What happens to the body when you overeat?

Answered on August 19, 2014

I have a problem with overeating. The last time that I needed to stop doing something related to food, I loaded up on info related to why it's bad for me and I quit eating it (Kurt Harris explained eloquently exactly why fruit should be minimized at the least).

But I can't find much info that goes into the science of what happens inside the body when it gets too much food.

So what happens?

After gorging at a buffet last night my first urge was start moving, which provoked a lot of belching out excess food that I was stuffed with. Followed by some serious digestion and sleep, and I woke up moderately hungry. I do this a couple times a year now, but used to overeat on a regular basis. Day in-day out I ended up as you describe, but now when I do it rarely out of stupidity or politeness gorging is just a temporary discomfort.

That is NOT the definition of overeating. Sorry. Like Goose, there are many people who overeat who do not vomit. And that's an understatement. People put more food than their body is prepared for *all the time.*

Ambi got my idea. Overeating literally means for me to eat more than you can and there is a simple physiological reaction of the body to it - spitting it out :-)

Maybe he's saying if you don't vomit, it wasn't overeating?

Somehow I have been able to overeat most of my life but I have never vomited as a result of overeating. :D

I guess I am most interested in what happens to the digestive system when it gets overloaded. When the stomach is too full, too.

I've never seen any evidence that shows excess glucose causing insulin resistance, but I've seen plenty of evidence that excess fructose does.

There is a physiological limit to what you can eat in a single session. If you eat more, you'd vomit. That is what happens in the body when you overeat.

If you have a healthy, normal metabolism, your body will first go into thermogenesis. You'd also start to fidget more and get an impulse to move more, so as to burn off the excess.

Excess protein will be converted to glucose via gluconeogenesis.

If you're unable to do this, insulin would instruct your muscles, liver, and fat to store whatever nutrients are in your bloodstream in an effort to prevent high blood sugar from poisoning your nerve cells and organs.

Repeated incidents of this, a lack of enough muscle tissue to dispose of the excess glucose, or already full muscles will cause a resistance to insulin signaling, which will in turn cause your pancreas to generate more insulin, in the process damaging your beta-cells. If you work out, especially with HIIT, your muscles' glycogen stores will be depleted and they'll be more willing to accept the excess.

Over time, your fat cells will convert and store more and more nutrients as fat and your waistline will get larger. Your blood pressure will go up, and as visceral fat grows, it will invade and/or crowd organs. Some people sadly will not be able to use fat cells to dispose of nutrients and those will wind up being worse off - they're the skinny diabetics you'll run into.

Different tissues become insulin resistant at different levels. First the muscles stop accepting more glucose, then liver, then fat cells, and eventually your brain (which could lead to Alzheimers disease). If you've gotten to this point, your eyes, nerves, and organs will start to get damaged, especially your kidneys which are now sacrificing themselves to dispose of glucose in your urine. Yup, your urine will now taste sweet, and you've now got full blown type 2 diabetes.

Your doctor will prescribe insulin shots and tell you to eat more whole grains, and you'll get fatter and worse off as your levels of insulin rise. If not, your pancreas will give out and stop producing insulin from all the damaged beta cells and now you've got something similar to type 1 diabetes.

tl;dr - work out, move a lot, don't sit all day, build larger muscles, don't consume too many carbs or way too much protein.

When I overeat: there comes a point when my stomach is stretched uncomfortably full and I get a bit nauseous at the idea of eating more. Within the hour I get a rush of energy, get even more fidgety than usual, and I get very very warm - the skin on my torso in particular gets so hot you can feel heat coming off me when you get near. People remark on it. My fiance says I 'burn' him. If I'm in a warm place, I will get overheated and sweat a lot. I simply can't eat much in the summer for this reason.

This is probably why I've never had a BMI of over 17. YMMV. Some people store extra fuel as fat, I burn it ASAP.

Isn't it to do with leptin signalling being all out of whack? As far as I understand it, through years of poor diet, you can mess up you hormone signalling that lets that brain know you are full, the message literally doesn't get there. Breakdown in communication if you like.

You're referring to bingeing in a single session, right? I'm not smart enough to relate the science of it, but I am inclined to think that what happens to you physiologically after a binge session will vary a bit based on the proportion of macronutrients (i.e. protein, fat, or carbohydrates) you're eating. The big bad wolf being, as it usually is, the insulin rush -- and ultimately insulin resistance.

I have learned from an experience I had tonight at the movies. I ate way too much popcorn and candy, and I woke up with a really bad tummy ache. I eventually threw up. I know that when too much food is thrown into the digestive system, sometimes the stomach can't handle it and will throw some of it up. However, it depends on how much you eat. Sometimes, you just get a little nauseous and have a little bit of acid reflux. I hope you are careful- you don't want to end up like me! :)
