Keto Vitamins: Pros, Cons, And Effectiveness

The ketogenic diet has been around since the 1920s and was originally introduced as a method to treat epilepsy. In recent years, however, it has gained popularity as a weight loss tool. The keto diet is a low-carb, high-fat diet that aims to burn fat by cutting carbs. While the keto diet has been shown to be effective for weight loss, there are several potential pros and cons to consider.

Some of the pros of the keto diet include reduced hunger, larger initial weight loss, and improved blood sugar and insulin levels. Additionally, the keto diet may be therapeutic for a wide variety of disorders and diseases, including epilepsy, Alzheimer's, and type-2 diabetes. The diet may also boost energy levels and improve athletic performance.

On the other hand, some of the cons of the keto diet include its strict nature, which can make it difficult to sustain over a long period. The diet may also lead to unpleasant symptoms, such as nausea, headaches, and fatigue, commonly known as the keto flu. Nutritional deficiencies, dehydration, and digestive issues are also possible side effects of the keto diet. Furthermore, the high-fat nature of the diet could negatively impact heart health and increase the risk of kidney stones.

Overall, while the keto diet may offer several potential benefits, it is important to carefully consider the possible risks and side effects before starting this or any other diet. Consulting with a healthcare professional or registered dietitian is always recommended.

Keto can help with weight loss

The ketogenic diet is a low-carb, fat-rich eating plan that has been used for centuries to treat specific medical conditions. In the 19th century, it was commonly used to help control diabetes. The keto diet has also been used in closely monitored settings for cancer, diabetes, polycystic ovary syndrome, and Alzheimer's disease.

The keto diet has gained attention as a potential weight-loss strategy due to the low-carb diet craze, which started in the 1970s with the Atkins diet. Today, keto is distinctive for its exceptionally high-fat content, typically 70% to 80%, though with only a moderate intake of protein.

The premise of the keto diet for weight loss is that if you deprive the body of glucose, its main source of energy, an alternative fuel called ketones is produced from stored fat. The brain demands the most glucose, about 120 grams daily, and cannot store it. During fasting or very low carbohydrate intake, the body first pulls stored glucose from the liver and breaks down muscle to release glucose. If this continues for 3-4 days, blood levels of insulin decrease, and the body begins to use fat as its primary fuel.

When ketone bodies accumulate in the blood, this is called ketosis. Healthy individuals naturally experience mild ketosis during periods of fasting (e.g., sleeping) and strenuous exercise. Proponents of the keto diet state that if carefully followed, blood levels of ketones should not reach a harmful level, as the brain will use ketones for fuel, and healthy individuals will produce enough insulin to prevent excessive ketones.

A meta-analysis of 13 randomized controlled trials following overweight and obese participants for 1-2 years found that the keto diet produced a small but significantly greater reduction in weight, triglycerides, and blood pressure, and a greater increase in HDL and LDL cholesterol compared with a low-fat diet at one year.

A systematic review of 26 short-term intervention trials evaluated the appetites of overweight and obese individuals on either a very low-calorie or ketogenic diet using a standardized appetite scale. Despite losing a significant amount of weight on both diets, participants reported less hunger and a reduced desire to eat compared with baseline measures. The authors noted the lack of increased hunger despite extreme restrictions and theorized that changes in appetite hormones, ketone bodies, and increased fat and protein intakes were responsible.

Another study of 39 obese adults placed on a ketogenic very low-calorie diet for 8 weeks found a mean loss of 13% of their starting weight and significant reductions in fat mass, insulin levels, blood pressure, and waist and hip circumferences. Their levels of ghrelin, a hunger-stimulating hormone, did not increase while they were in ketosis, which contributed to a decreased appetite.

A study of 89 obese adults who were placed on a two-phase diet regimen (6 months of a very-low-carbohydrate ketogenic diet and 6 months of a normal-calorie Mediterranean diet) showed a significant mean 10% weight loss with no weight regain at one year.

