Let’s be honest: Most of us spend way more time sitting than we’d like to admit. Whether you’re grinding through emails at your desk, binge-watching your favorite show on the couch, or stuck in traffic during your commute, sitting has become the default mode of modern life.
But here’s the good news: you don’t have to resign yourself to a completely sedentary existence. If you’re wondering how to burn calories while sitting, science shows there are legitimate strategies that can help you burn an extra 600+ calories per day without leaving your chair.
15 Ways to Burn Calories While Sitting:
- Master the art of fidgeting (100-800 cal/day)
- Perfect your posture (50+ cal/day)
- Chew sugar-free gum (33 cal for 3 hours)
- Drink ice cold water (70 cal/day)
- Use desk exercise equipment
- Laugh more (10-40 cal per 15 min)
- Drink green tea or black coffee
- Turn down the thermostat (140 cal/day at 61°F)
- Do seated exercises between tasks
- Use a stability ball chair
- Take deep breathing breaks
- Gesture while you talk
- Eat protein-rich snacks
- Contract and release muscles
- Set movement reminders every 30-60 minutes
Before we dive into the strategies, let’s set realistic expectations. You’re not going to burn 500 calories sitting in your office chair doing nothing (sorry!). But according to research from Harvard Medical School, what scientists call Non-Exercise Activity Thermogenesis (NEAT) can account for 15 to 30 percent of your daily calorie expenditure. That’s actually huge.
A study published in the Journal of Exercise Nutrition & Biochemistry found that differences in NEAT can account for up to 2,000 calories per day between individuals of similar body size. The cumulative effect of these small movements throughout your day adds up more than you’d think.
What Exactly is NEAT?
NEAT (Non-Exercise Activity Thermogenesis) refers to all the calories you burn through everyday activities that aren’t sleeping, eating, or formal exercise. Think typing, fidgeting, gesturing while you talk, even chewing gum. Research from the Mayo Clinic shows that NEAT is modulated by your energy balance and can be a critical component in how you maintain body weight or develop obesity.
The Science of Sitting and Calorie Burn
According to Harvard Health Publishing, sitting at your desk burns approximately 80 to 85 calories per hour for most adults. While standing only burns about 88 calories per hour, just 8 calories more than sitting. So standing desks aren’t the magic bullet many people hoped for.
The real opportunity lies in what you do while you’re sitting. Let’s explore the science-backed methods that can genuinely increase your calorie burn throughout the day.
How to Burn Calories While Sitting: 15 Science-Backed Methods
1
Master the Art of Fidgeting
Your parents might have told you to stop fidgeting, but science says they were wrong. Research published in the American Journal of Clinical Nutrition found that fidgeting-like activities can burn anywhere from 100 to 800 calories per day depending on the individual.
A study from the National Institute of Health analyzing the UK Women’s Cohort Study discovered that women who reported high levels of fidgeting while sitting for 7+ hours per day had no increased mortality risk, while those who didn’t fidget had a 30% increase in all-cause mortality risk.
Try these fidgeting techniques:
- Bounce your leg or tap your foot to music
- Drum your fingers on your desk
- Shift your weight from side to side in your chair
- Do seated torso twists periodically
- Squeeze a stress ball or use hand grippers
2
Perfect Your Posture
Sitting up straight isn’t just about looking professional. Maintaining good posture while sitting works the muscles in your upper body, shoulders, and back. This constant engagement strengthens your core and promotes additional calorie burn because you’re exerting more effort to keep your body straight and upright, requiring continuous muscle contraction to maintain proper alignment.
Think of it as a mini-workout happening in the background while you work. Your postural muscles are contracting continuously to hold you upright, which requires energy.
3
Chew Sugar-Free Gum
This one might sound too simple to be true, but the science backs it up. A study published in the New England Journal of Medicine by Mayo Clinic researchers found that chewing gum increases energy expenditure by about 19% above baseline values, burning approximately 11 calories per hour. Just make sure you’re chewing sugar-free gum to keep those calories down and fat burning tuned up.
More recent research published in Science Advances found that chewing increases metabolism by 10-15% depending on the stiffness of what you’re chewing. When you chew gum, your metabolic rate rises as your jaw muscles work and energy is expended.
Bonus benefit: Research from the University of Rhode Island showed that people who chewed gum consumed 68 fewer calories at lunch and didn’t compensate by eating more later in the day. Gum chewers also burned about 5% more calories overall than non-gum chewers.
