Keto Diet: Why It Fails And How To Avoid It

The ketogenic diet is a high-fat, low-carbohydrate, and low-protein diet that has gained popularity in recent years. While some people have found success with the keto diet, reporting increased energy, mental clarity, and weight loss, others have found that it does not work for them and may even lead to weight gain and other negative side effects. There are several reasons why the keto diet may not work for everyone, including individual differences in insulin levels, gut health, thyroid function, and hormone production. Additionally, factors such as stress, sleep deprivation, and underlying medical conditions can also impact the effectiveness of the keto diet for weight loss.

The keto diet can worsen insulin metabolism and increase insulin resistance

The keto diet is a low-carb, high-fat diet plan that causes the body to burn fat instead of carbohydrates, a process known as ketosis. While some people claim that the keto diet has been a game-changer for their health and weight loss journey, it does not work for everyone.

A study conducted on mice by ETH Zurich and the University Children's Hospital Zurich found that keto diets don't allow the body to properly use insulin, so blood sugar isn't controlled properly. This leads to insulin resistance, which can raise the risk of type 2 diabetes. The researchers noted that their study did not evaluate the long-term effects of the keto diet, and more research is needed to understand fully how keto diets affect the body.

Another study, which reviewed different clinical trials, found that a ketogenic diet improved insulin sensitivity in individuals with type 2 diabetes. However, one study noted that while a ketogenic diet improved glycemic control, it created problems with lipid metabolism and the liver.

Therefore, while the keto diet may help some people with weight loss and improving their health, it can also worsen insulin metabolism and increase insulin resistance, especially in those who already have issues with insulin regulation.

The keto diet can cause an overgrowth of inflammatory compounds in the microbiome

The ketogenic diet is a high-fat, low-carbohydrate, and low-protein diet that has become a popular topic in recent years. While some people have found success with the keto diet, others have experienced the opposite effect, with their health and weight loss goals moving further away.

Research shows that when there is an overgrowth of "bad bugs" like LPS and other inflammatory compounds in the microbiome, diets rich in fat, such as the keto diet, work to pull the excess bugs out and into the blood, which are then transported and deposited throughout the body.

This increase in inflammation not only takes a toll on the body's overall functionality but can also make compliance with the diet difficult because inflammation is associated with cravings and a variety of mental health challenges.

Therefore, if you have digestive issues that are causing your gut bugs to dysfunction, the keto diet may not be the most effective diet for you because of its close associations with causing metabolic endotoxemia, increasing inflammation within the body, and increasing insulin resistance, among other issues.

The keto diet can cause hormonal imbalances and impact thyroid function

The keto diet is low in fibre, which is key for hormone balance. Fibre is found in starchy vegetables and grains, which are restricted on the keto diet. A lack of fibre can cause an increase in cortisol, the "stress" hormone. High cortisol levels can lead to weight gain and are associated with insulin resistance and pre-diabetes.

The keto diet can also lead to higher levels of estrogen, which can suppress thyroid function. Estrogen levels naturally rise during menopause, and the keto diet may further increase these levels, causing a further decline in thyroid activity. This can lead to a range of symptoms, including weight gain, heavier periods, and worse PMS.

In addition, the keto diet can affect the menstrual cycle and fertility. The strict macronutrient ratios and intermittent fasting required on the keto diet can put the body in a state of chronic stress, leading to cortisol spikes and suppressing the hormones that support fertility.

While the keto diet may help with hormone balance for some people, particularly those with PCOS or other hormone disorders, it can cause hormonal imbalances and impact thyroid function in others. It is important to be aware of the potential risks and side effects of the keto diet and to consult a healthcare professional before starting any new diet.

The keto diet can cause digestive issues

One of the main issues with the keto diet is its impact on gut health. Studies have shown that the keto diet increases the growth and movement of lipopolysaccharides (LPS), a type of inflammatory compound that exists within the gastrointestinal tract. Higher levels of LPS are associated with metabolic endotoxemia, which is when larger amounts of LPS are released into the bloodstream, causing inflammation throughout the body. This increase in inflammation can lead to cravings and mental health challenges, making it difficult to comply with the diet.

Additionally, the keto diet can cause digestive issues such as constipation and diarrhoea, especially during the early days of starting the diet. These symptoms are collectively referred to as "keto flu" and usually subside after a few weeks. However, if they persist, it may be a sign that the keto diet is not suitable for your body.

Furthermore, the keto diet restricts the consumption of starchy vegetables and grains, which are good sources of fibre. Fibre is essential for maintaining regular bowel movements and promoting a healthy gut microbiome. A lack of fibre in the diet can lead to constipation and other digestive issues.

The keto diet can also disrupt the balance of hormones, particularly in women. For example, diets high in fat can encourage estrogen production, which can suppress thyroid function. An efficiently functioning thyroid is crucial for weight loss and weight management as it controls hormonal and metabolic processes. Hormonal imbalances can lead to weight gain and impact overall health.

In conclusion, the keto diet can cause digestive issues and disrupt gut health, leading to inflammation and hormonal imbalances. These issues can hinder weight loss efforts and overall health. It is important to listen to your body and consult with a healthcare professional to determine if the keto diet is suitable for you.

The keto diet can increase cholesterol and lipid levels

The keto diet's impact on insulin can lead to an increase in cholesterol and lipid levels. When the body is in a state of ketosis, burning fat for energy instead of glucose, it becomes very efficient at breaking down fat. This can lead to an increase in cholesterol levels, as the body is breaking down more fat than it would on a regular diet. Additionally, the high-fat content of the keto diet can contribute to higher cholesterol levels.

The increase in cholesterol and lipid levels can be a concern for individuals with pre-existing health conditions or those who are at risk for developing heart disease. For these individuals, the keto diet may not be the best option for weight loss or improving health. It is important to consult with a healthcare professional before starting any new diet, especially one as restrictive as the keto diet.

Furthermore, the keto diet's restriction of carbohydrates and protein can also impact the body's ability to regulate cholesterol levels. Carbohydrates and protein are involved in the production of bile, which is needed for the digestion of fat and the absorption of cholesterol. By limiting the intake of these nutrients, the body may not have the necessary tools to properly regulate cholesterol levels, leading to an increase in cholesterol and lipid levels in the blood.

In addition to the direct impact on cholesterol and lipid levels, the keto diet can also increase the risk of metabolic endotoxemia. This is a condition where there is an increase in the growth and movement of Gram-negative bacteria called lipopolysaccharides (LPS) in the gastrointestinal tract. Metabolic endotoxemia is a significant cause of inflammation in the body, which can have negative effects on overall health and weight loss efforts.

While the keto diet has helped many people lose weight and improve their health, it is important to recognize that it may not be suitable for everyone. The impact on cholesterol and lipid levels is a potential concern, especially for individuals with pre-existing health conditions. Consulting with a healthcare professional and considering other dietary options, such as a low-carb diet, may be more appropriate for some individuals.
