This episode features host Andy McBride and Dr Estrelita Van Rensburg discussing nutrition and its impact on health and performance. Dr Van Rensburg, a former medical doctor, explains how the human diet has evolved over millions of years, highlighting the significance of meat consumption in brain development and changes in our digestive system. The conversation then shifts to modern dietary practices and their potentially harmful effects, particularly the overconsumption of processed foods and carbohydrates, which can lead to insulin resistance and various chronic diseases. Dr Van Rensburg advocates for a return to a diet rich in real, nutrient-dense foods like meat, fish, and healthy fats, recommending personal experimentation and the use of a continuous glucose monitor to understand individual responses to food. The episode concludes by emphasising the importance of taking personal responsibility for one’s health and encouraging listeners to consider making dietary changes for improved well-being.
