Intermittent fasting is becoming a popular strategy for weight loss, energy, mental clarity, and other benefits. The concept of intermittent fasting is clear. You consume all your calories quickly — say, between 12 and 6 p.m. — and then skip meals for the rest of the day.
While intermittent fasting is simple, the health advantages are surprisingly strong. Fasting improves insulin sensitivity, blood sugar levels, blood pressure, and other factors. Many people find that intermittent fasting makes calorie restriction simpler, which aids them in meeting their weight reduction objectives.
Fasting, however, is not for everyone, and some research suggests that intermittent fasting affects men and women differently. Some women may wish to change their fasting schedule to keep their hormones and reproductive health in check.
Here’s a quick overview of intermittent fasting for women, covering what it is, the advantages of intermittent fasting, and how you may modify intermittent fasting to match your body’s specific demands as a woman.
What is Intermittent Fasting?
It is simple to practice intermittent fasting. You set an eating window for yourself daily, from noon to 8 p.m. During that time, you consume all of your food for the day. Outside of that time, you have a fasting window in which you don’t eat anything (coffee, tea, etc. are OK).
In the preceding scenario, you have an eight-hour window to eat, leaving you with a 16-hour fast daily. That’s a typical fasting arrangement known as a 16:8 fast, but it’s crucial to realize that there are no complex fasting laws. You can adjust your fasting schedule to meet the demands of your body.
Some people fast by skipping breakfast a few times each week, while others practice strict alternate day fasting — an eating day followed by a fasting day — or fast for several days in a row. Others dislike fasting and avoid it entirely.
Your intermittent fasting schedule is entirely up to you; experiment to find what works best for you. For a more in-depth look at how intermittent fasting works, see this beginner’s guide to intermittent fasting.
But why would you want to fast in the first place?
The Health Benefits of Intermittent Fasting
Missing meals might be beneficial to your health. According to research, intermittent fasting may be helpful for:
Fat Loss
Many people discover that intermittent fasting helps them eat less. If you only eat one or two meals a day, you may make them prominent and filling while maintaining a calorie deficit, which is essential for shedding body fat.
Going to bed hungry is one of the most challenging aspects of dieting. With intermittent fasting, you may satisfy your appetite in the morning when your energy levels are high. Then, in the afternoon, you may eat till you’re full and sleep on a full stomach.
Fasting is an efficient technique to burn fat and lose weight as long as you establish a pattern that feels sustainable to you [1][2][3].
Anti-aging
Fasting promotes autophagy, which acts as a cell-cleaning process [4]. Fasting causes your cells to become more efficient, mending or replacing defective sections. As a result, there is less inflammation and more effective cellular activity throughout your body [5].
Mental clarity
Many people report a significant gain in mental function when they fast. While no human trials have been conducted, rat research discovered that “short-term fasting induces profound neuronal autophagy” [6]. People may see a comparable rise in brain autophagy, resulting in more efficient brain cell activity.
Decreased inflammation
A 2019 research looked at Ramadan fasters who fasted from dawn to sundown. Researchers discovered that following the fasting period, the subjects’ inflammatory indicators significantly decreased [7].
Fasting also works well with a keto or low-carb diet. Ketosis lowers hunger [8], making it easier to endure extended periods without eating.
Does Intermittent Fasting Affect Men and Women Differently?
While intermittent fasting benefits everyone, there are a few things that women should be aware of when fasting.
Hormones account for a large portion of the discrepancy. Women have far more hormonal fluctuation over a month, and fasting may be especially tough during specific stages of your cycle. Things to keep an eye out for include:
Loss of your period
When many women benefit from intermittent fasting, some may miss their period when fasting [9].
Low-calorie diets or lengthy periods without eating can reduce the production of two hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), both of which are necessary for period regulation [10][11].
If your LH and FSH levels go too low, you may have irregular periods, or your menstrual cycle may end ultimately.
If you start having problems with your menstrual cycle, fasting may not be your best option. Please give it a rest and focus on nutrient-dense whole foods and healthy fats. They’ll help your hormones and get you back on track.
It’s worth mentioning that hormonal imbalances can also occur due to persistent stress and overexercising [12].
Hunger and cravings
Many women experience significant food cravings during menstruation (the cycle’s luteal phase) [13]. As an intriguing side point, one research found that women desired chocolate more than anything else during menstruation [14]. You may burn up to 10% extra calories during your period, making you hungrier [15]. You may not want to add fasting to the mix with food cravings, increased hunger, and many other symptoms associated with menstruation — exhaustion, cramps, etc.
If you attempt intermittent fasting, keep track of how you feel at different cycle stages. You may always change your fasting schedule as needed.
Who Shouldn’t Try Intermittent Fasting?
While fasting benefits many individuals, it is not suitable for everyone. Similarly, there may be periods when you do not want to fast. Fasting may be a poor choice if the following apply to you.
Chronic stress
Fasting is both physically and mentally challenging. When you’re healthy, that’s not a terrible thing, but if you’re going through a particularly stressful time, adding fasting might generate even more stress. Allow it to rest and instead focus on stress alleviation and self-care.
Pregnancy
While there haven’t been any particular studies, fasting is generally not a good idea if you’re pregnant or breastfeeding. You already have a lot on your plate. Concentrate on giving your child lots of high-quality nourishment while taking the best care of yourself.
Eating disorders
Intermittent fasting may not be a brilliant idea if you have a history of binge eating, anorexia, or other eating issues. Similarly, suppose you experiment with intermittent fasting and find it leads to an unhealthy connection with food. In that case, your best chance is to discontinue fasting and return to a more steady eating schedule.
The Bottom Line
Fasting benefits many people, even if it is not for everyone. It can be a valuable technique for enhancing your health, so if you’re interested, try intermittent fasting.
Fasting is simple and free, and you may plan your fasting schedule around whatever time you like. You can fast in the morning and have your last meal at night, or vice versa.
This introduction to seven various fasting styles includes a range of fast patterns, from easy fasts that occasionally skip meals to rigid multi-day fasts. Take a look around and try anything that appeals to you.
It’s worth noting that fasting works exceptionally well on the keto diet. Ketosis suppresses appetite and makes it much simpler to go for extended periods without eating by affecting two hunger hormones, ghrelin, and leptin. Keto is also beneficial for fat loss, muscular mass preservation, reducing insulin resistance, balancing insulin levels, and other benefits.
