Keto Warning: How a Popular Diet Could Be Harming Your Heart

A new study has questioned the safety of one of the most popular diets of our time, the ketogenic diet. This low-carb, high-fat eating pattern has gained popularity among those looking to lose weight quickly or boost their energy levels. But scientists have found that it can seriously damage the cardiovascular system.

According to the findings presented at the American College of Cardiology’s annual scientific session, people who follow a keto-like diet (high in fat and low in carbohydrates) have twice the risk of developing cardiovascular disease. These complications include clogged arteries, chest pain (angina), heart attacks and strokes.

The study involved more than 300 people who reported eating a keto-like diet — low in carbohydrates (less than 25% of total energy intake) and high in fat (more than 45%). The researchers compared the results with a control group of more than 1,200 participants. The results showed that the former group had significantly higher levels of “bad” cholesterol (LDL) — a known risk factor for heart disease.

The researchers emphasize that a high-fat diet can contribute to an increase in low-density lipoproteins, which are deposited on the walls of arteries, leading to their narrowing and an increased risk of blood clots. So while the keto diet may be effective for short-term weight loss, its long-term adherence carries serious risks for heart health.

Additionally, experts note that most people on these diets consume a lot of saturated fat (from meat, butter, coconut oil, for example) while avoiding healthy sources of carbohydrates, such as vegetables, fruits, and whole grains. This can lead to a deficiency in fiber and other important nutrients needed for heart health. Despite the popularity of keto among fitness bloggers and influencers, doctors advise caution. If you are considering changing your diet, it is best to consult a qualified dietitian or doctor. A healthy diet should not only help control weight, but also ensure the long-term functioning of all body systems — especially the cardiovascular system.
