Dr Alexandra Lim holds a PhD in Neuropsychiatry and a Master's degree in Clinical Nutrition. She works at the intersection of gut health, mood, and metabolism, translating complex science into tools people can actually live by.

Her work is shaped not only by research, but by lived experience. GUTSY explores the gut-brain-metabolism connection through both rigorous science and personal experimentation, challenging the idea that health and vanity must sit at odds. Instead, it reframes clarity, regulation, and effortless aesthetics as biological outcomes of a well-functioning system.

Outside of writing and research, Alexandra enjoys long walks, Pilates, yoga, cooking new recipes, and lives by the philosophy that how you digest food is how you digest life.
