Chewing gum burns roughly 11 calories per hour, offering a small boost to your daily energy expenditure.
Understanding the Caloric Burn of Chewing Gum
Chewing gum might seem like a trivial activity, but it actually requires energy. The muscles involved in chewing contract repeatedly, and like any muscular activity, this burns calories. However, the amount is relatively modest compared to other physical movements.
The act of chewing engages the masseter muscle primarily, along with other smaller muscles around the jaw. This constant motion causes your body to expend energy to fuel these muscles. Although it’s not vigorous exercise, this subtle activity contributes to your total daily calorie burn.
On average, chewing gum for an hour burns about 11 calories. This number can vary based on factors such as chewing intensity, individual metabolism, and body weight. For instance, someone who chews vigorously may burn slightly more calories than someone who chews gently.
Calorie Expenditure Compared to Other Activities
To put chewing gum into perspective, it helps to compare it with other light activities. The table below shows estimated calories burned per hour for several low-intensity activities for an average adult weighing around 155 pounds (70 kg).
| Activity | Calories Burned per Hour | Description |
|---|---|---|
| Chewing Gum | 11 | Light jaw muscle activity only |
| Sitting and Reading | 50-70 | Minimal movement, relaxed posture |
| Standing Still | 88-100 | Slightly higher energy use than sitting |
| Walking Slowly (2 mph) | 140-200 | Mild aerobic activity at low pace |
This table highlights how minimal chewing gum’s calorie burn is compared to even passive activities like standing or reading. Still, every bit counts when accumulating daily calorie expenditure.
The Science Behind Muscle Activity and Energy Use in Chewing
Muscle contraction requires adenosine triphosphate (ATP), the body’s primary energy currency. When the jaw muscles contract during chewing, ATP breaks down to provide energy. This biochemical process consumes calories derived from carbohydrates and fats.
The masseter muscle can exert significant force during chewing—up to 200 pounds of pressure—but typical gum chewing uses only a fraction of that strength repeatedly over time. This repetitive motion leads to a slow but steady calorie burn.
Interestingly, studies using indirect calorimetry—a method measuring oxygen consumption and carbon dioxide production—show that metabolic rate slightly increases during gum chewing compared to resting states. This confirms that even small muscle movements contribute measurably to overall metabolism.
Factors Influencing Calories Burned While Chewing Gum
Chewing Intensity and Duration
The speed and force of chewing directly affect energy expenditure. Vigorous chewing requires more muscle power and thus more ATP consumption. People who chew quickly or with increased jaw tension will burn more calories than those who chew slowly or lightly.
Duration also matters; longer sessions naturally lead to higher total calorie burn. However, most people chew gum intermittently rather than continuously for hours.
Body Weight and Metabolism Variations
Individuals with higher body weight generally have higher basal metabolic rates (BMR), meaning their bodies use more energy even at rest. Consequently, heavier individuals tend to burn slightly more calories doing the same activity than lighter individuals.
Metabolic differences due to genetics or fitness level also influence how many calories are burned during any physical action—including chewing.
The Type of Gum Chewed
Some gums are harder or thicker than others, requiring more effort to chew. Sugar-free gums often contain ingredients that create a different texture compared to regular gums with sugar or sweeteners.
While the difference in caloric burn between types of gum isn’t dramatic, tougher gums may cause increased jaw muscle activation and thus marginally higher calorie expenditure.
The Role of Chewing Gum in Weight Management Efforts
Though the calorie burn from chewing is modest, some have explored whether gum can aid weight control by increasing overall metabolism or reducing hunger sensations.
Chewing gum can help curb appetite by stimulating saliva production and providing oral satisfaction without adding significant calories. Some studies suggest that people who chew gum between meals may consume fewer snacks or smaller portions later on.
However, relying solely on gum for weight loss isn’t practical since the energy expended is minimal—around 11 calories per hour at best—and won’t replace traditional methods like diet adjustments and exercise routines.
Still, it can be a helpful tool for some individuals seeking minor boosts or distractions from cravings without extra caloric intake.
Mouth Movements Beyond Chewing: How They Affect Energy Use
Jaw movement isn’t limited strictly to chewing; talking, yawning, and swallowing also involve muscle contractions that consume small amounts of energy.
Talking actively engages facial muscles including those around the mouth and jaw. Although talking burns more calories than simply sitting quietly due to continuous movement of lips and tongue along with breathing patterns, its total impact remains low compared with physical exercise.
Yawning involves opening the mouth widely with rapid inhalation; this action activates muscles but is brief in duration and doesn’t significantly increase calorie burn overall.
Swallowing is a complex reflex involving coordinated muscle contractions in the throat but occurs infrequently enough that its contribution to daily calorie use is negligible outside eating or drinking periods.
Combining these subtle activities throughout the day adds up slightly but remains minor relative to larger movements like walking or running.
The Jaw Muscle: Anatomy and Its Energy Needs During Chewing
The masseter muscle dominates jaw strength; it’s one of the strongest muscles relative to size in the human body. It works alongside temporalis and pterygoid muscles during mastication (chewing).
These muscles contract rhythmically when you chew gum—opening and closing your mouth repeatedly—to break down food or keep the gum moving between teeth surfaces.
