Keto Diet for Heart Health: Is It Safe and Effective?

A review published in the March 2024 issue of Current Problems in Cardiology raises concerns about the suitability of the ketogenic (keto) diet for everyone, especially those with heart disease. While short-term studies have shown that the diet can reduce fat mass and weight, long-term benefits remain uncertain. Additionally, keto diets can lead to lower triglyceride levels but higher levels of LDL cholesterol, which is associated with an increased risk of heart disease.

The extreme carbohydrate restrictions of the keto diet may result in a limited intake of vegetables and fruits while increasing consumption of leafy greens. However, leafy greens are high in vitamin K, which could interfere with blood-thinning medications such as warfarin used by some heart patients. Furthermore, individuals taking SGLT-2 inhibitors for diabetes and heart failure may find these medications incompatible with a keto diet due to potential side effects.

Therefore, individuals with heart disease must carefully consider the potential risks and benefits of the keto diet before incorporating it into their lifestyle. It is recommended to consult with a healthcare professional for personalized advice if you have concerns about your diet and heart health.
