An investigation conducted in Canada revealed a possible link between the keto diet and the risk of cardiovascular events.

The study was led by Iulia Iatan from the Prevention Clinic of the Healthy Heart Program of St. Paul and Center for Heart and Lung Innovation at the University of British Columbia in Vancouver, and was presented at the annual scientific meeting of the American College of Cardiology along with the World Congress of Cardiology.

It states in detail that regular consumption of this type of diet has been found to result in higher levels of bad cholesterol (LDL). Among the identified risks are blockage of arteries, heart attack and even stroke.

How do I know if the ketogenic diet is for me?

“The justification for our study was based on the fact that in our cardiovascular disease prevention clinic we saw patients with severe hypercholesterolemia who followed this diet,” Iatan said in a presentation he collected CNN.

The researchers established a low-carbohydrate, high-fat diet consisting of no more than 25% of total daily calories from carbohydrates and no more than 45% of total daily calories from fat.

In total, the diets of 305 people were compared with another 1,200 people who followed a standard diet.

“Before starting this diet, they should consult a doctor. During the diet, it is recommended to monitor cholesterol levels and try to address other risk factors for heart disease or stroke, such as diabetes, high blood pressure, physical inactivity and smoking,” the statement added.

Iatan clarifies that they were only able to establish a connection between the two events, not a causal connection.
