The ketogenic diet, commonly known as the keto diet, is a low-carbohydrate, high-fat eating plan that has been used to treat specific medical conditions since the 1920s. While it has been proven to reduce seizures in children with epilepsy, it has gained popularity as a weight-loss tool. The keto diet aims to force the body to use ketones, an alternative fuel source produced from stored fat, instead of glucose. While studies show that the keto diet can lead to rapid weight loss, there are concerns about its nutritional soundness and long-term sustainability. The stringent food restrictions may lead to nutrient deficiencies, and the high-fat nature of the diet has been associated with an increased risk of heart disease due to elevated bad LDL cholesterol levels. As such, it is recommended to consult with a physician and a dietitian before starting the keto diet to ensure it is nutritionally sound and safe for the individual.

What You'll Learn
Weight loss
The ketogenic diet, or keto, is a low-carbohydrate, high-fat eating plan that has been used for centuries to treat specific medical conditions. In the 19th century, it was used to help control diabetes. More recently, it has been used to treat epilepsy, 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. The premise of the ketogenic diet for weight loss is that if you deprive the body of glucose, the main source of energy obtained by eating carbohydrate-rich foods, an alternative fuel called ketones is produced from stored fat. When ketone bodies accumulate in the blood, this is called ketosis.
Research shows that the ketogenic diet may be effective for weight loss, especially in the short term. One review of 13 studies found that a ketogenic diet was slightly more effective for long-term weight loss than a low-fat diet. Another study of 34 older adults found that those on a ketogenic diet for 8 weeks lost nearly five times as much total body fat as those on a low-fat diet. A 2019 systematic review published in the American Journal of Clinical Nutrition found that a ketogenic diet can lower markers of inflammation, which is associated with a decreased risk of heart disease. A 2020 study published in Circulation also demonstrated that a ketogenic diet could reduce low-density lipoprotein (LDL) cholesterol levels, a significant risk factor for heart disease.
However, there are some concerns about staying on a keto diet long-term. It is a restrictive diet, and it can be difficult to sustain. Once a normal diet is resumed, the weight is likely to return. Dr. Baljash Singh Cheema, a cardiologist at Northwestern Medicine Bluhm Cardiovascular Institute, states that "the ketogenic diet can be effective for weight loss when used in a short time period followed by the adoption of healthier eating habits. However, we know in studies of these types of diets that once people stop following that diet, they regain at least half of the weight that they lost. Sustainable change over time is far more important."
Additionally, the keto diet is associated with an increase in "bad" LDL cholesterol, which is linked to heart disease. It can also change the water and mineral balance in the body, so adding extra salt to meals or taking mineral supplements may be necessary. It is recommended that anyone considering the keto diet consult with a physician and a dietitian to closely monitor any biochemical changes and create a meal plan that is tailored to their existing health conditions and nutritional needs.

Nutritional deficiencies
The ketogenic diet is a low-carbohydrate, high-fat diet that has been used to treat specific medical conditions since the 1920s. It has been proven to reduce seizures in children with epilepsy and is now also used as a weight-loss tool. While the keto diet can be nutritionally sound, it is associated with some nutritional deficiencies.
The keto diet is restrictive, and as a result, people may not receive the nutrients, vitamins, minerals and fibres that they would usually get from fresh fruits, legumes, vegetables and whole grains. For example, the keto diet is associated with a low intake of omega-3 fats, vegetables, fruits and fibre. This low fibre intake can lead to chronic constipation, while inadequate magnesium, vitamin C and potassium can contribute to muscle cramps, fatigue and weakened immune function.
The keto diet is also associated with an increase in "bad" LDL cholesterol, which is linked to heart disease. Dr Cheema, a cardiologist at Northwestern Medicine Bluhm Cardiovascular Institute, notes that the high-fat nature of the diet could have negative impacts on heart health. However, some studies have found that the keto diet can lower markers of inflammation, which is associated with a decreased risk of heart disease.
Due to the risk of nutritional deficiencies, it is recommended that individuals consult with a physician and a dietitian before starting the keto diet. This will allow them to closely monitor any biochemical changes and create a meal plan that is tailored to their health needs.

