Keto And Pcos: A Match Made In Heaven?

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects women of childbearing age. It is a leading cause of infertility and can result in symptoms such as irregular periods, excess hair growth, obesity, and an increased risk of developing type 2 diabetes. To manage PCOS, some women turn to the keto diet, which is a very low-carbohydrate, high-fat diet that aims to lower insulin levels and induce weight loss. While the keto diet has shown promise in helping to alleviate PCOS symptoms, it also has its drawbacks and may not be suitable for everyone. This article will explore the potential benefits and drawbacks of the keto diet for women with PCOS and discuss alternative dietary approaches.

Weight loss

Weight issues are common for people with PCOS, with 80% of women with the condition being obese. Many people with PCOS have tried diets and exercise programmes without much success. However, a keto diet may be a good option for losing weight.

The keto diet is a very low-carb, high-fat diet. It works by keeping carb intake so low that the body doesn't have enough glucose for its energy requirements. Instead, the body starts burning fat by-products (ketones) for energy, which is known as ketosis. This leads to lower insulin levels and improved insulin resistance.

There is some evidence that a keto diet can help women with PCOS lose weight. A 2020 study found that 14 medically overweight women with PCOS lost an average of 20 pounds and experienced a reduction in BMI after 12 weeks on a keto diet. They also had lower glucose and insulin levels, and lower testosterone levels.

A small case study at the Cleveland Clinic also showed promising results for weight loss in women with PCOS. Four women followed a ketogenic diet for six months, and all lost between 19 and 36 pounds.

A 2013 study found that reducing carbohydrates can lead to significant improvements in hormones and other metabolic risk factors, even without weight loss. However, the keto diet can be hard to follow and may not be suitable for everyone.

Other Weight Loss Options

While a keto diet may be effective for weight loss in people with PCOS, it is not the only option. Lifestyle interventions that result in weight loss can help improve PCOS symptoms. Losing even a small amount of weight may help regulate the menstrual cycle in people with PCOS.

Low-carb diets more generally can also be beneficial, as they focus on low-glycemic foods that are absorbed and metabolised more slowly, leading to more stable blood insulin levels.

For people with PCOS who are trying to get pregnant, losing weight may help to resume normal ovulation and improve fertility. A keto diet may be particularly beneficial in this case, as it can also help manage insulin resistance, which is a key factor in PCOS.

However, it's important to note that weight loss alone may not be enough to improve fertility in people with PCOS. A healthy diet and lifestyle are also key factors. Consulting a medical professional before starting any new diet is recommended.

Improved hormone profile

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects women's reproductive health. It is often associated with high levels of male hormones called androgens, insulin resistance, and irregular periods. The keto diet has been found to be a promising treatment for PCOS by improving hormone levels and reducing insulin resistance.

Weight loss and improved insulin resistance

The keto diet is a very low-carb, high-fat diet that has been shown to lead to weight loss in women with PCOS. Losing weight is one of the top strategies for reversing insulin resistance, which is a key issue for most PCOS patients as it has been found in 95% of women who don't ovulate. By reducing insulin resistance, the keto diet can help improve the body's ability to use insulin effectively and lower the risk of developing type 2 diabetes.

Improved reproductive hormone levels

The keto diet has been found to improve reproductive hormone levels in women with PCOS. In a study, women who followed a keto diet for at least 45 days experienced a reduced ratio of luteinizing hormone to follicle-stimulating hormone (LH:FSH), which is a key measure in diagnosing PCOS. Additionally, their testosterone levels decreased, and their serum sex hormone-binding globulin (SHBG) levels increased. These changes can help improve fertility and increase the chances of ovulation.

Reduced hyperandrogenism

Testosterone promotes hyperandrogenism, which is a condition associated with PCOS that leads to symptoms such as acne, unwanted hair growth, and absent menstruation. By reducing testosterone levels, the keto diet can help alleviate these symptoms.

Normalization of ovarian function

The keto diet may also help normalize ovarian function in women with PCOS. High insulin levels can increase androgen secretion from the ovaries and decrease circulating sex hormone-binding globulin (SHBG). By reducing insulin levels, the keto diet may lead to a reversal of these processes, resulting in more normal ovarian function.

Overall benefits of keto for PCOS

The keto diet has been found to improve hormone levels and reduce insulin resistance in women with PCOS, which can lead to improved fertility and a reduction in PCOS symptoms. However, it is important to note that sticking to the keto diet can be challenging, especially for people with PCOS due to their biology and hormonal milieu. It is recommended that women with PCOS speak to a healthcare professional before making any drastic dietary changes.

Improved cardiovascular health

The keto diet can be beneficial for women with PCOS, as it can help reduce insulin resistance, which is a known risk factor for type 2 diabetes, liver disease, heart attack, and stroke. By lowering insulin levels, the keto diet may also help reduce the negative effects of insulin resistance, such as menstrual irregularities and infertility.

Several studies have shown that the keto diet can lead to significant weight loss in women with PCOS. This is important because losing weight is one of the top strategies for reversing insulin resistance. Additionally, weight loss has been found to improve cholesterol and insulin levels, which can positively impact cardiovascular health.

A 2020 study found that a ketogenic Mediterranean diet followed by women with PCOS resulted in lower blood glucose and insulin levels, as well as a reduction in heart disease risk factors. This suggests that the keto diet may have a positive impact on cardiovascular health in women with PCOS.

