Which diet lowers blood pressure more: keto or Mediterranean?

A pilot study comparing a low-calorie, high-protein ketogenic diet and a Mediterranean diet in overweight and obese adults with elevated blood pressure found that both diets led to significant weight loss, improved body composition, and reduced blood pressure. Both dietary approaches were safe and well-tolerated, but the Mediterranean diet group showed a greater proportion of participants with healthy nocturnal blood pressure dipping.