4
Drink Ice Cold Water
Your body has to work to warm cold water up to your core temperature, and that work burns calories through a process called thermogenesis. According to research published in the Journal of Clinical Endocrinology and Metabolism, drinking 500 ml of water increased metabolic rate by 30% for up to 40 minutes after consumption.
The study found that about 40% of this thermogenic effect came specifically from warming the water from room temperature to body temperature. While one glass of ice water only burns about 8 calories, drinking eight glasses per day adds up to roughly 70 extra calories burned.
A 2013 study published in the Journal of Clinical and Diagnostic Research found that drinking 1.5 liters of water beyond normal intake resulted in meaningful weight loss in overweight subjects over an 8-week period.
5
Use Desk Exercise Equipment
Desk exercise equipment like under-desk ellipticals, foot pedals, resistance bands, or balance boards can significantly boost your calorie burn while sitting. Research published in the British Journal of Sports Medicine shows that workplace interventions promoting physical activity can effectively reduce sitting time and increase energy expenditure throughout the workday.
These devices allow you to unconsciously burn calories while simultaneously increasing productivity and alertness. If you’re serious about burning calories at work, you might even consider something unique like the punching bag keyboard that gets you moving while you type.
6
Laugh More (Seriously)
This might be the most enjoyable calorie-burning strategy on the list. A 2007 study published in the International Journal of Obesity found that genuine laughter increases your energy expenditure and heart rate by 10-20% above resting levels. Just 10 to 15 minutes of genuine laughter can burn 10 to 40 additional calories.
Watch comedy shows during lunch, listen to funny podcasts while working, or join virtual hangouts with friends who make you laugh. Your abs will thank you too.
7
Drink Green Tea or Black Coffee
Green tea contains catechins (a type of antioxidant) that work with caffeine to increase your metabolic rate, making you burn more calories even at rest. Research published in the American Journal of Clinical Nutrition found that green tea extract significantly increased 24-hour energy expenditure and fat oxidation.
Green tea also contains theanine, an amino acid that helps you stay mentally calm yet alert, which is perfect for desk work. If you substitute 1-2 cups of green tea for a can of soda daily, you could avoid more than 50,000 calories over the next year. Learn more about the health benefits of green tea.
Black coffee (without cream and sugar) produces similar metabolic effects through caffeine alone. Curious about how coffee can boost your longevity?
8
Turn Down the Thermostat
This one’s fascinating: being slightly cold forces your body to burn extra calories to maintain its core temperature. Research published in Cell Metabolism shows that shivering thermogenesis can increase your metabolic rate up to 5 times your resting level at peak intensity.
But you don’t need to shiver to see benefits. Research published in the Journal of Applied Physiology found that 10 days of cold exposure at 60°F for 6 hours per day led to a 37% increase in brown fat volume. Brown adipose tissue (BAT) is a special type of fat that burns calories to generate heat.
A shorter trial lasting just 3 days at a continuous 61°F showed an added calorie burn of around 140 calories per day. According to research in the American Journal of Physiology, researchers estimate that 65°F is roughly the highest temperature where you’d still see metabolic benefits from non-shivering thermogenesis.
Note: Don’t go overboard. The goal is to be slightly cool and comfortable, not uncomfortably cold. Nearly 50% of the calories you burn go toward maintaining core temperature. Learn more about natural ways to boost your metabolism for additional strategies.
9
Do Seated Exercises Between Tasks
You don’t need to leave your chair to get your muscles working. Simple seated exercises can elevate your heart rate and burn extra calories throughout the day.
Try these seated exercises:
- Seated leg lifts: Extend your legs until they’re level with your hips and hold for 10 seconds
- Chair dips: Place hands on armrests and lift your body up slightly
- Seated torso twists: Twist your upper body side to side
- Desk push-ups: Place hands on desk edge and do push-ups at an angle
- Shoulder shrugs and rolls: Roll shoulders backward and forward
- Ankle circles: Rotate ankles clockwise and counterclockwise

According to research, these micro-workouts add up. Even performing these movements for just 2-3 minutes between tasks can significantly increase your daily calorie expenditure.
10
Use a Stability Ball Chair
Swapping your regular office chair for a stability ball forces your core muscles to engage continuously to maintain balance. While research shows the exact calorie burn varies, early studies found that sitting on a yoga ball burned about 4.1 more calories per hour than sitting in an office chair, while other studies suggest a 10% higher burn rate.
