Cortisol And Keto: Can Stress Hormones Block Weight Loss?

The ketogenic diet is a very low-carbohydrate diet that requires less than 50 grams of carbohydrates per day to reach ketosis, a metabolic state in which fat is used for energy instead of carbohydrates. While the keto diet has been shown to improve health under a wide variety of conditions, it may also increase levels of cortisol, the body's main stress hormone. This is because limiting carbohydrate intake causes a starvation response in the body, which triggers the release of cortisol to increase energy levels. Chronically elevated cortisol can have negative impacts on the body, including an increased risk of disease, impaired sleep, lower immune function, and increased abdominal fat and weight gain. However, the relationship between ketosis and high cortisol is not yet fully understood, and any elevation in cortisol from keto is probably temporary. Furthermore, a well-formulated keto diet containing adequate sodium is unlikely to alter cortisol levels significantly.

Cortisol is released as a result of stress, which can be caused by a keto diet

Cortisol is your body's main stress hormone. It is released by your adrenal glands when you experience a stressful or frightening situation, preparing your body to take immediate action. This can happen when you feel threatened, whether the threat is real or hypothetical.

Limiting your carb intake to the degree that the keto diet requires causes a starvation response in the body. In an effort to increase energy levels, the body triggers the release of stress hormones like cortisol. Cortisol then increases insulin resistance and stimulates gluconeogenesis to help increase blood sugar levels. Therefore, the keto diet can be stressful for the body at first.

However, when you are consistently in ketosis, your cortisol levels will decrease because you will be using alternative fuel sources like ketones and fat and will have a greater capacity to spare glycogen (your body's sugar stores). Thus, you will no longer need as much cortisol to promote an increase in blood sugar levels.

Chronically elevated cortisol resulting from high stress loads can be damaging to your body, contributing to hormonal imbalances and negatively impacting your metabolism. It can drive insulin resistance, impair your body's ability to effectively burn carbs for energy, and make you more likely to store fat. Chronic insulin resistance is also tied to chronic diseases like diabetes, PCOS, and cardiovascular disease.

Cortisol also competes with progesterone, which is the dominant hormone in the second phase of the menstrual cycle. When cortisol steals this progesterone, it can lead to female health issues, affecting your period, fertility, and body's ability to counter estrogen.

High cortisol levels can lead to insulin resistance, which impairs the body's ability to burn carbs for energy

Cortisol, also known as the "stress hormone", is produced by the adrenal glands and is essential for survival. It is one of the key hormones that the body releases in response to stress, along with adrenaline. When an individual experiences a stressful or frightening situation, the adrenal glands start pumping out cortisol, which increases heart rate and blood pressure and shuts off digestive and reproductive functions, providing the body with more energy to deal with the stressor.

Cortisol also works with insulin to regulate the breakdown of carbohydrates, proteins, and fats according to the body's energy intake and needs. Insulin is a hormone produced by the pancreas that helps move glucose from the blood into cells for energy. When the body experiences stress, cortisol prompts the liver to release glycogen into the bloodstream, which gets converted into glucose. This leads to an increase in blood glucose levels, which signals the pancreas to produce more insulin to bring those levels back to normal.

High levels of cortisol over an extended period can negatively affect insulin sensitivity and glucose regulation. It can promote beta cell death in non-diabetics, reduce insulin sensitivity, and disrupt glucose regulation. It can also lead to hyperglycemia, which is associated with various health issues such as cardiovascular disease, obesity, and diabetes.

Additionally, chronically elevated cortisol levels can lead to insulin resistance. Insulin resistance occurs when the body's cells do not respond appropriately to insulin, impairing the body's ability to regulate blood glucose levels effectively. This can result in elevated blood glucose levels, which, if left unchecked, can progress to prediabetes and Type 2 diabetes.

Therefore, it is crucial to manage stress and maintain healthy cortisol levels to support overall health and prevent complications associated with insulin resistance and hyperglycemia.

Insulin resistance can also lead to fat storage

Insulin resistance can lead to fat storage in the body in several ways. Firstly, when a person has type 2 diabetes, their pancreas produces enough insulin, but their cells do not use it efficiently. This results in a condition called insulin resistance, where the pancreas compensates by producing even more insulin. Insulin is a hormone that regulates blood sugar levels and promotes fat storage. While insulin helps cells absorb glucose for energy, excess glucose can be converted into fat for long-term storage.

Secondly, eating more carbohydrates than the body can process leads to high blood glucose levels. Carbohydrates are broken down into simple sugars during digestion. If the cells do not effectively remove glucose from the blood, the body stores it as fat, leading to weight gain. This is particularly relevant for people with diabetes, as they may also gain weight due to their body's improved ability to absorb glucose as a result of insulin therapy.

Additionally, high cortisol levels, which can be triggered by stress, can contribute to insulin resistance. When the body experiences stress, it releases cortisol, a stress hormone, to increase energy levels. This, in turn, can lead to increased insulin resistance and stimulate gluconeogenesis, a process that raises blood sugar levels. While the keto diet can initially lead to increased cortisol levels due to the body's starvation response to low carb intake, consistently maintaining ketosis over time will decrease cortisol levels as the body adapts to using alternative fuel sources like ketones and fat.

