Weight loss
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. The diet aims to force the body into using a different type of fuel. Instead of relying on glucose (sugar) that comes from carbohydrates, the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat. This metabolic state is called ketosis.
Ketosis occurs when the body burns fat for energy instead of glucose. Ketosis can be identified through blood, urine, and breath tests that measure the amount of ketones produced by the body. Symptoms of ketosis include increased thirst, dry mouth, frequent urination, and decreased hunger or appetite.
The keto diet is advertised as a weight-loss wonder, and it has been shown to produce beneficial metabolic changes in the short term. However, it is best to make this only a short-term dietary change to jump-start weight reduction. Once a normal diet is resumed, the weight will likely return.
The keto diet can be an effective way to lose weight without counting calories or tracking food intake. It has been shown to be slightly more effective for long-term weight loss than a low-fat diet. One 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. Another study in 34 older adults found that those on the keto diet for 8 weeks lost nearly five times as much total body fat as those on a low-fat diet.
The keto diet's high-fat content can have a satiating effect, reducing food cravings and decreasing appetite-stimulating hormones such as insulin and ghrelin. The ketone bodies produced during ketosis may also play a direct role in reducing hunger.

Improved metabolic health
The ketogenic diet is a low-carbohydrate, high-fat, and moderate-protein diet that induces a metabolic state called ketosis, where the body uses fat as its primary fuel source instead of carbohydrates. Ketosis is characterised by higher ketone levels in the blood, lower blood sugar levels, and improved insulin sensitivity.
Ketone bodies, often referred to as a "super fuel", produce more ATP than glucose. This means that ketones enable the body to maintain efficient fuel production even when experiencing a caloric deficit. Additionally, ketone bodies can reduce free radical damage and enhance the body's antioxidant capacity.
The keto diet has been found to improve clinical markers of disease risk in individuals with metabolic syndrome, insulin resistance, and type 2 diabetes. It can enhance glucose control through reduced glucose intake and improved insulin sensitivity. The diet can also help with weight reduction, particularly in abdominal obesity, and improve blood pressure, blood glucose regulation, triglyceride levels, and HDL cholesterol levels.
Recent research indicates potential benefits in reducing the risk of certain diseases, including type 2 diabetes, hyperlipidemia, heart disease, and cancer. The ketogenic diet has also been found to improve intestinal barrier function and reduce the production of ROS and free radicals.

Reduced risk of certain diseases
The ketogenic diet is a low-carb, high-fat, and moderate-protein diet. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts the body in a metabolic state called ketosis, where it burns fat for energy instead of glucose.
While the keto diet is often associated with weight loss, some evidence suggests that it may also reduce the risk of certain diseases. Firstly, the keto diet has been linked to a reduction in seizure frequency in some individuals with drug-resistant epilepsy. Additionally, the diet can lower blood glucose levels, which may be beneficial for those with type 2 diabetes. However, it is important to note that the keto diet is not suitable for individuals with type 1 diabetes due to the associated risks of elevated ketone levels and complications in the brain, kidney, liver, and microvasculature.
The keto diet's restriction of carbohydrates may also reduce the risk of cancer, as high-carb diets have been linked to an increased risk of certain cancers. However, the keto diet's emphasis on red meat, processed meat, and saturated fats may potentially increase the risk of other cancers.
Furthermore, the keto diet may reduce the risk of Alzheimer's disease. The state of ketosis, which is a key feature of the keto diet, has been associated with improved cognitive function and brain health.
While the keto diet may offer some potential benefits in reducing the risk of certain diseases, it is important to consult a healthcare professional before starting any new diet, especially one as restrictive as keto. Additionally, the keto diet has been associated with an increased risk of other conditions, such as heart disease and kidney disease, so a comprehensive understanding of the risks and benefits is essential.

Lower blood sugar and insulin levels
The keto diet is a low-carb, high-fat diet that can help lower blood sugar and insulin levels. Typically, carbohydrates in your diet provide most of the fuel your body needs. The keto diet reduces the number of carbs you eat and teaches your body to burn fat for fuel instead.
When your body has fewer carbs to burn for energy, it burns fat instead. As your body breaks down fat, it produces a compound called ketones, or ketone bodies, which become your body and brain's main source of energy. The keto diet aims to force your body into using this different type of fuel.
Ketogenic diets improve insulin sensitivity through their effects on fat and weight loss. The severe restriction of digestible carbohydrates in the keto diet reduces insulin secretion, leading to decreased lipogenesis, increased lipolysis, and higher blood levels of ketone bodies. Lower insulin levels mean a lower insulin-to-glucagon ratio. The insulin required to metabolize a ketogenic meal is almost ten times less than that needed to metabolize a Mediterranean diet meal.
The keto diet may be particularly beneficial for people with diabetes. It may help manage blood sugar levels and reduce the need for insulin medication. However, it is important to note that unmanaged diabetes may increase the risk of DKA (diabetes ketoacidosis), a life-threatening condition that requires immediate medical attention.

Endurance training
The ketogenic diet has become popular among endurance athletes as a performance enhancer. It is thought to provide a steady supply of energy for the body and brain during prolonged exercise and accelerate recovery time post-exercise. However, there is limited and heterogeneous evidence regarding the efficacy of the endurance athlete's ketogenic diet (EAKD) for performance benefit.
The ketogenic diet prescribes a significant reduction in carbohydrate intake, which facilitates physiological changes that promote the utilization of ketones. Ketosis is not disruptive to training if the body has been trained to use fat as its primary source of fuel. This means that the absence of carbohydrates is not a problem.
To stay in ketosis, athletes would need to restrict their total daily carb intake to under 30 grams, with none of this coming from simple sugars. This can be achieved by doing a weekly fasted workout, warming up fasted, and reverting to a ketogenic diet after workouts. This will ensure that the body continues to produce ketones.
There are several types of ketone drinks available on the market, such as Ketone mono-ester, C6 Ketone Di-ester, Ketone salts, and Butanediol. These drinks are thought to provide an extra energy boost to power the muscles and improve performance. However, it is important to note that the benefits of ketone drinks will vary according to the use protocol, exercise challenge, and athlete characteristics.
While the ketogenic diet may be suitable for endurance athletes, it may not be ideal for high-intensity bursts of activity. It could also impair muscle growth and reduce energy levels, especially during high-intensity physical activity. Therefore, it is recommended to stick to low-intensity, steady-state activities during the workout to maximize the potential benefits of the ketogenic diet.
