AGING IS A SCIENCE: What To Eat & When To Eat To SLOW THE AGING Process | Matt Kaeberlein
Dive into the science of aging with Matt Kaeberlein as he talks about potential interventions, the role of diet, and the importance of personalized approaches to health.
The podcast explores the features of caloric restriction, the impact of genes on lifespan, and the potential of drugs like rapamycin.
Additionally, the role of exercise and other lifestyle factors, as well as the importance of comprehensive biomarker measurement, are discussed.
Influence of Lifestyle Factors on Aging
Lifestyle factors like exercise, nutrition, and fasting can significantly influence the body’s ability to heal and repair itself.
Interventions for aging should be based on individual responses for optimal results.
Comprehensive measurement of biomarkers provides insights into aging processes and identifies areas for intervention.
Personalized Approaches to Aging
The rapidly changing environment necessitates a personalized approach to aging.
Comprehensive data gathering through biomarkers and blood panels is essential for extending lifespan.
The ultimate goal of interventions for aging is to optimize functionality, vitality, and youthfulness.
Early Detection and Intervention
Diagnostics like carotid scans, calcium CT scans, and whole-body MRIs can help catch potential health problems early.
High-dimensional proteomics and metabolomics can provide insights into overall health and metabolism.
Rapamycin, traditionally used for organ transplants, has shown promising results in reversing ovarian degeneration in mice and restoring fertility.
Rapamycin: A Potential Anti-Aging Drug
Rapamycin shows potential in reversing functional declines in aging mice, but its effectiveness in humans is still speculative.
The potential benefits of rapamycin outweigh those of metformin based on pre-clinical work.
Resilience, or the ability to quickly return to baseline, is considered a phenotype of aging and can be measured through functional markers.
The Impact of Modern Lifestyle on Health
Our modern diet and sedentary lifestyle’s impact on healthspan and life expectancy remains to be seen, but the prevalence of unhealthy diets and sedentary behavior is a major concern.
The microbiome plays a role in adjusting food cravings and potentially impacting weight set points.
A balance between a healthy lifestyle and occasional indulgences is important.
The Obesity Epidemic
The obesity epidemic may not be solvable with medicine alone, as current anti-obesity drugs have potential side effects and rebound effects when discontinued.
Understanding the changes in brain chemistry associated with certain foods that reinforce unhealthy behaviors and contribute to obesity is crucial.
There’s a much easier argument that what aging really is is an absence of selection… biological aging to some extent is an accident of evolution. – Matt Kaeberlein
The Dog Aging Project
The Dog Aging Project is the largest open science project for canines, aiming to increase health and longevity in pet dogs.
By studying aging in dogs, researchers hope to gain insights into human aging as well.
Dogs share our environment and genetic diversity, making them valuable subjects for understanding the aging process.
Caloric Restriction and Obesity
The question of whether caloric restriction extends lifespan solely by preventing obesity is valid.
However, obesity is associated with accelerated aging due to factors such as inflammation, hormonal signals from adipose tissue, and the physical impact of gravity on the body.
Caloric restriction can have multiple benefits beyond weight management.
Understanding the Microbiome
The microbiome plays a role in adjusting food cravings and potentially impacting weight set points.
The diet we consume can remodel the microbiome and send signals throughout the body, including the brain.
The microbiome also interacts with the immune system, leading to changes in immune function due to low-quality diets.
