Chewing sugar-free gum while fasting can make it easier to stick with a fasting schedule. This article will discuss the best gums to have while fasting and the ones you should avoid to get better results.
Highlights
Intermittent fasting focuses on when you eat, not what you eat.
Regular gum often contains sugar and calories, while sugar-free options use artificial sweeteners.
Sugar-free gum with minimal calories is acceptable during fasting.
Different types of gum have varying nutritional profiles.
Chewing gum offers many health benefits, including appetite control and stress reduction.
Can You Chew Gum While Fasting?
Intermittent fasting, a common method to improve your health and manage weight, revolves around when you eat rather than what you eat [1].
In Intermittent fasting, you need to avoid calories, even the small numbers found in chewing gums.
So, does it mean that we cannot chew gum while fasting? Well, you can, but there are essential things to know and consider, especially the gum’s calorie and sugar content.
Dr. Jason Fung:
"Chewing sugar-free gum during fasting is generally acceptable and can help manage hunger and keep your breath fresh. However, it's best to avoid gum with sugar as it can cause an insulin response."

Most Gums Contain Sugar and Calories
One of the most important points about chewing gum while fasting is that most regular gums contain sugar and calories, which are both banned during fasting.
When we think of gum, we often imagine it as a calorie-free way to freshen our breath. However, most types of regular gum contain calories.
[cta-gocarnivore-plans]
The small number of calories found in a stick of gum comes from sugar, and these small amounts of sugar and calories can impact blood sugar levels and insulin response [2].
Consuming sugar, which is high in calories, can interrupt the fasting state. When sugar is ingested, our body releases insulin to manage the increased blood glucose levels.
This release of insulin shifts the body from a fasting state to a fed state, hindering the benefits of intermittent fasting [3].
Even a small amount of sugar from gum can prompt this shift. So, it’s important to find chewing gums with minimal or zero sugar content. But how many calories and carbs and how much sugar and fiber are there in regular gums?
"If you chew gum while fasting, choose a sugar-free variety. While there may be a minimal insulin response, it’s unlikely to break your fast, especially if it helps you stay on track."
Gum Nutritional Value
The following table shows the nutritional value of regular chewing gum [4].

Types of Gum
Gum isn't just for freshening your breath! There are different kinds out there, each with its own nutritional value. Understanding these specifics allows us to find the gums with minimal negative effects on fasting results.
Let's compare three popular types: sugar-free, zero-calorie, and nicotine gums [5].

As you see in the table, sugar-free gums have the lowest sugar content, so can we chew sugar-free gums, or can they interrupt fasting?
Can Sugar-Free Gum Break Intermittent Fasting?
The short answer is no. Sugar-free gums offer a low-calorie alternative with artificial sweeteners like aspartame, sorbitol, or xylitol, providing a calorie-free option and containing less than 5 calories per piece.
The body's response to such a small caloric intake is minimal, and it does not trigger the metabolic changes that break a fast, such as significant insulin release.
Also, a recent study examining the impact of low-calorie sweeteners such as aspartame suggests they do not significantly influence blood glucose or insulin response, supporting the idea that sugar-free gum is unlikely to break a fast [6][7].
[cta-meal-plan]
This makes sugar-free gum a viable option for those practicing intermittent fasting or trying to reduce caloric intake, as maintaining stable blood sugar levels is key to achieving the benefits of fasting [8].
So, sugar-free gum does not break intermittent fasting, but can chewing gum stop autophagy?
A study published in the "Journal of Clinical Endocrinology & Metabolism" found that sugar-free gum caused a minimal increase in insulin levels, which is unlikely to significantly affect fasting.
Does Chewing Gum Stop Autophagy?
Autophagy is like the body's recycling system for cells. It helps get rid of damaged or old cells and keeps cells healthy, which is crucial for making sure our cells function properly.
Intermittent fasting boosts autophagy and enables the body to clean up cells even more. But here's the catch: eating can slow down this cleaning process.
Research shows that consuming even one or two calories can stop autophagy. This happens because nutrients signal our body to stop cleaning (autophagy) and start digesting food, which ruins fasting benefits.
[cta-gocarnivore-plans]
So, during fasting or when you want autophagy to happen, it's best to avoid consuming calories. The number of calories found in chewing gum might not seem like much, but it can still mess up autophagy [9] [10].
However, chewing gum while fasting can bring various health benefits.
Gum offers some surprising scientifically proven health benefits, including reducing hunger, improving oral health and concentration, decreasing stress, freshening your breath, and helping you quit smoking.
Gum Reduces Hunger
Chewing gum before eating can reduce hunger and make it easier to manage your appetite. Because it tricks the brain into thinking you're eating, which can temporarily satisfy cravings [11] and help you control hunger while fasting.
Chewing Gum Can Curb Hunger
Research in the "Appetite" journal indicated that chewing gum can help reduce feelings of hunger, making it easier to adhere to fasting protocols.
Gum Helps Improve Oral Health
Chewing sugar-free gum stimulates saliva production, which helps neutralize mouth acids, which in turn reduces tooth decay and improves overall oral health [12].
[cta-meetings]
Chewing Gum Can Improve Concentration and Alertness
Chewing gum can make you more alert and improve your thinking abilities by boosting attention and concentration. Because chewing increases blood flow to the brain, which can help keep you more focused [13].
Gum Can Help Reduce Stress
Chewing a stick of gum can also act as a stress reliever, helping to reduce the stress hormone - cortisol - levels and provide a sense of calm and relaxation [14].
Gum Freshens Your Breath
Chewing gum freshens breath by cleaning the mouth, removing odor-causing bacteria, and improving oral hygiene, which is a nice thing for those who try intermittent fasting and worry about bad breath.
[cta-meal-plan]
Chewing Gum Helps You Quit Smoking
Nicotine gum helps you quit smoking by lowering withdrawal symptoms and cravings for cigarettes [15].
So, to choose the best chewing gums for intermittent fasting, you need to consider the following points.
Chewing Gum Can Improve Oral Health
According to a study in the "Journal of Dental Research," chewing sugar-free gum can improve oral health by increasing saliva flow and reducing plaque, which is beneficial during fasting periods.
Tips for Buying Chewing Gums for Intermittent Fasting
Please note that sugar isn't the only factor to consider when choosing chewing gums for fasting. Some sugar-free gums may contain other ingredients that could affect your fasting state. So, what are the other important factors?
Choose low-calorie gums: If you're trying intermittent fasting to lose weight, you should choose low- or zero-calorie gums. Although sugar-free gums are lower in calories, it's still important to check the calorie content.
Choose gums with artificial sweeteners: Gums sweetened with artificial sweeteners like aspartame, sucralose, or xylitol can provide the sweetness you crave without the caloric load, as they have minimal impact on blood sugar and insulin levels [16] [17].
Choose gums with natural ingredients: Gums sweetened with stevia or erythritol are a great choice for those who prefer natural sweeteners, as they are low in calories and have a minimal effect on blood sugar and insulin levels [18].
Choose sugar-free gums: Sugar-free gum can help you avoid the negative impacts of added sugar on insulin levels and caloric intake.
