Hirsutism is a common symptom of polycystic ovary syndrome (PCOS), a hormonal condition that affects one in ten women in their childbearing years. It is caused by insulin resistance, where the body does not respond appropriately to the hormone insulin, which regulates blood sugar levels and fat storage. As the keto diet is known to improve insulin resistance, it may also provide benefits for people with PCOS and hirsutism. Several studies have shown that the keto diet improves insulin sensitivity, balances hunger hormones, and promotes weight loss in people with obesity and type 2 diabetes. Additionally, some people with PCOS have reported a noticeable decrease in excess hair growth after cutting out dairy, which stimulates insulin production and increases testosterone levels.

What You'll Learn
Dairy and Hirsutism
Hirsutism is a condition that causes excessive hair growth in females. It is characterized by thick, coarse, dark hair growth in areas that typically have fine, thin hair, such as the face, chest, back, lower abdomen, upper arms, and lower legs. Hirsutism is commonly associated with polycystic ovary syndrome (PCOS), a hormonal condition that leads to elevated androgen levels in females. Other factors that increase the likelihood of hirsutism include family history, obesity, and certain ethnic backgrounds. While the exact cause of hirsutism is unknown, it is believed to be linked to androgen levels and hair follicle sensitivity.
Dairy consumption has been a subject of discussion in relation to hirsutism. Some individuals have shared their experiences of reducing or eliminating dairy from their diet and noticing a decrease in excess hair growth. They attribute this improvement to the reduction in hormones, specifically insulin and IGF-1, which are present in dairy products and can influence testosterone levels. However, it is important to note that the impact of dairy on hirsutism may vary among individuals, and there is limited scientific evidence directly linking dairy consumption to hirsutism.
One specific component of dairy, whey, has been highlighted as a potential contributor to hirsutism. Whey is a potent stimulator of insulin, which can lead to increased testosterone levels, potentially exacerbating hirsutism in some women. As a result, cutting out whey-containing products, such as whey protein powder, may be beneficial for managing hirsutism. Additionally, some individuals with allergies or sensitivities to dairy proteins have reported improvements in skin conditions and overall inflammation when eliminating dairy from their diet.
While there is anecdotal evidence suggesting a connection between dairy consumption and hirsutism, more comprehensive scientific research is needed to establish a direct causal link. The impact of dairy on hirsutism may vary depending on individual factors, such as allergies, hormone levels, and overall health. As such, while some individuals may find relief from hirsutism by reducing or eliminating dairy, it may not be a universal solution for everyone.
In summary, while the link between dairy and hirsutism is not yet fully understood, some individuals have found success in managing their hirsutism by reducing or eliminating dairy from their diet. This is especially notable in individuals with dairy allergies or sensitivities, as well as those with PCOS, where hormone regulation plays a significant role. However, further scientific studies are required to conclusively determine the relationship between dairy consumption and hirsutism.

Keto and Insulin Sensitivity
The ketogenic diet (KD) is a low-carbohydrate, high-fat diet that has been used for weight loss and to improve insulin resistance. However, the effects of KDs on insulin sensitivity are not yet fully understood. While some studies have shown that KDs can improve insulin sensitivity, especially in skeletal muscle, others have found that it can lead to insulin resistance.
One study found that a 3-week KD increased skeletal muscle insulin sensitivity in individuals with obesity. This was attributed to increased glucose disposal in skeletal muscle or an increased insulin-mediated suppression of endogenous glucose production. Another study on mice showed that a 2-week KD alleviated high-fat diet-induced insulin resistance in skeletal muscle by inhibiting endoplasmic reticulum stress.
On the other hand, some researchers have found that KDs can lead to insulin resistance. A study on rats found that maintenance on a KD resulted in decreased sensitivity to peripheral insulin and impaired glucose tolerance. Similarly, a study on humans found that a KD lowered myocardial fatty acid oxidation but did not affect oxygen consumption. This suggests that KDs may negatively affect glucose homeostasis.
The conflicting findings on the effects of KDs on insulin sensitivity may be due to the interaction between the diet and weight loss. It is possible that the improvement in insulin sensitivity observed in some studies is a result of weight loss induced by the KD, rather than a direct effect of the diet itself. Additionally, the duration of the diet and the individual's physical activity level may also play a role in the effectiveness of KDs in improving insulin sensitivity.
Overall, while KDs have shown some promising results in improving insulin sensitivity, especially in skeletal muscle, more research is needed to fully understand its effects. It is important to monitor biomarkers and work with a healthcare professional when considering a KD to ensure that it is safe and effective for the individual.

