The ketogenic diet is a high-fat, moderate-protein, and very low-carbohydrate diet. The diet aims to force the body to use a different type of fuel by reducing the intake of carbohydrates, which are the body's primary source of energy. On a keto diet, fat supplies as much as 90% of daily calories. While the keto diet allows you to eat a wide variety of tasty and nutritious meals, it is important to note that it is not a typical experiment or short-term dietary change. The diet has serious risks, including an increase in bad LDL cholesterol and nutrient deficiencies. Before starting the keto diet, it is recommended to consult a doctor and consider whether weight loss is necessary.
| Characteristics | Values |
|---|---|
| Meal frequency | Some people eat two meals a day while on the keto diet. |
| Meal composition | Meals should be high in fat and very low in carbohydrates. |
| Meal examples | Meat, poultry, fish, eggs, cheese, nuts, seeds, berries, non-starchy vegetables, and high-cocoa chocolate are all keto-friendly foods. |
| Caloric intake | In a 2,000-calorie diet, a keto meal might include 165 grams of fat, 40 grams of carbohydrates, and 75 grams of protein. |

Keto diet meal plans
The keto diet is a low-carb, high-fat, and moderate-protein diet. It is designed to force your body to use a different type of fuel. Instead of relying on glucose from carbohydrates, the keto diet relies on ketone bodies, which the liver produces from stored fat. This metabolic state is called ketosis.
The keto diet involves eating fat at every meal. On a 2,000-calorie diet, this could look like 165 grams of fat, 40 grams of carbs, and 75 grams of protein. However, the exact ratio depends on individual needs. It is important to note that the keto diet is associated with an increased risk of "bad" LDL cholesterol and heart disease due to its high saturated fat content.
- Lunch: Almond milk, peanut butter, spinach, cocoa powder, and stevia milkshake with sliced strawberries on the side.
- Main meal: A main protein like burger patties or steak, boiled or scrambled eggs, cheese, a big pepperami, strawberries, a leafy salad with dressing, and non-starchy vegetables like bell peppers, broccoli, or zucchini.
- Snacks: Meat, cheese, olives, boiled eggs, nuts, raw veggies, and dark chocolate.
- Restaurant meals: Meat-, fish-, or egg-based dishes with extra vegetables instead of carbs. For example, bun-less burgers with extra avocado, cheese, bacon, or eggs, or Mexican food with meat, cheese, guacamole, salsa, and sour cream.
It is important to rotate vegetables and meat over the long term to ensure a variety of nutrients and health benefits.

Keto-friendly foods
The ketogenic diet is a high-fat, moderate-protein, and very low-carbohydrate diet. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, about 5% to 10% of energy intake is from carbohydrates. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where the body uses fat for fuel instead of sugar.
Fish and Shellfish
Fish is protein-rich and carb-free. Salmon, sardines, mackerel, albacore tuna, and other fatty fish are high in omega-3 fats, which have been found to improve results for hemoglobin A1C, a test that measures blood sugar levels over three months. Shellfish is also keto-friendly, but the carb count varies by type.
Meat and Poultry
Meat and poultry are staple foods on the keto diet as they contain no carbs and are rich in B vitamins and minerals.
Eggs
Eggs are a great source of protein and are very keto-friendly.
Non-starchy Vegetables
Non-starchy vegetables are low in calories and carbs but high in nutrients, including vitamin C and several minerals. Broccoli, cauliflower, green beans, bell peppers, zucchini, spinach, kale, Swiss chard, collard greens, Brussels sprouts, asparagus, onions, garlic, and mushrooms are all good options.
Nuts and Seeds
Nuts and seeds are high in fat and low in carbs. They are also linked to a reduced risk of heart disease, certain cancers, depression, and other chronic diseases. Almonds, walnuts, and avocados are good choices.
Berries
Most fruits are too high in carbs for the keto diet, but berries can be consumed in small portions.
Dairy
Cheese, plain full-fat yogurt, cottage cheese, and unsweetened plant-based milk are all keto-friendly. However, dairy is high in saturated fat, which has been linked to an increased risk of heart disease, so it should be consumed in moderation.
It is important to note that the keto diet is not suitable for everyone and should be approached with caution. It is always a good idea to consult a healthcare professional before starting any new diet.

