Improving Biological Age with GLP-1 RAs: An Analysis of a Study 

This is a further dive into and expansion of a Journal Club video that I offered in September 2025 in response to a fascinating article related to the power of GLP-1 peptides to create positive epigenetic changes at the cellular level. 

The study, Semaglutide Slows Epigenetic Aging in People with HIV-associated lipohypertrophy: Evidence from a Randomized Controlled Trial, is in preprint and has not yet been peer-reviewed, but offers substantive evidence of semaglutide’s versatile effects on cellular pathways related to metabolism, inflammation, and the immune system. In particular, the study examines the use of semaglutide (a GLP-1 receptor agonist) to control or slow the epigenetic aging of people with HIV (PWH) and  associated lipohypertrophy, a common condition with this population of patients. 

Through the lens of “the emerging geroscience paradigm” (Kennedy,et al, 2014), the study authors suggest that HIV-associated lipohypertrophy (a condition characterized by excessive accumulation of visceral and ectopic adipose tissue) offers an opportunity to examine the impact of semaglutide on a cohort who represent the “accelerated-aging phenotype” and look at possible implications for GLP-1 RAs as agents that improve biological age.

I was drawn to this article because of its focus on the pleiotropic power of GLP-1 RAs, a topic that I’ve discussed in several Masterminds, focused on in my soon-to-be released weight loss course, and devoted an entire book to – The Quantum Power of GLP-1 Peptides (SSRP, 2025). As we know from the plethora of existing research, GLP-1 peptides such as Semaglutide decrease inflammation, improve metabolism, and support the immune system. The two-part question that the article prompted for me was this: if GLP-1 RAs can positively affect cellular metabolism, immune function, and inflammation, thereby altering the cellular environment, wouldn’t it make sense that they also have the potential to increase the healthspan – or lifespan – of the cell? And I think the answer, intuitively, is – absolutely.
