Which diet is better for your heart—Mediterranean or keto? Discover how each impacts blood pressure, weight, and long-term health based on new research.
🥑 Keto vs. Mediterranean: Which Diet Lowers Blood Pressure More Effectively?
Published: June 1, 2025
🌟 Introduction: The Battle of the Diets
High blood pressure, or hypertension, affects millions worldwide and is a leading risk factor for heart disease and stroke. While medications are available, dietary interventions remain a cornerstone of blood pressure management. Two popular diets—the Mediterranean and ketogenic (keto) diets—have been studied for their potential benefits in lowering blood pressure. But which one is more effective?Medical News Today
🥗 The Mediterranean Diet: A Heart-Healthy Approach
The Mediterranean diet emphasizes whole grains, fruits, vegetables, legumes, nuts, olive oil, and lean proteins like fish and poultry. This diet is rich in unsaturated fats, fiber, and antioxidants, which contribute to its cardiovascular benefits.MDPI+1BioMed Central+1
📊 Long-Term Evidence
A 20-year study known as the ATTICA study followed over 1,400 adults and found that those with high adherence to the Mediterranean diet had a 46.5% lower risk of developing hypertension compared to those with low adherence. Nature+2News-Medical+2Prevention+2
🧬 Genetic Factors
Research has also shown that the Mediterranean diet can mitigate genetic risks associated with hypertension, particularly in adolescents. The Sun+2PubMed+2News-Medical+2
🥩 The Ketogenic Diet: A Low-Carb Contender
The ketogenic diet is a high-fat, low-carbohydrate diet that induces a state of ketosis, where the body burns fat for energy instead of carbohydrates. This diet has gained popularity for weight loss and potential metabolic benefits.
📉 Short-Term Benefits
A recent study involving post-menopausal women with hypertension and obesity found that a very low-calorie ketogenic diet significantly reduced both brachial and central systolic/diastolic blood pressure levels over six months. PubMed+1ScienceDirect+1
⚠️ Considerations
While the ketogenic diet shows promise in the short term, some studies suggest that its benefits on blood pressure may not be sustained over the long term. Additionally, concerns have been raised about potential increases in LDL cholesterol levels and other cardiovascular risks. The Sun
⚖️ Comparing the Two Diets
Both diets have demonstrated the ability to lower blood pressure, but they differ in approach and sustainability.
-
Mediterranean Diet: Offers long-term cardiovascular benefits and is easier to maintain due to its balanced and inclusive nature.
-
Ketogenic Diet: May provide rapid improvements in blood pressure and weight loss but requires strict adherence and may have long-term health considerations.
A study comparing both diets found that participants experienced blood pressure reductions and weight loss on both diets over three months. However, the ketogenic diet group showed a higher level of "nocturnal dipping," a healthy drop in blood pressure during sleep. Medical News Today
🏁 Conclusion: Which Diet Wins?
If you're seeking a sustainable, heart-healthy diet with proven long-term benefits, the Mediterranean diet stands out as the preferred choice for lowering blood pressure. Its emphasis on whole foods and balanced nutrition makes it accessible and enjoyable for many.
The ketogenic diet may offer short-term benefits, particularly for weight loss and rapid blood pressure reduction. However, its restrictive nature and potential long-term health risks warrant caution.
Ultimately, the best diet is one that aligns with your health goals, lifestyle, and medical needs. Consulting with a healthcare professional or registered dietitian can help you make an informed decision.
