Rejuvenating 2.5 Years Without Surgery: The New Breakthrough Transforming Longevity

A new clinical trial published in Nature Communications is generating major excitement in the field of longevity. Researchers have found that a simple 5-day-per-month nutrition protocol, repeated for three cycles, can reduce biological age by approximately 2.5 years, while improving several key metabolic markers essential for healthy aging.

The study evaluated the effects of the Fasting Mimicking Diet (FMD), a structured nutritional plan designed to activate the same cellular mechanisms triggered by strict fasting—without having to stop eating. For those 5 days, the diet is low in calories, protein and carbohydrates, and rich in plant-based healthy fats. During the remaining 25 days of the month, participants follow a normal Mediterranean-style diet.

A set of results that is impressing longevity experts

After only three cycles, participants showed:

• A reduction of ~2.5 years in biological age, measured using advanced epigenetic clocks

• Lower insulin resistance, essential to preventing diabetes and metabolic decline

• Less liver fat, one of the most common signs of aging metabolism

• Indicators of a more rejuvenated immune system, with improved functional responsiveness

For people over 50, these findings open the door to short, accessible interventions with vast potential to preserve long-term health.

Why is the Fasting Mimicking Diet so special?

Unlike total fasting, this method allows small amounts of plant-based foods while activating powerful processes such as:

• Autophagy, the body’s natural cellular clean-up

• Tissue regeneration, especially in the immune system

• Metabolic optimization, supporting stable energy, weight control, and cardiovascular protection

Its appeal is enormous: the protocol requires no permanent lifestyle change—only 5 days a month.

Important: this protocol is not for everyone

Although results are promising, the researchers emphasize that this approach should be done under supervision, especially for individuals with:

• Diabetes

• Chronic medication

• Cardiovascular conditions

• A history of eating disorders

Longevity science is advancing quickly, but it must always be practiced responsibly.

A new horizon for those who want to live long with full vitality

For people aged 50 and above, this type of intervention offers a powerful tool to maintain energy, mental clarity, strength, and overall well-being through short routines supported by scientific evidence.

The message is clear: chronological age moves forward, but biological age can indeed stay younger through smart, sustainable habits.