Potential Drawbacks of Keto for Weight Loss

Following a very high-fat diet may be challenging to maintain. Possible symptoms of extreme carbohydrate restriction that may last days to weeks include hunger, fatigue, low mood, irritability, constipation, headaches, and brain fog. Staying satisfied with the limited variety of foods available and being restricted from otherwise enjoyable foods can present new challenges.

Some negative side effects of a long-term ketogenic diet have been suggested, including an increased risk of kidney stones and osteoporosis, and increased blood levels of uric acid (a risk factor for gout). Possible nutrient deficiencies may arise if a variety of recommended foods on the ketogenic diet are not included.

Who Should Not Try Keto?

The keto diet is not suitable for everyone. For example, it is not suitable for people with the following conditions:

• Disorders of fat metabolism
• Carnitine deficiency
• Pyruvate kinase deficiency
• Eating disorders
• Pancreatic disease
• Liver conditions
• Kidney disease
• Thyroid problems
• Gallbladder disease or those who have had their gallbladder removed
• Fat-malabsorption disorder

It may reduce blood sugar and insulin levels

The ketogenic diet is a high-fat, low-carbohydrate diet that has been around since the 1920s. It was initially introduced as a method to treat epilepsy in children and has since gained popularity as a weight loss tool. The diet typically consists of 5-10% calories from carbohydrates, 30-35% of calories from protein, and 55-60% of calories from fat.

One of the recognised pros of the keto diet is its potential to reduce blood sugar and insulin levels. This benefit is particularly relevant for people with diabetes and insulin resistance. Studies have shown that a low-carbohydrate diet can lead to greater improvements in glycemic control and medication reduction or elimination.

When carbohydrates are significantly reduced to a level of less than 50g per day, the body transitions to breaking down fat into ketones for energy. This process typically takes a few days. There are two metabolic processes that come into play when there is low carbohydrate availability: gluconeogenesis and ketogenesis.

Gluconeogenesis is the synthesis of glucose from non-sugar precursors such as lactate and pyruvate. When the availability of glucose drops even further, ketogenesis begins to provide an alternate source of energy in the form of ketone bodies, which replace glucose as the primary source of energy.

The Benefits for Diabetics

The keto diet has been found to be beneficial for people with type 2 diabetes due to its effectiveness in stabilising blood sugar levels. A 2019 study found that a keto diet reversed type 2 diabetes in some participants, and after a 2-year follow-up, many participants showed improvements in their diabetes blood markers.

However, it's important to note that the benefits seemed to decrease after 1 year, and many participants found it challenging to stick to the diet long-term. This suggests that a less restrictive and more sustainable eating plan may yield better long-term results for managing blood sugar and insulin levels.

Nutritional Considerations

While the keto diet can help reduce blood sugar and insulin levels, it's important to be mindful of potential nutritional deficiencies. The diet restricts certain food groups, including starchy vegetables, grains, and most fruits, which can make it challenging to obtain all the necessary vitamins and minerals.

Additionally, the body loses more water through urination during ketosis, and essential electrolytes such as sodium, potassium, and magnesium are excreted. It is crucial to ensure adequate intake of these minerals to maintain overall health and avoid side effects like fatigue, muscle cramping, and headaches.

In conclusion, while the keto diet may help reduce blood sugar and insulin levels, it is important to consult with a healthcare professional and monitor nutrient intake to avoid potential deficiencies.

It could be therapeutic for a wide variety of disorders

The ketogenic diet has been studied for its potential therapeutic effects on a wide variety of disorders and diseases. While more research is needed to confirm these effects, some preliminary findings are promising.

The ketogenic diet has been shown to be beneficial for patients with epilepsy, and it is still used as a treatment for this condition today. In recent years, there has been a surge of research on the potential benefits of the ketogenic diet for other disorders, including obesity, metabolic disorders, neurodegenerative diseases, autism spectrum disorder (ASD), Alzheimer's disease, glucose transporter 1 deficiency syndrome, and autoimmune multiple sclerosis (AIMS). Some research has even suggested that the ketogenic diet may be a promising support therapy for cancer patients when used in conjunction with modern cancer treatments like chemotherapy and radiation.

