Fasting & Nutrition Protocols for Longevity & Disease Prevention w/ Valter Longo | Rich Roll

The average 45 year old has 2 chronic conditions in the US. Sometimes people must take medications in order to stay alive, but we must start thinking more long term when implementing strategies to combat metabolic diseases, instead of always placing a bandaid on the issue.

Welcome to a deep dive into the science of living longer and healthier. Recently, longevity expert Dr. Valter Longo sat down with Rich Roll to unpack decades of research on fasting, diet, and disease prevention. If you are confused by the endless, contradictory dietary trends out there, Dr. Longo offers a "multi-pillar" approach based on basic science, epidemiology, clinical trials, and centenarian studies to cut through the noise.

Here are the core principles of Dr. Longo’s research on how to eat and fast for a longer, healthier life.

1. Embrace the "Longevity Diet" (Yes, It Includes Carbs)

Instead of fearing carbohydrates, Dr. Longo advocates for a diet where 50% to 60% of your calories come from whole, complex carbs. This does not mean eating refined sugars or excess pasta; it means prioritizing foods like legumes and whole-grain cereals, which meta-analyses link directly to increased life expectancy. Combine this with healthy fats from olive oil and nuts, which studies consistently show are better for cardiovascular health and longevity than low-fat diets.

2. The Age-Specific Protein Rule

One of the most surprising takeaways from Dr. Longo's research is that for individuals under the age of 65, a low-protein diet is optimal. He recommends consuming around 0.35 grams of predominantly plant-based protein per pound of body weight. Consuming excess protein activates growth pathways in the body, such as mTOR and IGF-1, which accelerate the aging process and dramatically increase the risk of cancer mortality.

However, the biological rules flip after age 65. Because the aging body's ability to process amino acids declines, older adults must moderately increase their protein intake—incorporating more vegetarian sources, eggs, or cheese—to prevent frailty, bone fractures, and muscle loss.

3. Stick to a 12-Hour Daily Fast

While 16-hour fasts (16/8) and skipping breakfast are massively popular right now, Dr. Longo strongly warns against them. He points to meta-analyses showing that skipping breakfast is actually associated with increased mortality and cardiovascular disease. Instead, he advocates for a simple, safe, and highly effective 12-hour daily fasting window.

4. The Fasting Mimicking Diet (FMD)

Thousands of years ago, human bodies evolved to store fat and become insulin resistant during the summer to survive the famine of winter. Today, because food is always available, the "winter never comes," leaving most people in a constant, unhealthy state of insulin resistance.

To simulate this missing "winter" without the dangers of extreme starvation, Dr. Longo developed the Fasting Mimicking Diet (FMD). This is a 4-to-7-day dietary protocol—typically done three to four times a year—that tricks the body into a fasted state while still providing specific nutrients. Clinical trials show that the FMD lowers pro-aging factors like IGF-1 and leptin for months, shifts the body into an insulin-sensitive fat-burning mode, and preserves lean muscle mass.

5. Reimagining "Food As Medicine"

Ultimately, Dr. Longo believes modern medicine relies too heavily on putting a "band-aid" on chronic diseases, cascading from one pharmaceutical drug to the next. He envisions a future healthcare system that utilizes dedicated teams—including physicians, dietitians, molecular biologists, and psychologists—to prescribe precise nutritional interventions that repair bodily systems and reverse diseases at their root.
