A new study has linked a “keto-like” diet to an increased risk of heart disease. The study, conducted by Harvard researchers and published in the Journal of the American College of Cardiology, analyzed data from over 220,000 participants over a 20-year period.

The study found that those who followed a low-carb, high-fat diet similar to the popular ketogenic diet were more likely to develop heart disease than those who followed a diet that included more whole grains, fruits, and vegetables.

Lead author of the study, Dr. Frank Hu, explained that the “keto-like” diet may increase the risk of heart disease due to its high fat content.

“Diets that are very high in fat can increase levels of LDL cholesterol, also known as ‘bad’ cholesterol, which can contribute to the development of heart disease,” Dr. Hu said.

The study has raised concerns among proponents of the keto diet, who argue that the diet can be sustainable and healthy when followed correctly.

However, Dr. Hu emphasized the importance of a balanced diet that includes a variety of healthy foods.

“It’s important to focus on whole foods and a balanced diet that includes healthy fats, whole grains, fruits, and vegetables,” Dr. Hu said.

The study is expected to spark further debate about the risks and benefits of the popular keto diet, and may prompt some individuals to re-evaluate their dietary choices.
