The ketogenic diet is a low-carb, high-fat diet that aims to force the body into using fat for energy instead of carbohydrates. While it is advertised as a weight-loss wonder, it is actually a medical diet that comes with serious risks and is not suitable for everyone. The keto diet is highly restrictive and involves limiting your daily carbohydrate intake to 20-50 grams, which is significantly less than the average diet. This means cutting out high-carb foods such as grains, legumes, fruits, starchy vegetables, and sugar. Instead, you eat high-fat foods such as meat, fish, eggs, nuts, seeds, oils, and some dairy products.
There are several versions of the keto diet, including the standard ketogenic diet, the cyclical ketogenic diet, the targeted ketogenic diet, and the high-protein ketogenic diet. The standard keto diet is the most researched and recommended version.
While the keto diet can lead to weight loss and has potential benefits for certain health conditions, it also has several side effects and may not be suitable for everyone. It is important to consult a doctor or dietitian before starting the keto diet to ensure it is safe for you and to help you create a plan that meets your nutritional needs.

The keto diet is a high-fat, low-carb, moderate-protein diet
The keto diet is a very low-carb, high-fat diet that shares similarities with Atkins and low-carb diets. It 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 carbohydrates.
The standard ketogenic diet (SKD) is the most researched and recommended version of the keto diet. It typically contains 70% fat, 20% protein, and only 10% carbs.
On the keto diet, you can eat meat, fish, eggs, nuts, healthy oils, avocados, and low-carb veggies. It's important to base your diet on whole, single-ingredient foods.
Foods to Eat on the Keto Diet:
- Meat: red meat, steak, ham, sausage, bacon, chicken, and turkey
- Fatty fish: salmon, trout, tuna, and mackerel
- Eggs: pastured or omega-3 whole eggs
- Butter and cream: grass-fed butter and heavy cream
- Cheese: unprocessed cheeses like cheddar, goat, cream, blue, or mozzarella
- Nuts and seeds: almonds, walnuts, flaxseeds, pumpkin seeds, chia seeds, etc
- Healthy oils: extra virgin olive oil and avocado oil
- Avocados: whole avocados or freshly made guacamole
- Low-carb veggies: green veggies, tomatoes, onions, peppers, etc
Foods to Avoid on the Keto Diet:
- Sugary foods: soda, fruit juice, smoothies, cake, ice cream, candy, etc
- Grains or starches: wheat-based products, rice, pasta, cereal, etc
- Fruit: all fruit, except small portions of berries like strawberries
- Beans or legumes: peas, kidney beans, lentils, chickpeas, etc
- Root vegetables and tubers: potatoes, sweet potatoes, carrots, parsnips, etc
- Low-fat or diet products: low-fat mayonnaise, salad dressings, and condiments
- Alcohol: beer, wine, liquor, mixed drinks
The keto diet has been shown to have health benefits, including weight loss, improved risk factors for heart disease, and potential benefits for certain cancers and Alzheimer's disease. However, it may not be suitable for everyone and can have side effects such as increased cholesterol levels and constipation.
It's important to consult a doctor or dietitian before starting the keto diet to ensure it is safe and appropriate for your individual needs and health goals.

The keto diet puts the body into a metabolic state called ketosis
The keto diet is a low-carb, high-fat diet that puts the body into a metabolic state called ketosis. Ketosis is when the body starts burning fat for energy instead of carbohydrates. This is achieved by drastically reducing the intake of carbohydrates, limiting the body's supply of glucose (its primary energy source).
When the body is in ketosis, it becomes very efficient at burning fat for energy. It also turns fat into ketones in the liver, which can be used by the brain for energy. Ketogenic diets can cause significant reductions in blood sugar and insulin levels, which can have various health benefits.
To reach ketosis, the daily intake of carbohydrates should be limited to around 20 to 50 grams. This can be achieved by eating meat, fish, eggs, nuts, and healthy oils, as well as some low-carb vegetables and fruits. It is important to monitor protein intake as well, as too much protein can slow down the transition into ketosis.
The keto diet has been shown to have several health benefits, including weight loss, improved insulin sensitivity, and reduced risk of heart disease, cancer, and Alzheimer's disease. However, it is important to note that the keto diet can be restrictive and may cause side effects such as constipation, "keto flu," and fuzzy thinking. It is not suitable for everyone, and those with chronic health conditions should consult a doctor or dietitian before starting the keto diet.

The keto diet is used to treat epilepsy and aid weight loss
The keto diet is a low-carb, high-fat diet that has been used to treat epilepsy and aid weight loss. It involves drastically reducing carbohydrate intake and replacing it with fat, which puts the body into a metabolic state called ketosis. This reduction in carbs forces the body to burn fat for energy instead of carbohydrates, which can lead to weight loss. The diet typically limits carbs to 20-50 grams per day and includes foods such as meat, fish, eggs, nuts, seeds, and non-starchy vegetables.
The keto diet has been found to be effective for weight loss, with research showing that it may be as effective as a low-fat diet. It has also been shown to improve risk factors for heart disease, including lowering body fat, increasing HDL (good) cholesterol levels, and reducing blood pressure. Additionally, the keto diet has been used to treat epilepsy, with studies showing significant reductions in seizures in epileptic children.
However, the keto diet is not suitable for everyone and may have some side effects. It is very restrictive and can be challenging to follow. It may also lead to an increased risk of heart disease due to the high levels of saturated fat. Other potential risks include nutrient deficiencies, liver and kidney problems, constipation, and fuzzy thinking. Therefore, it is important to consult a doctor or dietitian before starting the keto diet to ensure it is safe and suitable for your individual needs.

