🌕 Fasting and the Lunar Cycle: Is There a Connection?

By Manoj at UKFitClub | Longevity-Focused Training & Coaching for Over 40s

Could the Moon Affect Your Body — and Your Fast?

At UKFitClub, we’re known for taking a science-based yet open-minded approach to health and longevity. So when we hear questions like:

“Does the moon affect the body since we’re mostly made of water? “Is there any benefit to fasting during certain moon phases?”

....I think they’re worth exploring — especially when you consider that many over 40s are seeking a more natural, proactive rhythm to their health and training.

In this blog, we’ll explore the science, theory, and practical wisdom behind the potential link between fasting, lunar cycles, and body chemistry.

1. The Human Body: Mostly Water — Like the Earth

It’s a fact: the human body is made up of about 60–70% water, depending on age, sex, and muscle mass.

The moon’s gravitational pull influences the oceans, causing the daily high and low tides — so the idea that it could also affect the fluids and rhythms inside us isn’t far-fetched.

📚 A study published in Current Biology (2013) found that melatonin production and sleep patterns were disrupted during the full moon — even when people were in complete darkness, isolated from any visual cues. This suggests a biological sensitivity to the lunar cycle.

🌕 2. Ancient Cultures Fasted with the Moon

Long before modern science, ancient civilizations aligned fasting and cleansing practices with the lunar cycle:

• 🌑 New Moon: Often a time of detox, reflection, and “light eating”

• 🌕 Full Moon: Symbolised release, heightened emotional energy, and occasional fasting

• 🌓 Quarter Moons: Seen as transition points for setting or adjusting health routines

In Ayurvedic medicine, Yogic science, and Buddhist practices, moon-aligned fasting was said to:

• Improve digestion

• Support mental clarity

• Sync hormonal rhythms

While these traditions lacked modern data, their longevity across thousands of years is noteworthy — and increasingly being re-examined in the wellness world today.

3. The Science of Fasting, Hormones & Biorhythms

Modern intermittent fasting improves:

• Insulin sensitivity

• Hormonal balance (GH, cortisol, leptin)

• Autophagy (cellular repair)

• Circadian rhythm regulation

These same processes may be influenced by lunar changes:

• Melatonin and serotonin levels can shift during the moon phases

• Women’s menstrual cycles often align with the moon (roughly 28 days)

• Some research even suggests increased hospital admissions, sleep issues, and mood disturbances during full moons

Fasting enhances the body’s ability to:

• Regulate fluid balance (via kidney and electrolyte control)

• Rebalance stress and sleep hormones

• Activate natural repair systems during low-energy phases, such as the new moon

🌗 4. How to Align Fasting With the Moon Cycle (Practically)

Here’s a simple framework to experiment with moon-aligned fasting, especially if you're over 40 and want to be proactive about your health:

🌟 Pro Tip: Use the lunar cycle as a rhythm guide, not a strict rule. The goal is greater awareness, not rigidity.

Does the Moon Cause Fasting to Work Better?

Not directly — but it may enhance your ability to tune into your body.

If you’re someone who:

• Feels more energetic or emotional during full moons

• Has disrupted sleep during certain phases

• Feels better eating lighter at specific times of the month

…then lunar-aligned fasting could be a tool to improve regulation, lower inflammation, and restore mind-body awareness.

Pair it with:

• Strength training to preserve muscle

• Hydration and electrolytes to balance fluids

• Protein-rich eating windows to support recovery

Final Thought

We live in a world where most people are reactive, not proactive.They wait for pain, burnout, or decline before they act.

Tuning into natural rhythms — whether through fasting, strength training, or even lunar awareness — is a powerful way to become more in tune, self-reliant, and resilient.

So yes — the moon may be pulling more than just tides. It might just be pulling you toward deeper health awareness.
