In this episode of Longevity by Design, host Dr. Gil Blander welcomes Dr. Eran Segal, Professor at the Weizmann Institute of Science, to explore the intersection of artificial intelligence (AI) and personalized health. The conversation dives into how AI and machine learning are transforming our understanding of nutrition, disease prediction, and overall longevity. Eran provides a clear overview of AI, machine learning, and deep learning, explaining how these technologies can be applied to various health domains.

Eran discusses the potential of AI agents in healthcare, such as scheduling appointments, managing medications, and even creating personalized dietary recommendations. He highlights the importance of data in training AI models, noting that the healthcare industry lags behind in publicly available and diverse data sets. The 10K Initiative, a project Eran leads, aims to address this issue by collecting comprehensive data on individuals to build more holistic AI models for personalized health.

Gil and Eran consider the future, envisioning AI-powered digital twins that can simulate the impact of lifestyle changes on disease development. While AI offers exciting possibilities, Eran cautions against over-reliance, emphasizing the need for continued human oversight and validation. He reiterates that the foundation of longevity still relies on simple habits: sleep well, eat well, and exercise regularly.