The keto diet has several variations, including the standard ketogenic diet, cyclical ketogenic diet, targeted ketogenic diet, and high-protein ketogenic diet
The standard ketogenic diet (SKD) is a very low-carb, moderate-protein, and high-fat diet, typically consisting of 70% fat, 20% protein, and 10% carbs. This is the most researched and recommended version of the keto diet.
The cyclical ketogenic diet (CKD) involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days. This version is popular among those seeking muscle growth and improved exercise performance.
The targeted ketogenic diet (TKD) is designed for athletes looking to improve their performance. It involves following the standard keto diet and adding carbs around workouts to fuel the body and aid in recovery.
The high-protein ketogenic diet is similar to the standard ketogenic diet but includes more protein. The ratio is typically 60% fat, 35% protein, and 5% carbs. This version may be suitable for bodybuilders and older adults wanting to prevent muscle breakdown.
While the standard and high-protein ketogenic diets have been extensively studied, the cyclical and targeted ketogenic diets are more advanced methods primarily used by bodybuilders and athletes.
Regardless of the variation chosen, the keto diet involves consuming a very low amount of carbohydrates and replacing them with healthy fats. This dietary approach can lead to weight loss and offer potential health benefits, such as lowering the risk of certain diseases.

The keto diet has several risks and side effects and should be followed under medical supervision
The keto diet has been linked to several health benefits, including weight loss, improved blood sugar control, and reduced risk of chronic illnesses. However, it's essential to be aware of the potential risks and side effects before considering this diet. Here are some reasons why the keto diet should be followed under medical supervision:
- Risk of kidney problems: The keto diet includes a high intake of animal foods like eggs, meat, and cheese, which can increase the acidity of your blood and urine, leading to an increased risk of kidney stones. People with chronic kidney disease should avoid this diet as it can worsen their condition.
- Digestive issues and gut health: The keto diet restricts carbohydrates, making it challenging to meet daily fiber needs. This can lead to digestive issues such as constipation and may negatively impact gut health by reducing beneficial bacteria in the gut.
- Nutrient deficiencies: The keto diet restricts nutrient-dense foods like fruits, whole grains, and legumes, which may result in deficiencies of essential vitamins and minerals over time. Some studies suggest that the keto diet may not provide enough calcium, vitamin D, magnesium, and phosphorus.
- Low blood sugar: While the keto diet can help manage blood sugar levels in people with diabetes, it may also increase the risk of dangerously low blood sugar levels, especially in individuals with type 1 diabetes who are taking insulin.
- Bone health: The keto diet has been associated with impaired bone health in several studies. It may reduce bone mineral density and trigger bone breakdown, increasing the risk of fractures.
- Chronic diseases and early death: There is conflicting evidence regarding the impact of the keto diet on the risk of chronic illnesses and early death. Some studies suggest that high-fat, low-carb diets focusing on animal foods may lead to poor health outcomes, while those emphasizing vegetable sources of fats and proteins provide benefits.
- Keto flu: As your body transitions to using ketones and fat for fuel, you may experience the "keto flu," which includes symptoms like headaches, dizziness, fatigue, nausea, and constipation. These side effects usually improve within a few weeks, but it's important to monitor them and stay hydrated.
- Micronutrient deficiencies: Long-term adherence to the keto diet may lead to deficiencies in specific micronutrients, such as potassium, sodium, magnesium, calcium, and vitamins B, C, and E.
- High cholesterol: The keto diet may cause an increase in LDL ("bad") cholesterol levels, which could potentially lead to accelerated atherosclerosis and an increased risk of cardiovascular disease.
- Sustainability and compliance: The keto diet is highly restrictive, and long-term compliance can be challenging. The sustainability of the diet is questionable, and there is a high likelihood of regaining weight after discontinuation.

Frequently asked questions
Yes, it is possible to reintroduce carbs into your diet after an initial period of significantly reducing your carb intake. However, this should be done in moderation and only on special occasions. It's important to return to the keto diet immediately afterward.
Yes, it is possible to build muscle while on a ketogenic diet, but it may not be as effective as a moderate-carb diet. Combining the keto diet with exercise and weight lifting can help minimize muscle loss.
Protein intake should be moderate as very high intake can spike insulin levels and lower ketones. Around 35% of total calorie intake is recommended as the upper limit for protein consumption.
You may not be in full ketosis or efficiently utilizing fats and ketones. To address this, try lowering your carb intake further and increasing your consumption of supplements like MCT oil or ketones.
