Review of the Ketogenic Diet for Losing Weight

What is Ketogenic Diet it?

The ketogenic diet, sometimes known as the "keto" diet, is a low-carb, high-fat diet that has been utilised for centuries to treat particular medical disorders. The ketogenic diet was frequently used to manage diabetes in the 19th century. It was first presented in 1920 as a successful treatment for epilepsy in kids who were not responding to medicines. For the treatment of diabetes, polycystic ovarian syndrome, Alzheimer's disease, and cancer, the ketogenic diet has also been studied and utilised in carefully controlled conditions.

However, the low-carb diet trend that began in the 1970s with the Atkins diet has made this diet a possible weight-loss technique that is receiving a lot of attention (a very low-carbohydrate, high-protein diet, which was a commercial success and popularised low-carb diets to a new level).

Today's Paleo, South Beach, and Dukan diets are all rich in protein but low in fat, as are other low-carb eating plans. The ketogenic diet, in contrast, stands out for its extraordinarily high fat content, which ranges from 70% to 80%, despite only having a small intake of protein.

How Ketogenic Diet Work? 

The idea behind the ketogenic diet for weight loss is that by denying the body of glucose—the primary source of energy for all cells in the body, which is gained by ingesting carbohydrate foods—ketones, a substitute fuel, are created from stored fat (thus the name "keto"-genic"). Because it cannot store glucose, the brain requires the most of it consistently, roughly 120 grammes per day. When fasting or very little carbohydrate is consumed, the body first releases glucose by temporarily destroying muscle and releasing glucose that has been stored in the liver. The body starts to burn fat as its main fuel if this goes on for three to four days and all of the stored glucose is used up. Blood levels of the hormone insulin also fall during this time.

              Ketone bodies, which the liver makes from fat and can be utilised in the absence of glucose, are produced.

Ketosis is the condition that occurs when ketone bodies build up in the blood. When fasting (such as sleeping through the night) or engaging in really rigorous activity, healthy individuals naturally experience moderate ketosis. The brain will use ketones as fuel, and healthy people normally make enough insulin to prevent excessive ketones from accumulating, according to proponents of the ketogenic diet, so blood levels of ketones should not reach a hazardous level (known as "ketoacidosis") if the diet is strictly adhered to. Various factors, including body fat percentage and resting metabolic rate, influence how quickly ketosis occurs and how many ketone bodies build up in the blood.

Ketoacidosis, or an overabundance of ketone bodies, can result in a blood acidity level that is poisonous and hazardous. As a result of the kidneys starting to expel ketone bodies and body water in the urine during ketoacidosis, some fluid-related weight loss occurs. People with type 1 diabetes are more likely to experience ketoacidosis because they do not produce insulin, a hormone that stops the overproduction of ketones. Ketoacidosis, however, has been documented to happen in a few extremely rare instances in non-diabetic people who have been on a long-term, very low carbohydrate diet.

 

The Ketogenic Diet 

There is no "standard" ketogenic diet with a certain macronutrient ratio (carbohydrates, protein, fat). The average daily total carbohydrate intake for people following the ketogenic diet is less than 50 grams—the equivalent of one medium plain bagel—and can even be as low as 20 grammes. Popular sources for the ketogenic diet typically advise consuming 70–80% of the daily caloric intake as fat, 5–10% as carbohydrates, and 10–20% as protein. This equates to around 165 grammes of fat, 40 grammes of carbohydrate, and 75 grammes of protein for a 2000 calorie diet. Because consuming too much protein can hinder ketosis, the ketogenic diet keeps its protein intake moderate in comparison to other low-carb high-protein diets. A ketogenic diet works because the amino acids in protein can be converted to glucose.

Although the ketogenic diet comes in several forms, all of them prohibit carbohydrates. Foods like bread, cereal, pasta, rice, biscuits, potatoes, corn, and other starchy vegetables, as well as fruit juices, are examples of foods that include both refined and whole grain carbohydrates. Beans, legumes, and most fruits are among those that might not be as noticeable. The majority of ketogenic diets permit foods high in saturated fat, including fatty meat cuts, processed meats, lard, and butter, as well as unsaturated fat sources, including nuts, seeds, avocados, plant oils, and oily fish. Ketogenic food lists might vary and even dispute depending on your information source.

