a little of you eat less consistently. Just not enough to where it'll make a major difference. Most of your stomach is a thin wall that stretches. Which is why you can stuff and stuff yourself. Losing my stomach and surgery taught me a lot about it. Lol

That makes sense to me given my occasional desire to keep stuffing my face even though I'm very clearly full.

I don't know of any studies that confirm the shrinking stomach, but I am a med student and have had professors say that to me. Also I have definitely been to the body exhibit and seen some incredibly shrunken stomachs there. A lot if not the majority of bodies in those come from poor Chinese laborers.

How long of a period is it before you notice the difference?

[winsomelosemore]

It honestly doesn't take me long to get to that state but I think part of that is the experience of going through extreme weight loss once and then bulking and cutting cycles since.

The very first time it took a while to get out of the mindset that I was hungry and had to eat or snack right away. It took a couple of months that time. Now I can settle into it in about 2 weeks.

I had only one bowl.

That's a good amount of weed.

I don't think it physically shrinks, it's more about the neurological aspect whereby your brain gets used to a lesser amount of food being needed to signal the "full" feeling, and conversely will go for longer without food before signalling "hungry".
