Keto Diet: Testosterone Boosting Benefits For Men

The ketogenic diet is a popular, low-carb, high-fat diet that puts your body in a state of ketosis, or fat-burning mode. There is evidence to suggest that the keto diet can increase testosterone levels in men. Testosterone is a steroidal hormone, which means it is synthesized from cholesterol, a fatty substance. The keto diet increases the amount of cholesterol in the blood, which can then increase testosterone production. Several studies have shown that the keto diet can boost testosterone levels, especially when paired with exercise. However, it is important to note that increasing cholesterol levels may have negative impacts on heart health, and more research is needed to fully understand the effects of the keto diet on testosterone levels.

Keto can increase testosterone levels in obese men

The ketogenic, or keto, diet is a low-carb, high-fat diet that puts your body in a state of ketosis, or "fat-burning mode". The diet is designed to limit carbohydrate consumption to under 50 grams per day, or about 5% of your energy intake, while also keeping protein consumption to a moderate to high level, at about 1.2 to 1.5 grams per kilogram of body weight per day. The remaining 80% of energy consumption comes from fats.

Keto and Testosterone

Testosterone is the primary sex hormone in males. It is responsible for encouraging the development of primary and secondary male sex characteristics, as well as playing a key role in sex drive, muscle growth, and fat metabolism. Testosterone is a steroidal hormone, which means it is synthesized from cholesterol, a fatty substance.

When on a keto diet, the increased consumption of dietary fat can increase the amount of cholesterol in the blood, which can, in turn, increase testosterone production. This theory has been supported by scientific studies, which have shown that a high-fat diet like keto can boost testosterone levels.

One study, in particular, found that college-aged men who followed a ketogenic diet and resistance training program saw a significant increase in their total testosterone levels compared to those on a traditional "Western" diet. Additionally, a very low-calorie ketogenic diet (VLCKD) has been shown to rapidly improve testosterone levels in non-diabetic obese subjects, with significant increases observed after 7 and 28 days on the diet.

Keto, Weight Loss, and Testosterone

Obesity and hypogonadism are bi-directionally correlated, with a higher prevalence of hypogonadism in the obese population. Weight loss has been shown to increase testosterone serum levels, and the keto diet can be an effective tool for weight loss. By following a keto diet, obese men can not only lose weight but also potentially increase their testosterone levels, particularly if they are experiencing obesity-related hypogonadism.

Keto, Insulin, and Testosterone

High blood sugar and insulin resistance are correlated with low testosterone levels. The keto diet can help lower blood sugar and increase insulin sensitivity, which has a positive impact on testosterone. When the body is in a state of ketosis, it burns fat instead of glucose, reducing blood sugar levels. This, in turn, improves insulin sensitivity, as the body's cells become more responsive to insulin, resulting in lower blood sugar and higher testosterone levels.

While keto alone may not instantly fix low testosterone levels, it can be a valuable component of a comprehensive approach to improving testosterone levels. In addition to keto, other lifestyle factors such as exercise, adequate sleep, and stress reduction are important. For obese men, in particular, the keto diet can be an effective tool for weight loss and increasing testosterone levels, especially when paired with exercise and other healthy habits. However, it is important to consult with a healthcare professional before starting any new diet, as keto may not be suitable for everyone.

Testosterone is a steroidal hormone synthesised from cholesterol

Testosterone is a critical hormone for several physiological functions, including reproduction, weight, mood, and sex drive. It is also important for growing bone and muscle cells and burning fatty acids in the blood. Men have about 15 times as much testosterone in their bodies compared to females, as it also helps with sperm production.

Testosterone is a steroid hormone that sends messages to cells. It is derived from cholesterol in the testicular Leydig cell under the control of the pituitary gonadotropin LH. Unlike most cells that use cholesterol primarily for membrane synthesis, steroidogenic cells have additional requirements for cholesterol as it is the essential precursor for all steroid hormones.

The cholesterol utilised for testosterone synthesis is derived from a combination of sources:

• De novo synthesis in the endoplasmic reticulum (ER)
• Mobilisation of cholesteryl esters (CEs) stored in lipid droplets through cholesteryl ester hydrolase
• Plasma lipoprotein-derived CEs obtained by either LDL receptor-mediated endocytic and/or SR-BI-mediated selective uptake
• In some cultured cell systems, from plasma membrane-associated free cholesterol

Keto can increase cholesterol levels

The ketogenic or "keto" diet is a high-fat, low-carbohydrate, and moderate-protein diet. Typically, 10% of daily calories are derived from carbohydrates, 30% from protein, and 60% from fat. The diet triggers a process called "ketosis", where the body uses fat instead of carbohydrates for energy.

There is a concern that the keto diet may cause a spike in cholesterol levels, which could increase the risk of heart disease. This is a valid concern, as the diet includes a high amount of fat, and meeting the fat quota may include unhealthy choices such as butter, coconut oil, and animal fat. These are all sources of saturated fat, which has been linked to poor heart health by the American Heart Association (AHA).

Research has found that a low-carbohydrate, high-fat (LCHF) diet almost doubled the risk of cardiovascular events when compared to a standard diet. During the study, 9.8% of participants on an LCHF diet experienced a cardiovascular event, including blockage in arteries, a heart attack, or stroke, compared to 4.3% in the control group. Participants on LCHF diets also had significantly higher LDL cholesterol levels and apolipoprotein B (ApoB), a protein that indicates high cholesterol levels.

However, the effect of keto on heart health is not as clear-cut as it may seem. According to Daniel Soffer, MD, an internist and lipidologist at Penn Medicine, research shows that keto produces modest reductions in triglycerides, modest changes in heart-protective high-density lipoprotein (HDL, or "good" cholesterol), and minimal changes in low-density lipoprotein (LDL, or "bad" cholesterol). Some studies show an increase in LDL on low- or very-low-carb diets, while others show a decrease or no change.

The impact of keto on LDL cholesterol is influenced by the quality of the diet and individual genetic factors. If a keto diet includes a high amount of saturated fat, it is likely to increase LDL cholesterol. Additionally, those with an inherited genetic mutation that affects LDL regulation may experience a significant increase in LDL levels when following a keto diet.

Therefore, while keto can increase cholesterol levels, particularly LDL cholesterol, the effect is dependent on the specific details of the diet and individual genetic factors. It is important to consult a doctor before adopting a keto diet, especially for those with high cholesterol or other health conditions.

Keto can improve body composition

The ketogenic diet is a low-carb, moderate protein, and high-fat diet. It works for almost anyone, including vegans and vegetarians, as it focuses on eating foods that are naturally high in fat and avoiding highly processed foods.

Weight Loss

A ketogenic diet can be very useful for reducing body fat. A 2013 study comparing the ketogenic diet to a low-fat diet revealed that the former is more effective for weight loss. Another study compared the effectiveness of a low-carb keto diet to a low-fat diet among obese men and women. The researchers concluded that the low-carb keto diet was effective for short-term weight and fat loss, particularly in men.

Reducing Health Risks

Several studies have shown that a very low-carbohydrate ketogenic diet (VLCKD) has been shown to reduce the risk of the following:

• Cardiovascular disease
• Cancer and tumor progression
• Polycystic ovary syndrome
• Neurological diseases such as Parkinson's and Alzheimer's
• Amyotrophic lateral sclerosis

Muscle Mass

A ketogenic diet has been shown to be effective in preserving muscle mass. A study on people who underwent radiotherapy revealed that a self-administered ketogenic diet helped preserve muscle mass despite weight loss. However, keto may not work for someone looking to gain body weight by increasing lean body mass or for competitive athletes.

Energy Levels

A ketogenic diet trains your body to rely on dietary fat for energy by converting fat to ketones and free fatty acids (FFAs). This natural metabolic state is often referred to as ketosis. Reaching ketosis means you have to limit your carb intake to encourage your body to produce ketones for energy. Unlike glucose, which provides quick bursts of energy, the energy from fat burns slower. As a result, you may avoid sugar crashes right after a high-carb meal when on a keto diet.

Appetite Suppression

A ketogenic diet also helps curb overeating, since unsaturated fats are more satiating.

Keto can increase insulin sensitivity

The ketogenic diet is a low-carbohydrate, high-fat diet that has been shown to aid weight loss and treat other health concerns. It has been found to be effective in suppressing seizure activity in children with epilepsy and is commonly used to control symptoms of type 2 diabetes.

Keto diets induce a metabolic state called ketosis, where cells that would usually get their energy from glucose, switch to ketones. This metabolic state can be maintained long-term and has been found to improve insulin sensitivity.

Research has shown that insulin resistance improves promptly for most people who begin a ketogenic diet. This is due to the ketones produced, not just the reduced intake of carbohydrates. If an individual loses weight, insulin resistance can be further reduced. The degree to which insulin sensitivity is maintained long-term depends on the individual. Factors such as the duration of insulin resistance and physical activity levels may play a role in an individual's level of carbohydrate tolerance.

In a study on rats, it was found that maintenance on a ketogenic diet resulted in decreased sensitivity to peripheral insulin and impaired glucose tolerance. However, these effects were rapidly reversed upon cessation of the diet. Another study on obese, non-diabetic men found that a very low-calorie ketogenic diet resulted in rapid improvements in testosterone levels, associated with weight loss.

Overall, while keto diets have proven effective in tackling obesity and improving insulin sensitivity, more research is needed to fully understand the underlying mechanisms and long-term effects.