Cortisol can compete with progesterone, which can lead to female health issues

Cortisol is a hormone produced and released by the adrenal glands. It is the body's main stress hormone and is responsible for the "fight-or-flight" response. When the body experiences a stressful or frightening situation, the adrenal glands start pumping out cortisol, which increases heart rate and blood pressure, and shuts off digestive and reproductive function. Cortisol also plays a role in regulating the sleep-wake cycle and controlling blood pressure and heart rate.

Progesterone is a hormone that is produced by the ovaries and adrenal glands. It is often referred to as the "pregnancy hormone" as it plays a crucial role in supporting pregnancy. Progesterone also has a role in regulating the menstrual cycle and maintaining the uterine lining.

Cortisol and progesterone have been found to interact with each other in the body. Cortisol can compete with progesterone for receptors, which can affect the levels of both hormones. This competition can lead to an imbalance in female health, including irregular periods, decreased libido, and infertility.

Studies have shown that stress can increase cortisol levels and decrease progesterone levels. This imbalance can have negative consequences for female reproductive health. Additionally, high cortisol levels can lead to an increase in abdominal fat, which can further impact reproductive health.

The keto diet has been found to affect cortisol levels. In the short term, the keto diet can cause a stress response in the body, leading to increased cortisol levels. However, once the body adjusts to the diet and enters a state of ketosis, cortisol levels tend to decrease.

While the keto diet may impact cortisol levels, there is limited research on its direct impact on progesterone levels. However, given the interplay between cortisol and progesterone, it is possible that the keto diet could indirectly affect progesterone levels.

Overall, while cortisol can compete with progesterone and impact female health, the specific effects of the keto diet on this interaction are not yet fully understood and require further research.

Cortisol can be managed by changing your perception of stress

Cortisol is the body's main stress hormone, produced and released by the adrenal glands. It is one of the body's “fight-or-flight” hormones, which prepare your body to take immediate action in stressful or frightening situations. While short-term cortisol release can help you run away from danger, when cortisol levels are too high for too long, it can lead to health issues like weight gain, high blood pressure, heart disease, and chronic diseases.

Chronic stress can lead to cortisol dysregulation, resulting in either consistently high or low cortisol levels, both of which can have negative impacts on your health. High cortisol levels have been linked to issues such as high blood pressure, compromised immune function, insomnia, and mental health problems.

• Mindfulness and Stress Reduction: Mindfulness practices, such as meditation, can help reduce cortisol levels and improve stress management. A meta-analysis of 45 studies found that all types of meditation lowered cortisol levels, reduced stress, and improved stress markers like blood pressure and heart rate.
• Deep Breathing: Slow, deep breathing techniques can reduce cortisol levels, improve your mood, and enhance cognition. Aim to practice deep breathing for 15 minutes daily, breathing slowly into your belly and inhaling/exhaling for a count of 8.
• Positive Social Connections: Spending time with friends and family who are willing to listen and provide support can help lower cortisol levels and improve mental and physical health. Sharing your problems with others can make them feel less overwhelming.
• Physical and Emotional Intimacy: Being physically and emotionally close to a romantic partner can help cope with stress and reduce cortisol responses. Even small gestures of intimacy, like a hug or a kiss, can be effective in stressful situations.
• Environment, Stress, and Circadian Rhythms: Spending time in nature and getting morning sunlight can help reduce cortisol levels. Exposure to natural light and darkness at the appropriate times helps maintain healthy circadian rhythms, which are crucial for regulating cortisol.
• Develop Healthy Routines: Establish consistent sleep and wake times, get natural sunlight, eat during daylight hours, and avoid artificial light at night. These healthy routines can lower cortisol levels, fix cortisol dysregulation, and improve metabolic health and sleep quality.
• Exercise: While exercise can temporarily elevate cortisol levels, it improves overall resistance to stress. Start with light to moderate exercise and gradually increase the intensity as you become more fit, which will improve your cortisol response.
• Diet: A balanced and nutritious diet that includes whole grains, fruits, vegetables, legumes, and healthy fats may help reduce cortisol levels. A diet high in added sugar and saturated fat is associated with higher cortisol levels.
• Limit Caffeine Intake: Caffeine can increase cortisol levels and disrupt sleep, so it's important to limit your intake, especially close to bedtime.
• Laughter: Laughing promotes the release of endorphins and suppresses stress hormones like cortisol. It improves mood, reduces stress, lowers blood pressure, and boosts the immune system.
• Sleep: Prioritize getting adequate, quality sleep as sleep deprivation can increase cortisol levels. Establish a bedtime routine and consistent sleep schedule to support healthy cortisol rhythms.

While these strategies can help manage cortisol levels, it's important to note that individual responses to stress vary. If you're concerned about your cortisol levels or are experiencing chronic stress, consider consulting a healthcare professional for personalized advice and guidance.
