So, why the confusion?
Let’s break down whether women should intermittent fast, and if so, how to do it healthfully.
Is intermittent fasting safe for women?
The term “stress” often comes with a negative connotation, but it’s not all bad.
If you’re managing your stress levels well, these practices prompt positive, healthy changes in your body.
However, if you’re over-stressed, your body may not be able to handle any additional stressors.
The bottom line is that every woman is different.
When kisspeptin is released, it activates a hormone calledgonadotropin-releasing hormone2, or GnRH.
LH also signals your ovaries to release an egg during the ovulation period of your cycle.
FSH stimulates the growth of follicles in the ovaries and also plays a role in estrogen production.
And in extreme cases, it could lead to fertility struggles.
Can fasting affect fertility?
Because fasting may negatively affect a woman’s hormones, there are related concerns about fertility.
Some medical experts think that a woman’s body may see fasting as a danger of impending starvation.
However, there are other doctors, likeFelice Gersh, M.D., who have opposing views.
So, who’s right?
In one study, researchers looked at how three months of intermittent fasting affected female rats.
LH and kisspeptin levels went down, while estradiol levels went up.
On the other hand, when insulin levels go down, it can improve ovarian function.
Intermittent fasting & your period
There’s also concern about whether you should fast during your period.
Shah explains that the week leading up to your period is when you’re most sensitive to extra stress.
You also become less sensitive to insulin.
These hormonal changes can slow down your metabolism, making you more prone to weight gain.
They can also cause other uncomfortable symptoms like mood changes, fatigue, brain fog, and psychological stress.
This brings up questions about whether peri- and postmenopausal women should take up fasting.
Of course, you don’t have to just take her word for it.
Research shows that intermittent fasting can helpimprove insulin sensitivity and promote fat loss9.
Some women, especially those under extreme stress, are more sensitive to potential negative hormonal changes when fasting.
On the other hand, there are some women who thrive withintermittent fasting.
If you feel great, you’re able to continue the course.
