The Fasting-Mimicking Diet and its Cardiovascular Benefits
The Fasting-Mimicking Diet and its Cardiovascular Benefits
In the quest for optimal cardiovascular health, a healthy diet plays a crucial role. Various diets, like the Mediterranean diet, have been shown to protect heart health. However, recent research conducted by the University of Southern California suggests that the fasting-mimicking diet may offer unique benefits for cardiovascular health when compared to other diets.
Understanding the Fasting-Mimicking Diet

The fasting-mimicking diet is a 5-day vegan diet designed to mimic the effects of water-only fasting on the human body. Developed by Dr. Valter D. Longo, a renowned gerontology expert, this diet is composed of low-calorie, low-protein, and high-fat plant-based foods. Unlike traditional fasting, individuals following the fasting-mimicking diet continue to eat during the “fasting” period.
The Potential of the Fasting-Mimicking Diet
The fasting-mimicking diet has garnered attention not only for its potential cardiovascular benefits but also for its potential in cancer treatment. Studies have shown that this diet may slow down tumor growth and enhance the effectiveness of chemotherapy in certain types of cancer. Additionally, it has been investigated for its potential benefits in breast cancer therapy, multiple sclerosis, cardiometabolic disease, autoimmune diseases, inflammatory bowel disease, skin issues, and Alzheimer’s disease.

Comparing the Fasting-Mimicking Diet to the Mediterranean Diet
The University of Southern California conducted a study comparing the effectiveness of the fasting-mimicking diet to the Mediterranean diet in reducing the risk of cardiovascular disease among adults with obesity and hypertension. The study involved 84 participants between the ages of 35 and 75, all with a body mass index (BMI) of 28 or above.
During the study, half of the participants followed the fasting-mimicking diet for four months, while the other half followed the Mediterranean diet. The researchers evaluated various measures, including reactive hyperemia index (RHI), small and large arterial compliance (AC1/AC2), and blood pressure.
Unique Heart-Healthy Effects of the Fasting-Mimicking Diet
The results of the study indicated that the fasting-mimicking diet group experienced a reduction in reactive hyperemia compared to the Mediterranean diet group. Reactive hyperemia is associated with heart function and overall cardiovascular health. Dr. Longo suggests that this reduction in reactive hyperemia may be indicative of heart rejuvenation, although further research is required to establish this.

Furthermore, the fasting-mimicking diet group showed reductions in biological age, heart age, and their Protein Unstable Lesion Signature (PULS) cardiac test scores. These scores evaluate an individual’s 5-year risk of stroke. The fasting-mimicking group also experienced a decrease in trunk fat mass without a decline in lean muscle mass, unlike the Mediterranean diet group.
Expert Insights on the Findings
Cardiologist Dr. Rigved Tadwalkar finds the findings of the study encouraging. He highlights that both the fasting-mimicking diet and the Mediterranean diet led to weight loss and improvements in blood pressure, cholesterol, and blood sugar – all important factors in cardiovascular health. Additionally, the fasting-mimicking diet showed the added benefit of reducing abdominal fat, a significant risk factor for cardiovascular disease.
Registered dietitian nutritionist, Monique Richard, emphasizes the importance of individual needs and the complex interaction between nutrients and the body. She suggests that while the fasting-mimicking diet can be beneficial for many individuals, it should not be seen as a standalone solution or a long-term alternative. Instead, a comprehensive approach that includes intentional modifications to dietary patterns and lifestyle is necessary for significant changes over time.
Incorporating the Fasting-Mimicking Diet into a Healthy Lifestyle
When considering the best diet for both weight loss and heart health, it is essential to find a dietary pattern and lifestyle that aligns with an individual’s unique needs. Consulting with a registered dietitian nutritionist (RDN) can provide personalized recommendations based on factors such as medical conditions, genetic predisposition, preferences, and cultural traditions.
A diet that supports cardiovascular health should include foods rich in vitamins, minerals, and phytochemicals. These include fruits, vegetables, legumes, nuts, seeds, plant fats, lean proteins, fermented foods, and whole grains. Understanding portion sizes, preparation methods, and frequency of consumption is also crucial for maintaining a heart-healthy diet.
Conclusion
The fasting-mimicking diet offers a unique approach to cardiovascular health. While further research is needed to fully understand its long-term effects, studies have shown promising results in terms of reducing the risk of cardiovascular disease and improving various cardiovascular markers. Incorporating the fasting-mimicking diet into a healthy lifestyle, under the guidance of a healthcare professional, may provide individuals with an effective tool for maintaining heart health and overall well-being.
Additional Information: It is important to note that before making any significant dietary changes, individuals should consult with a healthcare professional to ensure the diet is appropriate for their specific circumstances and health conditions.
