Can You Chew Gum While Intermittent Fasting?

Intermittent fasting has become a popular way to lose weight and improve overall health. It involves restricting food intake for a set period, followed by a period of eating. While the rules of intermittent fasting may seem straightforward, questions still arise regarding what is allowed during the fasting period. One common question is whether or not chewing gum is allowed while intermittent fasting. In this article, we’ll explore the topic in detail.

What is Intermittent Fasting?

Intermittent fasting is a pattern of eating that involves restricting food intake for a set period of time. There are several different methods of intermittent fasting, but the most popular ones include:

  • The 16/8 method: Eating within an 8-hour window and fasting for 16 hours.
  • The 5:2 method: Eating normally for five days and restricting calorie intake to 500-600 calories for two non-consecutive days.
  • The Eat-Stop-Eat method: Fasting for 24 hours once or twice a week.

Can You Chew Gum While Intermittent Fasting?

The answer to this question depends on the type of gum you are chewing. If you are chewing sugar-free gum, then it is generally safe to chew gum while intermittent fasting. Sugar-free gum typically contains no calories and will not break your fast. However, if you are chewing gum that contains sugar or calories, then it will break your fast and negate the benefits of intermittent fasting.

It is also important to note that chewing gum can cause an insulin response in some people. This insulin response can cause your body to start storing fat, which is not ideal when trying to lose weight. If you find that chewing gum causes you to feel hungry or crave food, then it is best to avoid it during your fasting period.

The Benefits of Chewing Gum While Intermittent Fasting

Chewing gum while intermittent fasting can have some benefits. Firstly, it can help to freshen your breath and reduce bad breath, which is common during fasting periods. Additionally, chewing gum can help to reduce hunger pangs and cravings, which can make it easier to stick to your fasting plan. Finally, chewing gum can help to stimulate saliva production, which can aid in digestion.

The Downsides of Chewing Gum While Intermittent Fasting

While there are some benefits to chewing gum while intermittent fasting, there are also some downsides to consider. As previously mentioned, chewing gum can cause an insulin response in some people, which can lead to weight gain. Additionally, chewing gum can cause digestive issues, such as bloating, gas, and stomach cramps. If you experience any of these symptoms while chewing gum during your fasting period, it is best to avoid it.

The Bottom Line

In conclusion, chewing sugar-free gum is generally safe while intermittent fasting. However, it is important to consider the downsides of chewing gum, such as the insulin response and digestive issues. If you find that chewing gum helps you to stick to your fasting plan and does not cause any negative side effects, then it is fine to continue doing so. However, if you experience any negative side effects, it is best to avoid it. Ultimately, the key to successful intermittent fasting is finding what works best for your body and lifestyle.

Frequently Asked Questions

1. Is chewing gum allowed during intermittent fasting?

Chewing gum while intermittent fasting is a topic of debate among fitness enthusiasts. Some say it is okay, while others say it breaks the fast. The answer to this question ultimately depends on the type of fasting you are doing and your goals.

Chewing gum that is calorie-free and sugar-free is generally considered safe while fasting. However, if you are following a strict fasting regime, it is best to avoid chewing gum altogether as even the act of chewing can signal your body to start digesting food.

2. Will chewing gum affect my fasting results?

If you are using intermittent fasting as a weight loss tool, chewing gum is unlikely to have a significant impact on your results. However, if you are fasting for other health reasons, such as to improve insulin sensitivity, chewing gum may impact your results.

Chewing gum can stimulate the release of insulin, which can interfere with the metabolic benefits of fasting. Additionally, some artificial sweeteners used in sugar-free gum may trigger an insulin response even though they contain no calories.

3. Can I use gum to control my hunger during fasting?

Gum can be a useful tool for controlling hunger during fasting. Chewing gum can help reduce appetite and distract you from food cravings. However, it is important to choose sugar-free and calorie-free gum to avoid breaking your fast.

Keep in mind that relying too heavily on gum to control hunger can be counterproductive in the long run. Addressing the underlying causes of hunger, such as nutrient deficiencies, stress, or lack of sleep, is a more sustainable approach to fasting and weight loss.

4. How does gum affect my oral health during fasting?

Chewing gum can have both positive and negative effects on oral health during fasting. On the one hand, sugar-free gum can help stimulate saliva production, which can neutralize acids in the mouth and reduce the risk of cavities.

On the other hand, excessive gum chewing can lead to jaw pain and tooth wear. Additionally, some sugar-free gums contain acidic flavorings that can erode tooth enamel over time.

5. What are some alternatives to gum during fasting?

If you are looking for alternatives to gum during fasting, there are several options to consider. Drinking water, herbal tea, or black coffee can help suppress appetite and keep you hydrated. Snacking on low-calorie, nutrient-dense foods like vegetables and fruit can also help satisfy hunger without breaking your fast.

Finally, taking a short walk, practicing deep breathing, or engaging in a relaxing activity like yoga or meditation can help reduce stress and control hunger during fasting.

Can you chew gum while intermittent fasting?


In conclusion, chewing gum while intermittent fasting may not be the best idea. Although it may seem harmless, the act of chewing gum can trigger the digestive system and cause insulin levels to rise, breaking the fast. Additionally, many types of gum contain artificial sweeteners or sugar alcohols, which can also disrupt the fasting state.

However, if you must chew gum while fasting, it’s best to opt for sugar-free gum that doesn’t contain any artificial sweeteners or sugar alcohols. It’s also important to note that chewing gum shouldn’t take the place of water or other hydrating fluids during the fasting period.

Ultimately, the decision whether or not to chew gum while intermittent fasting is up to you. Consider the potential risks and benefits and make an informed decision based on your personal goals and health needs. And as always, it’s best to consult with a healthcare professional before starting any new diet or fasting regimen.
