The Truth Behind the Calorie Count
The idea that chewing gum can burn a meaningful number of calories has been a topic of interest for years. The widely cited figure of 11 calories per hour originates from a study involving a very vigorous chewing pace that is not typical for the average person. Normal, relaxed chewing burns a much smaller amount, often closer to 3 to 5 calories per hour. While any muscle movement contributes to energy expenditure, relying on gum chewing for significant calorie burn is misleading.
The energy expenditure from chewing gum is categorized as Non-Exercise Activity Thermogenesis (NEAT). This is the energy expended for everything we do that is not sleeping, eating, or sports-like exercise. The jaw muscles, known as masseter muscles, are powerful, and their repeated use does increase your metabolic rate, but only slightly. The calorie burn is real, but its impact on your overall weight loss goals is minor.
How Your Body Burns Calories While Chewing
When you chew, your jaw muscles contract, requiring energy. This energy is derived from calories. A 2022 study published in Science Advances found that chewing gum increased metabolic rates by 10-15% above basal levels, with stiffer gum causing a more significant boost than softer gum. While this sounds impressive, remember that it's a percentage increase on a very low baseline, so the total calories burned remain low. Additionally, chewing can stimulate the cephalic-vagal reflex, which is the body's response to the sight and smell of food. This can increase gut motility and digestive hormone secretion, further contributing to a minor metabolic increase, even without actual food consumption.
Comparing Chewing Gum with Other Activities
To put the calorie burn from chewing gum into perspective, consider how it stacks up against other everyday activities. The following table provides a comparison based on an hour of each activity, for an average person.
| Activity | Estimated Calories Burned (per hour) | Notes |
|---|---|---|
| Chewing Gum (Normal) | ~3–5 calories | Low intensity, minimal effort. |
| Chewing Gum (Vigorous) | ~11 calories | Requires a rapid, intense pace. |
| Sitting Still | ~60–80 calories | Resting metabolic rate (varies by person). |
| Walking (Casual) | ~150–250 calories | Standard pace, moderate effort. |
| Typing | ~40 calories | Light office work. |
| Standing at a Desk | ~100 calories | Burns more than sitting. |
As the table clearly shows, the caloric output from chewing gum is trivial compared to even light physical activity. It is a supplement, not a substitute, for exercise.
The Limitations and Downsides
Using chewing gum as a primary weight loss strategy is a flawed approach for several reasons. First, the calorie burn is so minimal that it will have virtually no impact on your overall weight, and any benefits are far outweighed by a healthy diet and regular exercise. Secondly, relying on gum can create a false sense of accomplishment, leading to a neglect of more effective fitness strategies.
Additionally, there are some potential drawbacks to excessive gum chewing:
- Digestive Issues: Many sugar-free gums contain sugar alcohols like sorbitol, which are not fully absorbed by the small intestine. Consuming these in large quantities can lead to bloating, gas, and diarrhea.
- Dental Concerns: While sugar-free gum can promote oral health, regular gum is high in sugar, which can contribute to tooth decay and other dental problems.
- Jaw Strain: Constant, vigorous chewing can lead to temporomandibular joint (TMJ) disorders, causing pain and discomfort in the jaw.
- Increased Air Swallowing: Chewing gum can cause you to swallow more air, potentially leading to bloating and abdominal discomfort.
The Real Benefits of Chewing Gum Beyond Calories
While its calorie-burning effect is minor, chewing gum offers other health benefits that are worth noting. For weight management, the most significant advantage is behavioral. Chewing gum can be a useful tool for curbing cravings and avoiding mindless snacking. For instance, a stick of gum can serve as a calorie-free distraction when the urge for an unhealthy snack arises.
Here are some of the scientifically supported benefits of chewing gum:
- Appetite Control: Studies have shown that chewing gum can help suppress appetite, especially for sweet or salty snacks.
- Curbing Cravings: Popping a piece of gum after a meal can signal to your brain that eating is over, preventing you from reaching for dessert.
- Enhanced Memory and Alertness: Chewing gum can boost blood flow to the brain, which may help improve memory and combat feelings of sleepiness.
- Oral Health: Chewing sugar-free gum for 20 minutes after eating can increase saliva flow, which helps wash away food particles and neutralize acids, protecting against cavities.
Conclusion
So, can chewing gum for an hour burn calories? Yes, but the number is minimal, and it is not a viable strategy for significant weight loss. Think of it as a very small, supplementary activity, not a centerpiece of your fitness plan. Its true value lies in its ability to aid with appetite control and curb unhealthy snacking, especially when used in conjunction with a balanced diet and regular exercise.
Incorporating smart, sugar-free chewing into a broader healthy lifestyle can offer some modest benefits for both your waistline and your oral health.

However, the most effective path to a healthy weight remains a combination of a nutritious diet and consistent physical activity. The next time a craving hits, reach for a stick of gum, but don't forget to put on your walking shoes later. It’s the combination of small, smart choices that leads to lasting results.
