- Researchers investigated whether high-fat, low-carbohydrate, keto-like diets increase cardiovascular risk.
- Keto-like diets were linked to twice as many cardiovascular events as standard diets.
- Further research is needed to confirm the results.
The ketogenic or “keto” diet
Some
Case studies, however, suggest that the keto diet may exacerbate or cause high cholesterol.
Further studies investigating how keto diets affect cardiovascular health could inform dietary options for individuals with different health profiles.
Recently, a study led by Dr. Iulia Iatan, attending physician-scientist at the Healthy Heart Program Prevention Clinic, St. Paul’s Hospital and University of British Columbia’s Centre for Heart Lung Innovation in Vancouver, Canada, assessed how low-carbohydrate, high-fat (LCHF) diets, similar to keto diets, may affect cardiovascular risk.
The research found that a LCHF diet almost doubled the risk of cardiovascular events when compared to a standard diet.
The study was presented at a conference held jointly by the American College of Cardiology and the World Heart Federation — the ACC Annual Scientific Session together with the World Congress of Cardiology.
For the study, the researchers analyzed information collected by the UK Biobank for individuals with data on serum lipids, metabolomic markers, and dietary patterns.
All participants had recorded their diet in a 24-hour food survey. Among them, 305 met the criteria for an LCHF diet, defined as consuming less than 25% of daily calories from carbohydrates and more than 45% from fat.
