What is the keto diet?

A healthy ketogenic diet should consist of 75 fat, 10-30 protein and no more than 5% or 20-50 grams of carbohydrates per day. Focus on high-fat, low-carbohydrate foods, such as eggs, meats, dairy and low-carbohydrate vegetables, as well as sugar-free beverages.

What is the keto diet?

A healthy ketogenic diet should consist of 75 fat, 10-30 protein and no more than 5% or 20-50 grams of carbohydrates per day. Focus on high-fat, low-carbohydrate foods, such as eggs, meats, dairy and low-carbohydrate vegetables, as well as sugar-free beverages. Be sure to restrict highly processed products and unhealthy fats. Studies have found that this very low-carb, high-fat diet is effective for weight loss, diabetes and epilepsy (1, 2).

However, higher quality research on the diet is still needed to determine its long-term safety and efficacy (1, 4,. A ketogenic diet usually limits carbohydrates to between 20 and 50 grams per day. Although this may seem challenging, many nutritious foods can easily fit into this way of eating. However, the carbohydrates in different types of seafood vary.

For example, while shrimp and most crabs do not contain carbohydrates, other types of seafood do (7,. Salmon, sardines, mackerel and other oily fish are high in omega-3 fats, which have been shown to reduce insulin levels and increase insulin sensitivity in overweight and obese people (1).In addition, frequent consumption of fish has been linked to decreased risk of disease and improved cognitive health (14, 1.The American Heart Association recommends consuming 1 to 2 seafood meals per week (1.Many types of seafood are carbohydrate-free or very low in carbohydrates. Fish and shellfish are also good sources of vitamins, minerals and omega-3s. The net carbohydrate content of non-starchy vegetables ranges from less than 1 gram for a cup of raw spinach to 7 grams for a cup of cooked Brussels sprouts (17, 1.Vegetables also contain antioxidants that help protect against free radicals, which are unstable molecules that can cause cell damage (19, 20).

In addition, cruciferous vegetables, such as kale, broccoli and cauliflower, have been linked to decreased risk of cancer and heart disease (21, 2). Net carbohydrates in non-starchy vegetables range from 1 to 8 grams per cup. Vegetables are nutritious, versatile and can help reduce the risk of disease. There are hundreds of types of cheese.

Fortunately, most are very low in carbohydrates and high in fat, making them well suited to a ketogenic diet. One ounce (28 grams) of cheddar cheese provides 1 gram of carbohydrates, 6.5 grams of protein and a good amount of calcium (2.Cheese also contains conjugated linoleic acid, which is a fat that has been linked to fat loss and improved body composition (2.In addition, eating cheese regularly may help reduce the loss of muscle mass and strength that occurs with aging. A 12-week study of older adults found that those who consumed 7 ounces (210 grams) of ricotta cheese per day experienced less loss of muscle mass and muscle strength over the course of the study than others (2.Here are some cheeses that are lower in carbohydrates for a keto diet. Cheese is rich in protein, calcium and beneficial fatty acids, but contains a minimal amount of carbohydrates.

Avocados are incredibly healthy; 3.5 ounces (100 grams), or about half of a medium avocado, contain 9 grams of carbohydrates. However, 7 of them are fibre, so their net carb count is only 2 grams (2.Avocados are high in several vitamins and minerals, including potassium, an important mineral that many people may not get enough of. What's more, higher potassium intake can ease the transition to a ketogenic diet (2.In addition, avocados can help improve cholesterol and triglyceride levels. One study found that participants who ate an avocado a day had beneficial effects on their cardio-metabolic risk factors, including lower levels of LDL (bad) cholesterol.

Avocados contain 2 grams of net carbohydrates per serving and are rich in fibre and several nutrients, such as potassium. In addition, they can help improve markers of heart health. Meat and poultry are considered staple foods in a ketogenic diet. Fresh meat and poultry contain no carbohydrates and are rich in B vitamins and several important minerals (31, 3.They are also a great source of high-quality protein, which has been shown to help preserve muscle mass during a very low-carbohydrate diet (33, 3).A study in older women found that eating a diet high in fatty meat led to HDL (good) cholesterol levels that were 5% higher than on a low-fat, high-carbohydrate diet (2.It is best to choose grass-fed meat, if possible.

