Keto diet may improve fertility issues caused by PCOS, study finds — Nutritionist for keto diet in Costa del Sol

27/10/2023

Approximately 8-13% of reproductive-age women worldwide struggle with polycystic ovary syndrome (PCOS). Although PCOS currently has no known cure, there are treatments that can help manage symptoms and lessen the disease's impact on your health. A recent study published in the Journal of the Endocrine Society provides new insight into the potential benefits of the ketogenic diet for women with polycystic ovary syndrome (PCOS). Here we talk about this study and how our nutritionist for keto diet in Costa del Sol can help.

The PCOS Dilemma: Hormonal Disruption and Fertility Problems

When the ovaries produce an excessive amount of testosterone and other androgens, PCOS develops. Ovulation can be hampered by a hormonal imbalance, which can cause irregular periods and infertility. The inability to conceive is a problem for 70-80% of women of reproductive age who have PCOS.

In addition, there is a wide range of symptoms associated with PCOS:

Oily, acne-prone skin
Excess body hair
Weight gain and difficulty losing weight
Thinning hair and male-pattern baldness
Skin tags
Low libido
Fatigue
Pelvic pain

Will Going Keto Help Your PCOS?

A team from the Ministry of Health Malaysia decided to explore the impact of the ketogenic diet on PCOS, focusing on its effects on reproductive hormone levels. Seven clinical trials were carefully examined, all of which included women with PCOS who had followed the ketogenic diet for at least 45 days.

The results were promising:

Significant weight loss
Improved reproductive hormone levels
Reduced testosterone levels

PCOS is a hormonally complex condition characterised by hyperandrogenism and decreased insulin sensitivity. Inducing physiological ketosis through the keto diet can reduce circulating insulin and IGF-1, suppressing adrenal and ovarian androgen production, thereby limiting free androgen levels.

The Mechanism Behind Keto's Impact on PCOS

To understand how the keto diet works its magic, we need to delve into how our bodies handle carbohydrates. Blood sugar levels rise after eating carbohydrates because of their breakdown into glucose. In response, insulin is secreted by the pancreas to facilitate glucose transport to the body's cells.

However, insulin does not work properly in people with insulin resistance (a common occurrence in PCOS), leading to high blood sugar and tired cells. Low-carb diets, like the keto diet, can improve insulin resistance, testosterone levels, and even BMI.

The keto diet's core principle is to emphasize protein and healthy fats while minimizing carb intake. By depleting the body's sugar stores, it triggers the breakdown of body fat for energy.

A Growing Body of Evidence

The association between the ketogenic diet and polycystic ovary syndrome (PCOS) has been the subject of previous studies. A study published in 2020 found that the ketogenic diet is effective for PCOS patients without the use of pharmaceuticals. Another study, published in November 2021, confirmed that PCOS-affected women who followed a low-carb diet saw an increase in fertility. Very low-calorie ketogenic diets were even linked to improved metabolic and ovulatory dysfunction in PCOS patients in a study published in October 2022.

Unveiling the PCOS-Insulin Resistance Connection

Risk factors for polycystic ovary syndrome include insulin resistance, obesity, and genetics, but the exact cause of PCOS is unknown. Studies have indicated that 35–80% of women with PCOS also experience insulin resistance, where the body doesn't utilize insulin effectively. This condition can lead to inflammation, elevated testosterone levels, weight gain, and ultimately, fertility issues. Furthermore, insulin resistance increases the likelihood of developing diabetes, which can further disrupt fertility.

The keto diet's potential benefits for PCOS are promising, especially for those dealing with insulin resistance. Our nutritionist for keto diet in Costa del Sol recommends low-carb diets to patients with PCOS to control insulin levels and reduce testosterone levels. However, it's essential to consider individual factors when deciding on a dietary plan:

Age
Baseline BMI
Gender
Baseline health status
Presence of kidney and liver impairments
Gut health

Keep in mind that the keto diet may not be suitable for everyone, particularly pregnant individuals, those with specific health conditions like hypothyroidism, or individuals with eating disorders. Before making any dietary changes, consult with a gynecologist, endocrinologist, and dietitian to determine the best approach for your unique situation.
