Buteyko Breathing, Metabolism and Obesity
Let me start with something most weight-loss conversations completely overlook: your metabolism is not just about calories, willpower, or even exercise. It’s about how you breathe.
Yes, breathe.
For years, I’ve worked with people who eat well, exercise religiously, and follow every health tip they can find — yet they gain weight, feel sluggish, and struggle with cravings. What they rarely consider is that the unconscious act of over-breathing could be what’s slowing them down.
What Is Over-Breathing?
Over-breathing is not just gasping or panting — it includes the kind of breathing most of us do daily without realizing it:
- Mouth breathing
- Audible breathing
- Frequent sighing or yawning
- Noticeably inhaling through the chest
- Shoulders moving up when inhaling
Most importantly, over-breathing occurs when the level of carbon dioxide (CO₂) in the lungs is too low. The body tries to breathe more to compensate, but this only depletes CO₂ further.
A low level of CO₂ is typical for modern people due to stress, poor posture, over-eating, unbalanced exercising, and — most importantly — improper breathing habits.
To find out whether your CO₂ level is below the norm, which means you over-breathe, you can measure your Control Pause or Positive Maximum Pause — a simple breath-hold test. Dr. Buteyko called CO₂ levels in the lungs, indicated by this test, “the most important regulator of all functions of the body.”
Over-Breathing: The Hidden Saboteur of Weight Loss
Dr. Konstantin Buteyko once conducted an experiment with a group of people — most of them overweight and all with high cholesterol. He asked them to stay on their usual diets, even eat more fatty foods, but to do several sessions of Buteyko breathing exercises each day. After just a week, their cholesterol levels dropped, and many had lost some weight.
How is this possible?
Because breathing less allows your body to rebuild CO₂ levels, which is essential for oxygen delivery, nutrient absorption, and metabolic activity.
Why Breathing Excessively Slows Down Your Metabolism
We’re taught to believe that more breathing equals more oxygen, which equals more energy. But that’s not how the body works.
According to the Bohr Effect, when CO₂ levels drop, hemoglobin holds onto oxygen instead of releasing it into the cells. So even though you’re inhaling plenty of air, your cells are still starved of oxygen.
When cells don’t receive oxygen, your metabolism slows down. Digestion becomes inefficient. Nutrient absorption suffers. You may feel hungry, fatigued, and bloated — even after eating a large meal.
How Higher CO₂ Activates Your Metabolism
When you breathe less and more gently, especially through your nose, CO₂ levels in your lungs and blood increase. This has several powerful effects:
- Improved Oxygen Delivery
CO₂ allows hemoglobin to release oxygen into your tissues. Without it, oxygen stays trapped in your blood. - More Cellular Energy (ATP)
With better oxygen delivery, mitochondria produce more ATP — the energy currency of your body. More ATP = more metabolic activity. - Enhanced Blood Flow and Enzyme Activity
CO₂ dilates blood vessels and activates key metabolic enzymes. This boosts digestion, hormone balance, and repair mechanisms. - Reduced Hunger and More Satisfaction
Once your cells are nourished, your brain stops sending panic signals for food. You feel full and calm with less.
I call this natural shift the “Air Diet.” It’s not about food restriction. It’s about reducing air volume to rebuild CO₂ and ignite your metabolism.
Why the “Eat Less, Move More” Advice Often Fails
I’ve worked with many active people — trainers, dancers, athletes — who still struggled with their weight despite strict discipline. The missing link? They were overbreathing most of the day, especially during exercise.
Their workouts were intense. Their meals were controlled. But their CO₂ levels were low.
Once they learned to breathe gently and nasally, everything changed: deeper sleep, fewer cravings, better digestion, and natural, sustained weight loss.
“Eat less” doesn’t work unless it helps retain or raise CO₂. In fact, chronic under-eating can lower CO₂ by increasing stress and disrupting digestion.
“Move more” is only helpful when movement results in a CO₂ increase. Light to moderate nasal-breathing movement supports metabolism. However, intense mouth-breathing workouts often lead to the dumping of CO₂ and backfire, resulting in fatigue, overeating, and weight gain.
The Buteyko Approach: Eating, Breathing, and Metabolism
1. Eating:
A. Let Your Breath Be Your Guide
At the Buteyko Breathing Center, I teach students to measure their Control or Positive Maximum Pause (CP or PMP) before and after meals. If your CP drops significantly, the food wasn’t right for your current condition, whether due to stress, quantity, or content.
Dr. Buteyko taught that any food or drink that lowers your CP by more than three seconds is not suitable for your system right now. The right food is the one that allows you to breathe calmly and silently, even after your meal.
Sometimes people blame food for fatigue and bloating, when in fact it’s the over-breathing that occurs during eating, especially when talking, that causes their CO₂ levels to drop.
There is no universal diet. The best diet is the one that keeps your breathing nasal, silent, and light — and it remains so after meals. That’s how your body tells you what supports your metabolism.

B. Eating Less Is a Natural Outcome of Breathing Less
As CO₂ increases, people often lose interest in processed and sugary foods. Cravings vanish. They begin enjoying simpler, cleaner meals—like soups, fresh vegetables and fruits, or lightly cooked grains.