The extra caloric burn likely comes from a combination of fidgeting (dynamic sitting) and using more of your leg and core muscles to stay balanced. Plus, you can use the ball for quick strength-training exercises during breaks.
11
Take Deep Breathing Breaks
While breathing is automatic, intentional deep breathing exercises actually require more energy than shallow breathing. Deep diaphragmatic breathing engages your core muscles and increases oxygen intake, which slightly elevates your metabolic rate.
Try this: Set a timer to go off every hour. Take 10 deep belly breaths, inhaling for 4 counts, holding for 4, and exhaling for 6. This not only burns a few extra calories but also reduces stress and improves focus.
12
Gesture While You Talk
If you’re on phone calls or video meetings throughout the day, use hand gestures while you speak. Moving your arms and hands engages your upper body muscles and burns more calories than sitting perfectly still.
This falls under NEAT, and according to research from the American Physiological Society, these seemingly minor movements can add up to substantial calorie expenditure over time. If you’re someone who talks with your hands naturally, you’re already ahead of the game!
13
Eat Protein-Rich Snacks
This technically happens after you’ve already eaten, but choosing high-protein snacks while sitting boosts your metabolism through something called the thermic effect of food (TEF). Your body burns calories digesting food, and protein has the highest thermic effect of all macronutrients.
According to Harvard Health, your body uses about 10% of calories consumed to digest and process food. But with protein, that number jumps to 20-30%, meaning your body burns significantly more calories processing a protein-rich snack than it would processing carbs or fats.
Smart sitting snacks: Greek yogurt, hard-boiled eggs, string cheese, almonds, beef jerky, or protein shakes. These keep you full longer while your body works harder to digest them. Looking for more protein ideas? Check out our guide on the best sources of lean protein and quick healthy snacks.
14
Contract and Release Your Muscles
This technique, called isometric exercises, involves contracting specific muscles without moving your joints. You can do this discreetly while sitting anywhere, from your office to an airplane to your couch.
Try these invisible exercises:
- Glute squeezes: Tighten your butt muscles, hold for 10 seconds, release. Repeat 10 times.
- Ab vacuums: Suck in your stomach as if trying to touch your belly button to your spine. Hold for 10-15 seconds.
- Thigh squeezes: Press your thighs together as hard as you can, hold, release.
- Calf raises: While seated, lift your heels off the ground onto your toes, hold, lower.
These exercises engage your muscles, which requires energy (calories) and helps maintain muscle mass, which in turn keeps your metabolism higher.
15
Set Movement Reminders
The longest you should sit without any movement is about 30-60 minutes. Use technology to your advantage by setting hourly reminders to stand up, stretch, or do a quick activity.
According to the Centers for Disease Control and Prevention, breaking up prolonged sitting with even brief movement breaks significantly improves metabolic health markers. While standing only burns about 8 more calories per hour than sitting, the act of transitioning between positions and moving around burns additional calories.
Consider using apps or fitness trackers that remind you to move. Even a 2-minute walk to get water or a quick set of stretches resets your metabolism and breaks the sedentary pattern. Want to maximize your movement? Learn about walking for fat loss.
Putting It All Together: Your Daily Calorie-Burning Plan
Here’s the thing: none of these strategies alone will transform your physique or health. But that’s not the point. The power lies in combining multiple strategies throughout your day.
Let’s do some math. If you:
- Fidget consistently throughout the day (300 extra calories)
- Maintain good posture (50 extra calories)
- Chew gum for 3 hours (33 extra calories)
- Drink 8 glasses of ice water (70 extra calories)
- Keep your environment at 65°F (100 extra calories)
- Do seated exercises 3 times (50 extra calories)
- Laugh during lunch (20 extra calories)
That’s an extra 623 calories burned in a single day, just from small adjustments to how you sit. Over a week, that’s 4,361 calories. Over a month, that’s 18,690 calories, which equals about 5.3 pounds of fat. Serious about weight loss? Check out our guides on how to lose 10 pounds and how to lose the last 10 pounds.
The Real Power of NEAT
According to research published in Mayo Clinic Proceedings, NEAT can vary by up to 2,000 calories per day between individuals of similar body size, depending primarily on occupation and lifestyle choices. This means the cumulative effect of these small movements can have a genuine impact on long-term weight management.
