The ketogenic diet, or keto, is a low-carbohydrate, high-fat eating plan that has been used for centuries to treat specific medical conditions. The keto diet typically reduces total carbohydrate intake to less than 50 grams a day, with some versions of the diet allowing for up to 100 grams of carbs per day. The standard keto diet consists of 70% fat, 20% protein, and 10% carbs. The high-fat content of the keto diet is meant to induce a state of ketosis in the body, where it burns fat for fuel instead of carbohydrates. This can lead to weight loss and improved blood sugar control, making it a popular diet for people looking to lose weight or manage their blood sugar levels. However, the keto diet may not be suitable for everyone, including pregnant women, serious endurance athletes, and people with certain medical conditions.

Keto requires limiting your daily carb intake to 20-50g
The keto diet is a low-carb, high-fat diet that can be an effective tool for weight loss and certain health conditions. To achieve ketosis, a metabolic state where your body burns fat for fuel, you need to significantly reduce your carbohydrate intake.
On a keto diet, your daily carb intake should be limited to 20-50 grams. This restriction is crucial for reaching and maintaining ketosis. The fewer carbs you consume, the more effective the diet is for weight loss and managing health conditions like type 2 diabetes.
To ensure you stay within the recommended carb range, it's important to track your carb intake, especially in the beginning. You can calculate your net carbs by subtracting fibre and sugar alcohols from the total carbohydrate amount. However, this calculation is not an exact science, and the effect of sugar alcohols on absorption and blood sugar can vary.
Sticking to the allowed carb range can be challenging, as many nutritious foods like fruits, whole grains, and some vegetables are high in carbs. It's important to carefully plan your meals and choose low-carb options like non-starchy vegetables, nuts, and seeds.
While limiting carbs is essential, a keto diet also requires adequate protein intake and adding healthy fats for flavour and satiety. It's recommended to get at least 70 grams of protein per day, or 20-35% of your calories from protein. As for fats, aim for about 60-75% of your calories from fat sources like olive oil, nuts, and avocado.
Remember that keto is not suitable for everyone. It's important to consult with a healthcare professional before starting a keto diet, especially if you have any health conditions or are taking medications.

The diet is high in fat, with 60-80% of calories from fat
The keto diet is a high-fat, low-carb, and moderate-protein diet. It involves getting 60-80% of your calories from fat, 10-20% from protein, and just 5-10% from carbohydrates. This means that, on a 2,000-calorie diet, you'd be consuming about 165 grams of fat, 40 grams of carbohydrates, and 75 grams of protein.
On the keto diet, you cut back significantly on carbs so that your body enters a state called ketosis, where it burns fat for fuel instead of carbs. This shift from burning carbs to burning fat can lead to weight loss and increased energy.
To achieve ketosis, it's important to consume plenty of healthy fats. This includes natural fats like butter and olive oil, as well as fatty cuts of meat, nuts, seeds, and fatty fish. The focus on fat means that you will likely be consuming more calories from fat than you're used to. However, this doesn't mean that you should go overboard with fat—only consume enough to feel satisfied.
In addition to fat, make sure to include a moderate amount of protein in your diet. This includes foods like meat, fish, poultry, and eggs. Too much protein, however, can prevent ketosis, as excess protein can be converted to glucose.
While the keto diet is high in fat, it's important to choose healthy fats like monounsaturated and omega-3 fats. Avoid trans fats, and limit your consumption of saturated fats, as these can have adverse effects on your cholesterol levels.
Overall, the key to the keto diet is drastically reducing your carb intake and increasing your fat intake so that your body enters ketosis and starts burning fat for fuel. This shift can lead to weight loss and increased energy, but it's important to ensure you're getting enough nutrients and not overdoing it with unhealthy fats.

It's also high in protein, with 10-35% of calories from protein
The keto diet is a low-carb, high-fat diet that can be effective for weight loss and certain health conditions. On a keto diet, you cut back significantly on carbohydrates, in order to burn fat for fuel. This puts your body into a metabolic state called ketosis.
The keto diet is typically comprised of 70-80% fat, 10-20% protein, and 5-10% carbohydrates. However, there are different types of keto diets, such as the standard ketogenic diet (70% fat, 20% protein, and 10% carbs), the cyclical ketogenic diet (5 low-carb days and 2 high-carb days), the targeted ketogenic diet (more carbs around high-intensity workouts), and the high-protein ketogenic diet (60% fat, 35% protein, and 5% carbs).
Protein is an important component of the keto diet, as it can improve feelings of fullness and increase fat burning. However, it is important not to consume too much protein, as this can prevent your body from reaching ketosis. The recommended range for protein intake on the keto diet is 0.7-0.9 grams of protein per pound of body weight, or 10-35% of calories from protein.
When following a keto diet, it is important to eat a moderate amount of protein and include enough fat to add flavor and feel satisfied. The focus should be on eating whole, unprocessed foods to benefit from their vitamins and minerals.
Some examples of high-protein foods that are suitable for the keto diet include red meat, poultry, fish, eggs, tofu, nuts, and seeds. By including a variety of these protein sources in your diet, you can ensure that you are getting enough protein while still maintaining ketosis.

