What are the risks associated with a ketogenic diet?

Question

Hello doctor,

I have been reading a lot about the ketogenic diet and its benefits for weight loss, but I am a bit confused about some aspects. I understand that it involves putting the body into a state of ketosis by drastically reducing carbohydrate intake. How exactly does ketosis work in terms of weight loss and energy levels? I have also heard claims that it can affect cellular health and even slow down aging. Can you shed some light on these claims? Are there specific benefits or risks associated with following a ketogenic diet long-term? Also, how does reducing carbohydrates impact overall health? I am interested in your perspective on whether it is a good idea to follow this diet, especially for someone looking to lose weight and improve overall health.

Please guide me.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

Carbohydrates are considered essential nutrients for the body to function properly by several global health organizations, including the World Health Organization (WHO). Their primary role is to provide energy to all cells in the body. In the absence of carbohydrate intake, the body will use an alternative fuel source called ketones.

As your body breaks down fat, it produces a compound called ketones. The ketones, or ketone bodies, become your body and brain's main source of energy. The fat your body uses to create ketones may come from your diet (nutritional ketosis), or it may come from your body's fat stores. If you limit carbohydrates in the long term, it may cause you to have too little of some vitamins or minerals and to experience digestive issues. Carbohydrates often get a bad reputation due to the association of their excessive consumption with weight gain, obesity, metabolic syndrome, and diabetes. This phenomenon, which some researchers call “carbotoxicity,” promotes the idea that the excessive consumption of all types of carbohydrates favors the development of chronic diseases.

Adopting a high-protein diet can be an effective strategy for fat loss, while avoiding certain carbohydrates that are often considered unhealthy due to their low nutritional value, such as:

Refined carbohydrates, such as polished rice and flour.
Sugar-sweetened beverages, like sodas and juices.
Highly processed snacks, including cookies and pastries.

I hope this information helps you, and please reach out if you have any doubts.

Thank you.
