The ketogenic diet , also known as the "keto" diet, has become fashionable again, and it is not surprising, since it has been found to be a useful dietary strategy to lose weight in many people, but ... Is it dangerous? Before continuing I would like to clarify that the ketogenic diet is not a "detox" diet , confusion is quite common, and since we are in a time very prone to "experiments". What is a ketogenic diet? Therefore the next question seems obvious: What are ketone bodies? These are molecules that are formed after using fats for energy, and that for the most part we can use again as an energy source. Because in nature carbohydrates , also called carbohydrates, are not as abundant as in industrial society: there was no bread, no pasta, no soft drinks ... it is believed that it was relatively common for us to be in ketosis. At least during periods of fruit shortage, such as winter. In fact, our species has been a hunter and gatherer for millennia, therefore our sources of carbohydrates were the leaves of vegetables, their fruits, some roots and tubers. On the other hand, in a ketogenic diet to induce the use of fats as the main energy substrate, its intake must be considerably increased, which must account for at least 70% of the energy consumed . When in a conventional diet the fats are around 30 or 35%. What can you eat on a ketogenic diet?In a ketogenic diet we talk about eating carbohydrates and this value depends a lot on the metabolism of each person. Some with higher amounts of carbohydrates are already beginning to use fat as their main source of energy, while others must restrict it more to cause this metabolic change. It is usually recommended that the amount of carbohydrates is less than 100 g per day, although it may have to be much less . I insist that I speak of grams of carbohydrates, not of the food that contains it. For example, if we talk about 100 g of bread, we must know that it contains around 50 g of carbohydrates. Because tubers, cereals and legumes have a high percentage of carbohydrates, they are not included in the ketogenic menus, nor are most fruits, whose carbohydrate percentage can be classified as medium, and even several types of nuts exceed the proportion recommended: pistachios, cashews, peanuts ... Benefits of the ketogenic dietAnother of its benefits is that ketone bodies can be used by the brain as a source of energy , and this is useful in some diseases of the nervous system, such as certain types of epilepsy or dementia.

It is also investigated whether the use of ketone bodies in the brain improves certain cognitive abilities in healthy people, such as attention. For the moment I tell you that some results seem encouraging. Another of its most striking effects is that, in some types of tumors, its follow-up together with the corresponding oncological treatment can contribute to improving the prognosis . This is probably because it reduces inflammation and insulin production, which contribute to tumor progression. Dangers of the ketogenic dietThe main risk of the keto diet is that, like all diets that restrict food, if not followed correctly, it can imply a shortage of micronutrients , but also, the fact that it is high in fat, can lead to other side effects .