Weight Loss and Hirsutism
Hirsutism is a common symptom of polycystic ovary syndrome (PCOS), a common endocrine disorder in women during their reproductive years. It is characterised by insulin resistance, which is when the body does not respond appropriately to the hormone insulin, resulting in elevated blood sugar and insulin levels. Insulin resistance is thought to contribute to the development of PCOS.
A ketogenic diet is a low-carbohydrate, high-fat diet that has been shown to improve insulin sensitivity and promote weight loss in people with obesity and type 2 diabetes. By reducing carbohydrate intake, the body is forced into a state of ketosis, where it burns fat for energy instead of carbohydrates. Several studies have found that a keto diet may be effective in managing PCOS symptoms, including hirsutism, by improving insulin sensitivity and reducing testosterone levels.
In one 12-week study, 14 women with PCOS followed a ketogenic Mediterranean diet and experienced significantly lower blood sugar and insulin levels, as well as improved insulin resistance scores. Another 12-week study on a plant-food-rich keto diet resulted in an average weight loss of 21 pounds (9 kg) and significant improvements in cholesterol levels and testosterone reduction. A third 45-day study found that a keto diet reduced average blood sugar levels and insulin levels, in addition to an average weight loss of 21 pounds (9 kg).
While the keto diet has shown promising results in improving PCOS symptoms and promoting weight loss, it is important to note that there is no consensus on the ideal dietary pattern for PCOS management. A very low-calorie ketogenic diet (VLCKD) should be carefully prescribed and guided by professionals. Additionally, other dietary interventions, such as a low GI diet rich in legumes, have also been found to improve PCOS symptoms, including hirsutism.

Mediterranean Diet and PCOS
Polycystic ovary syndrome (PCOS) is the most common female endocrine disorder, characterised by chronic anovulation, hyperandrogenism, and polycystic ovaries. Obesity, low-grade chronic inflammatory status, and insulin resistance often coexist in PCOS. Insulin resistance affects 50% to 75% of people with PCOS. Insulin resistance can cause the body to produce more insulin, which in turn leads to the production of testosterone, which makes PCOS worse.
The Mediterranean diet is commonly recommended by dietitians for people with PCOS. It is an anti-inflammatory dietary pattern, which is rich in complex carbohydrates, fibre, and high in monounsaturated fat. The Mediterranean diet eliminates saturated fats, processed meats, and refined sugar, which makes it a powerful tool to address inflammation. The diet includes whole grains, fruits, and vegetables, which are high in vitamins and phytochemicals. The intake of healthy fats common in the Mediterranean diet, such as olive oil, nuts, and seeds, can improve insulin sensitivity. The Mediterranean diet is also high in omega-3-rich fish, such as salmon, and non-starchy vegetables such as leafy greens, tomatoes, mushrooms, peppers, and broccoli.
The Mediterranean diet has been shown to improve fertility in people with PCOS. The diet improves body composition, which can regulate ovulation and increase the chances of pregnancy. The ability of the Mediterranean diet to lower fasting insulin and inflammation also plays a role in improving fertility. Studies have found that following a Mediterranean diet decreased ovarian volume and may improve ovarian function. The Mediterranean diet is non-restrictive and sustainable long-term.
In addition to the Mediterranean diet, other dietary interventions have been explored for PCOS. There is some evidence that a ketogenic diet may be beneficial for people with PCOS. A ketogenic diet can reduce the levels of circulating insulin and consequently also those of IGF-1, thus suppressing the stimulus on the production of androgens, both ovarian and adrenal. A very low-calorie ketogenic diet (VLCKD) has been shown to be beneficial not only in obesity but also in the treatment of other metabolic diseases. However, it is important to note that a VLCKD should be prescribed and carefully guided by professionals. Additionally, some people with PCOS have found that cutting out dairy, specifically whey, can help improve hirsutism within three to six months.

Low GI Diets and PCOS
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women during their reproductive years, with an estimated prevalence of 6 to 15%. It is associated with a high risk of cardiovascular disease, infertility, and type 2 diabetes. Women with PCOS are intrinsically insulin resistant, and the onset of PCOS has been linked to insulin resistance.
A ketogenic diet (KD) is a low-carbohydrate, high-fat diet that has been studied for its effects on overweight women with PCOS. A very low-calorie ketogenic diet (VLCKD) has shown promising benefits in obesity and other metabolic diseases. A study on a group of 60 women with PCOS found that probiotic and selenium co-supplementation significantly improved testosterone levels, hirsutism, and high-sensitivity CRP levels.
Low-GI diets have been found to improve insulin sensitivity, regulate menstrual cycles, and reduce the risk of comorbidities associated with PCOS, such as obesity, type 2 diabetes, and cardiovascular disease. A low-GI diet has also been shown to improve menstrual regularity and decrease acne occurrence in overweight and obese women with PCOS. In addition, a study comparing a low-GI diet to a conventional healthy diet in overweight and obese women with PCOS found that the low-GI diet resulted in greater improvement in insulin sensitivity and menstrual cyclicity.
While there is no consensus on the ideal dietary pattern for PCOS, nutritional approaches are essential in controlling body weight, insulin resistance, and treating associated comorbidities. Weight loss has been shown to improve metabolic derangements and body composition in women with PCOS. Additionally, a Mediterranean diet has been associated with improved infertility and other metabolic benefits in women with PCOS.
Overall, a low-GI diet, in combination with other lifestyle changes such as regular exercise and adequate sleep, can be beneficial in managing the symptoms of PCOS.