The keto diet's ability to stabilize blood sugar levels and reduce insulin resistance may also contribute to improved cardiovascular health in women with PCOS. By lowering insulin levels, the keto diet can help the ovaries function more normally, which can lead to restored menstruation and ovulation. This can have a positive impact on cardiovascular health, as high insulin levels are a risk factor for heart disease.

While the keto diet may offer some benefits for women with PCOS, it is important to note that it may not be suitable for everyone. Some experts argue that there are better dietary approaches for managing PCOS, as the keto diet can be difficult to follow and may cause nutrient deficiencies. It is always recommended to consult with a healthcare professional before making any drastic dietary changes.

Acne reduction

Acne is a common skin condition that affects millions of people worldwide. It is often associated with hormonal imbalances, particularly an excess of androgens, which cause an increase in sebum production, leading to clogged pores and inflammation.

The Ketogenic (Keto) diet has been suggested as a possible solution to reducing acne, especially in those with Polycystic Ovary Syndrome (PCOS). PCOS is a hormonal disorder characterised by irregular periods, excess androgens, and polycystic ovaries. It affects up to 15% of women of reproductive age and is the leading cause of infertility.

The Keto diet is a high-fat, moderate-protein, and low-carb eating pattern, typically consisting of 75% fats, 25% protein, and only 5% carbs. This diet aims to shift the body into a state of ketosis, where it burns fat more efficiently.

The Keto diet addresses several factors that contribute to acne formation:

• Reducing Insulin Levels: Keto diets decrease insulin levels, which can lead to lower androgen and IGF-1 levels. This, in turn, reduces sebum production and prevents pores from getting clogged.
• Calming Inflammation: Low-carb and ketogenic diets are known for their anti-inflammatory properties. By reducing inflammation, acne becomes less red, sore, and tender.
• Decreasing IGF-1 Levels: Restricting carbs helps keep IGF-1 levels low, which regulates sebum production.

Additionally, the Keto diet promotes the consumption of skin-healthy foods like collard greens, cucumbers, cauliflower, spinach, olive oil, avocados, and fatty fish like salmon. These foods provide essential vitamins, minerals, and healthy fats that can benefit the skin.

Potential Drawbacks of Keto for Acne

While the Keto diet has shown promise in reducing acne for some individuals, it is not a one-size-fits-all solution. There are a few potential drawbacks to consider:

• High-Fat Intake: Non-healthy fats like cheese, dairy products, and butter can cause a surge of inflammation and lead to excess oil production, potentially worsening acne.
• Negative Impact on Gut Health: The high-fat and low-fibre content of the Keto diet can disrupt gut health, leading to constipation and other digestive issues.
• Keto Rash: Some individuals may experience a skin condition called "keto rash," characterised by itchy, reddish bumps on the back, chest, or stomach.

Other Tips for Acne Reduction

In addition to the Keto diet, here are some other tips to help reduce acne:

• Consume Omega-3 Fatty Acids: Fatty fish like salmon, mackerel, sardines, and herring are rich in omega-3s, which have anti-inflammatory properties and may improve skin health.
• Limit Dairy Intake: Dairy products can increase IGF-1 levels and androgen signalling, leading to increased sebum production. Reducing dairy intake may help improve acne.
• Manage Stress: Stress can contribute to acne by increasing pro-inflammatory chemicals in the skin. Finding ways to manage stress, such as yoga and meditation, may help reduce acne breakouts.
• Consistent Skincare Routine: Maintaining a consistent skincare routine, including washing the skin morning and night, can help keep pores open and reduce the risk of acne.

The Keto diet has shown potential in reducing acne, especially in individuals with PCOS, by addressing key factors such as insulin levels, inflammation, and IGF-1 levels. However, it is important to note that the diet may not work for everyone, and there are potential drawbacks to consider. Combining the Keto diet with other acne-reducing strategies, such as stress management and a balanced skincare routine, may lead to optimal results.

Improved insulin resistance

Insulin resistance is a condition that raises the risk of developing type 2 diabetes. Insulin is a hormone that helps the body control levels of blood sugar, or glucose. Insulin resistance occurs when the liver becomes insulin resistant and fails to reduce glucose production in response to insulin.

The keto diet is a low-carb, high-fat diet that has been shown to reduce weight. It changes metabolism so that energy comes from fat instead of sugar. However, research has shown that the keto diet may increase the risk of developing type 2 diabetes. A study on mice showed that the keto diet impaired the liver's ability to respond to insulin, leading to insulin resistance.

Despite the potential risks, the keto diet has been proposed as a treatment for polycystic ovary syndrome (PCOS), a common disorder that affects women of childbearing age. PCOS is caused by a hormonal imbalance that results in problems with the ovaries and irregular periods. It can also lead to infertility, excess hair growth, severe acne, and weight gain.

The keto diet has been found to improve insulin resistance in people with PCOS, which can help with weight loss and fertility. A study published in the Journal of Translational Medicine found that a group of women with PCOS who followed a keto diet for 12 weeks experienced a significant reduction in body weight, glucose, and insulin levels, as well as a decrease in testosterone levels. Another study showed that four women with PCOS who followed a keto diet for six months lost between 19 and 36 pounds and resumed regular menstrual cycles, with two of the women becoming pregnant.

While the keto diet may provide benefits for people with PCOS, it is important to consult with a medical professional before starting any new diet, especially for those with PCOS or other health conditions.
