Keto Diet For Pcos: Does It Work?

Polycystic ovary syndrome (PCOS) is a common hormonal condition affecting women of childbearing age. It is characterised by insulin resistance, high levels of male hormones (androgens), and symptoms such as irregular periods, excess body hair, and infertility. The condition can be challenging to manage, and weight loss is often recommended to improve insulin resistance and promote hormonal balance. The keto diet, a popular dietary approach, has been suggested as a potential treatment for PCOS due to its ability to improve insulin sensitivity, promote weight loss, and balance hormones. However, the effectiveness of the keto diet for PCOS management is still being explored, and more research is needed to understand its long-term effects.

Keto diet and weight loss

The keto diet is a popular eating plan for weight loss. It is a very high-fat, low-carbohydrate diet that has been touted as a way to improve insulin resistance, which is a characteristic of polycystic ovarian syndrome (PCOS). Since the keto diet may help with insulin resistance, it may also provide some benefits for people with PCOS.

On the keto diet, your carbohydrate intake is significantly decreased, which forces the body into a state of ketosis – where you burn fat instead of carbohydrates for energy. Most people on the keto diet reduce their carb intake to less than 50 grams of total carbs per day. This low-carb intake typically results in urinary excretion of ketones, which can be used to verify dietary adherence.

Research has found that the keto diet may help women with PCOS lose weight and maintain weight loss. A handful of studies have shown that the keto diet can lead to significant weight loss in people with PCOS. In one study, participants lost an average of 21 pounds (9 kg) in 45 days. Another study found that all subjects who participated through 24 weeks lost weight, with a mean body weight change of -12.1%.

In addition to weight loss, the keto diet has been found to help women with PCOS improve their balance of sex hormones, reduce triglyceride and cholesterol levels, normalize their menstrual cycles, and improve their fertility. The keto diet has also been shown to improve insulin sensitivity, which is often impaired in people with PCOS.

The keto diet is very restrictive and may be difficult to follow long-term. It requires avoiding bread, pasta, rice, cereals, potatoes, most fruits, and other foods high in sugar or carbs. Additionally, the keto diet may increase cholesterol levels, which could be a concern for people with high cholesterol.

If you are considering the keto diet to manage your PCOS, be sure to work closely with a healthcare professional so they can monitor your progress. A less restrictive low-carb diet may offer similar benefits for PCOS while being easier to adopt long-term. It is important to remember that not all keto studies can be generalized to PCOS due to potential confounding factors, and more research is needed on the long-term effects of the keto diet on PCOS.

Keto diet and insulin resistance

Insulin resistance is a defining feature of PCOS, and the keto diet is often touted as a way to improve insulin resistance.

The keto diet is a high-fat, low-carbohydrate diet that has shown promising effects in women with PCOS. Research has found it may help women lose weight and maintain weight loss, improve their fertility, optimise their cholesterol levels, and normalise their menstrual cycles.

The keto diet may improve insulin sensitivity and help balance hunger hormones. In a 12-week study of 14 women with PCOS, a keto diet high in plant foods resulted in significantly lower blood sugar and insulin levels, as well as better insulin resistance scores, indicating higher insulin sensitivity. Another study of 18 women with PCOS, liver dysfunction, and obesity found that participants who consumed a ketogenic diet for 12 weeks experienced significant improvements in blood sugar levels, suggesting an improvement in insulin sensitivity.

The keto diet may also reduce insulin resistance by improving mitochondrial efficiency and reducing oxidative stress. It can also positively impact the gut microbiome, which is linked to insulin sensitivity.

However, the keto diet is very restrictive and may be difficult to follow long-term. More research is needed to understand the long-term effects of the keto diet on PCOS.

Keto diet and testosterone levels

The ketogenic (keto) diet is a high-fat, low-carbohydrate diet that has been touted as a way to improve insulin resistance for people with type 2 diabetes. It may also provide some benefits for people with polycystic ovary syndrome (PCOS), a common hormone disorder in women that can cause infertility and increase the risk of developing diabetes, obesity, and other metabolic health problems.

PCOS is associated with elevated levels of testosterone and other androgen hormones, irregular periods, and large ovaries with many small follicles. The keto diet may help lower testosterone levels in women with PCOS, improving symptoms such as excess hair growth.

