Scientific knowledge of the gut microbiome has increased exponentially over the last decade. Recently, several studies have suggested that specific strains of bacteria, including Akkermansia muciniphila, are key to supporting the environmental conditions required for other related bacterial strains that facilitate healthy metabolic health. In this video, Colleen Cutcliffe, PhD, co-founder and CEO of Pendulum discusses groundbreaking research around Akkermansia mucinophila, the role of short-chain fatty acids (SCFAs) in stimulating GLP-1 pathways, implications for diabetes management, and how gut bacteria influence inflammation, gut integrity, and overall metabolic health. They also explore how diet, antibiotics, and stress impact the microbiome, potential roles of probiotics in inflammatory bowel disease (IBD), pediatric gut health, and exciting emerging research on the gut-brain axis and neurological conditions like Parkinson's disease. Colleen highlights Pendulum's rigorous scientific approach, including clinical trials and innovative manufacturing practices that ensure product viability and effectiveness.

In this episode, we talk about a recent study from Nature Aging that suggests aging may not progress in a straight line. Using data from thousands of biological measurements, researchers identified key ages—44 and 60—where changes in aging appear to accelerate. We review what this means for our understanding of aging, how it affects multiple systems in the body, and the potential implications for health and disease. We also discuss what this study tells us—and doesn’t tell us—about the biology of aging and how it could guide future research.

Can we slow the speed of aging? In this episode, Dr. Varun Dwaraka, Head of Bioinformatics at TruDiagnostic, walks us through through the science of measuring "biological age" using epigenetic markers, such as DNA methylation. We discuss how epigenetics (i.e. DNA methylation), may provide biomarkers of biological age, the rate at which aging occurs, and potentially early markers of disease. Dr. Dwaraka explains the distinctions between chronological and biological age, the development and refinement of epigenetic clocks, and the potential applications of these tools in aging interventions. The conversation also addresses the mechanisms of epigenetic regulation, the influence of lifestyle factors on biological age, and the future role of epigenetics in predicting and managing age-related diseases. Additionally, we examine the data science that underpins these clocks, their targeted outcomes, and a recent study published by Dr. Dwaraka and colleagues comparing aging biomarker outcomes in a vegan vs. omnivore diet intervention among twins.

Highly processed foods have been shown to lead to weight gain and are thought to drive intake through several mechanisms. Recent research suggests that the effect of combining fats and carbs on appetite might be more than the sum of their individual effects. Highly processed foods, accordingly, might simulate increased intake via the ratio of macronutrients.

In this episode, we discuss how overeating can lead to inflammation and neuron dysfunction in specific parts of the brain that control appetite and energy regulation. We review the neuroscience of appetite regulation, energy expenditure, and body fat regulation. Topics include hypothalamic dysfunction of body fat regulation, leptin resistance, neuro-inflammation, and physical changes in the hypothalamus involving microglia (the immune cells of the brain). We also review what is known about avoiding and reversing these changes.

Is it possible to be metabolically healthy and overweight or obese? In this episode, we discuss the science of what makes fat healthy or unhealthy. We discuss how metabolic dysfunction in fat tissue can affect the rest of the body. We also review evidence pertaining to the "obesity paradox" and explore explanations for the associations of body mass index (BMI) and changes in the risk of disease complications and mortality. We discuss how metrics of central obesity can be used to obtain a better picture of an individual's metabolic health. Lastly, we discuss the critical link between exercise capacity and future health, as well as how to begin to transform our existing fat stores into a healthier state.

This is our first episode on weight gain and weight loss. In this episode, we describe how, as an industrialized nation, our food supply and environment have changed in a way that, in many cases, is mismatched with our biology as humans. We explore how these changes can lead to disease and metabolic dysfunction. We discuss how the replacement of whole foods with processed foods, as well as the addition of caloric sweeteners to most of the food items within grocery stores across the nation has preceded a rapid rise in obesity and metabolic dysfunction. In this episode, we begin to discuss some of the pathophysiology related to the consumption of ultra-processed and hyper-palatable foods as well as concerns surrounding the consumption of fructose- and glucose- containing sugary drinks. We also discussed the timelines of weight gain and loss as they typically occur over the lifespan and vary according to season. This episode sets the stage for the next episodes, which will focus on the normal fat metabolism and how it may become dysregulated in metabolic dysfunction.
