The ketogenic diet is a low-carbohydrate, high-fat diet that has been around since the 1920s. It was initially used to reduce seizures in children with epilepsy and is still prescribed for that purpose today. The diet is now also popular as a weight-loss tool, with some studies showing that people on low-carb diets lose more weight, faster, than those on low-fat diets. Other potential benefits of the ketogenic diet include increased energy, improved metabolic health, and reduced risk of certain diseases, including type 2 diabetes, heart disease, and cancer. However, the diet is not without its drawbacks, and some experts argue that it is not safe.

What You'll Learn
Weight loss
The ketogenic diet is a low-carbohydrate, high-fat diet that has been used since the 1920s. It has gained popularity as a weight-loss tool, with many studies showing its effectiveness in helping people lose weight.
The keto diet involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it burns fat for energy instead of glucose. Ketosis can help you feel less hungry, which may lead to eating less food and losing weight. The keto diet allows people to eat high-fat foods they enjoy, such as red meats, fatty fish, nuts, cheese, and butter, while still losing weight.
Research has shown that the ketogenic diet can lead to significant weight loss compared to low-fat diets. A meta-analysis of 11 studies found that individuals on a very low-carbohydrate ketogenic diet (VLCKD) experienced more considerable weight loss and improvements in metabolic parameters related to glycemic control and lipid control. Another study of 349 people with type 2 diabetes found that those on a ketogenic diet lost an average of 26.2 pounds (11.9 kg) over two years.
While the keto diet can be effective for weight loss, it may be challenging to stick to due to stringent food restrictions. It is also important to note that long-term weight loss depends on sustained caloric deficits and metabolic adaptation. Some people may experience weight regain once they stop the diet, and it is essential to consult a medical professional before starting any new diet.
Intermittent fasting is an approach that allows individuals to experience the benefits of ketosis while still eating a varied and balanced diet. This method involves cycling between periods of eating and fasting, with the fasting phase helping the body enter "mild ketosis." Intermittent fasting may be easier to maintain in the long term and can support metabolic health and weight management.

Improved blood sugar control
The keto diet has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term. This is because low-carb diets act to rid excess water from the body, lowering insulin levels and leading to rapid weight loss in the first week or two. Additionally, reducing carbohydrate intake is an effective way for diabetics to control their blood sugar levels since it reduces the error in determining the insulin amount needed to match their increased blood glucose levels.
For type 1 diabetics, a low-carbohydrate diet reduces the risk of dramatic spikes in blood sugar levels, making it easier to manage their condition. Furthermore, for type 2 diabetics, a diet that restricts carbohydrate consumption can improve or even eliminate their diabetic state. This is because type 2 diabetes results in insulin-resistant cells, which have been linked to other complications and atherosclerotic processes such as inflammation, decreased size of LDL particles, and endothelial dysfunction.
The benefits of improved blood sugar control through a ketogenic diet extend beyond diabetes management. Prior to the invention of insulin, diet was the main intervention used by diabetic patients, and physicians recommended a carbohydrate-free diet. By reducing carbohydrate intake, individuals can lower their risk of developing diabetes and improve their overall health.
While the ketogenic diet has shown promising results in improving blood sugar control, it is important to consult a medical professional before starting this or any other diet, as it may have side effects and is not suitable for everyone.