Research has found that the keto diet may help women with PCOS lose weight, improve fertility, optimize cholesterol levels, and normalize their menstrual cycles. A meta-analysis of clinical trials found that women with PCOS who followed the keto diet for at least 45 days experienced significant weight loss and improved reproductive hormone levels, including lower testosterone levels.

However, the keto diet is very restrictive and may be difficult to follow long-term. It can also lead to increased cholesterol levels, which may be a concern for some individuals. More research is needed to fully understand the long-term effects of the keto diet on PCOS and testosterone levels.

While the keto diet has been shown to increase testosterone levels in resistance-trained men, the mechanism behind this increase is not yet fully understood. Some theories suggest that the increase in cholesterol intake or secondary fat loss due to improved health may contribute to the boost in testosterone levels. However, extreme dieting and training can cause testosterone levels to drop.

In conclusion, while the keto diet may help lower testosterone levels in women with PCOS, more research is needed to understand the long-term effects and the exact mechanism behind the testosterone boost observed in some individuals.

Keto diet and fertility

The keto diet is a low-carb, high-fat diet that puts the body in a metabolic state called ketosis, where it burns stored fat for energy instead of carbohydrates. This diet has been linked to several health benefits, including weight loss, stabilised blood sugar levels, and improved fertility.

Effects on Fertility

High sugar intake can cause erratic blood sugar levels, leading to major structural and hormonal imbalances. Cells become insulin resistant and are no longer able to metabolise sugar. This, in turn, can wreak havoc on the reproductive system, affecting the function of sperm and egg cells and causing miscarriages.

The keto diet has been found to improve insulin sensitivity and promote weight loss, which can positively impact fertility. A study by Mavropoulos et al. found that a low-carbohydrate, ketogenic diet led to significant improvements in weight, percent free testosterone, LH/FSH ratio, and fasting insulin in women with obesity and PCOS over a six-month period. Additionally, two women in the study became pregnant despite previous infertility problems.

Another study by Moran et al. investigated the effects of a high-protein, low-carbohydrate diet on 45 overweight women with PCOS. The study found significant improvements in reproductive hormones and ovulation rates, with four out of 14 women experiencing improved menstrual cyclicity and one amenorrheic subject resuming menses.

Potential Drawbacks

While the keto diet may offer fertility benefits, it is important to consider potential drawbacks. The diet is highly restrictive, eliminating approximately 60% of typically consumed foods, which can make it challenging to stick to long-term. Additionally, the lack of variety may reduce the diversity of the microbiome.

The keto diet can also be taxing on the digestive tract as fat can be hard to metabolise and break down, leading to chronic fatigue. It may also lack crucial vitamins and minerals, such as potassium and vitamin C, and can be difficult to maintain long-term.

The keto diet has been linked to improved fertility, particularly in overweight and obese women with PCOS, by reducing insulin levels and improving hormonal balance. However, it is important to note that the diet is highly restrictive and may not be suitable for everyone. More research is needed to fully understand the long-term effects of the keto diet on fertility.

Keto diet and menstrual cycle

The keto diet has been found to have a positive impact on the menstrual cycles of women with PCOS. PCOS, or polycystic ovarian syndrome, is a common hormonal condition that affects women of childbearing age. It is often associated with irregular periods and infertility.

The keto diet is a high-fat, low-carbohydrate diet that has been found to improve insulin sensitivity, promote weight loss, balance hormones, and regulate menstruation in women with PCOS. Research has shown that the keto diet can lead to significant weight loss, lower testosterone levels, and improve insulin resistance in women with PCOS. These factors can help regulate menstrual cycles and improve fertility.

For example, a study at the Cleveland Clinic followed four women with PCOS on a ketogenic diet for six months. All four women lost between 19 and 36 pounds, resumed regular menstrual cycles, and two became pregnant spontaneously. Another study of 17 women with PCOS found that a keto diet reduced average blood sugar levels and insulin levels, resulting in improved insulin resistance and menstrual regularity.

The keto diet may be a promising approach for managing PCOS and improving menstrual cycle regularity in affected women. However, it is important to note that the keto diet is very restrictive and may be difficult to follow long-term. More research is needed to fully understand the long-term effects of the keto diet on PCOS and menstrual cycle regulation.
