A New 2025 Study Confirmed the Impact of the Ketogenic Diet on Reducing Inflammation and Improving Metabolism

A new study conducted in 2025 confirmed the positive impact of the ketogenic diet on metabolism and inflammatory processes in the body. The results showed that this diet not only contributes to weight loss but also has a pronounced anti-inflammatory effect in patients with metabolic syndrome.

The ketogenic diet is characterized by a sharp restriction of carbohydrates in the diet (up to 5–10% of daily intake), while a significant portion of energy comes from fats – up to 70–75%. This dietary regimen shifts the body into a state of ketosis – a metabolic switch where ketone bodies produced by the liver are used as the primary energy source instead of glucose.

The 2025 study noted that most patients experienced improvements in metabolic status: blood sugar levels decreased, insulin sensitivity increased, and pro-inflammatory markers significantly reduced. This confirms the effectiveness of the ketogenic diet in a comprehensive approach to the treatment and prevention of diseases related to metabolic disorders.

Mechanisms of Action of the Ketogenic Diet

• Reducing carbohydrates leads to a decrease in blood glucose levels and activation of ketone body production.
• Ketone bodies replace glucose as an energy source for the brain and other organs, thereby reducing oxidative stress and inflammation.
• Improved insulin response contributes to normalizing metabolism and reducing obesity.

The ketogenic diet has previously been used in the treatment of neurological diseases, but the new study opens up possibilities for its use in combating metabolic syndrome and inflammatory processes that underlie many chronic diseases.

Doctors note that in the first few days of following the diet, a person may experience certain adaptation symptoms, such as mild weakness and changes in sleep, but over time, the body adjusts to the new metabolic regime, and the overall condition stabilizes.

This diet requires adherence to strict rules regarding the ratio of macronutrients and the exclusion of high-carbohydrate foods. Including a large amount of fats (both saturated and healthy unsaturated) as well as moderate protein intake are key conditions for successfully achieving ketosis and maintaining health.
