Keto And Pcos: A Potential Solution?

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects the ovaries and ovulation in women of childbearing age. It is the most common cause of female infertility in the USA, affecting between 4% and 20% of women of reproductive age worldwide. PCOS is associated with irregular periods, excess hair growth, obesity, and an increased risk for type 2 diabetes. The exact cause of PCOS is unknown, but it is thought to be a combination of genetic and environmental factors.

The keto diet has been proposed as a potential treatment for PCOS. Keto is a high-fat, ultra-low-carb diet that reduces blood sugar and insulin. By cutting carbs, the diet aims to reduce glucose in the blood, which is believed to be the root cause of PCOS. Studies have shown that the keto diet can lead to weight loss and improve insulin resistance, which is a key factor in treating PCOS and increasing fertility.

While the keto diet may be a promising approach for managing PCOS, it is important to consult with a medical professional before making any significant dietary changes.

Keto can help reduce insulin levels in women with PCOS

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects women of childbearing age. It is associated with irregular or skipped periods, high levels of male hormones, and cysts in the ovaries. PCOS is the most common cause of female infertility, affecting between 4% and 20% of women of reproductive age worldwide.

Women with PCOS often have higher levels of insulin, a condition known as hyperinsulinemia, which is a primary factor in developing PCOS. High insulin levels lead to PCOS by inhibiting sex hormone-binding globulin (SHBG) synthesis, which in turn increases male sex hormones (androgens) in women. This hormonal imbalance causes problems with ovulation and can result in cysts forming in the ovaries.

Keto is a high-fat, ultra-low-carb diet that has been shown to be effective in treating PCOS. By reducing carbohydrate intake, keto helps to lower blood sugar and insulin levels, addressing the underlying causes of PCOS rather than just the symptoms. Studies have found that keto can lead to significant improvements in weight, insulin levels, and hormonal markers in women with PCOS.

One study showed that women with PCOS who followed a keto diet for six months lost an average of 12% of their body weight and reduced their insulin levels by 54%. Another study found that a low-carbohydrate diet improved weight, percent free testosterone, LH/FSH ratio, and fasting insulin in women with PCOS over a 24-week period. Additionally, a 2020 study had 14 medically overweight women with PCOS follow a keto diet for 12 weeks. At the end of the study, the women had lost a significant amount of weight, experienced a reduction in BMI, and had lower glucose and insulin blood levels.

Keto can be an effective tool for managing PCOS by reducing insulin levels and improving hormonal imbalances. However, it is important to note that building lean body mass and losing weight through other means can also help manage insulin resistance in the long term. Consulting a medical professional and a nutritionist can help determine if keto or another low-carb diet is the best approach for managing PCOS.

The diet may help with weight loss

The keto diet is a very low-carb, high-fat diet that does not restrict calories but rather the quality of foods. The idea is to burn fat by staying in a state of ketosis, where the body uses fat for energy because it does not have enough carbohydrates to burn. Studies have shown that the keto diet can lead to weight loss and improve insulin resistance, a driver of fat storage.

A small case study at the Cleveland Clinic's Obesity and Weight Management program showed promising results for weight loss in women with PCOS who followed a keto diet. Four women were followed for six months, and all four lost between 19 and 36 pounds. All four women also had a resumption of regular menstrual cycles, and two women conceived spontaneously.

Another study followed 11 women with PCOS as they followed a keto diet for six months. The five women who completed the study lost weight and improved some of their hormonal markers. Two of these women became pregnant during the study, despite previous infertility problems.

A 2020 study had 14 medically overweight women with PCOS undergo a keto diet for 12 weeks. The women had a "significant reduction in body weight", losing an average of 20 pounds and experiencing a reduction in BMI. They also had a decrease in their glucose and insulin blood levels, along with a decrease in the amount of testosterone circulating in their blood.

A 2021 study of women with PCOS, obesity, and fatty liver randomized participants to a ketogenic diet or conventional pharmacologic therapy. Those who received the ketogenic diet demonstrated better decreases in blood sugar and weight, and greater improvement in fatty liver.

While weight loss alone can lead to an improvement in PCOS symptoms, it is hard to say how much losing weight specifically with keto will make an added impact. However, considering keto when you have PCOS is "probably a good idea", according to Taraneh Shirazian, MD, an ob-gyn with NYU Langone Health.

It can lead to a reduction in male hormones

Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age. It is associated with obesity, hyperinsulinemia, and insulin resistance. Women with PCOS often have higher levels of male hormones, also known as androgens, which can lead to irregular periods, excess hair growth, obesity, and an increased risk for type 2 diabetes.

The keto diet is a popular dietary approach that involves significantly reducing carbohydrate intake and increasing fat consumption. The goal is to force the body to burn fat for energy instead of carbohydrates, thereby maximizing weight loss. The keto diet has been shown to lead to weight loss and improve insulin resistance, a key driver of fat storage.

Several studies have found that the keto diet can be effective in reducing male hormones in women with PCOS. A 2005 pilot study investigated the effects of a low-carbohydrate, ketogenic diet on overweight and obese women with PCOS over a six-month period. The study found significant reductions in body weight, percent free testosterone, LH/FSH ratio, and fasting insulin levels. Two of the women in the study became pregnant despite previous infertility problems.

