The ketogenic diet, or keto diet, is a high-fat, low-carbohydrate eating plan designed to force the body to burn fat for energy instead of glucose, thereby achieving weight loss. While the keto diet has been used since the 1920s to reduce seizures in children with epilepsy, it has gained popularity as a weight-loss tool. The diet is associated with several benefits, including weight loss, increased energy, and the treatment of chronic illness. However, there are concerns about its long-term sustainability and potential health risks, such as increased cholesterol and dehydration. As with any drastic diet change, it is important to consult a healthcare professional before starting a ketogenic diet to ensure it is safe and appropriate for your individual needs.

What You'll Learn
Ketogenic diets and weight loss
The ketogenic diet is a low-carbohydrate, high-fat eating plan that has been used since the 1920s. It was initially introduced as a treatment for epilepsy in children. Today, it is widely recognised as a weight-loss tool.
The keto diet is based on cutting carbs and eating more fat. This shift in diet forces the body to use a different type of fuel. Instead of relying on glucose from carbohydrates, the keto diet utilises ketones, which are produced when the liver breaks down stored fat. To enter and remain in ketosis, individuals must consistently track their food intake, limiting carbohydrates to less than 50 grams per day. This often means excluding carb-rich foods like grains, beans, fruits, and starchy vegetables.
The ketogenic diet can be effective for weight loss, especially in the short term. Studies have shown that people can achieve faster weight loss with keto compared to calorie-reduction diets. However, maintaining the diet can be challenging, and weight regain is common once the diet is stopped. Ketogenic diets tend to decrease caloric intake, and some people may find it difficult to get enough nutrients, vitamins, minerals, and fibre. Additionally, adverse effects such as constipation, halitosis, muscle cramps, headaches, and diarrhoea are common.
Despite these challenges, some people find success with the keto diet. It can lead to reduced appetite and increased feelings of fullness due to the slower digestion of fats and proteins. This can result in lower overall food intake and contribute to weight loss. Furthermore, keto diets have been shown to improve insulin sensitivity, which can help regulate metabolism and decrease fat storage.
While the ketogenic diet can be a tool for weight loss, it may not be suitable for everyone. It is essential to carefully consider the potential benefits and drawbacks before starting any new diet. For long-term weight loss, a balanced approach like the Mediterranean diet is often recommended. This diet focuses on plant-based eating and allows for a varied and nutrient-dense meal plan.

Ketogenic diets and health risks
The ketogenic diet, popularly known as the keto diet, is a high-fat, low-carbohydrate diet. It is advertised as a weight-loss solution, but it is actually a medical diet that comes with serious risks. The keto diet is primarily used to manage seizures in children with epilepsy.
The keto diet is extremely strict and difficult to maintain. To achieve ketosis, the diet requires 75% of calories to come from fat, 5% from carbohydrates, and 15% from protein. This is a significant departure from a typical diet, where carbohydrates can make up as much as 55% of calories.
The keto diet has been linked to several health risks. Firstly, it can cause low blood pressure, kidney stones, constipation, nutrient deficiencies, and an increased risk of heart disease due to its high saturated fat content. It is not recommended for individuals with any conditions involving their pancreas, liver, thyroid, or gallbladder. Additionally, the keto diet can lead to social isolation and disordered eating due to its restrictive nature.
Furthermore, the keto diet may induce senescence, or aged cells, in normal tissues, particularly impacting heart and kidney function. However, an intermittent ketogenic diet with planned breaks did not exhibit these negative effects.
While the keto diet has shown benefits for weight loss, it is most effective when used in the short term, followed by the adoption of healthier eating habits. Without careful planning, individuals may experience weight regain once they stop the diet.
In conclusion, while the keto diet may offer weight-loss benefits, it also carries significant health risks and should be approached with caution. It is important to consult a healthcare professional before starting any new diet, especially one as restrictive as the keto diet.

