He has over 20 years of experience in the medical field, receiving his concurrent medical and immunology degrees from University of Edinburgh in 2001. Dr. Chatterjee is one of the most recognizable physicians in British Media, known for his work with the BBC as lead resident doctor on BBC Breakfast and as a regular commentator on BBC Radio. Dr. Chatterjee is the author of six books since 2017. His overall goals in the health space are to simplify health to be comprehensive to all, approaching health using progressive medicine to reduce and prevent chronic disease, and challenge modern health tools and information.

In today’s episode, Dr. Holmes and Dr. Chatterjee discuss the need to wake up to the things that are tying you down (0:40), the important role of solitude and self-reflection in growth (06:57), and how to find your inner calm (10:27).