Health benefits
The Ketogenic diet, or keto diet, is a low-carbohydrate, high-fat diet. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called nutritional ketosis, where the body uses fat for fuel instead of sugar (glucose). This produces acids known as ketones.
There are several health benefits associated with the keto diet.
Weight Loss
The keto diet is well known for its ability to aid weight loss. Research suggests that the keto diet helps people cut calories because the diet doesn't include many foods that people are likely to overeat. Studies have shown that the keto diet can lead to rapid and sustained weight loss in individuals with obesity for up to two years.
Management of Type 2 Diabetes
The keto diet can help manage type 2 diabetes. A study compared the effects of a low-calorie (LC) diet vs a very low-carbohydrate ketogenic diet (VLCKD) on health outcomes for type 2 diabetics. The VLCKD group approached normal blood sugar levels in just 24 weeks, and reduced insulin doses by half, on average.
Management of Epilepsy
The keto diet has been used since the 1920s as a treatment for pediatric drug-resistant epilepsy to reduce seizures. It is still used today to help prevent seizures when medications alone are not enough.
Heart Health
A systematic review found that a ketogenic diet can lower markers of inflammation, which is associated with a decreased risk of heart disease. Additionally, a study published in 2020 showed that a low-carbohydrate, high-fat ketogenic diet could reduce low-density lipoprotein (LDL) cholesterol levels, a significant risk factor for heart disease.
Nutrition
A well-formulated ketogenic diet can provide a low-carbohydrate intake while delivering adequate fiber sources such as seeds, nuts, coconut, avocado, spinach, broccoli, cauliflower, and berries. These rich pre-biotic foods would lead to an increase in Bacteroides and Bifidobacterium and a subsequent decrease in Firmicutes.

Side effects
The ketogenic diet is a low-carbohydrate, high-fat diet that has been used to treat specific medical conditions. It was introduced in 1920 as a treatment for epilepsy in children. Today, it is commonly used as a weight-loss strategy.
While the ketogenic diet can be nutritionally sound, it has some side effects that should be considered before starting this diet. Firstly, the keto diet is extremely strict and challenging to maintain. It restricts the consumption of fresh fruits and vegetables, whole grains, and low-fat dairy, which can lead to nutrient deficiencies.
Secondly, the high-fat nature of the diet can have negative impacts on heart health. The diet is associated with an increase in "bad" LDL cholesterol, which is a risk factor for heart disease. The American Heart Association recommends limiting saturated fat intake to less than 6%, while the keto diet can provide up to 90% of daily calories from fat.
Additionally, the keto diet can cause constipation due to the lack of fiber. It can also lead to an increased risk of kidney stones and osteoporosis, as well as increased blood levels of uric acid, which is a risk factor for gout.
When starting the keto diet, some people experience what is called the "keto flu," with symptoms such as an upset stomach, dizziness, decreased energy, and mood swings. This is caused by the body's adaptation to ketosis, the metabolic state where the body burns fat for fuel instead of glucose.
It is important to consult a doctor and a registered dietitian before starting the ketogenic diet to ensure it is safe and to monitor any biochemical changes.

Long-term sustainability
The ketogenic diet has been around since the 1920s, when it was introduced as a treatment for epilepsy in children. Today, it is primarily touted as a weight-loss tool, with many studies showing that this type of diet can help people lose weight. However, long-term compliance with the ketogenic diet can be challenging due to its stringent food restrictions. The diet is low in carbohydrates and high in fat, with fat supplying up to 90% of daily calories. This means that carb-rich foods like grains, beans, fruits, and starchy vegetables are excluded.
The high-fat nature of the ketogenic diet has raised concerns about its impact on heart health. The diet is associated with an increase in "bad" LDL cholesterol, which is a risk factor for heart disease. However, some studies have found that the diet can lower markers of inflammation, which is associated with a decreased risk of heart disease. The American Heart Association recommends limiting saturated fat intake to less than 6%, but the keto diet does not discriminate between lean protein foods and protein sources high in saturated fat.
Another concern with the keto diet is that it may not provide all the necessary nutrients. By restricting carbohydrates, the diet may also limit the intake of fresh fruits, legumes, vegetables, and whole grains, which are good sources of vitamins, minerals, and fiber. To address this concern, it is recommended that individuals consult with a physician and a dietitian before starting the keto diet to ensure they are meeting their nutritional needs.
While the keto diet has been shown to be effective for weight loss, it is best to make this a short-term dietary change to jumpstart weight reduction. Studies have shown that once people stop the diet, they tend to regain at least half of the weight they lost. Therefore, sustainable change over time is more important than short-term dietary restrictions.
In conclusion, while the ketogenic diet may be nutritionally sound in the short term, there are concerns about its long-term sustainability due to its restrictive nature and potential negative impacts on heart health. It is important for individuals to consult with a healthcare professional before starting the keto diet to ensure it is safe and appropriate for their needs.
