Dr. Richard Johnson, a renowned professor of medicine, delves into the biological mechanisms behind obesity and related diseases in his presentation, "A Tale of Two Sugars." He explores the impact of fructose, a type of sugar found in fruit and added sugars, on metabolic health and how it drives conditions such as diabetes, obesity, and Alzheimer's disease. Johnson explains how fructose triggers hunger, insulin resistance, and fat storage, and contrasts this with allulose, a natural sugar substitute that offers potential health benefits without activating the harmful metabolic pathways associated with fructose. He concludes with insights on the role of diet, particularly lowcarb and ketogenic diets, in preventing and managing these diseases.
