As interest in peptides continues to grow, experts are increasingly looking beyond weight loss to their potential role in healthy aging.
Functional medicine expert Dr. Will Cole told Fox News Digital that peptides are “intimately linked” to longevity, cellular healing and metabolic health.
“(Peptides) help with cellular communication,” said Cole, co-author of the upcoming book “Heal Your Cells.” Recommendations for peptides depend on the context in which they are used, he said, noting that the answer is often “somewhere in the middle.”
Citing previous research, Cole noted that about 93 percent of American adults are in poor metabolic health, leaving only about 7 percent who meet the criteria for optimal metabolic health — a number he called “wild.”
“It’s common, but not normal,” Cole said. He added that while GLP-1 drugs can be beneficial, improving metabolic health also requires addressing lifestyle and other underlying factors.
Cole said he doesn’t believe “macrodosing” GLP-1 “forever and in perpetuity” is the answer to improving metabolic health.
While GLP-1s may reduce cravings — often called “food noise” — and promote weight loss, Cole said he would like to see more research on how decreasing the desire for food might also decrease cravings for love, relationships and other mood-enhancing factors.
Cole wondered whether suppressing cravings might have unintended effects on other reward-related behaviors, including social relationships.
“So are we bypassing the pathways and pathologizing things that don’t need to be pathologized? »
Cole argued that some degree of hunger reporting is healthy. “Food noise is actually a decent thing, so shutting down your hunger signals with a dose of ‘atomic bomb’ peptide isn’t the answer.”
He added that he believes an over-reliance on GLP-1 drugs may contribute to disordered eating habits and a growing fear of hunger.
Cole attributed this trend to a culture that favors quick, easy fixes over lasting lifestyle changes. “We want a magic pill,” he said.
“And the truth is somewhere in between: Can we micro-dose? Can we do it cyclically? And can we tie it to a lifestyle?”
The expert questioned why there had been an “epidemic rise” in metabolic problems, pointing to factors such as diets high in ultra-processed foods, nutritional deficiencies, environmental toxins and the presence of stress and trauma.
“This is why we are seeing an increase in chronic health conditions, not a pharmaceutical deficiency,” he said.
Cole said he supports broader access to peptides, but stressed the importance of transparency, product purity and clear labeling so health professionals and consumers can make informed decisions.
Despite these concerns, Cole said he believes GLP-1s also hold therapeutic promise, citing their potential to reduce inflammation, help manage autoimmune diseases and improve gut health.
“But again, what is the lowest dose that gives a beneficial result based on lifestyle? I think that’s where peptides can really shine,” he said.
“And I’m actually more excited about some of these other (peptides), like the inflammation ones or the longevity peptides.”
