Keto Diet: Unraveling The Paradox Of Its Efficacy And Unhealthiness

The keto diet is a low-carb, high-fat diet that has gained popularity for its ability to produce quick weight loss. While it has been shown to be effective for weight loss and even the reduction of seizures in epileptic children, it is not without its risks. The keto diet can lead to nutrient deficiencies, digestive issues, impaired bone health, and an increased risk of chronic diseases and early death. It is also associated with an increase in bad LDL cholesterol, which can lead to heart disease. As such, it is important to consult a doctor and a registered dietitian before starting the keto diet to ensure that it is safe for your individual needs and health status.

The keto diet may lead to nutrient deficiencies

The keto diet is a low-carb, high-fat diet that can lead to weight loss and provide other health benefits. However, it is associated with several risks, including nutrient deficiencies.

The keto diet restricts several food groups, including fruits, whole grains, legumes, starchy vegetables, and high-carb fruits. These foods are typically rich in essential vitamins and minerals, and their exclusion from the diet may lead to deficiencies over time.

Some studies suggest that the keto diet may not provide enough calcium, vitamin D, magnesium, phosphorus, folate, thiamin, and vitamins A, B, C, E, and K. These nutrients are essential for various bodily functions, including bone health, metabolism, and immune function.

For example, magnesium is crucial for muscle and nerve function, blood sugar control, and blood pressure regulation. A deficiency in magnesium can lead to symptoms such as muscle cramps, fatigue, and irregular heartbeat.

Similarly, calcium is essential for bone health and muscle function. A calcium deficiency can increase the risk of osteoporosis, a condition that weakens the bones and makes them more prone to fractures.

Vitamin C, another nutrient that may be lacking in the keto diet, is important for immune function, collagen formation, and iron absorption. A deficiency in vitamin C can lead to scurvy, a disease characterized by fatigue, joint pain, and bleeding gums.

To mitigate the risk of nutrient deficiencies, it is important to carefully plan meals and ensure adequate intake of nutrient-rich keto-friendly foods. These include avocados, nuts, seeds, and non-starchy vegetables. Additionally, seeking guidance from a dietitian or healthcare professional before starting the keto diet is recommended.

While the keto diet can be effective for weight loss and offer certain health benefits, it is important to be aware of the potential risks, including nutrient deficiencies, and take appropriate measures to minimize them.

It can cause digestive issues

The keto diet can cause digestive issues and changes in gut bacteria. The diet restricts carbohydrates, making it difficult to meet your daily fibre needs. As a result, the keto diet can lead to digestive discomfort, constipation, and diarrhea.

A 10-year study in children with epilepsy found that 65% reported constipation as a common side effect. In addition, fibre feeds the beneficial bacteria in the gut, and a low-carb, low-fibre diet like keto may negatively affect gut bacteria.

Some keto-friendly foods that are high in fibre include flax seeds, chia seeds, coconut, broccoli, cauliflower, and leafy greens. However, it is important to note that the keto diet can be challenging to follow long-term due to its restrictive nature.

To minimize digestive issues, it is recommended to start with a regular low-carb diet for a few weeks to allow the body to adjust to burning more fat before completely eliminating carbs. Additionally, staying hydrated and increasing electrolyte intake can help with constipation.

It may increase the risk of chronic diseases and early death

The ketogenic diet's impact on an individual's risk of chronic illness, such as heart disease or cancer, is a hotly contested topic that is not fully understood. While the keto diet is linked to weight loss and other health benefits in the short term, it may lead to long-term health issues.

Some evidence suggests that high-fat, low-carb diets that focus on animal foods may lead to poor health outcomes. A long-term observational study of over 130,000 adults linked animal-based low-carb diets to higher rates of death from heart disease, cancer, and all causes. On the other hand, vegetable-based low-carb diets were associated with a lower rate of death from heart disease and all causes.

Another study of over 15,000 adults found similar results but linked both low and high-carb diets to a greater all-cause death rate, compared to moderate-carb diets where carbs comprised 50-55% of total daily calories.

