The benefits of the ketogenic diet: a return to our natural state

The keto or ketogenic diet has become popular in recent years, but its roots go back to the very origins of humanity. In this article we explore the basics of this way of eating, which aims to take us back to ketosis, a natural state we are born in and which prevailed for millions of years.

Ketosis as our natural state

When blood glucose is scarce, the liver produces ketones from the fat we eat or from our own reserves. This state, known as ketosis, is the natural state of human beings. In fact, we're born in ketosis, but over time we've lost this ability because of the refined carbohydrates in our daily diet.

Keto-adaptation and the loss of our natural condition

For millions of years our genes have adapted to using ketones as their main source of energy, which generates less oxidative stress than using glucose. Keto-adaptation has become essential because we've lost the ability to use our natural state efficiently, leaving us with constantly high blood sugar and unable to produce ketones.

The impact on our health: less glucose, less oxidative stress

Tribes that still live in the wild, such as the Inuit, Hadza and Maasai, keep blood glucose levels between 40 and 60 mg/dL. By contrast, most of us struggle with higher levels because of a diet rich in refined carbohydrates, which contributes to a pro-oxidative and pro-carcinogenic state. This contrast underlines how important diet is to our physiology. Find out how our approach to psychoneuroimmunology can help improve your wellbeing by adjusting your diet and lifestyle.

Ketones and cancer: an approach under study

Using ketones as an energy source has notable benefits, especially in the fight against cancer. Cancer cells struggle to survive in ketosis because they rely mainly on glucose. Lower glucose levels may be key to preventing and treating disease.

The challenges and rewards of keto-adaptation

Switching to a ketogenic diet means moving away from dependence on carbohydrates and eating less often. The transition can bring symptoms of low energy, but once keto-adapted you'll notice a significant boost in energy, even while fasting.

The future of the ketogenic diet: more than a fad

Although the ketogenic diet may look like a current trend, its health benefits were already recognised in 1920. This way of eating, which was the norm for much of human evolution, offers a chance to restore our natural state and enjoy a healthier, more energetic life.
