Jason Fung’s The Hunger Code presents a provocative argument about food, hunger and body weight. Rather than viewing weight primarily as a simple matter of calories consumed and calories burned, Fung places considerable emphasis on insulin, hormones, hunger and the timing of eating.
Fasting is central to this argument. Fung suggests that periods without food can change the hormonal environment in the body and make it easier for the body to use stored energy. He also connects fasting with broader ideas about metabolic health and, ultimately, longevity.
For much of human history, the dream of living longer focused on adding years to life. Today, the conversation has shifted. The real goal is not merely lifespan, but healthspan—the number of years we remain physically active, mentally sharp, socially connected, and free from major disease.
As we move through 2026, the science of longevity continues to evolve. Yet amid the headlines about anti-aging drugs, genetic breakthroughs, and billion-dollar biotech companies, a surprising theme has emerged: many of the most effective ways to improve health and longevity are already within reach.
Natural Hygiene, Orthopathy, and the Timeless Wisdom of Fasting
When it comes to health, few movements have been as radical and enduring as Natural Hygiene. Rooted in the belief that the human body has an inherent ability to heal itself when given the right conditions, this philosophy emphasises simplicity, self-responsibility, and respect for nature’s laws. At its core sits Herbert M. Shelton (1895–1985), one of the most influential figures in modern natural healing.
How And When To Be Your Own Doctor (1996) This book was written after 25 years of clinical practice. Dr. Isabelle Moser was not a rigid, doctrinaire natural hygienist. She incorporated into her practice what she considered the most useful aspects of many disciplines, including vitamins and other food supplements, protomorphogens, massage, accupressure, colonics, dietary restriction, etc. Dr Moser practised during the late 20th century, and Steve Solomon, her husband, was a well-known writer and gardening expert. Together, they created a work that sits at the intersection of natural hygiene, self-reliance, and practical health wisdom. This isn’t a book about popping supplements or chasing the latest health trend. It’s about reclaiming responsibility for your body and your health, and it does so through some bold—and sometimes challenging—ideas, eg water fasting.
“Its a virtual certainty that to fully recover, a seriously ill person will have to significantly rebuild numerous organs. They have a hard choice: to accept a life of misery, one that the medical doctors with drugs and surgery may be able to prolong into an interminable hell on earth, or, spend several years working on really healing their body, rotating between water fasting, juice or broth fasting, extended periods on a cleansing raw food diet, and periods of no-cleansing on a more complete diet that includes moderate amounts of cooked vegetables…”
At a time when health advice comes packaged with supplements, subscriptions, and social media hype, it’s refreshing—almost rebellious—to turn back to someone like Upton Sinclair. He wasn’t a doctor. He wasn’t selling a program. He was simply a passionate truth-seeker who used extended fasting and plain food (especially beef) to transform his body and mind.
Sinclair’s approach is stark, raw, and astonishingly relevant—especially for those over 50 seeking simple, sustainable health with minimal expense.
Life is so fast now we don’t have to read a book from start to finish. We rush everywhere, binge watch TV, eat fast food and multitask our lives away. There are so many books out there and so little time. We have the Fear of Missing Out (FOMO) so now there are summaries of books we can read or listen to on any of our devices.
If you are unable to handle the Joy of Missing Out (JOMO) then here is a list of sites with book summaries. Of course it’s not the same as reading the book. Note that whomever wrote the summary is using what THEY think is important or key based on their life, their understanding, their upbringing and their teaching. Still its another way to learn new ideas and ripple your mind.
These are great for whatever device you use… I use a google chrome extension and send them to my kindle for reading later.
The Internet Archive, a 501(c)(3) non-profit, is building a digital library of Internet sites and other cultural artifacts in digital form. Like a paper library, we provide free access to researchers, historians, scholars, the print disabled, and the general public. Our mission is to provide Universal Access to All Knowledge.
We began in 1996 by archiving the Internet itself, a medium that was just beginning to grow in use. Like newspapers, the content published on the web was ephemeral – but unlike newspapers, no one was saving it. Today we have 20+ years of web history accessible through the Wayback Machine and we work with 450+ library and other partners through our Archive-It program to identify important web pages.
