It is not your fault, that you are having trouble losing weight. Did you know the main culprit is your hormonal imbalance?

Intermittent fasting and hormone imbalance for women over 40 are common however some studies have shown positive results with doing intermittent fasting.

Being a professional healthcare myself, I would recommend doing intermittent fasting over 40 after I have assessed my patients’ health condition. However, if you have problems with:

  • You regularly experience low blood sugar level
  • You are underweight
  • You are immunocompromised
  • You have an eating disorder

I wouldn’t suggest you do intermittent fasting. I would implore you to find the nearest healthcare provider and seek help and get medical advice.

What is Intermittent Fasting?

Intermittent fasting in layman’s terms is time-restricted feeding. The are no rules about how many calories you can take, just when you eat them.

However, I insist that while you are fasting for women over 40, the best practice is you should choose a well-balanced and nutritious meal to break fast.

Subsequently, you wouldn’t need to worry to count calories as eating right will help you feel fuller, and eventually, you will lose weight.

Before I explained more in-depth about intermittent fasting for women over 40, to make this plan succeed, it is important that you are able to manage your stress and have good quality sleep.

Intermittent Fasting And Hormonal Imbalance

Hormonal imbalance can lead to health problems and uncomfortable symptoms. Because hormones are involved in so many body processes, even a slight imbalance can have unpleasant effects.

Women are more sensitive to fasting compared to men due to hormones.

Hormones play important role in the metabolic process, reproduction growth, sexual function, water and electrolyte balance, cognitive function and mood, hunger, thirst, and body temperature.

All hormones are important, but I will highlight specific hormones in women that play the biggest role in a woman’s health:

Estrogen: One of a woman’s two main sex hormones. It helps control your menstrual cycle, plays a vital role in reproduction, protects bone health, keeps cholesterol levels under control, and affects your heart, skin, and brain (that’s including your mood).

Progesterone: The other main sex hormone. It helps to regulate your menstrual cycle, prepares your body for conception, and controls your sexual desire.

Testosterone: Testosterone is the main male sex hormone, but women have it too in small quantities. In women, testosterone contributes to bone strength, maintains ovarian function, and plays a role in sexual health and desire.

In order for your ovaries to function well, need to have a balance between estrogen and testosterone.

Gonadotropin-releasing hormone (GnRH): GnRH is classified as a releasing hormone. It acts on the pituitary gland, signaling it to make and release luteinizing hormone (LH) and follicle-stimulating hormone (FSH)

Luteinizing Hormone (LH): LH is released by the pituitary gland. It helps regulate your menstrual cycle and triggers ovulation or the release of an egg from the ovary. LH levels are highest before you ovulate.

Follicle-stimulating hormone (FSH): FSH regulates your menstrual cycle and triggers the growth of eggs in your ovaries. FSH levels are highest right before ovulation.

Does Intermittent Fasting Help Balance Hormones?

My concern when it comes to us, women, is that doing intermittent fasting incorrectly can disrupt one of all of these crucial hormones, leading to infertility or trouble conceiving.

When hormones are in perfect balance, everything in your body will sync harmoniously and make you feel good.

However, if hormones become unbalanced, health problems and uncomfortable symptoms will appear.

Because hormones are involved in so many body processes, even a slight imbalance can have wide-ranging effects.

Some of the signs of hormonal imbalance in women:

  • Bloating
  • Irritability
  • Heavy or irregular periods
  • Vaginal dryness
  • Inflammation in the vaginal walls
  • Pain during sex
  • Night sweats
  • Thinning hair and/or hair loss
  • Increased hair growth on the face
  • Darkening of the skin
  • Skin tags
  • Weight gain and/or trouble losing weight
  • Acne
  • Blurred vision
  • Increased sensitivity to cold and heat
  • Dry skin
  • Puffy face
  • Bowel problems like constipation and/or diarrhea
  • Changes in heart rate
  • Sudden weight loss
  • Frequent urination
  • Muscle weakness
  • Muscle aches and pains
  • Pain, stiffness, and swelling in the joints
  • Depression
  • Anxiety
  • Increased sweating
  • Prominent stretch marks, usually purple or pink in color
  • Increased hunger
  • A fatty hump between the shoulders sometimes called a buffalo hump

Above said signs of hormonal imbalance are due to common diet and lifestyle habits that women tend to overlook such as:

  • Eating late at night
  • Eating lots of sugar
  • Having too much stress
  • Not getting enough sleep
  • Drinking too much coffee
  • Having nutrient deficiencies
  • Having an unhealthy diet
  • Lack of regular exercise.
  • Using toxic beauty and cleaning products
  • Use certain plastics

And if you are not careful about your approach, there’s that potential that intermittent fasting can earn a spot on that list too.

