Episode notes

New drugs targeting glucagon-like peptides (GLP-1) effectively engage both the hormonal and reward pathways in the brain, influencing eating behaviors. By blocking glucagon secretion, these drugs help regulate cravings and prevent glucose spikes that typically drive hunger. This dual action promotes delayed gastric emptying, supporting anti-obesity and anti-diabetic effects. Their design capitalizes on the connection between gut hormones and brain reward systems, making them beneficial for managing weight and diabetes simultaneously.

Today on The Human Upgrade, Dr. Anurag Singh, a renowned expert in muscle biology and aging, shares his expertise on the impact of GLP-1 agonists like Ozempic and Wegovy on weight loss, muscle health, and aging. In this episode, you'll learn about the science behind these popular drugs, their potential benefits, and the risks involved. Discover how you can maintain muscle mass while losing weight, enhance your mitochondrial function for better health, and what the future holds for medical treatments in weight management. Gain expert insights into making smart choices for your long-term health and wellness, whether you're considering these treatments or just curious about new health technologies.