The keto diet is associated with an increased "bad" LDL cholesterol, which is linked to heart disease. The diet's high saturated fat content can also lead to heart disease.

While research is mixed, some evidence suggests that low-carb diets that focus on animal foods may lead to higher death rates from heart disease, cancer, and all causes.

Due to these risks, individuals with kidney disease, diabetes, heart or bone ailments, or other medical conditions should speak to their healthcare provider before trying the keto diet.

It could be unsustainable and lead to weight gain

The keto diet is advertised as a weight-loss wonder, but it is actually a medical diet that comes with serious risks. While it can be used to help reduce the frequency of epileptic seizures in children, it is best to make this only a short-term dietary change to help jump-start weight reduction.

The keto diet is unsustainable for several reasons. Firstly, it is extremely strict and difficult to maintain. It requires eating 75% of calories from fat, 5% from carbohydrates, and 15% from protein. This means cutting out fresh fruits and vegetables, whole grains, and low-fat dairy, which can help with long-term weight loss and overall health. The diet is also costly, as it includes expensive foods like red meats and nuts.

Secondly, the keto diet can be dangerous to health. It can lead to low blood pressure, kidney stones, constipation, nutrient deficiencies, and an increased risk of heart disease. It could also cause social isolation or disordered eating. The diet is not safe for those with any conditions involving their pancreas, liver, thyroid, or gallbladder.

Thirdly, the keto diet can cause side effects while the body adjusts, known as the "keto flu". These include upset stomach, dizziness, decreased energy, and mood swings.

Finally, critics of the keto diet say that most of the lost weight is water weight, and that once the body enters ketosis, it begins to lose muscle and eventually enters starvation mode, making it even harder to lose weight.

For these reasons, the keto diet may be unsustainable and lead to weight gain. It is important to consult a doctor and a registered dietitian before attempting this diet.

The keto diet may cause low blood pressure

The keto diet is a low-carb, high-fat diet that is often used for weight loss. It involves restricting carbohydrate intake to force the body to use fat for energy instead of carbohydrates. While the keto diet can be effective for weight loss, it also has some potential risks and side effects, including low blood pressure.

The keto diet aims to force the body into a state of ketosis, where it uses ketone bodies (a type of fuel produced by the liver from stored fat) instead of glucose (sugar from carbohydrates) for energy. To achieve ketosis, individuals on the keto diet typically limit their carbohydrate intake to fewer than 50 grams per day. This can be challenging as even a medium-sized banana contains about 27 grams of carbohydrates.

The keto diet has been shown to have a lowering effect on blood pressure, especially in individuals with hypertension (high blood pressure). This effect is likely due to weight loss and improvements in other cardiovascular risk factors such as inflammation, cholesterol levels, and insulin function. However, there are a few potential risks and side effects to be aware of when following the keto diet:

• Medication interactions: If you are taking blood pressure medication and start the keto diet, you may experience low blood pressure as the diet can further lower your blood pressure. It is important to monitor your blood pressure and consult your doctor if you experience symptoms of low blood pressure, such as feeling weak, tired, or dizzy.
• Salt and bouillon: The keto diet may increase urinary sodium loss, leading to low sodium levels. To minimize early side effects, it is often recommended to consume extra fluid and salt, such as bouillon, during the first two weeks of the diet. However, if your blood pressure is high despite medication, you should avoid extra salt or bouillon as it may further increase your blood pressure.
• Dirty keto: A "dirty keto" diet, which is high in processed meat and low in vegetables, may be short on potassium. This can lead to an imbalance between sodium and potassium levels, which can raise blood pressure.
• Low sodium: Low-carb diets can also lead to low sodium levels, as the body releases a hormone called aldosterone to retain sodium. This can also raise blood pressure.

Tips to improve blood pressure:

• Exercise: Regular mild to moderate aerobic exercise can help lower blood pressure.
• Sleep: Short sleep and sleep disorders are independent risk factors for high blood pressure.
• Weight loss: Losing weight can help improve blood pressure.
• Sodium and potassium: Getting enough sodium and potassium is important for maintaining healthy blood pressure.
• Fiber: Increasing fiber intake may help lower blood pressure.
