Brain Energy Reset: Metabolic Mental Health & Ketogenic Therapy Power w/ Moira Newiss
In this eye-opening episode, we explore one of the most exciting shifts in modern mental health: the discovery that mental health is deeply rooted in metabolic health. When the brain’s energy supply falters, everything from mood to memory to emotional resilience can be affected — and new research is revealing how nutrition and lifestyle can restore balance.
Our guest, Moira Newiss, is a BANT-registered nutritional therapist, health coach, and accredited ketogenic metabolic therapy expert who specializes in brain energy — a newly recognized root cause of many mental health challenges. Moira helps clients understand what’s happening in their biology and guides them through simple, practical changes that spark real transformation. Her work is grounded in hope, clarity, and the belief that people can not only feel better but truly get their lives back on track.
Together, we unpack how ketogenic diets can provide a cleaner, more efficient fuel source for the brain through ketones, helping stabilize brain energy and improve mental well-being. Moira also explains why diet is only one piece of the puzzle — and how sleep, light, movement, and stress balance each play essential roles in optimizing brain metabolism.