Reduced appetite
The ketogenic diet is a low-carbohydrate, high-fat diet that has been around since the 1920s. It was initially used to treat drug-resistant epilepsy in children and is still used for that purpose today. The diet is also touted as a weight-loss tool, as it changes the way the body uses food. Typically, carbohydrates in the diet provide most of the fuel the body needs. However, the keto diet reduces the number of carbs and teaches the body to burn fat for fuel instead. This metabolic state is called ketosis, where the body breaks down fats into molecules called ketones, which serve as an alternative fuel source.
One of the main benefits of the ketogenic diet is reduced appetite, which can lead to weight loss. When people cut carbs and eat more protein and fat, they tend to consume fewer calories. This automatic reduction in appetite is one of the simplest and most effective ways to lose weight. The keto diet is particularly effective at reducing belly fat while maintaining lean mass. People on low-carb diets lose weight faster than those on low-fat diets, even when the latter are actively restricting calories. This is because low-carb diets rid the body of excess water, lowering insulin levels and leading to rapid weight loss in the first week.
The keto diet helps people cut calories because it doesn't include many foods that people are likely to overeat. However, it can be challenging to transition off the keto diet without regaining weight, as people typically start eating more high-carb foods. To maintain a healthier weight once their goal is achieved, some data suggests transitioning to the Mediterranean diet or MIND diet.
While the keto diet can be effective for weight loss, it is hard to stick to due to stringent food restrictions. Baljash Singh Cheema, a cardiologist at Northwestern Medicine Bluhm Cardiovascular Institute, notes that the keto diet can be effective for weight loss when used in a short time period, followed by the adoption of healthier eating habits. However, studies have shown that once people stop the keto diet, they regain at least half of the weight they lost. Therefore, sustainable change over time is more important than rapid weight loss.
Although the keto diet can help reduce appetite and lead to weight loss, it is important to consult a medical professional before starting any new diet, especially a restrictive one like keto. Additionally, more research is needed to fully understand the long-term effects of the keto diet.

Epilepsy management
The ketogenic diet has been used since the 1920s to manage epilepsy, particularly in children. It involves a high-fat, low-carbohydrate, and controlled-protein regimen that produces ketones in the body, which serve as an alternative fuel source. This metabolic state, known as ketosis, forces the body to burn fat for energy instead of relying primarily on glucose from carbohydrates.
The ketogenic diet has proven effective in reducing seizures for some people with epilepsy, especially those whose seizures have not responded to medication. A clinical trial at Great Ormond Street Hospital in 2008 found that around 38% of children who started the ketogenic diet experienced reduced seizures and were able to decrease their anti-seizure medication. The diet has also been associated with other positive effects, such as increased alertness, awareness, and responsiveness in children.
While the ketogenic diet is typically recommended for children with epilepsy, adults may also benefit from this dietary treatment under the supervision of a trained medical specialist. The modified Atkins diet, a less restrictive variant, is often suggested for adults as it is easier to manage and adhere to.
It is important to note that the ketogenic diet is a medical treatment that should be carefully monitored by a physician and a dietitian. Providing information and training to patients and their families is crucial to ensure adherence to the diet, which can be challenging due to its stringent food restrictions. Additionally, a comprehensive evaluation, including laboratory tests, electroencephalogram (EEG), and brain MRI, is recommended before starting the diet to ensure its suitability for the patient.
Overall, the ketogenic diet has been shown to be a beneficial treatment option for epilepsy management, particularly for those who have not found relief through medication alone. However, it should be approached with caution and under the guidance of medical professionals to ensure safety and effectiveness.

Improved cardiovascular health
The ketogenic diet is a low-carbohydrate, high-fat diet. It has been shown to have a positive effect on cardiovascular health, specifically in the following ways:
Weight Loss
The keto diet is a popular tool for weight loss. When the body is in a state of ketosis, it burns fat instead of glucose for energy. This fat burning can lead to weight loss, which is beneficial for cardiovascular health.
Blood Pressure
The ketogenic diet has been shown to have a beneficial effect on blood pressure. High blood pressure is a risk factor for cardiovascular disease, so this improvement can reduce the risk of heart issues.
Cholesterol
Low-carb diets tend to be high in fat, which increases "good" HDL cholesterol. The higher the levels of HDL relative to "bad" LDL cholesterol, the lower the risk of heart disease. The keto diet can also reduce triglycerides, another type of fat molecule that increases the risk of heart disease.
Inflammation
The keto diet has strong anti-inflammatory properties, which can help with cardiovascular health. Inflammation is linked to atherosclerotic processes, which are associated with type 2 diabetes and insulin resistance.
Blood Sugar Control
The keto diet can improve blood sugar control, which is beneficial for those with diabetes. Type 2 diabetes is a risk factor for cardiovascular disease, so improving blood sugar control can have a positive impact on heart health.
