In this episode of the Radical Health Rebel Podcast, Dr. Tetyana Obukhanych — immunologist and gut health expert — shares both her scientific expertise and personal journey with chronic gut health issues.

She explores how vaccines, glyphosate, and gluten impact the gut and immune system, and explains the difference between IgE and non-IgE allergies. Tetyana also opens up about her struggles with chronic fatigue and gut dysfunction, and how dietary changes and alternate day fasting played a key role in her healing. The conversation covers time-restricted eating, metabolic individuality, fasting for women, exercise, hormone balance, and how fasting can rejuvenate gut stem cells.