Muscle fibers require oxygenated blood flow for ATP production through aerobic metabolism during sustained activity like continuous chewing. Though each contraction uses only a tiny amount of energy individually, thousands occur over time while you chew steadily—resulting in measurable caloric consumption.
Jaw muscle fatigue can occur after prolonged intense chewing since these muscles are not usually engaged continuously for long periods outside eating contexts. This fatigue limits how long someone might chew vigorously before needing rest breaks which also impacts total calories burned per session.
The Impact of Chewing Gum on Resting Metabolic Rate (RMR)
Resting metabolic rate represents how many calories your body burns at rest just maintaining vital functions such as breathing, circulation, and cellular repair.
Chewing gum slightly elevates RMR because it introduces mild muscular activity beyond complete rest. Research indicates RMR can rise by approximately 10-20% during active mastication compared with complete stillness without movement.
For example:
- Normal RMR: ~1500 kcal/day
- RMR increase from chewing: ~150-300 kcal/day if done continuously (hypothetically)
Since continuous chewing throughout an entire day is unrealistic for most people due to discomfort or practicality issues, actual increases are much smaller in real life scenarios—usually just a few extra calories burned per hour spent chewing rather than all day long.
The Influence of Saliva Production on Energy Use While Chewing Gum
Chewing stimulates saliva secretion which aids digestion by moistening food particles. Saliva production itself requires metabolic resources as glands actively secrete fluids containing enzymes like amylase.
This process adds marginally to total energy expenditure while chewing but does not significantly increase overall calorie burn beyond muscular work involved in mastication movements themselves.
Saliva helps maintain oral health by neutralizing acids produced by bacteria; however its role in increasing caloric output is minimal though measurable under laboratory conditions using precise metabolic measurements.
The Practical Takeaway: How Much Does Chewing Gum Really Help?
The bottom line is simple: if you chew gum for an hour nonstop—which nobody typically does—you’ll burn about 11 extra calories above resting levels. That’s roughly equivalent to walking an extra minute at a slow pace or climbing a few stairs once or twice during that time frame.
Incorporating gum-chewing into your day won’t replace exercise routines or dietary control needed for weight loss but may offer slight benefits such as:
- A mild metabolic boost through muscle activation.
- A tool for appetite control by reducing snacking urges.
- An easy way to keep your mouth busy without additional calorie intake.
- A potential aid against dry mouth thanks to increased saliva flow.
For those curious about squeezing every bit out of their metabolism during sedentary moments—like working at a desk or watching TV—gum offers an effortless option with no downside besides occasional jaw fatigue if overdone.
A Word on Jaw Health From Excessive Gum Chewing
While moderate amounts are harmless for most people, excessive gum-chewing can strain temporomandibular joints (TMJ) causing discomfort or pain known as TMJ disorder symptoms such as headaches or jaw clicking noises after prolonged use.
If you experience any persistent pain while chewing frequently throughout the day consider reducing frequency or consulting a dental professional specialized in TMJ issues for tailored advice on safe habits.

Frequently Asked Questions
Does Chewing Gum Significantly Increase Calorie Burn?
Chewing gum does burn calories, but the amount is quite small. On average, it burns about 11 calories per hour, which is minimal compared to other physical activities. It can contribute slightly to daily calorie expenditure but should not be relied on for weight loss.
What Muscles Are Involved In Burning Calories While Chewing?
The primary muscle used during chewing is the masseter muscle, along with smaller muscles around the jaw. These muscles contract repeatedly, requiring energy and causing a small calorie burn through this continuous activity.
How Does Chewing Intensity Affect Calorie Expenditure?
The intensity of chewing can influence the number of calories burned. Vigorous chewing requires more muscle activity and energy, leading to a slightly higher calorie burn compared to gentle chewing, though the difference remains modest overall.
Can Chewing Gum Replace Other Light Physical Activities For Calorie Burning?
While chewing gum does burn some calories, it is far less effective than other light activities such as standing or walking slowly. It offers only a minor boost in energy expenditure and should be combined with more active habits for meaningful calorie burn.
Why Does Chewing Gum Increase Metabolic Rate Slightly?
Chewing gum increases metabolic rate because muscle contractions require energy, which comes from breaking down ATP in the body. This process uses calories derived from carbohydrates and fats, causing a slight rise in metabolism during chewing.
The Bottom Line on Tiny Calorie Burns Adding Up Over Time
Small activities like chewing add up when combined with other minor movements throughout daily routines—fidgeting fingers tapping keyboards or feet bouncing while seated—all contribute marginally toward total daily energy expenditure known as non-exercise activity thermogenesis (NEAT).
Though negligible alone compared against formal workouts burning hundreds of calories per session—the cumulative effect over weeks/months could influence weight maintenance subtly if combined with better nutrition habits overall.
No single trick replaces balanced nutrition plus consistent physical activity—but understanding where tiny calorie burns come from helps appreciate how bodies work continuously—even when seemingly idle.
That said: grab some sugar-free gum if you want something simple keeping jaws busy while adding a pinch more fuel burned—even if just barely noticeable!
