Keto Diet and Its Impact on Hormonal Balance in Women

The ketogenic (keto) diet has gained immense popularity in recent years, with many people swearing by its effectiveness in weight loss and overall health improvement. However, there are concerns about how the keto diet may affect hormonal balance in women. In this article, we will explore the relationship between the keto diet and hormonal balance, addressing common questions and providing specific answers and solutions.

What is the Keto Diet?

The keto diet is a high-fat, low-carbohydrate diet that aims to shift the body’s primary source of energy from carbohydrates to fats. This metabolic state, known as ketosis, occurs when the body breaks down fats into ketones, which are then used for energy. The standard keto diet typically consists of 70-80% fat, 15-25% protein, and 5-10% carbohydrates.

How Can the Keto Diet Affect Hormonal Balance in Women?

The keto diet can have both positive and negative effects on hormonal balance in women. Some women may experience improvements in hormonal health, while others may face challenges. Here are some ways the keto diet can impact hormonal balance:

1. Insulin Sensitivity

One of the primary benefits of the keto diet is its ability to improve insulin sensitivity. Insulin is a hormone that regulates blood sugar levels, and improved insulin sensitivity can help prevent or manage conditions like polycystic ovary syndrome (PCOS) and type 2 diabetes. A study published in the journal Nutrition & Metabolism found that a low-carbohydrate, ketogenic diet led to significant improvements in insulin sensitivity in participants.

2. Estrogen and Progesterone Balance

The keto diet may also impact the balance of estrogen and progesterone, two essential hormones for women’s health. Some women may experience improvements in hormonal balance, while others may face challenges. For example, a study published in the Journal of Clinical Endocrinology and Metabolism found that a low-carbohydrate diet led to a decrease in estrogen levels in premenopausal women. This decrease in estrogen may be beneficial for women with estrogen-dominant conditions like endometriosis or fibroids. However, it may also lead to irregular menstrual cycles or amenorrhea (absence of menstruation) in some women.

3. Thyroid Function

The keto diet may also affect thyroid function, which plays a crucial role in regulating metabolism and energy levels. Some studies suggest that a very low-carbohydrate diet may lead to decreased thyroid function, potentially causing symptoms like fatigue, weight gain, and hair loss. However, more research is needed to understand the relationship between the keto diet and thyroid function fully.

4. Cortisol Levels

Cortisol, the body’s primary stress hormone, can also be affected by the keto diet. Some research suggests that a low-carbohydrate diet may increase cortisol levels, potentially leading to issues like weight gain, sleep disturbances, and mood swings. However, other studies have found no significant changes in cortisol levels following a low-carbohydrate diet. The impact of the keto diet on cortisol levels may vary depending on individual factors like stress levels, sleep quality, and overall health.

5. Adrenal Health

Adrenal health is another area that may be impacted by the keto diet. The adrenal glands produce hormones like cortisol and adrenaline, which help the body respond to stress. A sudden shift to a low-carbohydrate diet may place additional stress on the adrenal glands, potentially leading to symptoms like fatigue, dizziness, and difficulty concentrating. However, some people may experience improvements in adrenal health on the keto diet, particularly if they have insulin resistance or other metabolic issues.

How to Support Hormonal Balance on the Keto Diet

If you’re considering the keto diet or are already following it, here are some tips to help support hormonal balance:

1. Monitor your symptoms: Keep track of any changes in your menstrual cycle, energy levels, mood, and overall health. If you notice any negative changes, consider adjusting your diet or seeking guidance from a healthcare professional.

2. Ensure adequate nutrient intake: Make sure you’re getting enough essential nutrients like vitamins, minerals, and healthy fats. Include a variety of nutrient-dense foods in your diet, such as leafy greens, nuts, seeds, and fatty fish.

3. Consider a modified keto diet: If you’re experiencing hormonal imbalances on the standard keto diet, consider trying a modified version with a higher carbohydrate intake. This may help support hormonal balance while still providing some of the benefits of ketosis.

4. Manage stress: Practice stress-reduction techniques like meditation, yoga, or deep breathing exercises to help support adrenal health and overall hormonal balance.

5. Consult a healthcare professional: If you’re concerned about the impact of the keto diet on your hormonal health, consult a healthcare professional for personalized guidance and support.


The keto diet can have both positive and negative effects on hormonal balance in women. While some women may experience improvements in hormonal health, others may face challenges. It’s essential to monitor your symptoms, ensure adequate nutrient intake, manage stress, and consult a healthcare professional if needed. By taking these steps, you can help support hormonal balance while following the keto diet.
