CNN.com: Can GLP-1 Drugs Slow Aging?
CNN.com and Everyday Health recently interviewed James Kirkland, MD, PhD, director of the Center for Advanced Gerotherapeutics at Cedars-Sinai, and Amanda Velazquez, MD, director of Obesity Medicine at the Center for Weight Management and Metabolic Health, about balancing the potential benefits of GLP-1 weight loss medications and the importance of realistic expectations and medical guidance.
Preliminary research suggests GLP-1 medications may influence biological markers associated with aging and improve obesity, diabetes, heart disease, inflammation and sleep apnea. However, experts say it remains unclear whether these benefits stem directly from the medications or from the weight loss they cause.
Kirkland cautioned against taking GLP-1s solely in hopes of living longer. He expressed concerns about healthy, lean people using the medications off-label to optimize their health and longevity, a practice known as “biohacking.” The long-term risks of GLP-1 use among younger people without obesity remain unknown.
“My concern is that people could overread some of this stuff,” he told CNN.com.
Kirkland added that measures used in recent studies to estimate biological aging—such as changes in gene activity and protein levels—are still evolving. While these tools can be useful for studying large groups of people, he said, they do not yet offer reliable health information for an individual.
“They can vary tremendously from day to day within a person,” he told CNN.com.
Unrealistic expectations around GLP-1s extend beyond longevity claims to the weight loss process itself, where patients frequently experience frustrating plateaus.
Velazquez explained to Everyday Health that as people lose weight, metabolism naturally slows—especially when muscle mass is lost—while appetite-regulating hormones adapt to increase hunger and reduce the feeling of fullness.
“So essentially, your body is working against you and making it harder for you to lose weight as you continue the process,” she said. “These hormone signals get stronger with time and the more weight you try to lose.”
To safely overcome these plateaus, Velazquez recommended consulting a healthcare provider for personalized guidance on medication adjustments, proper nutrition, sleep, stress management and exercise.
