Does Chewing Gum Really Burn Calories? The Science Explained

Chewing gum has long been associated with fresh breath, reduced cravings, and even stress relief. But can this simple habit actually help you burn calories? Many people believe that the act of chewing gum can contribute to weight loss by increasing energy expenditure. But how much truth is there to this claim? Let’s explore the science behind chewing gum and its impact on calorie burning in depth.

The Mechanics of Chewing Gum and Energy Expenditure

The process of chewing gum involves continuous jaw movement, activating the muscles in the face and even engaging the nervous system to some extent. Every physical activity, even minor ones, requires energy, and chewing gum is no exception. This is part of what is known as non-exercise activity thermogenesis (NEAT), which encompasses all the calories burned through non-intentional physical movement such as fidgeting, pacing, or chewing.

Studies have shown that chewing gum does indeed burn calories, albeit in small amounts. Research from the Mayo Clinic suggests that chewing gum can increase energy expenditure by approximately 11 calories per hour. While this may not seem significant, it can add up over time, especially for habitual gum chewers.

A study published in The New England Journal of Medicine found that the act of chewing gum increased metabolic rate by 20%, meaning the body burns slightly more calories than it would at rest. However, compared to traditional exercises like walking or jogging, the calorie burn from chewing gum is minimal. For example, walking burns anywhere from 100 to 300 calories per hour, depending on speed and body weight.

Does the Type of Gum Matter?

Interestingly, the type of gum you chew may have a small influence on the number of calories burned. Here’s how different types compare:

  1. Regular Sugary Gum: Since these gums contain sugar and calories, they provide energy rather than contribute to calorie burning. Each piece of regular gum can contain 5 to 25 calories, meaning frequent consumption can add up over time.
  2. Sugar-Free Gum: These typically contain artificial sweeteners and have fewer calories. Some studies suggest that sugar-free gum may contribute to calorie burning because the body expends energy metabolizing sugar alcohols.
  3. Chewing Resistance and Hardness: Some gums are firmer and require more effort to chew, which could slightly increase the amount of calories burned. However, this effect is marginal and not a significant weight-loss tool.

The Role of Chewing Gum in Weight Management

Although chewing gum does not burn a significant number of calories, it has other benefits that may support weight management:

1. Appetite Suppression

Research has shown that chewing gum can reduce feelings of hunger and cravings. A study conducted by the University of Rhode Island found that participants who chewed gum consumed 68 fewer calories at lunch compared to those who didn’t. This suggests that gum might act as a mild appetite suppressant, potentially reducing overall caloric intake.

2. Prevention of Mindless Snacking

Many people snack out of boredom rather than hunger. Chewing gum may help prevent unnecessary snacking by keeping the mouth occupied. A 2011 study published in Appetite found that people who chewed gum were less likely to snack on high-calorie foods.

3. Slight Metabolic Boost

Although the metabolic increase from chewing gum is minor, it still contributes to overall daily energy expenditure. If paired with other healthy habits such as walking and proper diet, the cumulative effect may be beneficial for long-term weight management.

Psychological and Behavioral Benefits of Chewing Gum

Beyond its physical effects, chewing gum can have psychological benefits that indirectly contribute to weight control:

  • Stress Reduction: Stress is a common trigger for overeating. Some studies indicate that chewing gum can help reduce cortisol levels (the stress hormone), leading to lower stress-related eating.
  • Increased Focus and Concentration: Some research suggests that chewing gum improves cognitive function, which may help people stay mindful of their eating habits and avoid impulsive food choices.
  • Oral Fixation Management: For individuals trying to quit smoking or reduce unhealthy habits such as nail-biting, gum can serve as a substitute.

Potential Downsides of Chewing Gum

While chewing gum has benefits, excessive consumption may lead to negative effects, such as:

  1. Jaw Fatigue or Temporomandibular Joint (TMJ) Issues – Overuse of jaw muscles can lead to discomfort, pain, and potential jaw disorders.
  2. Digestive Discomfort – Many sugar-free gums contain artificial sweeteners like sorbitol, which can cause bloating, gas, and laxative effects in some individuals.
  3. Increased Sugar Intake – Sugary gums add unnecessary calories and may contribute to tooth decay if not balanced with proper oral hygiene.
  4. Gastrointestinal Issues – Constant gum chewing can lead to excessive air swallowing, which may result in bloating and discomfort.

Chewing Gum and Exercise Performance

Interestingly, some studies suggest that chewing gum could impact physical performance. A study in the Journal of Strength and Conditioning Research found that athletes who chewed gum before sprinting experienced a slight improvement in reaction time and alertness. This suggests that chewing gum might provide a mental edge during sports or high-performance activities, although the direct effect on calorie burning remains minimal.

Alternative Activities That Burn Similar Calories

If your goal is to find small ways to burn additional calories throughout the day, consider the following NEAT activities:

  • Standing Instead of Sitting: Standing burns approximately 50 more calories per hour than sitting.
  • Fidgeting: Tapping your foot, bouncing your leg, or shifting in your seat can increase calorie burn.
  • Pacing While on the Phone: Walking while talking on the phone can add up to hundreds of extra steps each day.
  • Using a Stability Ball Instead of a Chair: Sitting on a stability ball engages core muscles and slightly increases energy expenditure.

Conclusion: Is Chewing Gum a Good Calorie-Burning Hack?

Chewing gum does burn calories, but only in small amounts. While it may support weight management by reducing cravings and providing minor metabolic boosts, it is not a significant method for calorie burning. Instead of relying on gum as a weight-loss strategy, it should be used as a supplementary habit along with a balanced diet and regular exercise.

If you enjoy chewing gum, feel free to incorporate it into your routine, but don’t expect dramatic weight loss results. For effective weight management, prioritizing exercise, healthy eating, and mindful habits will always be the best approach.
