CAN FASTING AND EXERCISING CONTRIBUTE TO A LONGER LIFE?
Yes, fasting and exercising can contribute to
a longer, healthier life. Research suggests that both practices activate
biological pathways linked to longevity. Here’s how they work:
Fasting and
Longevity
Fasting—especially intermittent fasting (IF)
and caloric restriction—triggers processes that may extend lifespan:
- Autophagy: The
body removes damaged cells and regenerates healthier ones, reducing the
risk of age-related diseases.
- Improved Insulin Sensitivity:
Fasting helps regulate blood sugar, lowering the risk of diabetes.
- Reduced Inflammation:
Chronic inflammation accelerates aging; fasting can lower inflammatory
markers.
- Increased Cellular Stress Resistance: Fasting induces mild stress that strengthens cells, making them
more resilient.
- Activation of Longevity Genes: It
influences sirtuins and AMPK pathways, associated with extended lifespan
in animal studies.
Exercise
and Longevity
Regular physical activity has strong links to
increased lifespan through several mechanisms:
- Cardiovascular Health:
Strengthens the heart, lowers blood pressure, and reduces the risk of
heart disease.
- Muscle Preservation: Helps
maintain muscle mass, preventing frailty and age-related decline.
- Enhanced Mitochondrial Function:
Boosts energy production and reduces oxidative stress.
- Brain Health:
Reduces the risk of neurodegenerative diseases like Alzheimer's.
- Anti-Inflammatory Effects: Like
fasting, exercise helps control inflammation.
When combined, fasting and exercise may have synergistic
benefits, enhancing fat metabolism, improving endurance, and further
stimulating autophagy. However, balance is key—excessive fasting or
overtraining can have adverse effects.
