Discussion Overview

The discussion revolves around the question of whether eating smaller meals can lead to a reduction in stomach size. Participants explore various perspectives on the biological implications, personal experiences, and potential mechanisms involved in this phenomenon.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that if the stomach can expand with larger meals, it may also shrink with smaller portions.
  • One participant shares personal experience indicating that after a few days of eating smaller meals, they felt full from smaller portions.
  • Another participant argues that permanent stomach shrinkage is likely only achievable through surgery, noting that the stomach naturally adjusts in size based on food intake.
  • A participant expresses uncertainty about the biological basis but posits that eating less might create a perception of a smaller stomach due to changes in eating patterns.
  • One participant speculates that the flexibility of the stomach allows it to expand as needed, comparing it to a nylon mesh bag that can be crushed and then filled again.
  • Another participant references ghrelin levels and suggests that a smaller stomach might reduce hunger over time, drawing a connection to bariatric surgery.
  • A participant introduces the idea that the stomach's expansion during eating could trigger feedback mechanisms that might be influenced by meal size, though they express uncertainty about this claim.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether smaller meals can permanently shrink the stomach, with multiple competing views and uncertainties expressed throughout the discussion.

Contextual Notes

Some claims depend on biological mechanisms that are not fully explored or agreed upon, and there are references to external articles that may provide additional context but do not resolve the discussion.

Can you really shrink your stomach by eating smaller meals? Just something I've often heard.

Well I suppose if it can be expanded by eating very hearty meals, like the competitive eaters do, it makes sense to me at least that it can shrink by eating smaller portions.
 
I am not sure what is a biological background, but I know from my own experience that after a few days of eating small meals even small meal can make you feel full.

I'm pretty sure that the only way to shrink your stomach in the way your talking about is through surgery.

Your stomach naturally shrinks and expands depending on various factors but I'm pretty sure if you eat small meals or you don't eat at all your stomach will shrink permanently.
What does happen though is it effects your dieting patterns which may make you 'think' your stomach has shrunk because you were only able to eat a lower amount of food.


I'll look more into it though it's a good question.
 
I am fairly sure (though have no proof) that eating less does indeed shrink your stomach.

But I wish to ask: to what end? It's not like a smaller stomach will cause you to lose weight, if that's where you're goin'.

The stomach is an extremely flexible organ and will simply expand as needed. Think about filling a nylon mesh bag. Empty it and crush it up, it will re-open quite small, but that doesn't mean you'll have any trouble stuffing it full of books. It's not like the resilience of the mesh is strong enough to resist putting a book in it.
 
well, if ghrelin is really reduced by bariatric surgery, it suggests that allowing your stomach to 'reset' at a smaller size may reduce hunger in the long run by allowing you to reach satiation sooner, at a smaller meal size.

The expansion of the stomach during eating could trigger a pathway that gives feedback about the amount of extension. Eating less could sensitize the pathway, whereby a smaller extension would cause a higher response (a common biological feedback mechanism). I don't know if this is true, but it is something that could be looked into.

Here an article about the mechanosensitive cells in the stomach: http://www.pnas.org/content/102/41/14913.full
