SUMMARY

The discussion centers on the concept of whether eating smaller meals can physically shrink the stomach. Participants agree that while the stomach is flexible and can expand or contract, significant permanent shrinkage is primarily achievable through surgical methods. Eating smaller meals may lead to a psychological perception of reduced stomach size due to changes in dietary habits and hormonal responses, such as ghrelin levels. The biological feedback mechanisms involved in stomach expansion and sensitivity are also highlighted as areas for further exploration.

PREREQUISITES
  • Understanding of stomach physiology and flexibility
  • Knowledge of ghrelin and its role in hunger regulation
  • Familiarity with bariatric surgery and its effects on appetite
  • Basic concepts of biological feedback mechanisms
NEXT STEPS
  • Research the effects of bariatric surgery on ghrelin levels
  • Explore the role of mechanosensitive cells in the stomach
  • Investigate the concept of desensitization in biological systems
  • Learn about dietary patterns and their psychological impacts on hunger
USEFUL FOR

Individuals interested in weight management, healthcare professionals, nutritionists, and anyone exploring the relationship between meal size and appetite regulation.

Can you really shrink your stomach by eating smaller meals? Just something I've often heard.
 
Biology news on Phys.org
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

Here some material about desensitization (adaptation): http://www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=mboc4&part=A2740#A2826