Hence, you might have heard people say that intermittent fasting for women over 40 shouldn’t be done but that’s not necessarily true.

If you ease into it, listen to your body cue, and do it right, intermittent fasting at age 40 can actually help to keep your hormones balanced.

You just need to get your stress levels and hormones under control.

How Do You Do Intermittent Fasting For Women Over 40?

One of the most important steps before you even start to do intermittent fasting over 40, is deciding when you and your body are ready to start fasting.

This is the most crucial step.

Now, don’t be misunderstood that you need to be in perfect health to start fasting. After all, you might want to try intermittent fasting to correct some weight issues or health problems that you are currently facing.

But if you have good stress level management, and are not overwhelmed by life in general you can increase your success rate ten-fold.

Some signs that you are ready to start fasting for women over 40 are:

  • You don’t feel completely overwhelmed by stress
  • You have enough energy to get through the day
  • You feel rested (or at least somewhat rested)
  • Exercise makes you feel tired but energized, instead of completely drained.
  • You’re able to feel relaxed, rather than completely wound up all the time.

Once you are ready and decide to start fasting. Do it in small, actionable steps, and build on these steps over time.

This will help you from getting overwhelmed and make it easier for you to stick to intermittent fasting for the long term.

The best way is to know your eating habits.

Whether you are practicing small frequent meals or three large meals with snacking in between, you can start by not following a specific fasting protocol but making small changes that will help your transition easier.

If you’re someone who eats a lot of snacks, make it your goal to stick to meals only.

Once you nailed it, try to skip breakfast. When that becomes easy, start eating your dinner early, half an hour or an hour at a time.

Making small goals, and hitting them will help your body to adjust and prepare.

I highly recommend that you start an intermittent fasting journal thus can help you to record and keep track of your progress, food intake, and habits.

Research showed those who keep journals are more successful in losing weight and keeping it off for good.

Best Intermittent Fasting For Women Over 40

Crescendo Fasting – Crescendo method fasting is a type of fasting where you gradually increase in intensity. Rather than jump into doing 16:8 intermittent fasting try to do twelve to fourteen hours a few days per week.

It’s best to make these fasting days non-consecutive, like Monday, Wednesday, and Friday for example.

This method helps to ease your body slowly and avoid shocking the body too much at once and to ensure your hormones don’t react negatively.

Time-restricted Fasting – This is the most popular and well-known form of intermittent fasting. With time-restricted fasting, you choose a specific eating window and a specific fasting window and stick to it every day.

You can choose to do 12-hour, 14 hours, or 16-hour fasts. If you choose 12 hour fast, you would eat between 8 am – 8 pm. For 14 hours you will eat between 10 am – 8 pm.

A 16:8 intermittent fasting has an eating period window between 12 pm to 8 pm.

My advice would be to start slow and learn to listen to your body signal. If you feel you are ok then gradually increased the intensity like in crescendo fasting.

If you are worried, your body might not get the best results if you do less than 16:8 intermittent fasting then I can reassure you that based on a published study even those who manage to fast 10 hours are able to reduce weight, waist circumference, lower cholesterol, and blood sugar level.

Alternate-day Fasting – As its name suggests, you fast every other day and eat whatever you want on the other days.

The most common way to do alternate-day fasting is by limiting your calorie intake to 25 percent of your needs on fasting days and then eating 125 percent of your calorie needs on feast days.

For example, if you need 2,000 calories per day to sustain your energy, then you would eat 500 calories on Tuesday, Thursday, and Saturday and 2,500 calories on Monday, Wednesday, Friday, and Sunday.

5:2 Intermittent Fasting – This method is almost similar to alternate-day fasting, the difference is you fast on two nonconsecutive days of the week and eat normally on the other five days.

This method has you eating about 500-600 calories on each of your fasting days.
