Keto And Periods: A Hormonal Regulation Solution?

The ketogenic diet has become popular due to its health benefits, but it also has a notable effect on the menstrual cycle. The keto diet can influence the regularity of periods, with some women reporting irregular cycles or amenorrhea (absence of menstruation). This is because the female menstrual cycle is sensitive to extreme dietary changes and weight reduction. However, the effect of keto on the menstrual cycle varies for each individual woman. While some women report fewer PMS symptoms and an easier time with menstruation after starting keto, others claim that keto sent their cycles out of whack.

Keto can cause irregular periods

The ketogenic diet has become popular due to its weight loss effects and other health benefits. However, it can also influence the regularity of the menstrual cycle. A study published in 2003 reported menstrual irregularity as one of the most common side effects of the ketogenic diet in adolescent females.

When on keto, period problems were reported in 45% of female participants. This is because the female menstrual cycle is very sensitive to extreme dietary changes and weight reduction. A rapid and sudden shift in dietary patterns can affect the regularity of periods. So, when on keto, period problems might be a common occurrence.

Reasons for Irregular Periods on Keto

Rapid Weight Loss

People tend to eat less food on keto while simultaneously burning more calories, which can lead to rapid weight loss. If fat loss happens too quickly, a woman's estrogen levels will drop, potentially causing menstrual irregularities.

Calorie Restriction

Keto reduces hunger hormones, leading to significant calorie restriction, which can interfere with the female reproductive cycle. Too much calorie-cutting can also interfere with thyroid function, and disruptions in thyroid hormones are linked to disruptions in menstruation.

Stress

The dietary changes and rapid weight loss caused by keto can be stressful for the body. Prolonged periods of chronic stress and caloric restriction induced by keto might affect the normal functioning of female reproductive hormones.

Other Considerations

The effect of keto on the menstrual cycle varies for each individual woman. Women with polycystic ovarian syndrome (PCOS) have irregular periods, impaired fertility, and frequently suffer from obesity. Research indicates a positive impact of keto on the period in women with PCOS. By inducing weight loss, the ketogenic diet can restore menstruation and fertility in these women.

Additionally, a healthy body weight is necessary for normal periods. Excessive weight reduction and low body mass index can impair the regularity of the menstrual cycle. Therefore, it is essential to avoid dramatic and excessive weight loss when on keto to prevent period problems.

Keto can stop periods altogether

The keto diet can cause periods to become irregular or stop altogether. This phenomenon is called amenorrhea and is often accompanied by weight loss, a common goal for people on the keto diet. Amenorrhea seems to be one of the main side effects of the diet, with 45% of female participants in one study reporting menstrual dysfunction.

The keto diet is a high-fat, very low-carb approach that has become popular in recent years. It often leads to dramatic changes in diet and rapid weight loss, which can cause hormonal changes that influence the menstrual cycle. While keto is not the only diet that can cause this, the rapid weight loss associated with keto can be a factor.

Angela Chaudhari, M.D., a gynecologist at Northwestern Memorial Hospital, explains that rapid weight loss can alter the estrogen-progesterone balance and impact ovulation, leading to irregular periods or amenorrhea. This can also be caused by a very low-calorie diet, excessive exercise, or a very low BMI.

In addition to weight loss, the lack of carbs in the keto diet may also contribute to amenorrhea. Extreme carbohydrate restriction may lead to changes in the luteinizing hormone, which is released by the brain and contributes to regular ovulation. When carbs are restricted, this hormone may be compromised, leading to amenorrhea or hypomenorrhea (short, light periods).

While the keto diet can disrupt the menstrual cycle, it is important to note that there are individual variations. Some people may experience a return of their periods while on the keto diet, especially if they were previously overweight. Additionally, the keto diet may be beneficial for women with polycystic ovarian syndrome (PCOS) by helping to regulate their periods and improve fertility.

Keto can be beneficial for women with PCOS

Polycystic ovarian syndrome (PCOS) is a common endocrine disorder that affects women during their reproductive years. It is associated with obesity, hyperinsulinemia, insulin resistance, and infertility. Insulin resistance occurs when the body's cells stop responding appropriately to insulin, leading to elevated blood sugar and insulin levels. This can result in weight gain, ovarian androgen production, and irregular periods.

The keto diet, a low-carb, high-fat diet, has been found to improve insulin sensitivity and reduce insulin resistance, making it a potential tool for managing PCOS. By limiting carb intake to less than 50 grams per day, the body is forced into a state of ketosis, where it burns fat instead of carbs for energy.

Several studies have shown that the keto diet can improve insulin sensitivity and help balance sex hormones in women with PCOS. A 12-week study on 14 women with PCOS found that a keto diet high in plant foods resulted in significantly lower blood sugar and insulin levels, as well as improved insulin resistance scores. Another study of 18 women with PCOS, liver dysfunction, and obesity found that those on a keto diet for 12 weeks experienced significant improvements in blood sugar levels, indicating better insulin sensitivity.

In addition to improving insulin sensitivity, the keto diet has also been found to promote weight loss, reduce triglyceride and cholesterol levels, normalize menstrual cycles, and improve fertility in women with PCOS. A 45-day study of 17 women with obesity and PCOS found that the keto diet not only reduced blood sugar and insulin levels but also led to an average weight loss of 21 pounds. Over the course of the study, 5 women had their periods return after not having had one for several years, 12 women reported improved menstrual regularity, and 5 women became pregnant after previous unsuccessful attempts.

