For Women.
Important Note: Before starting any fasting regimen, please consult with your healthcare provider, especially if you have any underlying health conditions or are taking medications.
Introduction
Water fasting has gained significant attention in the wellness and longevity communities, and for good reason. As someone who has extensively researched and experienced water fasting, I want to share a comprehensive guide specifically tailored for women interested in this transformative practice. A 24-72 hour water fast can be a powerful reset for your body and mind, but it requires proper understanding and preparation.
The Science Behind Water Fasting
Recent scientific research has revealed numerous benefits of water fasting:
Autophagy
- Research by Nobel Prize winner Yoshinori Ohsumi showed that fasting activates autophagy within 24-48 hours
- A 2019 study in Cell Research demonstrated increased autophagy markers after 48 hours of fasting
- The Journal of Cell Biology (2018) found that women may have enhanced autophagy responses compared to men
Metabolic Benefits
- Research published in Cell Metabolism (2019) showed a 58% improvement in insulin sensitivity after a 3-day fast
- The New England Journal of Medicine’s review (2020) linked fasting to improved metabolic syndrome markers
- A study in Nature Medicine found significant improvements in blood pressure after 72 hours of fasting
Longevity Markers
- Valter Longo’s research at USC showed fasting activates stem cell regeneration
- Studies in aging biomarkers show reduced inflammation markers (IL-6, CRP) after 72-hour fasts
- Research in Cell Stem Cell journal demonstrated enhanced immune system regeneration after 3-day fasts
Benefits Specific to Women
- Hormonal Balance: Fasting can help regulate hormones when done correctly
- Improved Insulin Sensitivity: Particularly beneficial for women with PCOS
- Enhanced Mental Clarity: Many women report improved focus and cognitive function
- Skin Health: Autophagy can contribute to better skin appearance
- Weight Management: Can help break through plateaus and reset eating patterns
Special Considerations for Women
Women’s bodies are more sensitive to extreme dietary changes due to our complex hormonal systems. Here are important factors to consider:
- Timing with Menstrual Cycle
- Best time: During the follicular phase (days 5-14 of your cycle)
- Avoid during: Menstruation and late luteal phase
- Why: Hormonal fluctuations affect fasting tolerance
- Pregnancy and Breastfeeding
2. Pregnancy and Breastfeeding
- Do not fast if pregnant or breastfeeding
- Wait at least 6 months post-pregnancy before considering fasting
- Consult with healthcare providers about timing
Hormonal Considerations
Estrogen and Fasting
- Estrogen levels can affect fasting tolerance
- Best timing: Days 5-12 of menstrual cycle
- Monitoring points:
- Energy levels
- Mood changes
- Sleep quality
- Temperature regulation
Thyroid Function
- Monitor T3, T4 levels if possible
- Short fasts may temporarily lower T3
- Recovery period important
- Supplements to consider:
- Iodine-rich foods post-fast
- Selenium-rich foods
- Zinc support
Strategies during a fast when hunger strikes:
- Meditation
- Light yoga
- Nature walks
- Sleep optimization
- Put phone away in a different room
- No blue light 1 hour before bed
- Take a late afternoon walk to sync your circadian rhythm
- Drink soothing tea
- Dim lights as the sun goes down
- Movement of any kind
- 10 bodyweight squats every 45 minutes
- Stretching
- 2-minute dance
- Relaxation
- Legs up the wall
- Skincare routine
- Bath
- Reading
How to Prepare for Your 24-72 Hour Water Fast
One Week Before

Conclusion
A 24-72 hour water fast can be a transformative experience when approached mindfully and with proper preparation. As women, our bodies require special consideration and care during fasting. Listen to your body, start slowly, and remember that fasting is a practice that improves with experience.
Remember to approach fasting as part of a broader healthy lifestyle rather than a quick fix. The benefits of water fasting extend far beyond the fasting period itself, potentially contributing to increased longevity and improved overall health.
Your first fast may not be perfect, and that’s okay. Each fasting experience is an opportunity to learn more about your body and its needs. Start with proper preparation, maintain awareness throughout the process, and break your fast mindfully to maximize the benefits of this powerful health practice.
