The Lungs as Principal Excretory Organs for Weight Loss

The lungs are, in fact, the principal excretory organs that are responsible for weight loss:

When does fat become lost?

During the process of weight loss, your body will convert fat cells into carbon dioxide and water. Because you exhale the carbon dioxide, the water is absorbed into your circulation and continues to do so until it is expelled via urine or perspiration.

What is the amount of fat that is gone via the lungs?

In a study that was published in The BMJ, it was shown that when 10 kilograms of fat are oxidized, 8.4 kg of the fat are transformed into carbon dioxide and then expelled via the lungs.

Find out how to lose weight.

To lose weight, you need to balance what you consume against what you burn off and exhale. You can accomplish this by:

✓ Consuming fewer calories

✓ Moving more

✓ Engaging in physical activity of a moderate level, such as jogging The practice of engaging in exercises that build muscles, such as weightlifting or Pilates.

✓ Doing breathing exercises

According to experts from the University of New South Wales in Australia, when weight is shed, the bulk of it is breathed out as carbon dioxide. Their study is published in the Christmas edition of The BMJ.

Prof. Andrew Brown and Ruben Meerman revealed widespread confusion about how weight is shed, finding doctors, nutritionists, and personal trainers all equally guilty of not knowing. Most thought that fat is transformed to energy or heat.

Excess dietary carbs and protein are transformed into a kind of fat called triglyceride. When individuals seek to lose weight, they are striving to metabolize these triglycerides while keeping their fat-free mass intact, say the authors.

Triglycerides are formed of three sorts of atom: carbon, hydrogen, and oxygen. Triglyceride molecules can be broken down only by liberating these atoms via a process called oxidation.

On average, a person weighing 70 kg will exhale roughly 200 cc of CO2 in 12 breaths each minute. The authors estimated that each breath comprises 33 mg of CO2, with 8.9 mg composed of carbon. A total of 17,280 breaths throughout the day will get rid of at least 200 g of carbon, with nearly a third of this weight loss happening during 8 hours of sleep.

The carbon that is lost during exhalation is only restored by the ingestion of food and beverages such as fruit juice, milk, and soft drinks.“ Keeping the weight off just demands that you put less back in by eating than you’ve expelled by breathing.

Eat less, exercise more.

The quantity of carbon that is lost may be increased by activity. By exchanging 1 hour of rest for 1 hour of moderate activity such as jogging, the metabolic rate is enhanced sevenfold, eliminating an extra 40 g of carbon from the body, raising the daily total by about 20% to 240 g.

However, this may readily be negated by poor food. A single 100 g muffin, for example, supplies roughly 20% of an average person’s entire daily energy intake.
