Does Eating Less Really Make Your Stomach Shrink?

By Marygrace Taylor

If you cut back on your food intake, will your stomach actually get smaller, so you’re satisfied with less food?

Of course, said your mom, as she dutifully stuck to her diet of cottage cheese-filled cantaloupe halves and cabbage soup. And though she might’ve been right about everything else, she was wrong about this one.

We’ve all heard that thing about how cutting back on calories causes your appetite to reset. And how over time, your elastic stomach actually shrinks down, so you fill up on tinier portions.

If it sounds ridiculous, that’s because it kind of is, experts say. Yes, your belly does boast rubber band-like properties that allow it to change size, explains gastroenterologist Nitin Kumar, MD. For instance, the elasticity makes it easier to gorge when presented with a giant meal, to help us avoid starving in times of famine. (Something most modern humans don’t have to worry about. But back in our cave-people days, it was helpful.)

As for the shrinkage? Your stomach is capable of quickly snapping back to normal size after a feast. But it’s not going to continue to get smaller—even if you start eating much, much less, says Kumar.

After all, if eating less was all it took to shrink your stomach, it would follow that normal-weight people have smaller food pouches than people who are overweight or obese. But that’s not the case, according to findings published in the journal Gastroenterology. Regardless of how much we weigh, everyone’s stomach is pretty much the same size.

If you’re still skeptical, consider this: Your body was designed to take in enough calories to keep it running, even during times when food is scarce. So you better believe that it’s not going to shrink your stomach when you feed it less.

In fact, most of us tend to feel hungrier when we slash our caloric intake. “Your body begins to think that you’re starving. So you get multiple physiologic and hormonal responses to try to get you back to your weight,” Kumar says. Your system gets flooded with the hunger hormone ghrelin, making food even harder to resist. At the same time, your body temperature and metabolic rate slow down in an attempt to conserve precious energy.

That’s a long-winded, science-y way of saying this: Drastically cutting your portions not only won’t shrink your stomach—it’ll probably backfire. And if you managed to lose any weight, you’ll likely regain the pounds with interest, Kumar says.

None of this is to say that losing weight is impossible. But in order to do it successfully, you need to cut back on food gradually—so your body doesn’t suddenly freak out and think that it’s never getting food again. That means instead of embarking on a crash diet, try cutting back by just 100 or 200 calories a day, Kumar says. It’s enough to help you lose weight slowly and sustainably, but not so much that your body mistakenly thinks that you’re starving.

One thought on “Does Eating Less Really Make Your Stomach Shrink?”

  1. I can believe that your stomach will not get smaller than it started out as. Although it will seem to shrink, compared to the average stomach, which is constantly over filled these days. But I disagree that you can not maintain eating less on a regular basis. I say this because I have gradually eaten less and felt fine. The thing that happens though is that as long as you maintain, your diet n portion size and do not eat more, you can feel fine eating less. The minute you taste n eat more food, it is extremely hard to stop. In short, if you stick to your diet and avoid all other foods (something hard to do around the average person, who over consumes) it is easy to continue eating and feeling full, on less food. The reason it is hard to do is because for modern day people, it is normal to over consume, and think that we are not eating alot. Most people don’t know the difference between being hungry and when their intestines are emptying out. And then w/all the sugars and other appetite motivating things added to food these days, we are gradually becoming addicted to eating more. Not to mention all the meals that include wheat. Of course we will want to eat more. Have you ever noticed how almost everything, you buy today includes some form of wheat? That’s why we are all obese and unhealthy. We have all been manipulated into becoming addicts of those things that generate a profit.