While the keto diet has shown promising results for women with PCOS, it is important to note that it is a very restrictive diet and may be difficult for some people to stick to. Additionally, larger and longer-term studies are needed to fully understand the long-term effects of keto on PCOS. It is always recommended to consult with a healthcare professional before starting any new diet, especially when managing a medical condition like PCOS.

Keto can cause weight gain during periods

The keto diet is a popular, high-fat, very low-carb approach to weight loss that has taken the diet world by storm. However, it can also have some strange effects on your period. Some women who follow the keto diet report irregular periods, while others say their monthly cycle vanishes altogether. This phenomenon, known as amenorrhea, seems to be one of the main side effects of the diet, along with weight loss.

So, can keto cause weight gain during periods? The answer is yes. Here's how:

Hormonal Changes

The keto diet can lead to rapid weight loss, especially in the initial stages. This quick weight loss can alter your body's estrogen-progesterone balance, affecting ovulation and causing irregular periods or even amenorrhea. Hormonal changes due to weight loss can also lead to a decrease in estrogen levels, which can impact bone health and fertility.

Carbohydrate Restriction

The keto diet's extreme carbohydrate restriction may lead to changes in the luteinizing hormone (LH), which contributes to regular ovulation. When carbs are restricted, LH may be compromised, leading to amenorrhea or hypomenorrhea (short, light periods).

Calorie Restriction

Calorie restriction, often associated with the keto diet, can also trigger a stress response in the body. If you're not eating enough calories, it can affect the pulsatile release of hormones from the brain, leading to irregular periods.

Fat Loss and Toxin Release

During weight loss, the release of stored hormones and toxins from adipose tissue can also impact your hormones and menstrual cycle. Although this imbalance is temporary, it can cause erratic periods.

Thyroid Function

A dramatic drop in carbohydrates can affect thyroid hormone production, especially in those with a thyroid-related disease. This can, in turn, affect the menstrual cycle.

While keto can cause weight gain during periods, it's important to note that these effects are usually temporary. Additionally, the keto diet may also help regulate periods in overweight individuals by improving ovulation. If you're experiencing period irregularities while on the keto diet, it's recommended to consult a doctor to ensure there aren't any underlying health issues.

Keto can help with painful PMS symptoms

The keto diet can be a double-edged sword when it comes to a woman's menstrual cycle. While some women report menstrual irregularities and problems, others have found that keto has helped alleviate their painful PMS symptoms.

PMS, or premenstrual syndrome, affects millions of women in the US and can cause a wide range of physical and emotional symptoms. Here are some ways in which keto can help mitigate these symptoms:

• Better sleep quality: Many people report better sleep once they're in ketosis, possibly due to the compound adenosine, which plays an important role in moderating sleep behaviour.
• Balancing insulin levels: Keto helps keep insulin levels in check, which is crucial for balancing sex hormones. It may also help prevent insulin resistance and type 2 diabetes.
• Reducing cravings: Ketosis can help lower your "hunger hormone", ghrelin, which stimulates your appetite and increases fat storage.
• Anti-inflammatory properties: Ketosis floods your blood with ketones, which are anti-inflammatory and can help mediate some of the discomfort associated with PMS.
• Improved concentration and memory: Ketones are anti-inflammatory and can be used more efficiently by the brain than glucose, which may lead to better memory, concentration, and learning.

Tips for managing PMS with keto

• Keep a hormone journal: Track your symptoms throughout the month and pay attention to where you are in your cycle to identify any subtle changes in your body.
• Test your thyroid: A super low-carb diet may cause an imbalance in your thyroid hormone, so consider increasing your carb intake slightly if you feel very lethargic.
• Exercise regularly: Exercise can increase your metabolic flexibility, help balance your blood sugar, and increase SHBG, which is responsible for binding to estrogen and testosterone.
• Take krill oil supplements: Krill oil has been found to lower stress levels, enhance mood, and decrease irritability and pain.
• Manage stress: Find ways to manage stress, such as through exercise, meditation, and deep breathing, as high levels of stress can impact your hormone balance.

Foods to support a healthy cycle

• Follicular phase: Focus on cruciferous vegetables like cabbage, broccoli, and kale, as well as high-fibre foods like berries, chia seeds, and avocados, to help balance estrogen levels.
• Ovulation: Manage blood sugar levels and have healthy snacks on hand to combat cravings. Eat foods high in vitamin B6, like pork, turkey, eggs, and spinach, to reduce bloating and breast pain.
• Luteal phase: Consume anti-inflammatory foods like omega-3 fatty acids (found in salmon, mackerel, and sardines) to reduce inflammation associated with PMS. Increase magnesium-rich food consumption (such as dark chocolate and avocados) to reduce cravings and enhance mood.
• Menstruation: Include iron-rich foods like red meat in your diet to ward off anemia if you experience heavy bleeding. Continue to increase omega-3 intake and magnesium-rich foods to reduce cramps and enhance mood.

While the keto diet may cause some initial disruptions to your menstrual cycle, it can also help alleviate painful PMS symptoms and improve overall hormone balance. By following the tips and dietary recommendations outlined above, you can optimise your nutrition and support a healthy cycle while enjoying the benefits of keto.
