Period And Keto: Should You Start During Menstruation?

The keto diet has been linked to weight loss and other health benefits, but it can also have a strange effect on your period. Some women who follow the keto diet report irregular periods, while others say their monthly cycle vanished altogether. This phenomenon is called amenorrhea and seems to be one of the main side effects of the diet. In this article, we will explore the effects of the keto diet on the menstrual cycle and provide tips for maintaining a healthy cycle while following a low-carb diet. We will also discuss the potential benefits of the keto diet for women with ovarian cysts or polycystic ovarian syndrome (PCOS).

Keto can cause missed or irregular periods

The keto diet can lead to weight loss and a host of other possible health benefits. However, it may also be the reason your cycle is irregular or has halted completely. Dramatic changes to your diet can lead to hormonal changes that may influence your menstrual cycle.

The keto diet can result in quick weight loss because it causes your body to burn fat instead of carbs through a process called ketosis. John Thoppil, MD, a board-certified obstetrician-gynecologist, says low-carb intake has been linked with disrupted periods. He agrees that changes in your period are likely related to weight loss and not keto specifically.

Quick weight loss can cause hormonal changes that affect the menstrual cycle. Estrogen is responsible for regulating the menstrual cycle, and as weight drops, so do estrogen levels. A study found that when participants lost an average of 17 pounds, their levels of the estrogen hormones estrone and estradiol decreased by 5.7% and nearly 10%, respectively.

Another factor that can affect the menstrual cycle is the release of stored hormones during weight loss. Adipose tissue stores hormones, pollutants, toxins, and other substances that are slowly released into the bloodstream during weight loss. As these extra components enter the blood, they can affect the menstrual cycle.

Additionally, a drop in carbohydrates can affect thyroid hormone production, which is linked to reproductive health. A gradual reduction in carbohydrates may be a better approach for those susceptible to impaired thyroid function.

If you are experiencing irregular or missed periods while on the keto diet, it is recommended to consult a doctor to rule out any concerning problems or pregnancy.

Weight loss affects estrogen levels

Weight loss can affect estrogen levels in the body. Estrogen is one of the two primary female sex hormones, and it plays a role in the onset of puberty and the menstrual cycle. Estrogen levels can be affected by a variety of factors, including menopause, ovary removal, lactation, and Turner syndrome.

During menopause, estrogen levels decrease, which can lead to weight gain, particularly around the midsection and abdomen. This is because estrogen helps regulate metabolism and body weight, and lower levels can lead to changes in a person's ability to recognize hunger, resulting in overeating. Additionally, age-related factors such as reduced physical activity and less muscle mass can also contribute to weight gain during menopause.

Estrogen levels also remain low after giving birth and while breastfeeding, as this encourages milk production and prevents further conception. In the case of ovary removal or Turner syndrome, estrogen levels can drop suddenly, leading to potential weight gain.

Treating the underlying cause of low estrogen may help manage weight gain. This could involve estrogen therapy, which has been shown to increase estrogen levels and potentially aid in weight loss. However, it's important to note that estrogen is not specifically a remedy for weight management.

Maintaining a healthy weight can be achieved through a combination of consuming a diet rich in fresh foods, staying hydrated, and getting regular physical activity. Strength training and cardio exercises can also help build muscle and promote healthy bones.

Calorie restriction can interfere with the menstrual cycle

The female body requires a certain number of calories to function properly. When there is a significant calorie deficit, the body may stop producing the hormones required for ovulation, which can cause a person's period to stop. This is known as amenorrhea. Amenorrhea can also be caused by extreme psychological stress, excessive exercise, and low-calorie diets.

Additionally, rapid weight loss can cause a drop in estrogen levels, which can also lead to menstrual irregularities. Estrogen is responsible for regulating the menstrual cycle, and when weight and estrogen levels drop, so do estrogen levels. This can further lead to a decrease in bone density and an increased risk of osteoporosis.

