3 things heart doctors do to boost longevity and health: Check their science-backed tips

Everyone wants to live a longer, healthier life, but few know exactly how to achieve it. Heart doctors, who spend their careers treating cardiovascular diseases, often follow evidence-backed practices themselves to optimize their own longevity. Their lifestyle choices, grounded in scientific research, reveal practical ways to reduce the risk of chronic diseases, boost heart health, and improve overall wellness.

A board-certified cardiologist, popularly known as Doctor Alo, recently shared three key habits he personally follows, which are rooted in scientific research.

Maintaining an Ideal Body Weight

According to Doctor Alo, one of the most important steps for a longer life is staying as close to your ideal body weight as possible. Scientific studies consistently support this approach. Research shows that an elevated body mass index (BMI) increases the risk of type 2 diabetes, cardiovascular disease, and several types of cancer.


The World Health Organization recommends maintaining a BMI between 18.5 and 24.9 kg/m² to reduce the risk of chronic illnesses and premature mortality. By keeping body weight in check, cardiologists aim to minimize strain on the heart and support metabolic health.

Embracing Mediterranean-Style Diet

Diet is another cornerstone of longevity for heart doctors. The Mediterranean diet, widely recognized for its heart benefits, is central to this approach.

Mayo Clinic notes that the diet focuses on plant-based foods like vegetables, fruits, beans, nuts, and whole grains, while incorporating healthy fats such as olive oil. Seafood, poultry, and eggs are included in moderation, and red meat is limited. Studies have shown that this diet reduces risk factors for cardiovascular disease, including high cholesterol, high blood pressure, obesity, and diabetes. Following this eating pattern long-term has been associated with lower incidence of heart disease and improved overall wellness.

Engaging in Enjoyable Physical Activity

Finally, Doctor Alo emphasizes the importance of regular physical activity—but with a twist. Instead of rigid exercise routines, he encourages finding an activity you genuinely enjoy and can sustain for life.


A study published in the Journal of Global Health in July 2025 found that individuals engaged in hobbies or recreational activities had a 29% lower risk of all-cause mortality across 19 countries. Whether it’s swimming, cycling, or dancing, the key is consistency and enjoyment, which supports cardiovascular health, reduces stress, and enhances quality of life.

By combining ideal body weight management, a Mediterranean-style diet, and enjoyable physical activity, heart doctors aim to optimize both lifespan and health. Scientific evidence validates these strategies, showing that small, sustainable lifestyle choices can have a significant impact on longevity. For those seeking guidance on healthier living, following these principles provides a practical and research-backed pathway to a longer, heart-healthy life.
