Fasting & Cellular Health Hub
Fasting & Cellular Health Hub
Fasting is one of the most powerful tools in integrative medicine — not just for weight loss, but for deep cellular renewal, longevity, and disease prevention. This hub brings together our complete library of evidence-based guides on autophagy, senolytic protocols, NAD+ biology, fasting modalities, metabolic health, and more.

The Healing Power of Fasting: A Complete Guide to Intermittent, Extended & Dry Fasting
The definitive overview — covering all major fasting modalities, mechanisms of cellular renewal, metabolic health benefits, and protocols for chronic illness. Start here if you're new to fasting science.
Category 1: Cellular Mechanisms & Longevity Science
Autophagy Deep Dive: How Your Cells Self-Clean and Why It Matters
The science of cellular autophagy — how fasting triggers your body's built-in recycling system to clear damaged proteins and organelles.
The mTOR Pathway: Why Turning It Off Periodically May Save Your Life
How mTOR suppression during fasting activates longevity pathways, reduces cancer risk, and promotes cellular quality control.
Mitophagy: How Fasting Clears Damaged Mitochondria and Renews Cellular Energy
The selective autophagy of dysfunctional mitochondria — and why it's essential for sustained energy, metabolic health, and longevity.
Senolytic Protocols: Clearing Zombie Cells for Longevity
How senescent cells accumulate with age, drive chronic inflammation via SASP, and how senolytics — including fasting, quercetin, and fisetin — selectively eliminate them.
NAD+, NMN & Sirtuins: The Longevity Molecule Explained
Why NAD+ declines with age, how sirtuins depend on it, and evidence-based strategies — including fasting, NMN, and NR — to restore cellular energy and longevity signaling.
Category 2: Fasting Modalities & Protocols
Intermittent Fasting (16:8, 18:6, OMAD): A Complete Beginner's Guide
The most accessible entry point to fasting — how to structure your eating window, what to expect, and how to optimize results.
The 5:2 Protocol: How to Fast Two Days a Week for Maximum Benefit
A flexible approach to weekly fasting — the science, the structure, and who benefits most from the 5:2 method.
Extended Water Fasting: What to Expect on Days 1–7
A day-by-day guide to extended water fasting — physiological changes, electrolyte management, and safety considerations.
The 5-Day Fasting-Mimicking Diet: A Complete Step-by-Step Protocol
Dr. Valter Longo's clinically validated FMD protocol — how to get the benefits of extended fasting while still eating.
Dry Fasting Safely: Protocols, Risks, and the Filonov Method
The most advanced fasting modality — mechanisms, risks, the Filonov protocol, and who should and shouldn't attempt dry fasting.
Breaking a Fast the Right Way: The Science of Refeeding
How you break a fast matters as much as the fast itself — refeeding protocols, foods to prioritize, and mistakes to avoid.
Category 3: Metabolic Health & Fuel
Metabolic Flexibility: How to Train Your Body to Burn Both Fat and Glucose
Why the ability to switch between fuel sources is a hallmark of metabolic health — and how fasting builds this capacity.
Ketones as Medicine: The Therapeutic Power of Beta-Hydroxybutyrate
BHB is more than a fuel source — it's a signaling molecule with anti-inflammatory, neuroprotective, and longevity-promoting properties.
Fasting and Type 2 Diabetes: Reversing Insulin Resistance at the Root
How fasting addresses the root cause of type 2 diabetes — insulin resistance — through metabolic reset and pancreatic beta cell recovery.
Category 4: Fasting & Disease
Fasting and Autoimmune Disease: Immune Reset, Gut Permeability & the Longo Protocol
How fasting modulates immune function, reduces autoimmune flares, and supports gut barrier repair in autoimmune conditions.
Fasting and Neurological Disease: BDNF, Ketone Neuroprotection & Brain Regeneration
The neuroprotective mechanisms of fasting — BDNF upregulation, ketone fuel for neurons, and applications in neurodegeneration.
Fasting and Cancer: How Metabolic Deprivation Starves Tumors and Supports Healing
Differential stress resistance, fasting-mimicking diet in oncology, and the emerging evidence for fasting as a cancer adjunct therapy.
Fasting and Cardiovascular Disease: A Comprehensive Guide to Heart Health
How fasting improves lipid profiles, reduces arterial inflammation, lowers blood pressure, and supports cardiovascular resilience.
Fasting and Gut Health: Microbiome Reset, Intestinal Repair & the MMC
How fasting activates the migrating motor complex, resets the gut microbiome, and supports intestinal barrier repair.
Category 5: Lifestyle Stacking
Fasting and Circadian Rhythm: Why When You Eat Matters as Much as What You Eat
Time-restricted eating aligned with circadian biology — how meal timing affects metabolism, sleep, hormones, and longevity.

Heat stress + fasting as a synergistic protocol for autophagy induction, heat shock protein activation, and cellular detoxification.
Category 6: Special Populations
Women and Fasting: Hormonal Considerations and Cycle Syncing
Why women need a different approach to fasting — hormonal sensitivity, cycle-synced protocols, and how to fast without disrupting the HPA axis.
Fasting After 50: Benefits, Risks, and Modified Protocols
How fasting needs change with age — muscle preservation, bone density, hormonal shifts, and safe modified protocols for older adults.
Fasting and Athletes: Performance, Recovery, and Muscle Preservation
How athletes can leverage fasting for metabolic adaptation, recovery, and body composition without sacrificing performance or lean mass.