This is because grass-fed animals produce meat with higher amounts of omega-3 fats, conjugated linoleic acid and antioxidants than meat from grain-fed animals (3.Meat and poultry contain no carbohydrates and are rich in high-quality protein and various nutrients. Grass-fed meat is the healthiest choice. Eggs are one of the healthiest and most versatile foods on the planet. One large egg contains less than 1 gram of carbohydrates and about 6 grams of protein, making eggs an ideal food for a ketogenic lifestyle (3.In addition, eggs have been shown to trigger hormones that increase feelings of fullness and satiety (37, 3.It is important to eat the whole egg, as most of the nutrients in an egg are found in the yolk.

This includes the antioxidants lutein and zeaxanthin, which help protect eye health (3.Although egg yolks are high in cholesterol, their consumption does not increase blood cholesterol levels in most people. In fact, eggs appear to modify the size of LDL particles in a way that reduces the risk of heart disease (40). Eggs contain less than 1 gram of carbohydrate each and can help keep you full for hours. They are also high in several nutrients and can help protect eye and heart health.

Plain Greek yoghurt and cottage cheese are healthy, protein-rich foods. Half a cup (105 grams) of plain Greek yoghurt provides 4 grams of carbohydrates and 9 grams of protein. That amount of cottage cheese provides 5 grams of carbohydrates and 11 grams of protein (41, 4.Both yogurt and cottage cheese have been shown to help decrease appetite and promote satiety (43, 4.Both plain Greek yogurt and cottage cheese contain 5 grams of carbohydrates per serving. Studies have shown that they help reduce appetite and promote satiety.

In addition, extra virgin olive oil is high in antioxidants known as phenols. These compounds further protect heart health by decreasing inflammation and improving artery function (47, 4). Frequent consumption of nuts has been linked to a reduced risk of heart disease, certain cancers, depression and other chronic diseases (49, 50). In addition, nuts and seeds are high in fibre, which can help you feel full and absorb fewer calories overall (5).

These small fruits are loaded with antioxidants that are credited with reducing inflammation and protecting against disease (63, 64, 6.Berries are rich in nutrients that may reduce the risk of disease. They provide 5-12 grams of net carbohydrate per 3.5-ounce serving. Butter and cream are good fats to include in a ketogenic diet. Each contains only minimal amounts of carbohydrate per serving (70, 7.In fact, some studies suggest that moderate consumption of high-fat dairy may reduce the risk of heart attack and stroke (74, 75, 7.Like other fatty dairy products, butter and cream are rich in conjugated linoleic acid, the fatty acid that can promote fat loss (30).

They contain less than 1 gram of net carbohydrate and 15 calories per serving because they are mainly water (7). The viscous fibre forms a gel that slows the movement of food through the digestive tract. This may help decrease hunger and blood sugar spikes, making it beneficial for weight loss and diabetes control (79, 80, 8.Shirataki noodles contain less than 1 gram of carbohydrate per serving. Its viscous fibre helps slow the movement of food through the digestive tract, which promotes satiety and stable blood sugar levels.

In addition, in vitro studies suggest that olive consumption may help prevent bone loss and reduce blood pressure, although human trials are not yet available (83, 8.Ten olives (34 grams) contain 2 grams of total carbohydrates and 1 gram of fibre. This translates to a net carbohydrate count of about 1 gram, depending on size (8.Olives are rich in antioxidants that may help protect heart and bone health. They contain 1 gram of net carbs per ounce. They contain caffeine, which increases metabolism and may help improve physical performance, alertness and mood (86, 87, 8.Dark chocolate contains flavanols, which may help reduce the risk of heart disease by lowering blood pressure and maintaining healthy arteries (91, 92, 9.Somewhat surprisingly, chocolate can be part of a ketogenic diet.

However, it is important to choose a dark chocolate containing a minimum of 70 ocoa solids, preferably more, and eat it in moderation. One ounce (28 grams) of unsweetened chocolate (100 ocoa) has 3 grams of net carbs (9.The ketogenic diet is a low-carb, high-fat diet. It lowers blood sugar and insulin levels and shifts the body's metabolism from carbohydrates to fats and ketones. In fact, research shows that the ketogenic diet can be as effective for weight loss as a low-fat diet (13, 14, 1).