Meat, fish, eggs, cheese, nuts, and non-starchy vegetables are all great foods to eat when on the keto diet.
The keto diet is a low-carb, high-fat diet that can be effective for weight loss and certain health conditions. It involves limiting your carbohydrate intake to a maximum of 50 grams per day, or 20 grams if you want to be extra strict, and getting the rest of your calories from fat and protein.
Meat and fish are great sources of protein on the keto diet. You can eat all types of meat, including red meat, such as beef, pork, and lamb, and poultry, such as chicken and turkey. Fatty fish, such as salmon, tuna, and trout, are also excellent choices as they provide both protein and healthy fats.
Eggs are another excellent source of protein and can be enjoyed in various ways on the keto diet. Cheese is also allowed on the keto diet and is a good source of fat and protein. Just be mindful of the type of cheese you choose, as some varieties are high in lactose sugar and should be limited.
Nuts are a great snack option on the keto diet. They provide healthy fats, protein, and fiber, which can help keep you feeling full and satisfied. Just be mindful of your portions, as nuts can be high in calories.
When it comes to vegetables, it's important to choose non-starchy options on the keto diet. Leafy greens, such as spinach and kale, and non-starchy vegetables, such as broccoli, cauliflower, zucchini, and asparagus, are all excellent choices. These vegetables are low in carbs and provide important nutrients like fiber, vitamins, and minerals.
By focusing on these food groups, you can create delicious and nutritious meals that fit within the keto diet guidelines. Just remember to track your carbohydrate intake and make sure you're staying within the recommended range to maintain ketosis.

It's not suitable for everyone, e.g. pregnant women and people with type 1 diabetes
The keto diet is not suitable for everyone, and it is always best to consult a doctor or nutritionist before making any significant changes to your diet. Here are some reasons why the keto diet may not be suitable for certain individuals:
Pregnant Women:
- Nutritional deficiencies: The keto diet restricts carbohydrates, including fruits and most vegetables, which are essential sources of vitamins, iron, and folate for pregnant women. These nutrients are vital for the growth and development of the baby. Vegetables also provide fiber, which can help with pregnancy constipation.
- Saturated fat: The keto diet encourages a high intake of fat, which can include unhealthy meats, oils, butter, and lard. Excessive saturated fat consumption can lead to higher cholesterol levels, putting strain on the heart and pregnancy.
- Side effects: The keto diet may cause side effects like nausea, vomiting, tiredness, and aches, which can be uncomfortable for pregnant women who are already experiencing similar symptoms.
- Research on animals: Most research on the keto diet during pregnancy has been conducted on animals, showing potential risks to embryonic growth and brain development. However, the effects on humans are not yet fully understood.
People with Type 1 Diabetes:
- Dyslipidemia: The keto diet may lead to an increased risk of dyslipidemia, which is a condition characterized by abnormal levels of lipids (fats) in the blood. This can be a concern for people with type 1 diabetes.
- Diabetic ketoacidosis: There is a risk of developing diabetic ketoacidosis, a dangerous complication of diabetes where the body produces high levels of ketones, leading to a build-up of acids in the blood.
- Hypoglycemia: The keto diet may increase the risk of hypoglycemia, or low blood sugar, which can be dangerous for people with type 1 diabetes.
- Insulin therapy adjustments: People with type 1 diabetes who follow a keto diet may need to closely monitor and adjust their insulin therapy. This includes reducing basal insulin and bolus insulin doses to prevent hypoglycemia.
- Medication interactions: Certain medications for type 1 diabetes, such as SGLT-2 inhibitors, may need to be discontinued when following a keto diet due to the risk of euglycemic diabetic ketoacidosis. Other medications, like GLP-1 receptor agonists, may increase the risk of hypoglycemia and ketoacidosis.
