The ketogenic, or keto, diet is a low-carb, high-fat diet that has gained popularity for its potential benefits for weight loss and blood sugar control. While it may be an effective tool for weight loss, it's important to note that it is a highly restrictive diet that requires careful planning and monitoring. To keep calories low on a keto diet, it is crucial to focus on consuming healthy fats, moderate protein, and very few carbohydrates. This means filling up on foods like meat, fish, eggs, nuts, healthy oils, and low-carb vegetables, while strictly limiting sugary and starchy foods. In addition to weight loss, the keto diet has been associated with improved blood sugar control and reduced risk of heart disease. However, it is not without its risks, and it is always recommended to consult a healthcare professional before starting any new diet, especially one as restrictive as keto.

Eat more healthy fats
Eating more healthy fats is a key component of the keto diet. The keto diet is a low-carb, high-fat diet that can be effective for weight loss and certain health conditions. Here are some tips for eating more healthy fats on a keto diet:
- Include a variety of animal proteins such as fish, shellfish, meat, and poultry. These are low in carbs and rich in B vitamins and minerals. Salmon, sardines, and other fatty fish are also high in omega-3 fats, which have been linked to lower insulin levels and increased insulin sensitivity.
- Incorporate dairy products like cheese, plain Greek yogurt, and cottage cheese. These are high in fat and protein and can help decrease appetite and promote feelings of fullness.
- Use cream, half-and-half, and unsweetened plant-based milk as alternatives to dairy milk. These are very low in carbs and high in fat, making them ideal for keto.
- Avocados and olives are unique among vegetables as they are fairly high in healthy fats and low in net carbs. They also contain fiber and important antioxidants.
- Include healthy oils like olive oil, coconut oil, avocado oil, and ghee. These are pure fat sources with no carbs and can be used for cooking or as bases for salad dressings and healthy mayonnaise.
- Nuts and seeds are also healthy, high-fat, and low-carb options. They are linked to a reduced risk of heart disease, certain cancers, and depression.
- Dark chocolate with a minimum of 70% cocoa solids is a delicious source of antioxidants and can be enjoyed in moderation on a keto diet.

Consume fewer calories
While the keto diet is already low-carb, it is possible to consume fewer calories on keto. Here are some tips to keep your calorie count low while on a keto diet:
- Reduce your intake of carbohydrates: Carbohydrates are a significant source of calories, so by limiting your carb intake to 20-50 grams per day, you will naturally reduce your calorie intake. This can be challenging, so it is recommended to plan your meals ahead of time and choose keto-friendly options.
- Choose your protein sources wisely: While protein is an important part of the keto diet, eating too much can interfere with ketosis. It is recommended to eat enough protein to meet your needs, which is typically around 70 grams per day or 20-35% of calories.
- Focus on healthy fats: The keto diet is a high-fat diet, but not all fats are created equal. Prioritize healthy unsaturated fats found in foods like nuts, seeds, avocados, and olive oil. Limit your intake of saturated fats, which are linked to an increased risk of heart disease.
- Be mindful of portion sizes: Even though keto-friendly foods are generally high in fat and low in carbs, it is still possible to consume too many calories. Pay attention to portion sizes and avoid overeating, especially when it comes to high-calorie foods.
- Increase your physical activity: Creating a calorie deficit can be achieved not only by reducing calorie intake but also by expending more calories through exercise. Incorporating more physical activity into your lifestyle will help you burn more calories and create the calorie deficit needed for weight loss.
- Avoid processed foods: Processed foods, such as snack bars, keto desserts, and packaged foods, can derail your weight loss efforts as they are often high in calories. Stick to whole, unprocessed foods such as meat, fish, eggs, dairy, vegetables, and healthy fats.

Eat high-protein foods
Eating high-protein foods is essential when on a keto diet. The keto diet is a low-carb, high-fat diet that shares similarities with the Atkins and low-carb diets. It involves drastically reducing carbohydrate intake and replacing it with fat, which puts your body into a metabolic state called ketosis. In ketosis, your body uses fat for fuel instead of carbs, and it becomes incredibly efficient at burning fat for energy.
Animal Proteins
Fish and shellfish are keto-friendly and very low in carbs. Salmon, for example, is rich in B vitamins, potassium, and selenium. Meat and poultry are also staple foods on the keto diet as they contain no carbs and are rich in B vitamins and minerals. Eggs are another excellent source of protein, with each large egg containing less than 1 gram of carbs and about 6 grams of protein. Most animal proteins, including beef, pork, and seafood, are suitable for the keto diet.
Dairy and Dairy Alternatives
Cheese is a great option for keto as most varieties are very low in carbs and high in fat. Just 1 ounce of cheddar cheese provides 1 gram of carbs and 6 grams of protein. Other suitable dairy products include plain Greek yogurt, cottage cheese, cream, and half-and-half. Unsweetened plant-based milk, such as soy, almond, and coconut milk, are also keto-friendly.
Nuts and Seeds
Nuts and seeds are healthy, high in fat, and low in carbs. They are also high in fiber, which can help you feel full and naturally lower your calorie intake. Some of the best options for keto include almonds, walnuts, pumpkin seeds, and hemp seeds.
Tofu
Tofu is a soy-derived product that is high in protein and low in carbs, making it a good choice for plant-based diets. It can be added to both sweet and savory dishes to boost their protein content. Tofu is also a good source of calcium, selenium, zinc, and iron.
Chicken Breast
Chicken breast is a versatile and rich source of protein that contains zero carbohydrates. It is a staple in many low-carb diets and can be used to increase the protein content of dishes like salads, soups, and stir-fries.
