Farting burns an insignificant amount of calories, making it a negligible factor in weight loss or calorie expenditure.
The Science Behind Flatulence and Energy Use
Flatulence, commonly known as farting, is a natural bodily function caused by the release of gas from the digestive system. This gas is produced through the breakdown of food by bacteria in the intestines. While it’s often a source of humor or embarrassment, many wonder if this process actually burns calories or helps with weight loss.
The truth lies in understanding how energy expenditure works within the human body. Calories are units of energy derived from food that fuel bodily functions and physical activity. Energy expenditure is influenced by factors such as basal metabolic rate (BMR), physical movement, digestion, and thermogenesis (heat production). The act of farting itself is simply the release of accumulated intestinal gas and does not require significant muscular effort or metabolic energy.
The muscles involved in farting include the anal sphincter and some abdominal muscles to build pressure for expulsion. However, this muscular activity is minimal compared to other physical actions like walking, running, or even digesting food. Therefore, any calorie burn associated with farting is so small it’s practically unmeasurable.
What Causes Gas Production?
Gas in the digestive tract comes from swallowed air and the fermentation of undigested carbohydrates by gut bacteria. Foods like beans, cabbage, onions, and carbonated drinks are notorious for increasing gas production. When bacteria break down these carbohydrates anaerobically (without oxygen), they produce gases such as hydrogen, methane, and carbon dioxide.
This gas accumulates until pressure builds enough to trigger flatulence. The frequency and volume of farting depend on diet composition, gut microbiota balance, and individual digestive health.
Even though this process involves biochemical reactions inside your gut that consume energy at a cellular level, it’s important to note that these reactions do not translate into significant calorie burning for your body as a whole.
Energy Cost of Flatulence: How Much Does It Really Burn?
If we consider muscle contractions during flatulence as a form of physical activity, it might seem reasonable to assume some calories are burned. But how much?
The anal sphincter muscle is skeletal muscle controlled voluntarily but used involuntarily during flatulence release. The contraction required to hold in or expel gas is extremely brief and light compared to sustained activities like lifting weights or jogging.
Scientific estimations suggest that even intense voluntary contractions of small muscle groups burn only a few calories per minute at best. Since farting lasts just seconds and involves minimal muscle engagement, calorie expenditure from this activity likely falls in fractions of a calorie—far too small to impact overall energy balance.
A rough analogy might be the difference between blinking your eyes versus running a mile. Blinking uses some muscles but doesn’t burn meaningful calories; similarly, farting uses minor muscles briefly without significant energy cost.
Comparing Calorie Burn: Flatulence vs Other Activities
To put things into perspective:
| Activity | Approximate Calories Burned (per minute) | Energy Source |
|---|---|---|
| Farting (flatulence) | ~0.01 calories | Minimal muscle contraction |
| Walking (3 mph) | 3-4 calories | Skeletal muscle movement |
| Digesting food (thermogenesis) | 5-10% of meal calories burned over hours | Metabolic processing |
This table highlights how insignificant calorie burn from farting really is compared to everyday activities like walking or even digesting food.
The Role of Digestion in Calorie Burning
Digestion itself requires energy—known as the thermic effect of food (TEF). TEF accounts for roughly 5-10% of total daily calorie expenditure as your body breaks down macronutrients into usable components.
While gut bacteria produce gas during fermentation—a key step in flatulence—the overall process contributes minimally to TEF-related calorie burn. The biochemical reactions within your intestines consume some energy but nowhere near enough to affect weight loss efforts meaningfully.
In fact, digestion-related energy use dwarfs any tiny expenditure involved in releasing intestinal gas. So if you’re hoping farting will help you shed pounds faster than eating healthy meals or exercising—sorry to burst that bubble!
The Myth That Farting Helps You Lose Weight
There’s an urban myth floating around that “letting it rip” can help you lose weight by burning calories through expelling gas. This idea likely stems from misunderstandings about bodily functions and metabolism.
While releasing gas may give temporary relief from bloating or discomfort caused by trapped intestinal air, it does not equate to burning fat or significant calories. The amount of energy needed for flatulence is negligible compared to what’s required for sustained physical activity or proper diet management.
Weight loss depends on creating a consistent calorie deficit—burning more calories than consumed over time—not on passing gas more frequently!
