erythritol weight gain

Erythritol has around 70% of sweetness, similar to that of sugar. So, it’s obvious for you to think of it as an unhealthy agent for your body, which might increase your body weight and raise your blood sugar levels as well. But, it’s not the case! 

Erythritol weight gain is false! Even though the origin of this sweetener is based on carbohydrates, the human body doesn’t absorb erythritol, which doesn’t contribute to weight gain! 

It consists of sugar alcohols that trigger the sweetening effect. Moreover, they don’t even take part in your regular consumption of carbohydrates. As a result, erythritol as a whole is not responsible for weight gain. 

Let’s dig deeper into what Erythritol is and whether or not it’s good for your body! 

Erythritol: What Is It?

Erythritol is a natural sweetener that is quite popularly preferred as one among the low-calorie foods, bakery goods, and sweets. It consists of carbohydrates, a sugar alcohol which makes this sweetener an alternative to sugar. 

It’s a natural substance that is found in fruits such as pears, grapes, watermelons, and peaches. Some of the specific mushrooms also have traces of erythritol in them. The look of it is also similar to that of table sugar. 

People prefer to use it in a similar way they use sugar. They’re using it commonly today in coffee, tea, and baking. But, there will be some differentiation in the taste as it’s a substitute and not exactly a replica of natural sugar. 

Is Erythritol Considered Safe?

You may have doubts and questions about how bad is erythritol for you. You may also think about why is erythritol bad for you. People have verdicts on erythritol to be unsafe! But, the fact is that erythritol is absolutely safe for humans to consume. 

Erythritol is considered a safe alternative to sugar in all aspects. There have been multiple studies for determining any form of toxicity or adversity on metabolism of humans. Most times, it was tested on animals, and the results have proven erythritol to be safe for consumption by both animals and humans. 

But, there is one drawback that has been reported multiple times by the consumers. And that is digestive issues! And this is because they have a unique chemical structure, and the human body fails to digest them properly. They pass our digestive system unchanged till they reach the colon area. 

It gets fermented in the colon by resident bacteria and produces gas as a byproduct of sugar alcohols. Hence, this hampers your digestive system!

If you’re too frequently consuming erythritol, then the sugar alcohols will trigger digestive upset and bloating issues. But the good news is that the chances of you experiencing digestive issues are very thin. It’s because 90% of the erythritol gets excreted through urine after being absorbed by the bloodstream, even before it reaches your colon. 

Therefore, even with one drawback, which is rare for humans to experience, erythritol has a safe profile for your consumption. 

Erythritol’s Health Benefits

To help you better understand Erythritol, here are a few of its proactive health benefits to count on:

Assists in Weight Loss and Weight Management

Sucrose in sugar adversely affects your body weight and increases it over time. Therefore, most people are advised to stop consuming table sugar in their diet to manage their body weight and control its gain. 

Therefore, most people are switching to artificial sweeteners, as going completely sugarless is pretty much difficult for them. Therefore, erythritol is a perfect alternative for us to replace sugar without missing out on its sweetness effect. 

It will help you manage weight and satisfy your taste buds on your favorite sweet dishes without hesitation. 

Restricts the Tooth Decay Symptoms

Sugar breaks down in your mouth due to the presence of bacteria, which then turns sugar into the form of acid. And this acid will wear your tooth enamel and trigger cavity problems. Erythritol is good for oral health as it restricts the growth of acid-making bacteria in your mouth. 

This inhibition of the microbial growth in your mouth will reduce the amount of acid produced within your gut. Hence, erythritol helps you prevent all forms of tooth plaques and cavities. 

Compared to all other natural or synthetic sweeteners, such as mannitol, sorbitol, and others, erythritol takes the most time to start plaque formation in your mouth, which will happen only when you’re limitlessly consuming it. 


Erythritol consists of anti-diabetic properties, which prevents the increase in serum levels of insulin and glucose within your body. It’s an alternative and healthy option for diabetic patients as 90% of erythritol gets excreted through urination without degrading your body. So, there will be no adverse effects on diabetic patients.

Possible Risks of Erythritol

Even though the side effects are rare with erythritol, there are still chances that you can suffer some mild adversities due to over-consumption or the body’s rejection of the sweetener, which include:

  • Nausea
  • Cramps
  • Bloating
  • Diarrhea
  • Headaches
  • Gastric problem
  • Digestive problems

These aren’t common risks for all consumers of erythritol, but overconsumption might trigger it in some instances. But all of these side effects are curable with a mild dosage of respective medications. 

Can Artificial Sweeteners Make You Gain Weight?

Consuming artificial sweeteners won’t cause weight gain, at least for the short term. Replacing sugar with artificial sweeteners, such as erythritol, will help you manage your weight and be part of a weight loss regime. 

Some general artificial sweeteners used in diet sodas and other beverages with sucralose, Reb-A, aspartame, and other harmful sweetening chemicals will contribute to weight gain. 

So, you can conclude that not all artificial sweeteners result in weight gain. Erythritol is completely safe in terms of weight gain scenarios. So, next time when someone asks you, “Does erythritol cause weight gain?” you’ll have a befitting answer for it. 

Does Erythritol Have Calories?

Erythritol, being the common substitute for sugar, is presumed to have a high number of calories in it. But, to your astonishment, you must know that sugar only has four calories, while erythritol has zero. So, you must omit sugar for weight loss practices and replace it with the best healthy alternative, erythritol. 

How Much Erythritol Is Too Much?

There are no official statements on the consumption rate of erythritol by any health departments. But, medical experts and researchers have stated that most people can handle around one gram of erythritol for every kilogram of their body weight. 

So, if you weigh 70 kilograms, you’ll be able to tolerate 70 grams of erythritol daily. 

Does Erythritol Cause Bloating?

To some extent, if you’re overconsuming erythritol, then it might trigger bloating symptoms. 10% of erythritol still travels down to the colon and might cause a problem if you have no limits on what quantity you consume daily.

Is There a Downside To Erythritol?

As 10% of erythritol goes down to the colon of your body, overconsumption can lead to digestive issues, diarrhea, bloating, gas, headache, nausea, and other mild side effects.

They’re rare and occur mostly when you’re too much dependent on erythritol for sweetening your food items. There are low-dosage medications to cure these mild adversities. 

Do Sugar Alcohols Make You Gain Weight?

Sugar alcohols don’t have much of calories or carbohydrates but aren’t completely free of them. So, limited and advised consumption of erythritol might not lead you to gain excessive weight. But too much erythritol can eventually be one of the many reasons for weight gain. 

Does Erythritol Make You Retain Water?

Erythritol has evidence of moisture retention. Sugar alcohol retains water in your intestines because the human body attempts to digest all of these additives. 


If you’re concerned about whether erythritol will contribute to your weight gain, then the confusion ends here! Erythritol, when consumed right, will help you manage your weight and be part of your weight loss diet. 

We have tried to cover all important aspects of erythritol for you to understand the benefits and drawbacks of its consumption. If you want a perfect alternative to sugar to eliminate its adverse effects, erythritol is the right pick! 

If you’re overdosing on erythritol and are finding it bad for your digestive system, then it’s just because of the dosage and not the sweetener.
