Lungs

The lungs are the respiratory organs responsible for the intake of oxygen into the blood and the removal of carbon dioxide from the body.

Ketosis requires more oxygen to burn fats.

While direct studies confirming the improvement of lung function solely due to the keto diet are limited, there is indirect evidence that this type of diet may have a positive impact on the respiratory system.

Here are a few possible mechanisms:

• Inflammation. The ketogenic diet may reduce systemic inflammation. Since inflammation plays a role in many respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD), the keto diet may help improve lung symptoms and function.
• Oxidative stress. High levels of ketones may reduce oxidative stress, which positively affects lung health and may prevent tissue damage.
• Weight management. The keto diet often leads to weight loss, which can be particularly beneficial for people with obesity, suffering from sleep apnea or other respiratory problems related to excess weight.
• Insulin resistance. Improving insulin sensitivity through the ketogenic diet may help reduce chronic conditions that can impact the respiratory system.

Impact of Diet on the Respiratory System

Nutrients in foods contribute to maintaining lung health.

For example, nuts are rich in magnesium, which helps widen the bronchi and improve breathing.

Fish containing Omega-3 fatty acids helps reduce inflammation in the lungs.
