Gut Health Takes Center Stage at LongevityFest 2024
Longevity expert Dr. Peter Attia and Pendulum Therapeutics co-founder and CEO Colleen Cutcliffe, PhD explored one of 2024’s hottest topics: metabolic health and the role of the gut
2024 has emerged as a defining year for gut health, capped off by Pendulum co-founder and CEO Colleen Cutcliffe, PhD, and longevity expert Peter Attia, MD, who co-led a gut and metabolic health-focused session at LongevityFest 2024 in Las Vegas this month.
Hosted by the American Academy of Anti-Aging Medicine (A4M), the event featured the two experts delving into gut health, metabolism and longevity in a session titled “The Importance of Metabolic Health and the Relationship with the Gut: A Conversation.” In their discussions, Cutcliffe and Attia highlighted emerging scientific advancements and next-generation probiotic strains like Akkermansia muciniphila, while emphasizing the importance of medications and lifestyle modifications in addressing common metabolic wellness challenges.
Although Dr. Cutcliffe and Dr. Attia are both at the forefront in metabolic health solutions—Dr. Cutcliffe at the helm of a microbiome science-focused biotech company and Dr. Attia as the founder of Early Medical, a lifespan-centered practice—the duo emphasized that metabolic health is a complex issue requiring more than a one-size-fits-all approach.
“This is a very difficult problem to solve,” Dr. Attia noted. “And when solving difficult problems, I like to have multiple solutions.”
The discussion also explored the interconnected relationship between diet and the microbiome, highlighting how high-performing microbes stimulate GLP-1 production, generate short-chain fatty acids essential for metabolic health, and thrive on fiber- and polyphenol-rich diets. Interestingly, studies have shown that those with pre- and type 2 diabetes and obesity tend to lack such strains.
“Nutrition and the microbiome are tied at the hip… what you’re eating is feeding these microbes,” Dr. Cutcliffe said.
As Dr. Attia explained, Type 2 diabetes extends beyond insulin resistance, representing a wide-ranging dysfunction across multiple organs, referred to as the ‘Ominous Octet,’ and described it as an “organ-by-organ assessment of Type 2 diabetes.”
When discussing solutions to support metabolic wellness, Dr. Cutcliffe emphasized the importance of specific probiotic strains, such as Akkermansia muciniphila and Clostridium butyricum, which also play a role in promoting weight management
“When you don’t have those strains and they’re not able to perform their function, you may not able to stimulate GLP-1 production,” she explained. “Akkermansia muciniphila has sort of emerged as a keystone strain because it also regulates the mucin layer of your gut lining.”
In addition to consuming mucin, the strain can stimulate the production of new mucin. Without Akkermansia, however, the gut lining structure is disrupted, potentially affecting GLP-1 production.
