Dr. Sebastián La Rosa, a specialist in longevity medicine, emphasized the importance of consuming the majority of daily food intake before 3 p.m., according to recent statements he made during his ongoing public lectures. La Rosa, who has built a reputation through both clinical practice and extensive outreach efforts, advocates for sustainable health strategies grounded in scientific evidence. His work spans nutrition, metabolism, training, sleep, and biomarker analysis, with a focus on personalized and preventive approaches to health. La Rosa’s journey into longevity medicine began with diverse studies in homeopathy and traditional Chinese medicine, which he later expanded upon through travel and research in Asia. He now describes his specialization as the best expression of possible health, stressing the need to maintain optimal function of each organ system in order to live longer and healthier lives. As a professor in medicine and a doctor honoris causa, he combines academic rigor with practical application, offering insights through his widely followed YouTube channel, which boasts over six million subscribers. In addition to his educational efforts, La Rosa founded Pulso AI in 2025, a platform integrating artificial intelligence, biomarkers, and nutritional science to provide tailored recommendations aimed at optimizing biological performance and overall health. His lecture series, titled “The Five Habits to Live Longer,” travels across Argentina and underscores his mission to promote personalized and preventive medicine, aiming to extend life expectancy while improving quality of life. Reflecting on his personal motivations, La Rosa shared that growing up in a family inclined toward alternative and holistic medical practices had a negative impact on his health. Specifically, a restrictive macrobiotic diet during childhood led to nutrient deficiencies, prompting him to seek more objective, evidence-based solutions. This experience inspired his current work, which he says resonates with many others facing similar challenges. When asked about the five habits he promotes for living longer and better, La Rosa clarified that they are more accurately described as fundamental changes rather than mere routines. These include revisiting the basics of nutrition, two aspects of exercise, sleep quality, and the personalization of health strategies. Personalization, he noted, presents the greatest challenge since different individuals respond differently to various interventions. Identifying the specific actions that yield the highest impact for each person is crucial in determining priorities effectively. Regarding nutrition, La Rosa stressed the significance of addressing essential elements such as portion size and nutrient balance, often overlooked in favor of restrictive diets or short-term protocols. He outlined three key questions that can help structure dietary choices more sensibly: what to eat, when to eat it, and how much of each item to consume. These considerations offer a comprehensive approach to nutrition, moving beyond specific diets or temporary restrictions. When discussing the diet with the strongest scientific backing for longevity, La Rosa pointed to the Mediterranean diet, highlighting five modifications that enhance its effectiveness. These include reducing dairy consumption, moderating grain intake, increasing plant-based foods, incorporating healthy fats, and maintaining regular physical activity. The Mediterranean diet, supported by substantial research, aligns with the principles of balanced nutrition and lifestyle adjustments that contribute to extended lifespan and improved well-being.
