If you came to this article, you’re probably one of the thousands of women who have heard about the benefits of Intermittent Fasting but would like to know first: is Intermittent Fasting safe for Women?
The short answer: yes, but it depends.
It is certainly safe in some cases, but there are times where women should not fast or do it very carefully.
With so many benefits like weight loss, the boost in energy levels, improved overall health and well being, trying out Intermittent Fasting for women sounds like a no-brainer, right?
But, it is always important to do your research before diving into a new diet or lifestyle regime. In this article, we’ll guide you through everything you need to know when it comes to Intermittent Fasting for women.
While we can all agree that women are strong, powerful…and can be just as capable of fighting hunger as men, there are a few differences in our bodies that are important to take into account.
We have looked at the available research and tried to find answers to the below questions, so that you can make an informed decision regarding intermittent fasting.
Feel free to jump straight into the following sections if you will:
First, let’s have a look at Intermittent Fasting benefits for women. Generally, there is not much difference between the two genders: men and women.
Here are the 3 most common results you can expect after starting intermittent fasting for any gender.
Losing unwanted pounds is the main motivation for most people to start Intermittent Fasting. Studies show that intermittent fasting indeed can be just as effective weight loss strategy as traditional calorie-restricted diets.
The amount of weight you will lose, however, is highly impacted by the number of calories you consume during the eating window and how long you stick to the lifestyle.
For our article on What Intermittent Results Can You Expect we surveyed over 40 people and could conclude that women lose weight as effectively as men.
Yet, men reach slightly higher results in a shorter time: while the majority of our surveyed men (53%) lost 7-13 pounds (3.2-6 kg) in the first month, the majority of women (40%) lost up to 7pound (3kg). See more details in our article here.
Heart diseases are the leading cause of death worldwide.
Good news for Intermittent Fasters – risk factors of various heart conditions can be lowered with the help of Intermittent Fasting. For example, studies show that Intermittent Fasting can lower blood pressure and cholesterol levels.
Also, let’s not forget about the aforementioned weight loss. Obesity is a strong risk factor for the development of heart diseases and intermittent fasting is a great way to shred some of that unwanted fat.
Intermittent fasting is a popular tool to increase energy levels and improve focus.
Check out our article How to do Intermittent Fasting According to 40 Famous People and you will be surprised by some of the benefits celebrities claim to experience. For example, “Coldplay” soloist Chris Martin swears Intermittent Fasting makes him sing better.
Intermittent fasting can do miracles to our mental health, too.
There’s a study finding that eight weeks of intermittent fasting improved body image in obese adults, decreased depression and even binge eating behavior.
Yet, there are certain things when it comes to Intermittent Fasting for women worth highlighting.
Our reproductive system is very different from that of men and hence women should pay closer attention to their hormones when doing Intermittent Fasting.
The female brain and ovaries communicate through the so-called hypothalamic-pituitary-gonadal (HPG) axis. While it might sound very complicated, in short, it regulates the brain signals to the ovaries to release the necessary amount of estrogen and progesterone hormones.
This happens on a very precise and regular cycle in women, and there can be many environmental factors that can affect this process. While for some women, their hormones and cycle are generally stable, many women are more sensitive to changes in their diet, lifestyle, stress or even the weather.
A sudden change to your eating schedule, in particular, fasting for prolonged periods, can put many women in stress and hence cause them to miss their period, throw off their cycle or even lead to infertility issues. Still, more studies need to be done to confirm this.
Knowing this, it is advised to ease into Intermittent Fasting, if you are a woman, to reduce stress on your body and slowly get used to the lifestyle change.
You might want to start with shorter fasting periods (e.g., 12/12) or have fewer fasting days a week instead of starting with 7 days straight Intermittent Fasting.
"Women tend to struggle during certain parts of their cycle when it comes to Intermittent Fasting. Fasting tends to be the easiest right before their menstrual cycle starts. It tends to be the most difficult during the menstrual cycle. Then the next 7 days normally are easy. So we go one week it's easy, one week it's challenging."

While there are not many studies on the effects of Intermittent Fasting on pregnancy, it is generally not recommended to practice Intermittent Fasting for women during pregnancy or breastfeeding.
Most existing studies look at pregnant women doing fasting during the Muslim holiday of Ramadan. It lasts about 30 days, during which people fast from dawn to sunset. While breastfeeding and pregnant women are allowed to quit fasting during Ramadan, some still decide to carry on with it.
The results of these studies showed that fasting didn’t impact the birth weight of the baby. However, researchers emphasize that more studies are needed to understand the possible long term effects completely.
Therefore, if you decide to start or carry on with intermittent fasting during pregnancy, you should always consult with your doctor.
Here are two main reasons why you should be cautious with Intermittent Fasting during pregnancy.
Same applies for any breastfeeding women, who normally need up to 500 extra calories a day, and a continuous source of fluids and calories to maintain milk supply and meet her own body’s needs.
Before we summarize the findings, let’s have a look at what other real-life women have to say about their Intermittent Fasting experience.
Below is just a small snapshot of all the women from our Intermittent Fasting community that are swearing Intermittent Fasting has changed their lives. To read more about their stories, head to What Intermittent Fasting Results Can You Expect.
Despite being slightly more sensitive to Intermittent Fasting than men, women can still practice time-restricted eating and experience all the intermittent fasting benefits, including weight loss.
However, there some important factors to take into account before you embark on the Intermittent Fasting journey.
With fewer hours to consume food, it is likely that you will be consuming fewer calories and as learned earlier, female bodies are more sensitive to caloric restriction.
Therefore it is important to take a more relaxed approach to intermittent fasting, start slow and listen to your body.
If you experience any of the severe side effects like a missed period or constant fatigue, take a break and consult with your doctor. A professional will be able to advise the best approach for your unique situation or recommend alternative means to reach your weight loss or diet goals.
Intermittent fasting should by no means be a way out of a bad diet.
Nutritional deficiencies when not getting enough macronutrients (carbs, protein and fats) or micronutrients (vitamins and minerals) are more common among women, particularly young women during childbearing age, and is linked with poor diet choices. Having a nutritious, balanced diet is the key when doing intermittent fasting to avoid most side effects of fasting.

Studies show that it is important to make a distinction between different body weights when looking at side effects and benefits of Intermittent Fasting.
Overweight and obese women show significant improvements with Intermittent Fasting. In contrast, women with normal weight did not experience the same across-the-board metabolic benefits.
Underweight women should be particularly careful when doing intermittent fasting. Even if you don’t need to lose weight, you can still enjoy other benefits of Fasting such as cell regeneration, improved energy levels and reduced blood sugar levels. But, it’s crucial to make sure you have a nutritious diet and sufficient caloric intake to avoid intermittent fasting side effects.
For a generally healthy person it is okay to start beginner-friendly intermittent fasting methods like intermittent fasting 16/8 on their own.
However, you should definitely consult with your doctor if you:
