Keto And Low Sex Drive: Is There A Link?

The ketogenic diet is a very low-carbohydrate, high-fat, and moderate-protein eating plan. The popularity of the diet has led many to wonder how it impacts various things beyond weight loss, including one's sex drive. Some people on the keto diet experience a dip in libido, followed by a surge in their sex drive. Research isn't conclusive, but high-fat diets are usually linked to higher sex hormones, which can increase sexual desire.

The keto diet can cause a temporary energy dip, affecting your sex drive

The keto diet can cause a temporary energy dip, which may affect your sex drive. This is because carbohydrates are the body's main source of energy. When someone starts the keto diet, they may experience a drastic drop in energy due to a lack of carbohydrates, which could, in turn, affect their sex drive.

The body breaks down digestible carbohydrates into glucose, which enters the bloodstream. As blood sugar rises, the pancreas produces insulin, a hormone that allows cells to absorb sugar. The body then produces the hormone glucagon, which helps keep blood sugar and energy levels stable. Simple carbohydrates, such as cane sugar and high-fructose corn syrup, cause blood sugar to spike more rapidly than slower-moving complex carbohydrates, which are found in starchy vegetables and whole grains. This spike can cause blood sugar to fall rapidly, leading to a "groggy, crashing feeling" and a loss of energy.

When someone first starts the keto diet, their body switches from using carbohydrates for energy to burning fat because they are not eating carbs. This can make people feel very tired and unwell, which may result in a low sex drive.

However, this energy dip is temporary. Once the body grows accustomed to the lack of carbs, there is usually a subsequent increase in sex drive, likely due to the increase in fat.

Carbohydrates are the body's main source of energy, but they can also work against your energy levels

Carbohydrates are indeed the body's main source of energy. They are macronutrients found in certain foods and drinks, including sugars, starches, and fiber. When you eat carbohydrates, your body breaks them down into glucose, or blood sugar, which is then absorbed into your bloodstream and used by your cells for energy.

However, not all carbohydrates are created equal. Simple carbohydrates, such as sugars, are quickly broken down by the body, leading to spikes in blood sugar and energy levels. On the other hand, complex carbohydrates, like starches and fiber, take longer to digest, resulting in more stable blood sugar and energy levels.

Simple carbohydrates can work against your energy levels by causing spikes and crashes in blood sugar. Consuming too many simple carbohydrates can lead to weight gain and increase the risk of diabetes, heart disease, and high cholesterol. Additionally, a very low-carbohydrate diet can also negatively impact your energy levels. A drastic reduction in carbohydrate intake can lead to a drop in energy, as carbohydrates are the body's primary fuel source. This can leave you feeling tired and fatigued, affecting your overall energy levels and ability to perform daily tasks.

Furthermore, carbohydrates play a crucial role in the production of serotonin, the "happy hormone." A lack of carbohydrates can decrease serotonin levels, leading to low mood and decreased energy levels.

It is important to note that while carbohydrates are essential for energy, a balanced diet that includes other macronutrients like healthy fats and proteins is crucial for maintaining optimal energy levels.

Low-fat diets can lead to drops in female sex hormones

Low-Fat Diets and Drops in Female Sex Hormones

Low-fat diets can have a significant impact on female sex hormones, as evidenced by several studies. One study found that women who consumed a low-fat diet, with only 20% of their calories from fat, experienced a notable reduction in estrogen levels. This can lead to a low sex drive, vaginal dryness, and disruptions in sleep and mood.

A different study revealed that a low-fat diet can also lead to decreases in two other crucial female sex hormones: estradiol and testosterone. Estradiol plays a vital role in female sexual desire, while testosterone, though typically associated with males, is essential for estrogen production and libido in women.

The link between low-fat diets and female sex hormones was further supported by a study involving 33 healthy women. The participants were randomly assigned to either a standard diet (40% fat) or a low-fat diet (20% fat) for two months, followed by a switch to the alternative diet for another two months. The results indicated that the low-fat diet decreased levels of non-protein-bound estradiol and non-protein-bound testosterone in premenopausal women.

Additionally, low-fat diets have been associated with reduced cholesterol levels, which are significantly linked to estradiol, testosterone, and dehydroepiandrosterone.

While the direct impact of low-fat diets on female sex hormones is evident, it is worth noting that other factors, such as overall calorie intake, stress levels, and exercise, also play a role in hormonal balance.

High-fat diets can improve testosterone levels in men

Testosterone is a sex hormone that affects bone and muscle health and blood cell production. Testosterone levels decline as you age, but other factors such as certain medications, high body fat levels, and some health conditions can also cause low testosterone.