The science behind keto
The ketogenic diet, commonly known as the keto diet, is a low-carb, high-fat, and moderate-protein diet. The diet aims to force the body to use a different type of fuel for energy. Typically, carbohydrates from food are broken down into glucose, which is the body's main source of energy. However, when you reduce your carb intake, your body starts using fat as energy instead, turning it into substances called ketones. This process is called ketogenesis or ketosis. Ketosis usually begins about 3 to 4 days after starting a low-carb diet.
The keto diet is advertised as a weight-loss solution, but it is actually a medical diet that comes with certain risks. It was traditionally used in clinical settings to reduce seizures in children with epilepsy. Today, it is also used to help manage other neurological conditions, cancer, diabetes, PCOS (polycystic ovary syndrome), obesity, high cholesterol, and cardiovascular disease.
The keto diet involves eating healthy fats such as nuts (almonds, walnuts), seeds, avocados, tofu, olive oil, and some saturated fats like butter and coconut oil. It also includes moderate protein sources such as meat, poultry, and fish. Vegetables are an important part of the keto diet, but they are restricted to non-starchy, leafy greens like kale, spinach, broccoli, and bell peppers. Some fruits, usually berries, can be consumed in small portions.
While the keto diet has been shown to provide health benefits, it also has some risks. It is high in saturated fat, which has been linked to an increased risk of heart disease. The diet may also lead to nutrient deficiencies, especially in micronutrients like selenium, magnesium, phosphorus, and vitamins B and C. It is important to consult a doctor before starting the keto diet, as it may have side effects and is not suitable for everyone.

Health risks of keto
The keto diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, about 5% to 10% of energy intake is from carbohydrates. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where the body starts breaking down stored fat into molecules called ketone bodies to use for energy.
However, the keto diet also has potential health risks. Firstly, it is associated with an increased risk of heart disease due to its high content of saturated fats. The diet may also lead to nutrient deficiencies, as it restricts fresh fruits and vegetables, whole grains, and low-fat dairy, which are important sources of vitamins, minerals, and fiber. This can result in a lack of essential micronutrients such as selenium, magnesium, phosphorus, and vitamins B and C.
The keto diet could also negatively impact kidney health, as the high protein intake may overload the kidneys, which are responsible for metabolizing protein. Additionally, eating a lot of animal foods on the keto diet can lead to more acidic urine and a higher risk of kidney stones. The diet may also be difficult to maintain due to its restrictive nature, and it may not be suitable for everyone's lifestyle or preferences.
Furthermore, the keto diet has been linked to impaired bone health in several studies, with a potential decrease in bone mineral density. It is also important to note that the keto diet may increase the risk of low blood sugar events, especially in individuals with type 1 diabetes. As with any diet, it is essential to consult with a healthcare professional before starting, as they can advise on potential risks and adjustments based on individual needs.

Weight loss on keto
The ketogenic or "keto" diet is a low-carbohydrate, high-fat eating plan that has been proven to help people lose weight. The keto diet changes the way the body uses food by reducing the number of carbohydrates consumed and teaching the body to burn fat for fuel instead. This metabolic state is called ketosis.
The standard keto diet consists of 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates. The keto diet allows for the consumption of foods high in saturated fat, such as fatty cuts of meat, processed meats, lard, and butter, as well as sources of unsaturated fats, such as nuts, seeds, avocados, plant oils, and oily fish. The diet also includes non-starchy vegetables, which can be used as substitutes for high-carbohydrate foods, such as cauliflower rice or zucchini noodles.
The keto diet has been shown to be an effective weight-loss tool, with many people experiencing weight loss and increased energy while following the diet. The process of ketosis can help reduce feelings of hunger, which may lead to eating less food and promote weight loss. Additionally, the keto diet has been shown to be beneficial for people with Type 2 diabetes, as it can help manage blood sugar levels and lower the risk of developing cardiovascular disease.
However, it's important to note that the keto diet may not be suitable for everyone and can have some side effects. It is recommended to consult with a physician and a dietitian before starting the keto diet to ensure it is safe and to create a meal plan that is tailored to individual needs. Additionally, monitoring food so closely can lead to psychological distress and binge eating. For long-term weight loss, a balanced approach, such as the Mediterranean diet, is recommended by some experts.
