The world of obesity treatment has been transformed by the groundbreaking discovery and development of GLP-1-based drugs. The 2024 Lasker~DeBakey Clinical Medical Research Award honored three pioneering scientists—Joel Habener, Svetlana Mojsov, and Lotte Bjerre Knudsen—whose research into GLP-1 (Glucagon-like peptide-1) has revolutionized weight management and offered new hope for millions of people struggling with obesity.
What is GLP-1 and How Does It Work?
GLP-1 is a naturally occurring hormone in the body that plays a crucial role in regulating blood sugar levels by promoting insulin secretion. Initially, GLP-1 was studied for its potential in diabetes treatment, as it helps control blood sugar. However, its impact on appetite suppression soon became clear when Dr. Stephen Bloom of Hammersmith Hospital in London discovered that injecting GLP-1 into rats’ brains caused a significant reduction in appetite. This finding was a key turning point for the future of obesity treatment.
Lotte Bjerre Knudsen, a researcher at Novo Nordisk, took this discovery further. She realized that GLP-1’s effect on weight loss was separate from its role in blood sugar regulation. Her innovative idea was to extend the hormone’s effect by attaching it to a fatty acid that binds to albumin, making it last longer in the body. This research led to the development of liraglutide, known as Saxenda, the first GLP-1-based drug approved for obesity treatment.
The Impact of GLP-1 Drugs on Weight Loss
Saxenda marked the beginning of a new era in obesity treatment, but it was only the start. Novo Nordisk’s scientists continued to refine GLP-1 analogs, eventually developing semaglutide, which was first released as Ozempic for diabetes and later approved as Wegovy for obesity. What makes Wegovy stand out is its unprecedented success in promoting weight loss. While traditional obesity treatments aimed for a 10% weight loss—considered an impossible dream for many—Wegovy patients saw an average of 15% weight loss, breaking long-standing barriers in obesity research.
The success of these GLP-1-based drugs highlights the role of appetite regulation in obesity. For many individuals, diet and exercise alone are not enough to manage their weight. The development of GLP-1 medications has provided a medical intervention that addresses the complex biological factors contributing to obesity.
The Global Obesity Crisis
Nearly 900 million adults around the world are living with obesity. In the United States, 40% of adults are affected, and in Europe, the prevalence approaches 25%. Obesity is not just about appearance; it is a serious health condition linked to multiple life-threatening diseases, including heart disease, type 2 diabetes, and certain cancers. The perception of obesity as a lack of willpower has long been a barrier to effective treatment. But research like that of Habener, Mojsov, and Knudsen is changing the narrative, offering scientifically backed, effective treatments that go beyond lifestyle changes alone.
What Does the Future Hold for GLP-1 Drugs?
The development of GLP-1-based drugs like Wegovy and Saxenda has set a new standard for obesity treatment, but the progress doesn’t stop here. As researchers continue to explore the full potential of GLP-1 and related compounds, we can expect to see even more advanced treatments in the future. These breakthroughs will continue to improve health outcomes for people with obesity, helping them achieve meaningful, long-term weight loss and better overall health.
