Abstract
Obesity and cardiovascular diseases are major health problems worldwide, and weight loss is used as a treatment strategy to enhance various aspects. While there are many weight loss methods, one of the most effective is through a dietary approach. The ketogenic diet (KD), which is characterized by low carbohydrates and high levels of fat and/or protein, is used in obese patients as it is a promising treatment option for weight loss as well as for controlling the risk factors for cardiovascular diseases, as seen in its effects on cardio-metabolic outcomes, particularly in obesity, heart failure, and hypertension. In this review, we summarize the clinical evidence of the efficacy and safety of the KD in controlling risk factors for cardiovascular diseases and discuss the possible mechanisms of action based on recent evidence in understanding the influence of the KD at the cellular and molecular levels.