     

              Programs advise following a ketogenic diet up until the targeted weight loss. Once this is done, the diet can be followed for a few days a week or a few weeks a month, with other days allowing for increased carbohydrate intake. This will help avoid weight gain.

   The Early Research

Short-term metabolic improvements brought on by the ketogenic diet have been demonstrated. Along with weight loss, health conditions linked to being overweight—such as insulin resistance, high blood pressure, and abnormally high cholesterol and triglycerides—have improved. [2,7] The use of low-carbohydrate diets for type 2 diabetes, such as the ketogenic diet, is increasingly gaining popularity. Although not always supported by data, there are a number of theories as to why the ketogenic diet aids in weight loss: [2,8,9]. 

• Due to the high fat content of the diet, a satiating effect with reduced hunger pangs was observed.
• a reduction in the hormones that cause hunger, such as ghrelin and insulin, when consuming low carbohydrate levels.
• Ketone bodies, the body's primary fuel source while on a diet, have a direct function in lowering hunger.
• increased calorie expenditure brought on by the metabolic consequences of turning protein and fat into glucose.

Reduced insulin levels have been linked to the promotion of fat loss over lean body mass.

 Potential Problems

It could be difficult to maintain a diet that is extremely heavy in fat. Hunger, exhaustion, a bad mood, irritability, diarrhoea, headaches, and "brain fog" are all potential signs of acute carbohydrate restriction that could last days to weeks. Though these uneasy sensations might pass, it might be harder to keep full with the little selection of foods available and to avoid things that you might usually love, such a crisp apple or a creamy sweet potato.

Long-term adherence to a ketogenic diet may have some drawbacks, such as an increased risk of kidney stones, osteoporosis, and elevated uric acid levels in the blood (a risk factor for gout). If a variety of meals on the ketogenic diet are not consumed, it may result in potential nutrient deficiencies. To ensure adequate intakes of fibre, B vitamins, and minerals (iron, magnesium, and zinc)—nutrients typically found in foods like whole grains that are restricted from the diet—it is important to focus on a variety of foods each day from the permitted meats, fish, vegetables, fruits, nuts, and seeds rather than just eating high-fat foods. Due to the exclusion of whole food categories, guidance from a trained dietitian may be helpful in developing a ketogenic diet that minimises nutrient deficiencies.

As a result

There is still little information on the ketogenic diet's effectiveness for weight loss. The majority of the studies conducted thus far had a small number of participants, were brief (12 weeks or fewer), and lacked control groups. Some people have been shown to experience short-term advantages from a ketogenic diet, such as weight loss and improvements in total cholesterol, blood sugar, and blood pressure. When compared to the results of standard weight loss regimens, these outcomes after a year are not significantly different.

Compliance may be challenging due to the elimination of a number of food groups and the possibility of unpleasant symptoms. A focus on foods high in saturated fat also goes against advice from the American Heart Association and the Dietary Guidelines for Americans and may have negative impacts on blood LDL cholesterol. However, it is possible to alter the diet to prioritise items low in saturated fat, such as olive oil, avocado, nuts, seeds, and fatty fish.

Some individuals who have had trouble reducing weight using traditional approaches may want to consider a ketogenic diet. Depending on an individual's genetic make-up and body composition, a specific ratio of fat, carbohydrate, and protein may be required to attain health advantages. Therefore, if someone decides to begin a ketogenic diet, it is advised to speak with their doctor and a dietitian in order to closely monitor any biochemical changes that occur after beginning the regimen, to create a meal plan that is customised to their current health conditions, and to avoid nutritional deficiencies or other health complications. Upon achieving weight loss, a dietitian may also offer advice on how to resume eating carbohydrates.

A modified carbohydrate diet based on the Healthy Eating Plate model may result in sufficient health benefits and weight loss in the general population.