A review of 13 studies found that following a very low-carbohydrate ketogenic diet was slightly more effective for long-term weight loss than a low-fat diet. People following the ketogenic diet lost an average of 2 pounds (0.9 kg) more than the group following a low-fat diet (1.At least initially, it is important to eat to satiety and avoid restricting calories too much. A ketogenic diet usually results in weight loss without intentional calorie restriction. The ketogenic diet is a high-fat, moderate-protein, low-carbohydrate diet.

The ketogenic diet is an eating plan consisting of 80 percent fat and little or no carbohydrates. The staples of the keto diet are fish, meat, eggs, dairy, oils and vegetables. Pasta, rice and other grains, potatoes and fruits are strictly forbidden. There is no "standard ketogenic diet with a specific ratio of macronutrients (carbohydrates, proteins and fats).

The ketogenic diet usually reduces total carbohydrate intake to less than 50 grams per day, less than the amount found in a normal medium bagel, and can be as low as 20 grams per day. In general, popular ketogenic resources suggest an average of 70-80at of total daily calories, 5-10 carbohydrates and 10-20 and protein. For a 2000 calorie diet, this translates to about 165 grams of fat, 40 grams of carbohydrates and 75 grams of protein. The amount of protein in the ketogenic diet is kept moderate compared to other low-carbohydrate, high-protein diets, because eating too much protein can prevent ketosis.

Amino acids from protein can be converted to glucose, so a ketogenic diet specifies enough protein to preserve lean body mass, including muscle, but will still cause ketosis. Aim for about 15 percent of calories to come from high-fat protein sources, such as those listed below. Some, such as Greek yoghurt, eggs and cheese, provide important vitamins to keep your hair, eyes and immune system strong. Experts also said that after 12 months on the diet, the weight loss advantage for keto followers compared to other dieters can plateau and disappear altogether.

Kirkpatrick, director of the Idaho State University Wellness Center, told The New York Times that keto should be considered a starter diet to be used before switching to a more sustainable carbohydrate intake. Fibre is present in plants and is important to include in a keto diet because fibre protects gut bacteria, improves digestive function and helps prevent constipation. The keto diet deliberately places the body in a state of ketosis, where fat is released from cells and converted into ketones, the body's plan B for energy production. In addition, because the ketogenic diet has not been studied long-term, researchers do not know whether the diet will cause nutrient deficiencies in people with or without diabetes.

Most people who follow a ketogenic diet follow the so-called standard ketogenic diet plan, which provides about 10 percent of their total calories from carbohydrates. If you are thinking about trying the ketogenic diet and you have diabetes, it is crucial that you consult your diabetes care team before doing so to make sure it is a safe and effective dietary approach for you. But the most important question of all is: how can you lose weight eating keto foods when you're eating bacon, butter and cheese? It's all about changing the way your body processes food depending on what you're giving it to work with. Eat too much or too little as part of your keto diet eating plan and you'll end up sabotaging your goals.

But there are plenty of keto diet foods that will make you feel full and satisfied, and maybe even like royalty. If losing weight fast while consuming almost unlimited amounts of fat sounds too good to be true, think again, say devotees of the keto diet. A buzzword that has hit the diet world seems to be "keto", referring to the high-fat, low-carb ketogenic diet. Many people follow a keto plan for a certain amount of time before altering the diet to include more carbohydrates and less fat.

Other low-carbohydrate diets may claim to be keto diets, but unless they include less than 50 grams of carbohydrate per day and only a moderate amount of protein, they may not reliably induce ketosis. According to Majumdar, the keto diet may pose a risk to people with various health problems, such as high blood pressure, heart disease, eating disorders, diabetes or kidney disease. A study published in the Journal of Nutrition and Metabolism notes that those following a "well-formulated keto diet typically consume less than 50 grams (g) of carbohydrate and approximately 1.5 g of protein per kilogram of body weight per day". A keto diet is low enough in carbohydrates and protein and high enough in fat to force the body to burn stored fat rather than consumed carbohydrates for energy.
