How Many Calories Do You Burn When You Fart? | Gas Myths

Farting uses only a trace amount of energy, so calories burned from gas release are far too small to change body weight.

Calories Burned From Farting During The Day

The catchy claim that one gas release burns 67 calories pops up in memes, comment threads, and even some clicky articles. It sounds wild enough to share and just believable enough that people start to wonder whether a noisy bathroom break can replace a walk.

In reality, the energy cost of passing gas is tiny. Your abdominal and pelvic floor muscles tense for a moment, pressure changes a little, and then everything settles down again. That brief work might use a fraction of a calorie, roughly in the same ballpark as a single strong cough, so any effect on weight is lost in the background of regular daily burn.

To see how small that is, it helps to place the numbers beside normal movement. Someone who burns around 1,400 to 1,800 calories per day just keeping their body running is already burning close to one calorie each minute while resting. A few short bursts from farting barely move the needle on that total.

Farting Versus Everyday Calorie Burn

Here is a rough comparison so you can see how gas release stacks up next to ordinary actions. Values are rounded from basal metabolic rate ranges and calorie charts that draw on Harvard Health figures for everyday activity.

Action Energy In 10 Seconds Energy In 1 Minute
Quiet resting About 0.2 cal About 1–1.5 cal
Slow walk on level ground About 0.5–0.8 cal About 3–5 cal
Climbing a short flight of stairs About 1–2 cal About 6–10 cal
Single quick fart Well under 0.5 cal Still under 1 cal

This table is not a lab measurement of any one person. It simply shows the scale of things. Even if you pass gas twenty times in a day, the total energy cost stays tiny compared with the hundreds or thousands of calories you burn just sitting, standing, walking, and sleeping.

Once you have a sense of your own daily calorie intake, it becomes clear that gas release is a rounding error next to meals, snacks, and planned exercise.

Where The 67 Calorie Fart Myth Came From

The claim that every fart burns 67 calories seems to trace back to an old viral post that mixed a nugget of physiology with a wild leap in math. The argument goes like this: squeezing your glutes and core uses energy, muscle work burns calories, so an intense clench must be a tiny workout.

Writers picked up that idea and ran with it, turning it into a fake weight loss hack. Some posts even state that farting around fifty times per day would burn more than three thousand calories in a week and strip off half a kilogram of fat without any extra movement. It sounds cheeky and fun, which is why the story keeps spreading.

Health writers now treat that claim as a textbook myth. Articles that review gas, digestion, and energy balance point out that there is no research showing anything close to a 67 calorie burn from a single gas release, and that any tiny muscle effort is swallowed by normal daily metabolic noise.

How Your Body Actually Burns Calories

To see why farting does so little, it helps to step back and see the bigger picture of how your body spends energy across a full day.

Basal Metabolic Rate And Resting Burn

Your basal metabolic rate is the number of calories your body spends just to stay alive. That includes keeping your brain active, your heart pumping, your lungs moving, and your cells warm enough to function. Health resources place this resting burn anywhere from about 1,200 to well over 2,000 calories per day for many adults, depending on size, age, sex, and muscle mass.

Cleveland Clinic and other major centers describe basal metabolic rate as the largest share of daily energy spend, often more than half of the total for the day. Even when you lie still, chemical reactions in every tissue chew through calories at a steady pace.

This background burn already includes the basic work of digestion and bowel movement. Passing gas is simply one tiny moment inside that bigger process.

Movement, Posture, And Small Actions

On top of resting burn, you spend calories on things like walking to the kitchen, standing in line, carrying laundry, typing on a laptop, or riding a bike. Activity charts that use Harvard Health data show that even light movement can double or triple the calories you burn compared with resting in a chair.

That means a brisk ten minute walk might burn thirty to seventy calories, while a half hour of steady cycling can burn several hundred, depending on speed and body size. These activities also build and maintain muscle, which nudges resting burn higher over time.

Short, sharp actions such as a cough, sneeze, or fart do recruit muscles, but they happen so quickly that the total energy cost stays tiny. A gas release may need a split second of work from the diaphragm, abdominal wall, and sphincter muscles, then those muscles switch back to their usual tone.

Digestion, Gas, And Why You Fart

Farting itself comes from gas produced during digestion or swallowed air that travels through the gut. The mix often includes nitrogen, hydrogen, carbon dioxide, methane, and small amounts of sulfur compounds that give gas its smell.

