Biological Age

  • Calendar age says little about actual health
  • Biological age is modifiable through lifestyle
  • Aging can be slowed and sometimes partly reversed
  • VO2max and muscle strength predict long health
  • Investing in lifestyle can make 5-15 years difference

Your calendar age says little about your actual health. Biological age reflects how well your cells, muscles and organs function.


Mitochondria are the energy plants of the cell. Their efficiency decreases with age, contributing to fatigue and muscle loss.

InterventionAdvice
Zone 2 endurance trainingDaily, 60-70% of maximum heart rate
Strength training2-3x per week for muscle mass and insulin sensitivity
Time-restricted eating16:8 or 18:6 to activate repair processes
NutritionProtein-rich, low-carb, fat-friendly

Chronic low-grade inflammation accelerates aging.

PillarAdvice
NutritionFatty fish, olive oil, walnuts, vegetables rich in antioxidants and polyphenols
Sleep7-9 hours, dark, cool, screen-free
StressReduce via breathing, meditation or nature exercise

Strong muscles and good endurance predict long health.

TrainingEffect
Strength trainingMaintain muscle mass
Endurance trainingImprove VO2max
Interval trainingCombine both effects
Balance and mobilityReduce fall risk

A stable blood sugar and healthy fat metabolism protect against age-related diseases.

AdviceExplanation
Unprocessed eatingFiber-rich and moderate in carbohydrates
AvoidSugars, alcohol, ultra-processed food
ConsiderBerberine or metformin for impaired glucose regulation (under medical guidance)

MomentAdvice
MorningDaylight, exercise, possibly fasted walking or training
Eating windowPreferably 12:00-20:00, two complete meals with vegetables, protein and healthy fats
EveningRest, few screens, magnesium glycinate 400 mg before sleep

Veelgestelde vragen

What is biological age?

Biological age reflects how well your cells, muscles and organs function - as opposed to your calendar age. This age is modifiable: through lifestyle adjustments, aging can be slowed and sometimes partly reversed.

How can I lower my biological age?

By investing in diet, exercise, sleep, stress balance and social connection, you can lower your biological age by 5 to 15 years. Focus on zone 2 endurance training, strength training, time-restricted eating and anti-inflammatory nutrition.

Which markers measure biological age?

Important markers are: fasting glucose (<5.0 mmol/L), HbA1c (<37 mmol/mol), fasting insulin (<5 mIU/L), TG/HDL ratio (<1.5), CRP (<1.0 mg/L), vitamin D (75-150 nmol/L), and functional parameters such as VO2max and grip strength.

Why is VO2max important for age?

VO2max (maximum oxygen uptake) is the strongest predictor of overall mortality and resilience. A higher VO2max means a younger biological age. It is trainable through endurance and interval training.