Low testosterone, also called hypogonadism or low T, occurs when testosterone levels fall below 300 nanograms per decilitre. Symptoms of low testosterone include decreased spontaneous erections, reduced testicular size, and reduced bone and muscle mass.

A 2021 review of six studies found that low-fat dietary patterns were associated with decreased testosterone levels compared with higher-fat dietary patterns. Another study confirmed that low-fat diets could drop testosterone levels by as much as 12%, while high-fat diets may increase testosterone levels by 13%.

For men, drops in testosterone can lead to low sex drive and erectile dysfunction, as well as decreased energy levels, muscle mass, and hair loss.

In addition to the amount of fat in the diet, the type of fat consumed also makes a difference. While monounsaturated and polyunsaturated fats can improve your sex drive, the fatty trans fat found in fried foods does not. Trans fat can lead to abnormal sperm production in men.

It is important to note that while a high-fat diet can improve testosterone levels, other factors such as body weight and lifestyle habits can also affect testosterone levels. Maintaining a moderate weight and a healthy lifestyle that includes physical activity, avoiding smoking, and reducing alcohol and drug use can help improve testosterone levels.

In conclusion, high-fat diets can indeed improve testosterone levels in men, which can have a positive impact on their overall health and well-being, including sexual health.

A well-balanced keto diet can reduce inflammation and balance hormones

The ketogenic diet is a high-fat, adequate-protein, and low-carbohydrate diet that causes the body to enter a state of ketosis, where it burns fat for energy instead of carbohydrates. This shift in metabolism has been shown to have numerous health benefits, including reduced inflammation and improved hormonal balance.

Reducing Inflammation

Inflammation is a major cause of pain, both chronic and acute. Research suggests that the ketogenic diet can effectively reduce inflammation, making it a promising approach for pain management. In rodent studies, the diet has been found to reduce inflammatory pain and spontaneous pain behaviours.

The anti-inflammatory effects of the ketogenic diet are attributed to its ability to reduce the production of free radicals and enhance antioxidant mechanisms. By lowering inflammation, the diet may help manage conditions such as diabetic neuropathy, chemotherapeutic neuropathy, gout, rheumatoid arthritis, inflammatory bowel disease, and fibromyalgia.

Balancing Hormones

The ketogenic diet can also help balance hormones, particularly sex hormones, and improve related symptoms. Here's how:

• Increased Estrogen: High-fat diets have been found to increase estrogen levels, which is especially beneficial for women approaching menopause. Low estrogen levels can lead to a reduced sex drive, vaginal dryness, and mood disturbances.
• Improved Estradiol and Testosterone: The ketogenic diet can help regulate estradiol and testosterone levels, which are key for female sexual desire and fat distribution. Testosterone is also important for estrogen production and muscle strength.
• Weight Loss: The ketogenic diet promotes weight loss, which can help postmenopausal women regulate their hormone levels. Excess weight can lead to the overproduction of certain hormones, negatively impacting libido.
• Improved Insulin Sensitivity: By reducing carbohydrate intake, the ketogenic diet improves insulin sensitivity. Insulin is a master hormone that controls blood sugar levels, and when it's out of balance, sex hormone levels can drop. Improved insulin sensitivity can also lead to easier weight management and a reduced risk of cardiovascular disease and dementia.
• Detoxification: A plant-based ketogenic diet includes vegetables like broccoli, cauliflower, and greens, which help detoxify toxic forms of estrogen found in the environment. These environmental estrogens can worsen PMS symptoms and increase the risk of breast cancer, endometriosis, fertility issues, and autoimmune diseases.
• Combating PCOS: Polycystic ovary syndrome (PCOS) is a common cause of fertility issues in women, and it is often associated with poor hormonal balance and obesity. The ketogenic diet has been found to improve insulin and testosterone levels in women with PCOS, leading to improvements in weight, fertility, and menstruation.
• Reduced Stress: The ketogenic diet, rich in low-carbohydrate vegetables, can help normalize cortisol levels, support adrenal glands, and improve natural progesterone levels. High cortisol levels due to chronic stress can interfere with sex hormone balance and increase the risk of high blood sugar and low libido.

In summary, a well-balanced ketogenic diet can effectively reduce inflammation and balance hormones, particularly sex hormones. By improving hormonal balance, the ketogenic diet can enhance libido and alleviate symptoms associated with hormonal imbalances, such as weight gain, hot flashes, low energy, and mood swings.
