Keto Diet: Friend Or Foe To Hormone Imbalance?

Women experience hormonal fluctuations throughout their lives, from menstruation to menopause, and these can cause a range of side effects, including depression and physical pain. Diet is one of the factors that can affect hormones, and there is evidence that a ketogenic (keto) diet may be a way to help balance them. The keto diet is a high-fat, very-low-carb approach that has been linked to weight loss and other health benefits. By reducing insulin resistance, a keto diet can help to alleviate symptoms of hormonal imbalance, such as hot flashes, night sweats, and cravings. It can also improve reproductive health by combating conditions such as polycystic ovary syndrome (PCOS). However, there are potential risks to consider, such as increased cholesterol and the impact on menstrual cycles and fertility.

Keto can help with insulin sensitivity

Keto and Insulin Sensitivity

The ketogenic diet is a low-carb, high-fat diet that causes the body to burn fat instead of carbohydrates, a process known as ketosis. While the keto diet is often associated with weight loss, it has also been linked to hormonal changes that may impact overall health and wellness.

Insulin Resistance and Uncontrolled Blood Sugar

Insulin is a hormone produced by the pancreas in response to carbohydrate consumption. When carbohydrates or sugars are consumed, the body has a glucose response, signalling the release of insulin to transport glucose into the cells. In a standard American diet, which is high in carbohydrates and sugar, this response occurs too frequently and can cause excessive blood sugar spikes, leading to insulin resistance. Insulin resistance is a common condition that often goes undetected until more serious chronic health issues develop, such as type 2 diabetes.

Keto and Insulin Regulation

The implementation of a ketogenic diet has been shown to effectively regulate insulin levels and improve blood sugar control. By reducing carbohydrate intake, the keto diet helps manage blood sugar spikes and reduces stress on the body. This, in turn, leads to lower cortisol release, allowing the adrenal glands to function properly and contributing to hormonal balance.

Keto and Reproductive Health

Polycystic Ovary Syndrome (PCOS) is a reproductive health disorder caused by an imbalance of hormones and is a common cause of infertility in women. PCOS is strongly associated with impaired glucose metabolism and insulin resistance. The ketogenic diet has been found to improve reproductive hormones and insulin levels in women with PCOS, with some even achieving pregnancy after previous fertility issues.

Keto and Thyroid Function

The thyroid gland plays a crucial role in hormone regulation, and its dysfunction can lead to various health issues. While critics argue that the keto diet may negatively affect thyroid function, others suggest that it may actually help regulate and heal the immune system, which is often the root cause of thyroid issues.

Individual Variations

It is important to note that the impact of the keto diet on insulin sensitivity may vary from person to person. Factors such as the duration of insulin resistance, physical activity level, and individual metabolic health may influence the effectiveness of the keto diet in regulating insulin. Additionally, the keto diet may not be suitable for everyone, and it is always recommended to consult with a healthcare professional before making significant dietary changes.

It may improve reproductive health

The keto diet may improve reproductive health in women with polycystic ovary syndrome (PCOS). PCOS is a metabolic and hormonal disorder that is a leading cause of infertility in women. It is associated with insulin resistance, which can lead to obesity and type 2 diabetes. By reducing carbohydrate intake, the keto diet can lower insulin spikes and improve insulin sensitivity, which in turn helps regulate hormonal imbalances.

A 2018 study found that a ketogenic diet may reduce testosterone levels in women with PCOS, which could improve fertility outcomes. The study followed four overweight women with PCOS who were trying to conceive while on a ketogenic diet. Within six months, all four women lost weight and resumed regular menstruation. Additionally, two of the women conceived spontaneously without requiring ovulation induction.

Another small study from 2003 followed 20 teenage girls using a ketogenic diet to treat epilepsy. Researchers found that 45% experienced menstrual problems, and 6 experienced amenorrhea during the 6-month study period.

Furthermore, a systematic review of seven studies found that low-carbohydrate diets improved reproductive hormones and ovulation rates in overweight and obese women. Five of the six studies that reported changes in reproductive hormones showed significant improvements. Four of the seven studies reported improvements in menstrual cyclicity, menses frequency, and/or ovulation rates, with all studies illustrating a significant improvement with a low-carbohydrate diet.

While the keto diet may improve reproductive health in some women with PCOS, it is important to note that it may not be suitable for everyone. Some critics argue that it can negatively affect thyroid function and cause nutrient deficiencies. Additionally, adhering to a restrictive diet like keto could add stress to women undergoing fertility treatments or negatively impact their relationship with food. As such, it is always recommended to consult a healthcare professional before starting any new diet, especially when trying to conceive.

