Centenarian nutrition expert reveals his 7 guidelines for prolonged, vigorous well-being

Dr. John Scharffenberg, a 101-year-old nutritionist and adjunct professor, has turned heads with his remarkable longevity. His secret? A set of seven key lifestyle habits that prioritise consistency, moderation, and evidence-based practices over extreme diets or fitness fads.

The Seven Habits

1. Intermittent Fasting: Skipping dinner allows Dr. Scharffenberg's body a longer rest period from digestion, supporting metabolism, insulin balance, and weight control. This practice is linked to better heart health, reduced inflammation, and improved longevity.
2. Moderate Physical Activity Through Meaningful Work: Instead of gym routines, Dr. Scharffenberg stays active by working on his forested property—clearing land, planting trees, and tending a large garden. This sustained physical effort supports metabolism and reduces age-related disease risks.
3. A Plant-Based Diet: Following principles similar to the Seventh-day Adventist diet, Dr. Scharffenberg adopts a diet rich in plant-based foods, which is associated with longer life and is characteristic of the Blue Zones.
4. Avoiding Tobacco and Alcohol: Dr. Scharffenberg avoids substances like tobacco and alcohol, which have been debunked as beneficial despite past claims. Current research shows these can increase risks for cancer, liver disease, and cognitive decline.
5. Consistency Over Cycles: Dr. Scharffenberg maintains a gentle, steady rhythm in lifestyle habits without on-off or fad cycles, allowing his body the time needed to repair and maintain health over decades.
6. Active Engagement in Life and Learning: Dr. Scharffenberg continues to drive, lecture internationally, and run an educational channel (Viva Longevity), promoting ongoing intellectual and social engagement which is important for healthy aging.
7. Discipline and Simplicity: His lifestyle is grounded in deliberate simplicity and discipline rather than complexity, believing in small, steady changes over time to enhance health and longevity.

Bucking Conventional Wisdom

Unlike popular fitness trends, Dr. Scharffenberg emphasises sustained, purposeful physical work rather than structured gym workouts or exercise fads. Rather than relying on genetics or expensive treatments, he focuses on basic, evidence-based lifestyle choices practised consistently. He challenges long-held beliefs such as moderate alcohol consumption being heart-healthy, aligning instead with newer evidence discouraging even moderate drinking. His lifestyle is an embodiment of long-term habits rather than short-term diets or intermittent on-off health routines.

In summary, Dr. Scharffenberg’s longevity secrets combine intermittent fasting, meaningful physical activity, plant-based eating, avoidance of harmful substances, and consistent, disciplined habits that foster metabolic health and bodily repair, setting his approach apart from more conventional or fad-based longevity advice.