Furthermore, calorie restriction can interfere with thyroid function, which is also linked to disruptions in menstruation. Disruptions in the thyroid hormones T3 and T4 are often seen on low-carb diets. However, it is unclear whether this decline is a cause for concern, as low-carb diets may be therapeutic for certain thyroid disorders.

Overall, while a low-calorie diet may be beneficial for weight loss, it is important to ensure that it is not interfering with the normal functioning of the female reproductive system. A balanced and nutritious diet is crucial for maintaining a healthy menstrual cycle.

Keto may help improve reproductive health in women with PCOS

The ketogenic diet is a high-fat, very low-carb approach that has been linked to weight loss and other health benefits. However, it can also affect the menstrual cycle. Some women who follow the keto diet report irregular periods or even a complete halt in their cycle, known as amenorrhea. These changes are likely due to rapid weight loss, which can cause a decrease in estrogen levels and influence menstrual regularity.

While the keto diet can have varying effects on the menstrual cycle, it may offer specific benefits for women with polycystic ovary syndrome (PCOS). PCOS is a common hormonal disorder affecting 7-10% of women of childbearing age, and it can lead to infertility and an increased risk of metabolic health issues such as diabetes and obesity.

Here's how the keto diet may help improve reproductive health in women with PCOS:

• Lower testosterone levels: The keto diet has been found to lower testosterone levels in women with PCOS. This can help with symptoms such as excess hair growth and acne. Additionally, lower testosterone levels may improve fertility outcomes.
• Improved fertility: The keto diet may improve fertility in women with PCOS. A 2017 meta-analysis suggested that low-carb diets could enhance fertility outcomes in overweight and obese women.
• Weight loss and weight management: The keto diet is known for its effectiveness in weight loss and weight management. Losing weight can be beneficial for women with PCOS, as obesity is a risk factor for developing metabolic health issues associated with PCOS.
• Improved insulin sensitivity: PCOS is linked to insulin resistance, which can lead to higher testosterone levels and interfere with regular ovulation. The keto diet can improve insulin sensitivity, reducing insulin spikes and helping regulate hormonal imbalances.
• Normalized menstrual cycles: By improving insulin sensitivity and lowering testosterone levels, the keto diet may help normalize menstrual cycles in women with PCOS.

While the keto diet may offer these potential benefits for women with PCOS, it is important to note that it may not work for everyone. It is always advisable to consult with a healthcare professional before starting any new diet, especially if you have an existing health condition.

Carbohydrates are important during the first phase of the menstrual cycle

Carbohydrates are an essential source of energy for the body. They are one of three macronutrients, along with protein and fat, that provide the body with fuel to function properly. Carbohydrates are particularly important during the first phase of the menstrual cycle, known as the follicular phase.

During the follicular phase, the body is more sensitive to insulin, which means that it can more effectively take up glucose into the cells and metabolize carbohydrates for energy. This is due to the higher levels of estrogen during this phase, which increases insulin sensitivity. As a result, the body is better able to utilize carbohydrates for fuel, making this the ideal time to consume carbohydrates.

Consuming carbohydrates during the follicular phase can help ensure that the body has the energy it needs to function optimally. This is especially important for athletes or individuals who engage in regular physical activity. Additionally, the follicular phase is a critical time for strength training and muscle growth, as studies have shown that strength training has a greater effect during this phase.

To support the increased need for carbohydrates during the follicular phase, it is recommended to include complex carbohydrates in the diet, such as quinoa and sweet potatoes. These foods can provide a sustained release of energy throughout the day and help individuals feel more energized and less lethargic.

In summary, carbohydrates play a crucial role in energy production, and their importance is heightened during the first phase of the menstrual cycle due to increased insulin sensitivity and metabolic changes. By understanding these hormonal fluctuations and adjusting dietary choices accordingly, individuals can optimize their energy levels and support their overall health and well-being.