The intestines move this gas along in waves. When enough pressure builds near the rectum, gas leaves the body as flatulence. Medical centers such as the Cleveland Clinic flatulence overview describe this as a normal process that happens between about a dozen and twenty or more times each day for many people.

Guides from sources like the Mayo Clinic intestinal gas causes page list common triggers, such as high fiber foods, lactose, sugar alcohols, and some medical conditions. None of these sources present farting as a calorie burning trick, only as a routine way for the gut to move gas through.

Can Farting Help With Weight Loss?

Short answer: no. Gas release feels active, and a noisy fart might even leave your abs feeling tense for a moment, but the scale cares about total energy balance, not tiny spurts of effort.

Weight change comes down to how many calories you eat and drink across days and weeks compared with how many you spend through resting burn, daily movement, and deliberate exercise. The numbers from those parts of life are large: hundreds of calories from a meal and thousands over a full day.

By contrast, the best guess for the energy cost of a fart sits well below a single calorie. Even if you squeezed as hard as you could and passed gas fifty times per day, the energy spent would still land around the level of a short extra walk, at most. In practice, most gas releases are relaxed and unforced, so they barely add anything.

Relying on farting as a weight loss tactic also misses another angle. Heavy straining during bowel movements and constant tensing of pelvic muscles can be uncomfortable and may aggravate issues such as hemorrhoids or pelvic floor symptoms. Chasing mythical calorie burns in the bathroom simply is not worth the strain.

Healthy Ways To Burn More Calories

While farting will not shrink your waistline, you have many friendly ways to move the needle on daily burn that leave you feeling better overall.

Add Gentle Movement Through The Day

Light activity sprinkled through the day stacks up. Short walks during breaks, pacing during phone calls, parking a little farther from the store entrance, or standing while scrolling all add minutes where muscles stay active.

For many people, a daily step target works as a simple anchor. Aiming for a number that feels realistic, then slowly raising it, can tilt daily energy balance in the right direction without a rigid gym schedule.

Include Intentional Exercise Sessions

Brisk walks, bike rides, dance classes, or home workout videos raise heart rate and breathing for longer stretches. A twenty to thirty minute session can burn a few hundred calories, far beyond anything a bathroom break could match.

Strength training with body weight, bands, or weights adds another layer by building muscle. More lean tissue means a slightly higher resting burn, which keeps paying off even when you lounge on the couch later.

If you like a clear starting point, a basic routine with two or three short strength sessions and several moderate walks per week gives your metabolism a solid nudge without turning life upside down.

Match Food Intake To Your Energy Use

Calorie burn is only one side of the equation. Paying attention to portions, drink choices, and snack habits also shapes where your weight heads over time. Many people find that adjusting liquid calories, such as sweetened coffee drinks or soda, has a big effect without huge changes at meals.

Higher fiber meals with protein and healthy fats can keep you satisfied longer, which makes it easier to stay within a calorie range that fits your goals while still feeling fueled for daily movement.

Sample Daily Energy Picture

To tie all of this together, here is a simple sketch of how calories might add up across a day for one person. The exact numbers change with body size, age, and routine, but the pattern stays similar for many adults.

Part Of Day Main Activity Estimated Calories Burned
Sleeping and quiet resting Eight hours in bed plus light lounging 600–800 cal
Work and errands Sitting, standing, short walks, light chores 500–900 cal
Intentional exercise Thirty minutes brisk walking or cycling 150–300 cal
Gas release across the day Fifteen to twenty quick farts Less than 10 cal total

Again, the gas row mainly shows scale. Even in a day packed with burps and farts, the calories spent on those tiny muscle squeezes fade into the background next to sleep, movement, and planned workouts.

When Gas And Bloating Need Attention

Normal gas comes and goes without much drama. You might feel a brief cramp, pass gas, and move on. Still, some patterns around farting and bloating hint that a checkup with a clinician would be a wise move.

Red flags include gas that comes with ongoing abdominal pain, sudden changes in bowel habits, blood in stool, unplanned weight loss, or frequent diarrhea or constipation. Strong, persistent odor paired with those symptoms can also point toward a deeper issue than simple diet changes.

Medical pages from large centers such as Cleveland Clinic and Mayo Clinic urge people to seek help when gas joins a cluster of other digestive complaints or when it interferes with sleep, work, or daily life. A professional can sort out whether the culprit is diet, medication, infection, intolerance, or another condition that deserves targeted care.

If you are simply gassy but otherwise feel fine, simple changes like slowing down while you eat, cutting back on soda or sugar alcohols, and tracking which foods leave you bloated may bring relief without any need for extreme steps.
