How beneficial is a keto diet for PCOS?

Polycystic ovarian syndrome (PCOS) is the most common endocrine condition among women of reproductive age. Clinical characteristics include anovulation, hyperandrogenism, and polycystic ovaries. We all know that PCOS is linked to an increased risk of metabolic syndrome, cardiovascular disease, and Type 2 diabetes making it hard for PCOS women to conceive. This article talks about the effectiveness of a keto diet for PCOS.

How does keto affect hormones related to PCOS?

The ketogenic diet can have a big impact on hormones tied to polycystic ovary syndrome (PCOS). By cutting down on carbs, keto lowers insulin levels, which is especially important for women dealing with PCOS. High insulin resistance can make symptoms worse by boosting androgen production, causing irregular periods and other problems.

Keto helps keep blood sugar steady, preventing sharp insulin spikes. This steadiness can improve ovulation and help balance hormones. Plus, the low-carb and high-fat diet encourages the body to burn fat for energy, which can support weight loss. Weight loss often helps in the reduction of insulin resistance, which further benefits hormonal health.

Additionally, following the keto diet can increase levels of sex hormone-binding globulin. SHBG are generally low in PCOS women so higher to moderate levels of SHBG can lower free testosterone. As in PCOS women, the testosterone levels are high which causes them acne and unwanted hair on their face. This elevated SHBG will help PCOS women in combating acne and facial hair.

Balancing these hormones can positively affect PCOS hormones in different ways. If planned and done right, the ketogenic diet offers a valuable way to tackle hormonal imbalances linked to PCOS.

Can a keto diet help PCOS women with fertility?

Yes! To a certain extent. A keto diet can potentially help women with PCOS (polycystic ovary syndrome) in many ways:

May help in weight management

Caloric Deficit: A well-designed and well-planned keto diet can lead to consuming fewer calories. A healthy caloric deficit can promote healthy weight loss. Weight loss can greatly enhance insulin sensitivity and balance hormones in women with PCOS.

Sustained Energy: With a right high-fat focus, this diet provides a steady energy source. This stable source of energy can reduce cravings and maintain energy levels, making it easier to stick to healthier eating habits and physical activity.

May help with insulin sensitivity

Impact of Carbs: Women with PCOS often face high insulin resistance where the body struggles to respond to insulin. This can raise insulin levels, worsening PCOS symptoms and affecting fertility.

Keto Mechanism: By cutting down on carbohydrates, a low carbohydrate high-fat diet can lower insulin levels and enhance insulin sensitivity. This improvement can help regulate ovulation and hormones, potentially boosting fertility.

May help in balancing hormone

Testosterone: Many women with PCOS have high testosterone levels. This causes irregular periods and difficulties in conceiving in some women with PCOS. The keto diet might help lower these hormones by improving insulin sensitivity, decreasing inflammation and promoting healthy weight loss.

Menstrual Regularity: A balanced hormonal state and healthy weight often lead to more regular menstrual cycles which is essential for fertility. Some women may notice their cycles becoming more predictable on a keto diet.

May reduce inflammation in the body

Chronic Inflammation: PCOS is linked to chronic inflammation, which can hinder overall health and fertility. Certain foods like ultra-processed food and a diet high in carbohydrates and trans fats can accelerate this issue.

Anti-inflammatory Properties: The keto diet encourages healthy fats like avocados, coconut oil, nuts, and olive oil while minimising processed and ultra-processed carbs. The low carbohydrate shift may help decrease inflammation in the body, creating a more favourable environment for conception.

May improve ovulation in women 

Ovulatory Function: A 2023 research indicated that women with PCOS on a keto diet saw better ovulatory function. This improvement could stem from weight loss, lower insulin levels, and balanced hormones.

Fertility Treatments: For those undergoing fertility treatments, the Keto diet might help with better ovulation and can enhance the effectiveness of methods like ovulation induction or IVF.

Although women with PCOS who want to improve their fertility may benefit from a ketogenic diet in many ways, it is important to approach these dietary adjustments carefully.

Are there any risks for women with PCOS on keto?

Maybe! There might be many risks for women with PCOS on a keto diet. The risk will be higher if the keto diet is not personalised. While some women with PCOS may experience benefits like weight loss and improved insulin sensitivity, there are potential concerns/side effects to consider:

1. Micronutrient Deficiency: A strict keto diet is of course deficient in many fruits, vegetables, and whole grains. This can potentially lead to vitamin and mineral deficiencies.
2. Imbalance Hormones: Extreme changes in diet can affect hormones which is already a concern for women with PCOS. So small changes should be kept in mind while shifting your diet routine. While on the keto diet, some women may experience increased stress on the body, which can exacerbate symptoms.
3. May Impact the Menstrual Cycle: Some women may notice changes in their menstrual cycle like an increase in glycemia level when drastically altering their diet to ketogenic, which can be concerning for those managing fertility issues.
4. Fluctuation in Blood Sugar Levels: While keto can help regulate blood sugar for some, it might cause fluctuations for others, particularly if the transition to ketosis is too rapid, though rare but not uncommon.
5. Long-term Sustainability: The high-fat consumption nature of keto can make it difficult to maintain long-term, which might lead to weight regain and other metabolic issues.

Before starting any new diet, especially one as restrictive as keto, it’s important for women with PCOS to consult with a dietician. They can provide personalised advice and ensure that nutritional needs are met while managing PCOS symptoms effectively.