Another study, published in 2013, found that reducing carbohydrate intake can lead to significant improvements in hormones and metabolic risk factors, even without weight loss. Additionally, a 2017 systematic review of clinical trials concluded that low-carb diets tend to reduce insulin levels, improve hormonal imbalances, and resume ovulation, thereby improving pregnancy rates.

The keto diet's ability to reduce male hormones in women with PCOS is likely due to its impact on lowering insulin levels and improving insulin resistance. This, in turn, can lead to a decrease in ovarian androgen production and an increase in sex hormone-binding globulin levels, resulting in lower levels of circulating free androgens in the serum.

While the keto diet has shown promise in treating PCOS, it is important to note that it may not be suitable for everyone. It is always recommended to consult with a healthcare professional before starting any new diet, especially for those with pre-existing health conditions.

Keto lowers inflammation, a root cause of PCOS

Polycystic Ovarian Syndrome (PCOS) is a hormonal disorder that affects women of childbearing age. It is associated with insulin resistance and high levels of male hormones, which can lead to infertility, irregular periods, and weight gain. The exact cause of PCOS is unknown, but it is believed that low-grade inflammation and hormonal imbalances play a role in its development.

Keto is a high-fat, ultra-low-carb diet that has been found to be effective in treating PCOS. By reducing carbohydrate intake, keto lowers blood glucose and insulin levels, which are often elevated in people with PCOS. High glucose levels are thought to be a root cause of PCOS, as they can lead to chronic hormonal disturbances and oxidative stress, also known as inflammation.

Studies have shown that the keto diet can reduce insulin resistance by up to 75%. This is important because insulin resistance is believed to be a key factor in the development of PCOS. When the body becomes resistant to insulin, it needs to produce more insulin to regulate blood sugar. This can lead to elevated insulin and blood sugar levels, causing hormonal imbalances and inflammation.

By targeting the root causes of PCOS, the keto diet can help reduce inflammation and improve hormonal balance. Additionally, keto has been found to reduce excess weight and body fat, which are often associated with PCOS. The reduction in abdominal fat may also help decrease inflammation, as visceral fat is a site of chronic inflammation.

In summary, the keto diet is a powerful tool for treating PCOS as it addresses the underlying causes of the condition, including inflammation and insulin resistance. However, larger and longer-term studies are needed to fully understand the effects of keto on PCOS.

It can help restore regular menstrual cycles

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects women of childbearing age and is a leading cause of infertility. Common symptoms of PCOS include irregular or absent menstrual cycles, excessive hair growth, and infertility. PCOS is often treated with diabetes medications that target blood sugar and insulin levels.

A keto diet can be an effective treatment for PCOS because it targets the underlying causes of the condition, not just the symptoms. By cutting carbs, you dramatically reduce glucose in your blood. High glucose levels in the blood are likely the root cause of PCOS. Glucose can lead to PCOS by creating chronic hormonal disturbances and causing chronic oxidative stress—what we commonly call inflammation.

Hormonal disturbances caused by high glucose levels raise insulin levels, leading to a condition known as hyperinsulinemia, which is a primary factor in developing PCOS. Hyperinsulinemia inhibits sex hormone-binding globulin (SHBG) synthesis, which in turn increases the levels of male sex hormones (androgens) in women. This hormonal imbalance disturbs proper ovulation by inhibiting the production of progesterone while keeping estrogen levels elevated. These hormonal imbalances cause follicles that were supposed to mature and release from the ovary to remain attached and continue to grow or leave behind a sac that can fill with fluid, causing a cyst. Over time, an ultrasound can detect the build-up of these cysts.

Other hormonal symptoms associated with PCOS include excessive hair growth, weight gain, and decreased sex drive, among others. Carbohydrate consumption has been shown to cause inflammation and oxidative stress in a host of studies, and PCOS is an inflammatory disease. Studies show that for women with PCOS, eating diets high in carbohydrates leads to oxidative stress and cellular inflammatory responses.

The keto diet is a high-fat, ultra-low-carb diet that reduces blood sugar and insulin. By restricting carbohydrates, a keto diet lowers insulin levels and reduces inflammation, making it a powerful tool for treating the root causes of PCOS.

Indeed, studies have shown that the keto diet can lead to weight loss and improved insulin resistance in women with PCOS. A small 2020 study found that 14 medically overweight women with PCOS who followed a keto diet for 12 weeks experienced a significant reduction in body weight, losing an average of 20 pounds, and a decrease in their glucose and insulin blood levels, along with a decrease in the amount of testosterone circulating in their blood.

Another analysis looking at PCOS and infertility showed that reducing insulin resistance was the key factor in treating PCOS and increasing fertility. A 2017 review of seven high-quality studies found that reducing carbohydrate load can reduce circulating insulin levels, improve hormonal imbalance, and result in the resumption of ovulation, all of which improve pregnancy rates.

While a keto diet could help women with PCOS lose weight, it may also help restore regular menstrual cycles and improve fertility. Reducing weight and insulin levels can help some women resume normal ovulation. Weight loss alone may help regulate the menstrual cycle in women with PCOS, and this is true even if only a small amount of weight is lost.

In summary, a keto diet can be a powerful tool for treating PCOS by addressing the underlying causes of the condition, including high glucose levels, insulin resistance, and inflammation. By reducing these root causes, the keto diet can help restore regular menstrual cycles and improve fertility in women with PCOS.
