Diet: Ketogenic diet a risk for the heart?


In their evaluation of the available studies on ketogenic diets and intermittent fasting, the researchers conclude that ketogenic diets and intermittent fasting can help people lose weight in the short term, positively influence blood pressure, counteract diabetes and also contribute to cardiovascular health.

In a comprehensive evaluation of previous studies on ketogenic diets and intermittent fasting, numerous advantages for both forms of diet were confirmed. However, a ketogenic diet could also increase the risk of cardiovascular disease, warn the researchers from National Jewish Health in a press release on the study results. The study was published in the American Journal of Medicine.

The ketogenic diet is in vogue and many use it to lose weight. Promising health benefits are also associated with the popular diet. For example, the ketogenic diet is said to counteract diabetes and high blood pressure and to have a positive influence on fat metabolism. However, the risk of heart problems could also increase.

With the ketogenous nutrition however the consumption of saturated fats and animal products such as red meat is permitted, of which it is well-known that they increase the risk for cardiovascular diseases, kidney diseases and cancer, explain the researchers. Thus the ketogenic diet could also lead to an increased intake of foods that are known to be harmful.

Advantages of ketogenic nutrition and chamfered

Although the ketogenic diet could be an approach to the prevention of cardiovascular diseases if planned carefully and strictly adhered to, in practice this dietary approach is probably not suitable for most people, the researchers warn.

The researchers also have concerns about the type and amount of fat ingested by people on a ketogenic diet. While studies strictly control the type of fat and food consumed by participants, in practice many people on a ketogenic diet consume high levels of unhealthy saturated fats. And saturated fatty acids are associated with an increased risk of heart disease and high lipid levels in the blood, the researchers emphasize.

In addition, there are also individual indications that a ketogenic diet over a longer period of time can lead to stiffening of the arteries and that the risk of premature death increases, explains the research team.

Ketogenic nutrition puts the body into ketosis, a metabolic state in which access to glucose is reduced and which is instead mainly fed by fat. The study analysis shows that a ketogenic diet usually results in weight loss at first, but the weight loss is often not sustainable. It is also unclear whether the weight loss is caused by ketosis or simply by calorie restriction, the team explains.

Furthermore, it is particularly important for people with diabetes, for example, to consult a doctor before attempting intermittent fasting in order to clarify how they can control their disease and the risk of hypoglycemia. Because the latter threatens if regular meals are missed.

A majority of the current realizations over the potential use of intermittent chamfered originate besides from animal experiments, in which an increased life expectancy, weight acceptance, lowering of the blood pressure, an improved glucose tolerance and better Lipidwerte were observed, describe the team. To what extent these are transferable to humans, remains open.

The researchers report likewise on potential health advantages of intermittent chamfering, are however also here concerned about possible pitfalls. They fear that the hunger with chamfered could cause many humans to overeat at meals or make unhealthy food decisions, which have negative effects on their kardiovaskuläre health.
