Why Even Think About Fasting During Your Period?
Let us start by addressing the most pressing issue: Is it appropriate to fast during menstruation? We typically think of fasting in terms of weight loss detoxification or gut rest. But what if I told you that the benefits of fasting while on period go beyond that?
I’m talking about fewer cramps, mood swings and bloating as well as a stronger bond with your body. It all depends on how and when you fast though. I’m not advocating extremes or starving myself I assure you. I’m here to share how gentle mindful fasting techniques such as intermittent fasting have made it easier for me to get through my period than I ever imagined.
1. Less Pain, Fewer Cramps
I started by noticing that my cramps were much less severe. Fasting can naturally lessen those intense menstrual pains by reducing inflammation in the body. I stopped reaching for painkillers as frequently even after a 14:10 routine.
2. More Focused and in a Calmer Mood
When I fast my mood swings and brain fog are much easier to handle. Even during the days of emotional upheaval I felt more mentally stable and clear-headed because ketones which are created during fasting fuel the brain more effectively.
3. Hormonal Balance
Unexpectedly I experienced fewer breakouts and a more regular cycle. I felt more in charge of my body and less like it was working against me because fasting improves insulin sensitivity and helps control estrogen.
4. Say Goodbye to Bloating
It’s so much better than that uncomfortable heavy bloat. During those slow bloated days fasting helped soothe my stomach because it allows the digestive system to rest. Even a brief period of fasting helped me feel less bloated.
5. Increased Energy Better Sleep
I slept better and woke up feeling more rested after fasting which is crazy but true. I was expecting to feel exhausted but I was pleasantly surprised. Even during my dreaded second day my energy was more consistent.
6. Support Natural Detox
The body already gets rid of waste when you have your period and fasting makes it even better. My liver could concentrate on detoxing if there were fewer meals for it to digest. I experienced fewer headaches, felt less hazy and even had clearer skin.
7. More Mindful Eating
During PMS I would overindulge in chips and sweets prior to fasting. However I was able to break that cycle by fasting. I was able to control my cravings and became more conscious of why I was eating. huge victory for the body and the mind.
8. Increases Autophagy to Aid in Cellular Repair
This one is significant but science-based. Your body uses autophagy which is triggered by fasting to eliminate aging damaged cells. The uterine lining is already being shed by your body during your period so this extra help can promote cellular renewal and general healing.
Is Fasting on Your Period Backed by Science?
Let’s discuss the facts because it is easier to trust a process when you know why it works. Your body is naturally more sensitive to insulin during your menstrual cycle particularly during the follicular phase (beginning on the first day of your period). As a result, you are better prepared to manage fasting during this phase and your blood sugar is more stable.
In moderation, intermittent fasting may help regulate reproductive hormones such as luteinizing hormone and estrogen according to a 2021 review published in Nutrients. Gentle fasting (such as 12:12 or 14:10) during your period can help your body reset without overtaxing it which is crucial because estrogen levels drop at the beginning of your cycle and rise again during ovulation.
Additionally autophagy—your body’s method of eliminating damaged cells—is triggered during a fast. Fasting provides your body with additional support during this reset phase as your period is already a natural detox.
Is It Safe to Fast While on Your Period?
That’s the big question isn’t it? Is it even acceptable to fast during my period?. The truth is that there are benefits of fasting while on period—but only if you are mindful about it. Don’t push yourself if your flow is extremely heavy or if you feel weak or lightheaded.
Always start by paying attention to your body. A modified fast such as a bone broth or tea fast works better for some women while a gentle 12- to 14-hour window is more effective for others. Hydration rest and maintaining awareness of your energy levels are crucial.
Most experts concur that for healthy women short-term intermittent fasting during menstruation is safe. Just make sure you’re eating wholesome meals during your windows of opportunity (consider foods high in iron healthy fats and plenty of water!).
Tips for Fasting Safely During Your Period
As we are discussing the benefits of fasting while on period, I’d like to share a few personal insights that have greatly facilitated the process.
- Start Slow: Take your time getting going. If you are new to fasting, start with 12:12 or even 10:14 instead of jumping straight into 16:8.
- Stay Hydrated: There is no way to change this. Fatigue and cramping will only worsen if you are dehydrated.
- Eat mindfully during eating windows: Choose meals that are rich in lean protein greens and healthy fats.
- Avoid intense workouts: During menstruation and fasting gentle yoga stretching or walking are ideal.
- Track your cycle: With each phase of your period observe how your body responds and modify your fasting windows accordingly.
With the help of these suggestions I was able to enjoy the benefits of fasting while on period without feeling exhausted or deprived.
What to Eat (and Why) When You’re Not Fasting
Just as important as your fasting window is when you eat. Pay attention to the following to maximize the benefits of fasting while on period.
- Foods high in iron include leafy greens, lentils, red meat (if you eat it) and pumpkin seeds.
- Magnesium: Aids in cramping foods that contain it include bananas, almonds and dark chocolate (yes really).
- Omega-3s: Walnuts, chia seeds and salmon can all help lower inflammation.
- Complex carbohydrates—sweet potatoes quinoa and brown rice—help maintain steady energy levels.
Eating more intelligently is what fasting is all about, not starvation. Believe me when I ate the appropriate foods during my eating windows the benefits of fasting while on period significantly increased.
