Dry fasting is amazing if you have any kind of issues with your period. I used to have very heavy periods since adolescence and the only times they were normal or even low, were mostly on dry fasts. I used to have very random cycles too, not having my period for months and then having my period for several weeks without end.
For a time I was actually dry fasting each time my period would start just to not have to deal with the heavy bleeding. I honestly would barely bleed when dry fasting.
When I stick to a low-carb, carnivore diet, it’s also pretty good. But dry fasting makes it almost unnoticeable.
You really should give it a try.
Long term if you do want to have kids, you should go low-carb.
I have PCOS and I have had issues with actually being fertile for several years. Again, the only times I was doing good was during fasts or eating healthily ( carnivore or low-carb ).
You should check this video, it really explains what is going on with our bodies and why we end up with those specific struggles:
Hope it helps.
In combination with dry fasting, you should try an elimination diet.
I’m partial to Carnivore, but I think other people have claimed success going vegetarian or vegan.
But from carnivore, you can find testimonials on period-related pain on ZeroCarbZen.com and MeatHeals.com