The Digestive System’s Energy Dynamics Explained
Your digestive system is an intricate network where multiple processes consume energy:
- Mastication: Chewing food requires minor muscular effort.
- Peristalsis: Rhythmic contractions move food along intestines.
- Chemical digestion: Enzymes break down nutrients.
- Nutrient absorption: Transport across intestinal walls.
- Bacterial fermentation: Produces gases and short-chain fatty acids.
Among these steps, bacterial fermentation produces gases responsible for flatulence but also generates compounds beneficial for colon health like short-chain fatty acids that provide some caloric value back to your body.
Despite this complex interplay, only a fraction of total metabolic rate accounts for these processes combined—and even less relates specifically to expelling gas itself.
The Microbiome’s Influence on Gas Production and Energy Use
Your gut microbiome—the trillions of microorganisms inhabiting your intestines—plays a huge role in digestion efficiency and gas production levels. Different bacterial species ferment various substrates differently:
- Bacteroides: Efficient carbohydrate fermenters producing moderate gases.
- Methanogens: Convert hydrogen into methane gas.
- Lactobacilli: Produce lactic acid with less gaseous output.
A balanced microbiome can minimize excessive bloating while maximizing nutrient extraction from food. Though microbial metabolism consumes some energy at microscopic levels, these processes don’t translate into measurable increases in human calorie burn through flatulence.
Modulating your diet can influence microbiota composition—and consequently gas production—but won’t significantly affect overall caloric expenditure via farting alone.
The Physiology Behind Muscle Use During Flatulence
Flatulence involves coordinated muscle actions primarily centered around:
- The internal anal sphincter: Involuntary smooth muscle controlling baseline closure.
- The external anal sphincter: Voluntary skeletal muscle allowing conscious control over release.
- The pelvic floor muscles: Supportive muscles helping maintain continence.
- The abdominal muscles: Sometimes contract slightly to increase intra-abdominal pressure aiding expulsion.
Though these muscles engage briefly during farting episodes, their activation lasts seconds at most with minimal force output relative to other physical exertions like lifting weights or sprinting.
Muscle contractions require ATP (energy currency), but given their short duration and low intensity during flatulence events, total ATP consumption—and thus calories burned—is negligible when summed over time.
A Closer Look at Muscle Fiber Types Involved
The external anal sphincter contains predominantly fast-twitch muscle fibers designed for quick contractions when needed—like holding back sudden urges—but not endurance work that burns many calories over time.
Meanwhile, smooth muscle fibers in the internal sphincter maintain tonic contraction without conscious effort but consume very little energy compared to skeletal muscles because they contract slowly and sustain tension efficiently.
This explains why holding or releasing gas doesn’t significantly tax your muscular system nor contribute meaningfully to total daily caloric expenditure.

Frequently Asked Questions
Does farting make you lose calories?
Farting burns an insignificant amount of calories, so it does not contribute meaningfully to weight loss. The muscular effort involved is minimal compared to other activities like walking or exercising.
How many calories can you burn by farting?
The calories burned during farting are practically unmeasurable. The small muscle contractions involved do not require enough energy to impact overall calorie expenditure.
Can frequent farting increase calorie burn?
Frequent farting does not significantly increase calorie burn. While gas production involves biochemical processes, these do not translate into meaningful energy use for the entire body.
Is there any metabolic benefit from the process of farting?
The metabolic cost of producing and releasing gas is very low. Although gut bacteria break down food and produce gas, this does not result in a notable increase in calorie burning.
Does diet-related flatulence affect calorie loss?
Foods that cause more gas, like beans or cabbage, may increase flatulence but do not lead to increased calorie loss. The energy spent on releasing gas remains negligible regardless of diet.
The Bottom Line – Does Farting Make You Lose Calories?
To wrap it up clearly: no matter how many times you pass gas daily—or how forcefully—you won’t be torching noticeable amounts of calories by doing so. The muscular effort involved is minimal; biochemical processes producing intestinal gases don’t translate into increased whole-body calorie burning; psychological factors influence perception but not metabolic cost; and dietary choices affecting gas production don’t alter fat loss dynamics directly through flatulence either.
If you’re aiming for effective weight management:
- Create consistent calorie deficits via proper nutrition;
- Add regular physical activity;
- Aim for balanced gut health;
- Avoid relying on myths like “fart burning” for weight loss.
