When people hear the word “diet,” they think of counting calories.But with a ketogenic diet (or keto, as it is also called), you will not have to waste time on this activity.Keto is a special high-fat, low-carb diet that puts the body into a state of ketosis, meaning it uses stored fat stores for energy.
During keto (i.e. 2-3 weeks), you can only consume 20-50 g of carbohydrates per day, but the body should receive 60 to 80% of all calories from fat.Studies have shown this low-carb diet to be effective for weight loss, type 2 diabetes, polycystic ovary syndrome (PCOS), acne, and epilepsy.It is also useful for some forms of cancer and Alzheimer's.
Pros and cons of the ketogenic diet
The main advantage of the ketogenic diet is that it really helps to lose weight, reduces the level of bad cholesterol and increases the amount of healthy cholesterol.As the body uses its fat reserves for energy, appetite often decreases (this process may have been built into humans during evolution to help them survive times of famine).Furthermore, fats are digested much more slowly than carbohydrates and prolong the feeling of satiety between meals.
But, like any other diet, keto has its drawbacks.You may later notice side effects: bad breath, headache, nausea and fatigue.Symptoms that occur in the first few days of keto often resemble the condition at the onset of the disease.The loss of energy and the feeling of tiredness appear due to a sharp decrease in blood sugar levels, but after 24-48 hours there is no trace of it anymore.
During keto, you may experience bloating or constipation, and urination may also increase during ketosis.Because following a ketogenic diet requires you to eat only certain food groups, you run the risk of developing nutritional deficiencies that can make your hair and nails brittle.
Many patients believe that after completing a course of dietary nutrition, they will easily regain the lost kilograms.This can be avoided by avoiding carbohydrates and trying to eat low-carb foods.
What foods can you eat on keto?
The ketogenic diet helps you lose weight, control your blood sugar level and solve health problems.As you already understood, choosing it you will have to eat exclusively fatty foods.But no, we're not talking about battered burgers and onion rings – you're just looking for healthy fats!Where can I find them?You won't believe it, but on keto you can eat tasty, satisfying and varied, while the low-carb foods that you will eat for the next 2-3 weeks (as a rule, ketosis begins on the 7th day of the diet) are easy to find in supermarkets.To get the most benefits and reduce the side effects of dietary restrictions, eat the following 15 foods regularly.
Fish and seafood
Perhaps fish and seafood are the best sources of vitamins, minerals and omega-3s.At the same time, in many seafood the amount of carbohydrates is negligible or even absent (for example, in shrimp).If we talk about the most popular products, 100 g of mussels contain 5 g of carbohydrates, octopus and oysters - 4 g each, squid - 3 g.By the way, frequent consumption of fish reduces the risk of developing various diseases and improves mental health, so try to eat it at least twice a week.
Low carb vegetables
Vegetables are nutritious and versatile foods, the important thing is to choose those that do not contain starch.On average, a serving of non-starchy vegetables contains 1 to 8 grams of carbohydrates.Therefore, you can safely include zucchini, cabbage, celery and cherry tomatoes in your diet.
Cheese
There are hundreds of types of cheese, and fortunately, they are all low carb and high in fat, making them very suitable for a ketogenic diet.Cheeses are rich in protein, calcium and healthy fatty acids.Additionally, eating cheese regularly can help reduce muscle loss experienced by older adults.
Avocado
A serving of avocado contains 2 grams of net carbohydrates, lots of fiber and a variety of nutrients, including potassium.Additionally, avocado helps support heart function, lowers cholesterol levels, and influences triglycerides in the body.By mixing it with spices you can obtain an excellent seasoning for vegetable and fish dishes.
Meat and poultry
Meat and poultry are considered staple foods on a ketogenic diet.They contain no carbohydrates and are rich in vitamins such as vitamin B and minerals including potassium, selenium and zinc.Meat and poultry are also an excellent source of high-quality protein, which numerous studies show helps maintain muscle mass during a low-carb diet.
Egg
Eggs are one of the healthiest and most versatile foods on our planet.One large egg contains less than 1 gram of carbohydrates and about 6 grams of protein, making eggs an ideal food for people on keto.Furthermore, egg consumption affects the production of hormones that prolong the feeling of satiety and maintain blood sugar levels, resulting in a significant reduction in the total calorie content of food consumed in a day.
By the way, it's important to note that you need to eat the whole egg, not just the egg white: The yolk contains the most nutrients, including the antioxidants lutein and zeaxanthin, which help maintain eye health.
Coconut oil
Coconut oil contains medium chain triglycerides (MCTs).Unlike long-chain fats, MCTs are absorbed directly by the liver, subsequently transforming into ketones or becoming a source for quickly obtaining the necessary energy.
Furthermore, coconut oil increases the metabolic rate, promotes weight loss and eliminates abdominal fat deposits.It is important that it is of high quality: cheap products contain a lot of fragrances and additives.
Plain Greek yogurt and cream cheese
Regular Greek yogurt and cottage cheese are healthy, protein-rich foods.And although they contain some carbohydrates, they can still be included in the ketogenic diet.150g of plain Greek yogurt contains 5g of carbohydrates and 11g of protein.The same amount of cottage cheese provides 5 g of carbohydrates and 18 g of protein.By the way, studies have shown that yogurt and cottage cheese help reduce appetite and promote a quick feeling of satiety.
Olive oil
Olive oil is rich in oleic acid, a monounsaturated fat that reduces risk factors for heart disease, as well as rich in antioxidants known as phenols.These compounds also protect the heart, reduce inflammation in the body, and improve arterial function.Olive oil is ideal for salad dressings, mayonnaise and added to cooked foods.
Nuts and seeds
Frequent consumption of nuts reduces the risk of heart disease, some types of cancer, depression and other chronic diseases.Additionally, nuts and seeds contain a large amount of fiber.But the amount of carbohydrates in them varies.The minimum amount is in pecans and Brazil nuts - only 1 g per serving (30 g), in walnuts and macadamia nuts - 2 g, in almonds and sesame seeds - 3 g, in pumpkin seeds - 4 g, in pistachios - 5 g and in cashews - 8.
Berries
Most fruits are too high in carbohydrates, so you will have to avoid them during the ketogenic diet.Another thing is berries.They are rich in nutrients that can reduce the risk of developing a wide variety of diseases.A 100g serving of berries provides 5-12g of net carbs.For example, in blackberries there is only 5 g, in blueberries - 12 g, in raspberries and strawberries - 6 g each.
Butter and cream
Butter and cream are low-carb foods.Research has shown that, contrary to popular belief, they have neutral or beneficial effects on the heart when consumed in moderation.
Olives
One serving of olives (about 28 g) contains 2 g of carbohydrates, including 1 g of fiber.They are rich in oleuropein, an antioxidant that protects the heart.Eating olives helps prevent bone loss and lower blood pressure.
Unsweetened coffee and tea
Unsweetened coffee and tea do not contain carbohydrates.Thanks to caffeine, they can speed up the metabolism, improve physical performance, alertness and mood.They can also reduce the risk of developing diabetes.Avoid coffee from the "3 in 1" series and tea bags: as a rule, manufacturers add powdered milk and high-carbohydrate flavors.
Dark chocolate and cocoa powder
Yes, the ketogenic diet allows you to eat dark chocolate (at least 70%) and accompany it with cocoa.This is because these foods are excellent sources of antioxidants.Cocoa contains about the same amount as blueberries and acai berries.But dark chocolate contains flavanols, biologically active substances that reduce the risk of heart disease.30g of unsweetened chocolate contains only 3g of net carbohydrates, while chocolate with sugar contains 10g.
