The College of Glycation with Dr. Paul Reynolds

Leaky Gut Meets RAGE

In this episode of the College of Glycation, Professor Paul Reynolds reveals how glycation and leaky gut don’t just coexist — they actively multiply each other’s damage. A diet high in heat-generated advanced glycation end-products (AGEs) reshapes the gut microbiome, weakens the intestinal barrier, and allows bacterial lipopolysaccharide (LPS) to leak into the bloodstream in a state called metabolic endotoxemia. At the same time, elevated glucose and dietary AGEs keep the RAGE receptor constantly engaged. Because RAGE and TLR4 (the LPS receptor) physically interact and upregulate one another in a feed-forward loop, the leaked LPS lands on an immune system that glycation has already primed — dramatically amplifying inflammation and insulin resistance through shared NF-κB signaling.Drawing on landmark studies from Cani, Qu, Snelson & Coughlan, Yan, Uribarri, and others, Reynolds shows that this synergy is not additive but multiplicative. The same modern dietary pattern that generates AGEs also opens the door for LPS and then lowers the threshold for its inflammatory effects. Practical takeaways include shifting to gentler, moisture-based cooking methods to slash dietary AGEs, feeding butyrate-producing bacteria with fiber and dairy fats to strengthen tight junctions, and controlling blood glucose and insulin to disengage RAGE and raise the inflammatory threshold. Ultimately, glycation is reframed not merely as tissue damage, but as a recalibration of immune judgment — turning an ordinary bacterial leak into the spark that meets the gasoline.

Glycocalyx and the Role of Glycation

In this episode of the College of Glycation, Paul Reynolds flips the script on sugar. While glycation is usually portrayed as the villain that damages proteins, lipids, and DNA through advanced glycation end products, today he reveals a place where sugar is actually the hero: the glycocalyx. This dense, gel-like sugar coat covers nearly every cell in your body, with its most important version lining the inside of all your blood vessels like an invisible protective forest.Paul explains the structure of the glycocalyx, its surprising thickness, and its four critical roles as a selective filter, a shear-stress sensor that triggers nitric oxide release, a physical and electrical barrier against clotting and inflammation, and a non-stick coating for smooth blood flow. He then shows how high blood sugar rapidly destroys this layer—halving its volume in just six hours through oxidative stress and the AGE-RAGE pathway that activates heparanase. The breakdown of the glycocalyx appears to be one of the earliest events in vascular dysfunction, atherosclerosis, and kidney disease, while also contributing to leaky gut. The solution, Paul argues, is the same approach that protects the rest of the body: keeping blood glucose stable and low so the cell can build and maintain this life-saving sugar coat instead of tearing it down.Paul’s favorite yerba mate: https://unicity.link/121f260bfe Yerbe mate with a special formulated Balance fiber: https://ufeelgreat.com/c/PaulReynolds For the full Metabolic System storefront: https://shop.unicity.com/paulreynolds Paul’s favorite source for clean, earth-sourced essentials such as salt, electrolytes, hydration, pre-workout and more.

Adipose Glycation and Fat Cell Hypertrophy

Podcast Episode Description:In this eye-opening episode of the College of Glycation, Professor Paul Reynolds explores adipose glycation — the hidden process where fat cells themselves become chemically modified by sugar, turning them into drivers of metabolic dysfunction. Far from being passive storage tanks, hypertrophic adipocytes generate their own glycating agents like methylglyoxal (MGO), activating the AGE-RAGE axis, inflammation, hypoxia, and fibrosis. This creates a self-reinforcing loop that promotes insulin resistance, cytokine release, and impaired fat expandability — explaining why fat cell size and behavior matter far more than total body fat.Drawing on key studies, Reynolds connects the dots between chronic hyperinsulinemia, fructose intake, RAGE-driven hypertrophy, and the breakdown of healthy adipose remodeling. The episode reveals why some people develop metabolic disease at lower BMIs and offers practical, empowering strategies: lower insulin through carb restriction and time-restricted eating, minimize fructose, support the glyoxalase system, and stay active to keep fat cells healthy and quiet. A must-listen for anyone interested in body composition, inflammation, and breaking the cycle of metabolic illness.Paul’s favorite yerba mate: https://unicity.link/121f260bfe Yerbe mate with a special formulated Balance fiber: https://ufeelgreat.com/c/PaulReynolds For the full Metabolic System storefront: https://shop.unicity.com/paulreynolds Paul’s favorite source for clean, earth-sourced essentials such as salt, electrolytes, hydration, pre-workout and more.

GLP-1 Beyond Glucose

In this eye-opening episode of the College of Glycation, biomedical scientist and Professor of Cell Biology Paul Reynolds goes beyond the headlines on the blockbuster GLP-1 receptor agonists—semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound). While everyone talks about dramatic weight loss, Reynolds reveals what these drugs are actually doing at the cellular level: directly downregulating the RAGE receptor, suppressing AGE-induced inflammation, and powerfully activating autophagy. Drawing on landmark trials like SELECT (which showed a 20% drop in major cardiovascular events even in people without diabetes), he demonstrates how these benefits stem from four overlapping anti-glycation mechanisms that go far deeper than glucose control or appetite suppression. Reynolds walks listeners through the full family of incretin therapies, the science of the dangerous AGE-RAGE-NF-κB axis, and how GLP-1 agonists restore cellular recycling by shifting the AMPK-mTOR balance—clearing damaged, glycated proteins in ways that explain their impressive tissue-protective effects. He closes with a balanced, practical perspective: these are powerful pharmacologic tools that mimic healthy metabolic states, but they work best as temporary bridges to real food, movement, sleep, and fasting rather than lifelong crutches. If you want to truly understand why metabolic dysfunction drives chronic disease—and what the GLP-1 story teaches us about fixing it at the root—this episode is essential listening.

Autophagy and Glycation

In this episode of the College of Glycation, Dr. Paul Reynolds explores autophagy—one of the body’s most powerful yet underappreciated defenses against aging. Autophagy, the Nobel Prize-winning cellular “self-eating” process, allows cells to identify, package, and recycle damaged proteins, dysfunctional mitochondria, misfolded molecules, and glycated junk before they mature into advanced glycation end-products (AGEs). These sugar-modified compounds stiffen tissues, impair insulin signaling, promote inflammation, and accelerate chronic disease. Dr. Reynolds explains how constant eating and elevated insulin keep autophagy suppressed, trapping cells in perpetual “build and store” mode and allowing glycation damage to accumulate.Intermittent fasting changes everything by lowering insulin, suppressing mTOR, and activating AMPK—triggering the metabolic switch that rapidly ramps up autophagy and delivers a true glycation reset. Drawing on landmark research, Dr. Reynolds shows how even short fasting windows (like 16:8) can clear glycated proteins, improve metabolic health, and support cellular renewal. He offers practical, step-by-step guidance for beginners through advanced fasters, while clearly outlining who should avoid fasting and how to combine it with smart eating and exercise for maximum benefit. This episode delivers the science and the actionable strategy to harness your body’s built-in cellular housekeeping system.Paul’s favorite yerba mate: https://unicity.link/121f260bfe Yerbe mate with a special formulated Balance fiber: https://ufeelgreat.com/c/PaulReynolds For the full Metabolic System storefront: https://shop.unicity.com/paulreynolds Paul’s favorite source for clean, earth-sourced essentials such as salt, electrolytes, hydration, pre-workout and more.
