New study links ‘keto-like’ diets with cardiovascular issues
LOUISVILLE, Ky. (WAVE) - Doctors are warning people to be careful before starting a pre-summer diet.
A new study shows “keto-like” diets may be linked to a heightened risk for cardiovascular events.
The results of the study were presented at the American College of Cardiology’s 2023 Annual Scientific Session & Expo Together With World Congress of Cardiology.
Norton Healthcare shared some of the findings from that study.
Researchers analyzed and compared the diets of 305 people eating a low-carb, high-fat (LCHF) diet, which is considered keto-like, with roughly 1,200 people eating a standard diet.
The researchers found people who participated in an LCHF diet had significantly higher levels of both low-density lipoprotein (LDL, or “bad”) cholesterol and apolipoprotein B (apoB), the protein component that sits on LDL.
The study also showed people on keto-like diets had more than two times higher risk for major cardiovascular events, such as arterial blockages requiring stents, heart attacks, strokes and peripheral arterial disease (narrowing/blockage of vessels that carry blood from the heart to the legs).
Dr. Kelley McIntyre, an internal medicine physician with Norton Community Medical Associates – Audubon, said some people might be at heightened risk for complications.
“Because if a patient already has underlying heart disease or issues like that or elevated cholesterol, it could possibly raise those, especially if you’re doing a really high animal fat, saturated fat diet,” McIntyre said.
McIntyre said people should talk to their doctors before making any major diet changes. Doctors can also recommend alternative weight-loss techniques.