It can reduce stress

The keto diet can reduce stress in a number of ways. Firstly, it can help to regulate cortisol, the body's primary stress hormone. When you eat carbohydrates, your blood sugar rises and then drops rapidly, causing a stress response in your body and leading to the release of cortisol. The keto diet has been shown to regulate blood sugar response and reduce the stress that occurs from blood sugar spikes and dips, which in turn lowers cortisol release and reduces stress on your adrenal glands.

Secondly, the keto diet can improve your body's ability to manage stress by positively impacting your brain and nervous system. Some scientific evidence supports the use of the keto diet to help treat mood disorders, including depression. The diet may positively affect your brain and nervous system by increasing levels of Gamma-aminobutyric acid (GABA), a neurotransmitter that plays a key role in managing stress, anxiety, and mood. Low GABA levels have been linked to clinical depression.

Additionally, the keto diet may improve mitochondrial function, which is often impaired in people with depression. Mitochondria are cellular components that generate the energy cells need to function. By following a keto diet, it may be easier for people with mitochondrial dysfunction to produce adenosine triphosphate (ATP), an energy-providing compound.

The keto diet may also decrease oxidative stress, which refers to cellular damage caused by free radicals. High levels of oxidative stress have been noted in people with depression. By following a keto diet, you may be able to improve markers of oxidative stress, improve your antioxidant status, and help reverse some of the damage caused by free radicals, thereby potentially improving depressive symptoms.

Furthermore, the keto diet can help regulate insulin function. Insulin resistance has been linked not only to weight gain, type 2 diabetes, and heart disease but also to depression. By limiting sugar and starch intake, the keto diet can help improve insulin sensitivity and reduce the risk of insulin resistance, thereby potentially improving mood and reducing stress.

Finally, the keto diet has some anti-inflammatory properties and may improve chronic inflammation, which has been linked to depression. Using ketones for energy generates fewer pro-inflammatory compounds called reactive oxygen species than using glucose for energy, thereby reducing inflammation in the body and potentially improving mood and stress levels.

While the keto diet has the potential to reduce stress and improve mood, it is important to note that it may have the opposite effect on some individuals. The keto diet can be difficult to adjust to, and some people may experience symptoms such as headaches, sleep disturbances, cramping, and fatigue, which can be challenging to manage and may contribute to feelings of depression. Additionally, the highly restrictive nature of the keto diet may lead to feelings of deprivation or social isolation, especially if many of your social gatherings revolve around food. Therefore, it is crucial to monitor how the keto diet affects your mental health and well-being and make adjustments as needed.

It can help with PMS

A ketogenic diet can help with PMS. The keto diet is a low-carb, high-fat diet that can help the body burn more fat, reduce hunger, and reduce blood sugar levels. This can be beneficial for women with PMS symptoms such as mood swings, irritability, and fatigue.

When following a keto diet, it is important to limit carbohydrate intake to 20-50 grams per day and focus on consuming healthy fats and moderate amounts of protein. This shift in diet can help to lower insulin levels and improve insulin sensitivity, which can lead to reduced PMS symptoms. Additionally, the keto diet can help with weight loss, which may also improve PMS symptoms.

The keto diet may also help to improve metabolic health and reduce inflammation in the body, which can have a positive impact on PMS symptoms. However, it is important to note that the keto diet may not be suitable for everyone and should be approached with caution. It is always recommended to consult with a healthcare professional before starting any new diet, especially if you have existing health conditions.

Overall, the keto diet has the potential to help with PMS symptoms by improving metabolic health, reducing inflammation, and helping with weight loss. However, it is important to approach this diet with caution and under the guidance of a healthcare professional.

It may cause irregular periods

The keto diet can cause irregular periods, and in some cases, periods may stop altogether. This is known as amenorrhea.

The keto diet is a low-carb, high-fat diet that causes the body to enter a state of ketosis, where it burns fat instead of carbohydrates for energy. This often leads to rapid weight loss, which can cause hormonal changes and affect the menstrual cycle. Estrogen levels, in particular, tend to drop as weight decreases. A study published in the Journal of Obesity and Weight Loss Therapy in September 2018 noted that keto caused disruption to women's hormonal systems.

Angela Chaudhari, M.D., a gynecologist at Northwestern Memorial Hospital, explains that rapid weight loss can alter the estrogen-progesterone balance and impact ovulation, leading to irregular periods. Additionally, extreme carbohydrate restriction may affect the luteinizing hormone, which contributes to regular ovulation. When luteinizing hormone levels are compromised, it may trigger amenorrhea or hypomenorrhea (short, light periods).

Other factors that can contribute to irregular periods on the keto diet include insufficient calorie intake, stress, and excessive exercise. The keto diet may also lead to dehydration and a lack of essential nutrients, which can further impact the menstrual cycle.

While the keto diet can initially cause irregular periods, most women's cycles will return to normal once their bodies adjust to ketosis. However, it is important to consult a doctor if irregularities persist or if there are other health concerns.