Additionally, the ketogenic diet has shown favourable results in stabilising blood sugar levels in patients with type-2 diabetes. This is because low-carb diets reduce blood sugar and insulin levels, which can benefit people with diabetes and insulin resistance.

While the research is still ongoing and more evidence is needed, the potential therapeutic effects of the ketogenic diet for a wide range of disorders and diseases are promising.

It may boost energy levels

The keto diet may lead to increased energy levels, according to some keto dieters. This is because the diet avoids significant peaks and valleys in blood sugar, resulting in a stable and steady supply of energy throughout the day. As a result, some dieters find that the keto diet helps them avoid energy dips and slumps.

The keto diet's high-fat nature could also contribute to increased energy levels. The body can enter a state of ketosis, where it burns fat for energy instead of carbohydrates. This provides a more stable and long-lasting source of energy compared to carbohydrates.

Additionally, the keto diet may improve mitochondrial function, which could lead to increased energy levels. The breakdown of fats for energy, called ketosis, can improve mitochondrial health and function.

However, it is important to note that the empirical evidence for increased energy levels on the keto diet is currently limited. While some individuals report feeling more energised, others may experience fatigue, especially during the initial transition phase known as the "keto flu."

To optimise energy levels on the keto diet, it is crucial to ensure adequate intake of certain nutrients. For example, magnesium is a mineral that boosts energy and regulates blood sugar levels. It may be challenging to obtain sufficient magnesium on a ketogenic diet, as many magnesium-rich foods like beans and fruits are also high in carbohydrates. Therefore, taking a magnesium supplement or including more low-carb, magnesium-rich foods in your diet can be beneficial.

Another supplement that may enhance energy levels on the keto diet is medium-chain triglycerides (MCTs). MCTs are quickly metabolised by the liver and provide a rapid source of fuel for the brain and muscles. MCT oil can be easily added to shakes and smoothies or taken by the spoonful.

In addition to supplements, maintaining adequate hydration is crucial for optimising energy levels on the keto diet. Dehydration is a common side effect of the keto diet due to increased urination during the transition to ketosis. Therefore, drinking plenty of water and getting adequate sleep can help reduce the severity of fatigue and other "keto flu" symptoms.

While the keto diet may boost energy levels for some individuals, it is important to note that everyone's experience may vary. The impact on energy levels can depend on various factors, including individual metabolism, dietary composition, and activity levels.

It can cause nutritional deficiencies

The keto diet is a high-fat, low-carbohydrate diet that can lead to nutritional deficiencies. This is because the diet restricts the consumption of certain food groups, such as fruits, vegetables, grains, and beans, which are rich sources of essential vitamins and minerals.

Firstly, the keto diet may result in a deficiency of vitamins and minerals commonly found in these food groups. For example, a keto diet is often low in vitamins A, E, and B6, as well as folate, calcium, magnesium, potassium, and iron. These nutrients are vital for various bodily functions, including proper vision, growth and development, immune system support, red blood cell formation, and nervous system health.

Secondly, the keto diet can lead to dehydration due to increased urination during the transition to ketosis. This dehydration can further deplete the body's electrolyte levels, particularly sodium, potassium, and magnesium, which are necessary for nerve and muscle function.

Thirdly, the restriction of high-fibre foods on the keto diet can result in digestive issues such as constipation. The high-fat content of the diet can also cause gastrointestinal distress, including nausea, diarrhea, cramping, bloating, and stomach upset.

Finally, the keto diet's emphasis on high-fat animal foods may increase the risk of developing kidney stones. This is because a high intake of animal products can make the blood and urine more acidic, leading to increased calcium excretion in the urine. Additionally, the keto diet may reduce the release of citrate, which binds to calcium and prevents kidney stone formation.

To mitigate these potential deficiencies, those on the keto diet are advised to include plenty of low-carbohydrate, nutrient-dense foods such as leafy greens, broccoli, asparagus, zucchini, and avocado. Consulting with a registered dietitian can also help ensure that individuals on the keto diet are meeting their nutritional requirements.