Beyond Calorie Burn: Additional Health Benefits
While burning extra calories is great, these strategies offer benefits that extend far beyond the scale:
Improved circulation: Movement, even subtle fidgeting, keeps blood flowing and prevents the pooling that can occur during prolonged sitting.
Better focus and productivity: Studies show that people who incorporate movement breaks and maintain good posture have better cognitive function and sustained attention.
Reduced risk of chronic disease: A study in the Journal of Exercise Nutrition & Biochemistry found that even 15 minutes per day of low-volume physical activity reduced risk of all-cause mortality by 14% and increased life expectancy by three years.
Lower stress levels: Many of these techniques, particularly deep breathing and laughter, activate your parasympathetic nervous system, reducing cortisol and promoting relaxation.
Better metabolic health: Breaking up sitting time improves insulin sensitivity and glucose metabolism, according to research published in Diabetes Care.
Frequently Asked Questions About Burning Calories While Sitting
Can you really burn calories while sitting down?
Yes! While sitting burns about 80-85 calories per hour on its own, you can significantly increase this through NEAT (Non-Exercise Activity Thermogenesis) activities like fidgeting, maintaining good posture, and doing subtle movements. Studies show these small activities can burn an additional 100-800 calories per day depending on how consistently you implement them.
How many calories can I burn sitting at my desk all day?
A typical 8-hour workday of sitting burns approximately 640-680 calories on its own. However, by implementing the strategies in this article—such as fidgeting, drinking cold water, maintaining good posture, and doing seated exercises—you can burn an additional 400-600 calories per day, bringing your total to over 1,000 calories.
What burns the most calories while sitting?
Fidgeting is the single most effective calorie-burning activity while sitting, with the potential to burn 100-800 calories per day. Cold exposure (keeping your environment at 61-65°F) is second, burning approximately 100-140 extra calories daily. Combining multiple strategies yields the best results.
Does drinking cold water while sitting burn calories?
Yes! Your body burns calories through thermogenesis to warm cold water to body temperature. Research shows that drinking 500ml of cold water increases metabolic rate by 30% for up to 40 minutes. Drinking eight glasses of ice water per day can burn approximately 70 extra calories.
Is sitting and fidgeting good for weight loss?
Fidgeting can contribute to weight loss as part of an overall healthy lifestyle. Research published in the American Journal of Clinical Nutrition found that fidgeting can burn 100-800 calories per day. Over time, this can contribute to meaningful weight loss—potentially 1-2 pounds per month from fidgeting alone.
How long should I sit before taking a break?
According to the CDC, you should take movement breaks every 30-60 minutes of sitting. Even brief 2-3 minute breaks to stand, stretch, or walk significantly improve metabolic health markers and help prevent the negative effects of prolonged sitting.
Can good posture help burn more calories?
Yes! Maintaining proper posture engages your core, back, and shoulder muscles continuously, which requires energy. While the exact calorie burn varies, engaging these postural muscles can burn an estimated 50+ additional calories per day compared to slouching.
Does chewing gum actually burn calories?
Yes! Research published in the New England Journal of Medicine found that chewing gum burns approximately 11 calories per hour—about 19% more than baseline. Chewing gum for 3 hours per day can burn around 33 extra calories, and studies show gum chewers also tend to consume fewer calories at meals.
The Bottom Line on Burning Calories While Sitting
Let’s be real: sitting all day isn’t ideal. The human body evolved to move. But if your job, commute, or lifestyle means you’re sitting for extended periods, you’re not doomed to poor health or unwanted weight gain.
The research is clear: small, consistent movements throughout the day genuinely burn calories and improve health outcomes. You don’t need to run marathons or spend hours at the gym to make a difference. Sometimes, the most sustainable changes are the ones that fit seamlessly into your existing life.
Start with one or two strategies from this list. Maybe you’ll keep a pack of sugar-free gum in your desk drawer and turn your thermostat down a degree or two. Maybe you’ll set an hourly reminder to do some seated leg lifts. The key is consistency, not perfection.
Your body is burning calories right now as you read this. With a few strategic tweaks to how you sit, you can turn that burn into something more substantial. And who knows? You might find yourself feeling more energized, focused, and healthy in the process.
Remember: These strategies work best when combined with a balanced diet and regular physical activity. If you’re looking to make significant changes to your health or weight, consider consulting with a healthcare provider or registered dietitian who can provide personalized guidance based on your individual needs and goals.
