In this episode, Dr. Kashey summarizes his previous lessons about sugar's toxic effects on health. He emphasizes the importance of understanding how sugar affects obesity and non-communicable diseases and discusses the keys to maintaining metabolic health. Dr. Kashey also talks about the behavioral and physiological aspects of food and eating and the impact of exercise on metabolic health. He explains how consuming sugar affects the liver, which can lead to high blood sugar levels, and discusses the importance of fasting before blood work. He then talks about the confusion that can arise when clinicians use blood sugar levels to measure health and advises against the misconception that being healthy means having low numbers in blood work.
