Sugar is everywhere in the modern diet, and it's silently driving a massive wave of chronic illness. From insulin resistance and fatty liver to cognitive decline, the overconsumption of ultra-processed, sugar-laden foods has created a health crisis hiding in plain sight. As scientists uncover deeper connections between sugar, metabolism, and brain health, one thing is clear: this isn’t just about cutting calories—it’s about changing the way we eat to protect our long-term well-being.

Today on The Dhru Purohit Show, we’re bringing you a special compilation episode featuring Dhru’s conversations with top experts on the connection between insulin resistance, fatty liver, and Alzheimer’s disease. 

Dr. Robert Lustig shares the impact of added sugar on mitochondrial health and metabolism. He also discusses what you can expect when significantly reducing the amount of added sugar in your diet, why the quality of your calories matters, and the fascinating ways our bodies store fat. 

Dr. Richard Johnson discusses his revolutionary new hypothesis on the link between fructose consumption and Alzheimer’s disease. Dhru and Dr. Johnson discuss the evolutionary mechanism behind fructose metabolism, insulin resistance, and weight gain, which has backfired due to its overconsumption.
