Why Fasting and Photobiomodulation Are the Perfect Pair for Longevity

Fasting, while often viewed as a modern health trend, is an ancient practice with remarkable benefits for health, well-being, and longevity. It requires no expensive gadgets or restrictive diets—just dedication and consistency. However, like any powerful biohacking tool, fasting can be enhanced when combined with complementary methods. Enter photobiomodulation (PBM): a cutting-edge technology that amplifies fasting’s benefits, keeps you motivated, and energizes you through its unique properties.

What Is Fasting?

Fasting is the deliberate abstention from food or drink for a specific period. This can range from intermittent fasting (shorter cycles) to prolonged fasting (lasting days). Fasting triggers profound changes in the body, forcing cells to adopt survival mechanisms like detoxification, repair, and fat utilization. These processes, often dormant due to continuous eating, promote metabolic health, longevity, and disease resistance. (1)

What Happens to the Body During Fasting?

Fasting sets off a cascade of metabolic and cellular processes:

12–18 Hours:
- Fat Burning Begins: Insulin levels drop, and the body starts burning stored glucose (glycogen).
- Hormonal Changes: Leptin (fullness hormone) decreases, while ghrelin (hunger hormone) rises, signaling the brain that it’s time to eat. (3)
18–24 Hours:
- Ketosis Kicks In: With glycogen depleted, the body burns fat for energy via lipolysis. Amino acids are also utilized for energy production.
- Glucagon Increases: Prevents blood sugar levels from dropping too low. (4)
24–48 Hours:
- Autophagy Begins: Cells clean out damaged components, repairing themselves and enhancing efficiency. This natural process declines with age, making fasting a powerful tool for longevity. (5)
48–54 Hours:
- HGH Surges: Human growth hormone rises, aiding muscle repair and preservation. Inflammation decreases significantly. (6)
54–72 Hours:
- Insulin Sensitivity Peaks: Insulin levels reach their lowest point, reducing inflammation and enhancing autophagy. (7)
72+ Hours:
- Immune System Renewal: Stem cell production ramps up, refreshing immune cells and reducing oxidative stress. (8)

The Benefits of Fasting

Fasting offers a wide array of health benefits:

Boosts cognitive performance
Reduces inflammation
Enhances fitness and physical performance
Supports weight management
Extends healthspan and lifespan
Improves heart health

While fasting is generally safe, consult a healthcare provider if you have underlying conditions or specific health concerns. (10), (11)

Pairing Fasting with Photobiomodulation

Combining fasting with photobiomodulation (PBM) maximizes the health benefits of both practices. Here’s how red light therapy amplifies fasting’s effects:

Enhanced Cellular Hydration:
PBM stimulates ATP production in the mitochondria, which produces endogenous water as a byproduct. This additional hydration is especially beneficial during fasting, when water intake may decrease. (21), (22)
Improved Blood Circulation:
Red and near-infrared light increase blood flow by dilating blood vessels. This accelerates detoxification, complementing fasting’s cleansing effects. (24), (25)
Muscle Preservation:
PBM aids in muscle recovery and growth, offsetting potential muscle loss during fasting. Pairing PBM with a high-protein diet during eating phases ensures better muscle preservation. (26), (27)
Increased Energy:
Fatigue is common during fasting as the body adjusts to using stored energy. PBM recharges cellular energy, boosting overall vitality and motivation. (28), (29)
Better Sleep:
PBM enhances melatonin production, promoting deeper, more restorative sleep. This is crucial during fasting, when the body undergoes repair and recovery. (31), (32)
Mood Regulation:
PBM stimulates the production of mood-enhancing hormones, reducing irritability and mood swings often associated with fasting. (33), (34)

Considerations for Combining Fasting and PBM

While fasting and PBM together offer incredible benefits, it’s essential to avoid overlapping their side effects. Fasting can cause brain fog and mild headaches, especially during the adjustment period. Similarly, overexposure to PBM may result in temporary lightheadedness. To mitigate this:

Start Slow: Use lower PBM intensities during fasting’s early stages.
Time Your Sessions: Schedule PBM sessions during eating windows or when energy dips.
Stay Hydrated: Ensure adequate fluid intake to prevent dehydration.

Conclusion

Fasting is a proven method to detoxify the body, enhance cellular function, and extend lifespan. When combined with photobiomodulation, these benefits are amplified, resulting in improved energy, better mood, and optimized cellular health.

By harnessing the synergy between fasting and PBM, you can achieve a holistic approach to health, well-being, and longevity. Ready to try this ultimate biohack? Dedicate yourself to consistent practice, and let your body and mind reap the rewards.