Ketogenic diets and kidney health
Ketogenic diets have become increasingly popular for weight loss and the treatment of type 2 diabetes and obesity. However, there are concerns about their long-term effects, particularly regarding kidney health.
The ketogenic diet is a very low-carbohydrate, high-fat diet. It works by creating a state called "physiologic ketosis", where the body burns fat instead of carbohydrates for energy. While this can lead to weight loss, it can also have negative side effects, especially for those with underlying kidney issues.
One concern is that the diet can lead to dehydration, as it eliminates glycogen, which holds water, from the bloodstream. Dehydration can stress the kidneys and make underlying conditions worse. It can also lead to kidney stones and other kidney problems. A case study reported a 36-year-old female patient with no history of kidney problems who developed acute renal injury after starting a ketogenic diet.
The diet has also been associated with an increased risk of kidney stones in patients using it to treat epilepsy. Additionally, the high consumption of saturated fats may increase the risk of heart disease.
However, some studies suggest that ketogenic metabolic therapy (KMT) can be beneficial for individuals with chronic kidney disease (CKD). KMT is a medical nutrition therapy that addresses certain health and disease conditions. Since CKD is often caused by overnutrition leading to hyperglycemia, insulin resistance, and diabetes mellitus, the carbohydrate restriction in KMT may offer a therapeutic option. Some research indicates that KMT may improve renal function and could become a first-line therapy for certain CKD-associated conditions.
In conclusion, while ketogenic diets may be effective for weight loss and managing certain health conditions, they can also pose risks to kidney health. Dehydration, kidney stones, and potential worsening of underlying kidney conditions are all concerns. For those with kidney disease, a plant-based version of the diet may mitigate some of the risks associated with animal-based ketogenic diets. It is important to consult with a healthcare professional before starting any drastic diet, especially for those with existing health conditions.

Ketogenic diets and side effects
The ketogenic diet has been around since the 1920s and was initially developed to help reduce seizures in children with epilepsy. While it is still prescribed for that purpose, it has gained popularity in recent years as a weight-loss tool.
The keto diet is a high-fat, moderate-protein, and low-carbohydrate diet. It involves deriving 70-80% of calories from fat, 10-20% from protein, and 5-10% from carbohydrates. The diet restricts carb-rich foods like grains, beans, fruits, and starchy vegetables.
While the keto diet may lead to weight loss, it is not without its side effects and risks. Here are some of the potential side effects and drawbacks of the ketogenic diet:
- Keto Flu: During the initial phase of the keto diet, some people experience what is known as the "keto flu," which includes symptoms such as an upset stomach, headache, fatigue, dizziness, decreased energy, and mood swings. These symptoms are caused by the body's adaptation to ketosis, the metabolic state where the body burns fat for energy instead of glucose.
- Dehydration: The keto diet can lead to dehydration because it eliminates glycogen, which holds water, from the bloodstream. Dehydration can further contribute to kidney problems and the formation of kidney stones.
- Increased Cholesterol: The keto diet is associated with an increase in "bad" LDL cholesterol, which is a risk factor for heart disease and cardiovascular issues.
- Nutrient Deficiencies: The restriction of fruits, vegetables, whole grains, and low-fat dairy on the keto diet may lead to nutrient deficiencies.
- Social Isolation and Disordered Eating: The strict nature of the keto diet may cause social isolation, as well as psychological distress and disordered eating patterns.
- Not Sustainable: The keto diet may not be sustainable in the long term, and weight gain may return once a normal diet is resumed.
- Expense: Carbohydrates tend to be less expensive than keto staples like meat, fish, avocados, and high-fat dairy items.
- Health Risks: The keto diet can negatively affect kidney health, especially for those with pre-existing kidney disease. It may also increase the risk of heart disease due to the high consumption of saturated fats.
It is important to consult with a healthcare professional before starting the keto diet, as it may not be suitable for everyone. Additionally, working with a dietitian can help ensure the consumption of healthier types of fats and a proper understanding of the body's nutritional needs.

Ketogenic diets and food options
The ketogenic diet, or "keto" diet, is a low-carbohydrate, high-fat diet. Typically, 5% to 10% of energy intake on a keto diet comes from carbohydrates, with the remaining 70-75% coming from fat, 20-25% from protein, and the rest from other sources.
The keto diet is based on the principle that by limiting carbohydrates, the body will burn fat for fuel instead. This metabolic state is called ketosis, where the body breaks down stored fat into molecules called ketone bodies to use for energy.
The keto diet has been used since the 1920s and was originally prescribed to reduce seizures in children with epilepsy. Today, it is a popular weight-loss tool, with some research suggesting it may have benefits for blood sugar management, cancer treatment, and other health conditions.
Keto Food Options
The keto diet involves eating high-fat, low-carb foods, including:
- Animal proteins, such as beef, pork, and bacon, and fish
- Dairy, such as high-fat cheese, cream, and unsweetened almond or coconut milk
- Vegetables, particularly leafy greens like spinach, kale, Swiss chard, and collard greens
- Other plant-based foods, such as avocados, nuts, seeds, and olive oil
- Shirataki noodles, which are low in net carbs and calories
- Dark chocolate and cocoa, which are antioxidant-rich
It is important to note that the keto diet can be restrictive and challenging to maintain, and it may not be suitable for everyone. It is always recommended to consult a healthcare professional before starting any new diet, especially one as restrictive as keto.