One of the most beautiful and consistent effects I see in students is that they eat less, but not because they’re trying.
When oxygen delivery and nutrient absorption improve, the body is satisfied with less. Hunger signals return to their natural rhythm. There’s no need to eat for energy, because the body already has it.
I remember one of my clients, an acupuncturist from New York, who lost about 30 pounds during the course. Not through restriction, but because he naturally stopped feeling hungry at night and chose to skip dinner. His body simply didn’t need more.
This is how real balance feels. It’s not about denying yourself. It’s about finally being nourished.
2. Exercise:
A. Combine It With Healthy Breathing
Modern fitness often glorifies high intensity, sweating, and heavy mouth-breathing. But this often leads to CO₂ loss, which slows your metabolism.
At the Buteyko Breathing Center, I encourage students to track their CP after workouts. Many are shocked to find that their exercise lowers CO₂.
We then shift toward nasal, silent breathing during physical activity and introduce breathing reduction techniques. This helps increase CO₂ post-workout, boosting metabolism rather than suppressing it.
You don’t have to stop exercising. You just need to learn how to do it in a way that supports your breath and increases your CO₂ production.

B. Movement Begins With Breath
Many people living with obesity struggle to move their bodies. Physical discomfort, pain, joint issues, or sheer fatigue can make even walking feel overwhelming. And yet, almost every conventional weight-loss plan starts with movement — as if everyone can just “get up and go.”
This is one of the reasons I love the Buteyko Method so much. It offers a gentle, effective entry point — even for those who cannot move freely.
When I work with clients who have limited mobility, we begin with breathing exercises in a seated position. No pressure, no strain. Just quiet, nasal breathing and reduced air intake. As their breathing normalizes, their CO₂ levels begin to rise. This activates their metabolism and gradually boosts their energy levels.
And something remarkable happens: as energy builds from within, movement becomes possible. First, small, gentle motions. Then, walking. Eventually, many feel ready for more structured physical activity (always accompanied by healthy breathing).
The Buteyko approach doesn’t demand movement as a starting point. It makes movement possible. That’s what makes it so unique and so kind.
A Vicious Cycle: Extra Weight and CO₂ Loss
There’s also a vicious cycle at play that many people don’t realize: every extra pound on your body increases your breathing volume. That means more air, more effort… and unfortunately, more CO₂ loss. The heavier you are, the more likely you are to over-breathe, even when you’re at rest. And the more you over-breathe, the harder it becomes to lose weight.
When people lose weight, their breathing naturally becomes lighter and quieter. This allows the body to maintain higher CO₂ levels more easily, which supports oxygen delivery, improves metabolism, and reduces cravings. But here’s the problem: how do you lose weight when the extra weight itself causes you to over-breathe and lose CO₂?
This is where Buteyko Breathing exercises provide a powerful solution. By practicing breathing reduction, you can start raising your CO₂ levels before weight loss happens. These exercises give your body the oxygen and metabolic activation it needs to begin releasing excess weight, helping you escape this cycle, gently and naturally.
Healing, Not Fighting
Many people carry guilt about their weight. They believe they lack discipline, or that something is wrong with them. But I want to say this:
It’s not about willpower. It’s about biochemistry.
Over-breathing causes CO₂ loss. Blood vessels constrict. Digestion weakens. The thyroid slows down. Your body senses danger… and stores fat.
With breathing normalization, your body shifts from protection mode to healing mode. Weight loss becomes a side effect of restored balance.
How to Begin Losing Weight Naturally With Buteyko
If you’ve tried everything and still feel stuck, maybe it’s time to stop struggling and start listening — to your breath.
Step 1: Become Aware
Notice how you breathe throughout the day. Are you using your mouth? Is your breath audible? Do your shoulders rise? These are signs of over-breathing.
Step 2: Begin Breathing Less
You can start with the Buteyko Breathing Step-by-Step video course. If you experience difficulties in applying the method, I offer private sessions.
The most effective path is the Buteyko Breathing Normalization Training, which starts with a free preliminary Consultation. This course is a 2–4 month program that re-trains automatic breathing patterns, allowing the establishment of healthy nasal breathing and reduced air intake 24/7. During this program, I work with my clients one-on-one, fully customizing the Buteyko method to their individual situation and lifestyle. Together, we measure the effect of every activity on their CO₂ levels and consequently their metabolism.
In this process, overweight clients often lose weight naturally, and underweight clients often gain it. Why? Because breathing normalization leads to metabolic normalization.
My Own Story
Before I discovered the Buteyko Method nearly 20 years ago, I struggled with cravings, sluggish digestion, and stubborn weight. I wasn’t significantly overweight; however, losing even a few pounds required pills to suppress my appetite. I was always snacking or drinking tea to stay energized. If I skipped a meal, I felt shaky, tired, and irritable.
Periodically, I experienced bloating and constipation.
After learning and applying Dr. Buteyko’s discoveries, everything changed. Now, most of the time, I eat twice a day, rarely snack, and feel fully nourished. No pills, no rules. Just a naturally healthier way of eating.
The Buteyko Method is not about eating less to suffer. It’s about breathing less to heal.
And when healing happens, weight loss follows — not through struggle, but through inner peace and balance.
