Summary:
– Humans have practiced fasting for centuries, now gaining recognition for its health benefits.
– Valter Longo, a renowned expert in the field, has conducted extensive research on fasting and its effects on biology and longevity.
– Fasting triggers a cellular response that promotes autophagy, a process crucial for cellular regeneration and detoxification.
– Fasting can improve insulin sensitivity, reduce inflammation, and help prevent metabolic diseases.
– Longo’s groundbreaking work has shown that a fasting-mimicking diet can provide similar benefits to traditional fasting, making it more accessible and sustainable for many.
Fasting may seem strange or even extreme in our modern world, filled with processed foods and sedentary lifestyles. However, fasting has been a part of human history and culture for centuries, with religious and spiritual practices often incorporating periods of abstinence from food. Scientific research is shedding light on the fascinating biological mechanisms behind fasting and its potential to help us live longer, healthier lives.
One prominent figure in this field is Valter Longo, a renowned scientist and expert in diet, nutrition, metabolic disease, and insulin sensitivity. Longo’s work has revolutionized our understanding of fasting and its impact on biology. Through his research, he has uncovered the unique ways fasting can reset our biology and offer many health benefits.
One of the critical effects of fasting is its ability to trigger a cellular response known as autophagy. Autophagy is when cells break down and recycle damaged components, providing raw materials for cellular regeneration and repair. This natural detoxification process is crucial for maintaining healthy cells and preventing the accumulation of harmful substances. Fasting has been shown to enhance autophagy, allowing the body to cleanse and rejuvenate itself at a cellular level.
But what about the long-term effects of fasting on our health? Longo’s research has revealed many benefits that extend far beyond autophagy. One remarkable finding is the improvement in insulin sensitivity through fasting. Insulin is a hormone responsible for regulating blood sugar levels, and when cells become resistant to its effects, it can lead to various metabolic disorders such as type 2 diabetes. Fasting has been shown to enhance insulin sensitivity, allowing the body to effectively process glucose and maintain stable blood sugar levels.
In addition to its impact on insulin sensitivity, fasting has been linked to reducing inflammation, a key driver of many chronic diseases. Inflammation is the body’s immune response to injury or infection. Still, it can contribute to developing conditions such as cardiovascular disease, cancer, and neurodegenerative disorders when it becomes chronic. Fasting has been shown to modulate the inflammatory response, leading to a decrease in pro-inflammatory markers and an overall reduction in chronic inflammation.
While traditional fasting can pose challenges and may not be suitable for everyone, Longo has introduced a groundbreaking concept known as the fasting-mimicking diet (FMD). The FMD is a carefully designed nutritional plan that mimics the effects of fasting while still providing essential nutrients and calories. This approach allows individuals to experience the benefits of fasting without the difficulties associated with prolonged food restriction.
Longo’s research has shown that FMD can induce many of the same health benefits as traditional fasting, including improved insulin sensitivity, reduced inflammation, and even the promotion of healthy aging. FMD involves following a specific diet for a set number of days, usually around five days per month, which triggers the body’s fasting response without complete food deprivation.
The FMD has gained significant attention for its potential in preventing or managing metabolic diseases, such as type 2 diabetes and obesity. By optimizing the body’s metabolic state and promoting the utilization of stored fat for energy, FMD can help individuals achieve and maintain a healthy weight while improving overall metabolic health.
Furthermore, Longo’s research has also explored the effects of FMD on cancer patients undergoing chemotherapy. Fasting and FMD have been shown to protect healthy cells from the harmful side effects of chemotherapy while making cancer cells more susceptible to treatment. This groundbreaking discovery opens new avenues for integrating fasting and FMD into cancer treatment protocols, potentially enhancing the effects of therapies and improving patient outcomes.
In conclusion, the work of Valter Longo has demonstrated that fasting can reset our biology and provide numerous health benefits. From triggering autophagy for cellular rejuvenation and detoxification to improving insulin sensitivity, reducing inflammation, and even enhancing cancer treatment outcomes, the impact of fasting on our biology is genuinely remarkable. With the introduction of the fasting-mimicking diet, fasting has become more accessible and sustainable for individuals looking to optimize their health and increase their longevity. So, why not explore the potential of fasting and FMD to reset your biology and embark on a path toward better health and longevity?

Bulletproof Radio episode #812
What to know about fasting, body systems, and the future of longevity from the godfather of fasting research.
In this episode of Bulletproof Radio, I’m talking with a godfather of fasting, Professor Valter Longo, Ph.D. He started researching fasting decades before anyone else started paying much attention to it. In 2018, TIME Magazine named Prof. Longo as one of the 50 most influential people in health care for his research on fasting-mimicking diets to improve health and prevent disease.
He’s the director of the Longevity Institute at the University of Southern California-Leonard Davis School of Gerontology, Los Angeles, and director of the Longevity and Cancer Program at the Italian Foundation of Cancer Research.
“Fasting, in my mind, is probably the most powerful way to reset and help regenerate, but also help clear junk and accumulated damage,” Prof. Longo says.
Our conversation hits the high points of how and why too fast and also goes into the research that got us to what we know today and looks at what’s next. We talk about everything from Prof. Longo’s foundational research on yeast to the possibility of having future technology that tells us how to fast based on specific blood markers or gut bacteria.
He’s also focused on the nutrients in the fats, proteins and carbs we consume during our fasts.
“Without understanding how nutrients such as proteins and sugars affect cellular function, aging and aging damage, and regeneration, it’s difficult to determine the type and quantity of nutrients for optimal longevity,” Prof. Longo says in his book, “The Longevity Diet: Discover the New Science Behind Stem Cell Activation and Regeneration to Slow Aging, Fight Disease, and Optimize Weight.”
Beyond fasting, Prof. Longo created five pillars of longevity related to nutrition and human biology: Scientology (the study of youth), epidemiology, clinical studies, centenarian studies, and the study of complex systems.
We also discuss more significant philosophical questions and the ethics surrounding longevity. What would it mean to try and live forever? And what does longevity mean in the face of advancing technology that may boost our life span by 50 to 100 years?
“I think technology is going to take over in the next 50 years, and bionics is going to take over in the next 50 years,” Prof. Longo says. “It’s going to be a very different world; it’s going to be a very different approach. And it will be an approach that has to do much more with memory, memory transfer, and all kinds of crazy things.”
