The ketogenic (keto) diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. To stay in ketosis, the general recommendation is to consume no more than 50 grams of net carbs per day, but this may vary depending on individual factors such as physical activity, stress levels, and sleep. The keto diet involves significantly reducing carbohydrate intake and replacing it with healthy fats and moderate amounts of protein. While it can be challenging to maintain due to its restrictive nature, the keto diet has been found to aid weight loss and improve blood sugar regulation, making it particularly beneficial for individuals with diabetes or other metabolic disorders.

The keto diet recommends a daily intake of 20-50 grams of carbs to reach ketosis
The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. The general recommendation for reaching and maintaining ketosis is to consume fewer than 50 grams of carbohydrates per day. However, some sources suggest that 20 grams of carbs per day may be more effective in promoting ketosis.
The keto diet involves drastically reducing carbohydrate intake and replacing those calories with fat. This shift in metabolism can have various health benefits, including weight loss, improved blood sugar regulation, and reduced insulin sensitivity for people with diabetes and metabolic disorders. To achieve these benefits, it is essential to limit carbohydrate intake to a maximum of 50 grams per day.
The number of carbohydrates one can consume and still remain in ketosis may vary between individuals. However, the recommended range of 20-50 grams of carbs per day is a good guideline for most people. This range is typically based on a 2,000-calorie-per-day diet and is flexible depending on individual factors. For example, those who engage in intense workouts may be able to consume more than 50 grams without exiting ketosis.
When counting carbs on the keto diet, it is important to focus on "net carbs." Net carbs refer to the carbohydrates that are absorbed into the body. Sources of carbohydrates like fiber and sugar alcohols are not absorbed into the bloodstream and, therefore, are not included in the daily allowance of net carbs. By focusing on net carbs, individuals can ensure they are getting enough essential fiber while still maintaining ketosis.
To calculate net carbs, one can use the following formula: Net Carbs = Total Carbs - Dietary Fiber - Half of Sugar Alcohols. This calculation will provide the number of net carbs that need to be kept below 50 grams per day on the keto diet.
It is worth noting that the keto diet can be challenging to maintain due to its restrictive nature. It is important to consult with a healthcare professional before starting the keto diet to ensure it is safe and suitable for your individual needs and goals. Additionally, regular health monitoring is recommended to check for any effects the diet may have on the body, such as the heart.

To calculate net carbs, subtract fibre and sugar alcohols from the total carb amount
To calculate net carbs, you need to subtract the amount of fibre and sugar alcohols from the total number of carbohydrates. This is because fibre and sugar alcohols are not absorbed into your bloodstream in the same way as other carbohydrates. Fibre is a type of carbohydrate that the body cannot digest, and sugar alcohols are only partially absorbed into the body and then excreted.
The calculation for net carbs is:
Net Carbs = Total Carbs – Fibre – Sugar Alcohols
For example, if a food contains 20g of total carbohydrates, 8g of fibre, and 5g of sugar alcohols, then the net carbs would be:
20g – 8g – 5g = 7g
It is important to note that this calculation may vary depending on the type of sugar alcohol. Erythritol, for instance, can be completely subtracted from the total carb count if it is the only sugar alcohol in the ingredients list.
Additionally, the calculation for net carbs may differ for those on a keto diet. The ketogenic diet typically restricts net carbohydrates to around 50g per day, and so those following this diet may also subtract half of the sugar alcohol content from the total carbohydrates to ensure they stay within this limit.
For example, if a food contains 23g of total carbohydrates, 9g of fibre, and 11g of sugar alcohols, then the net carbs would be:
23g – 9g – 5.5g (half of 11g) = 8.5g
This calculation ensures that those on the keto diet can still include fibre in their meals while staying within their desired carb limit.

Ketogenic diets promote nutritional ketosis, a metabolic state where the body uses fat for energy instead of sugars
The ketogenic diet promotes nutritional ketosis, a metabolic state where the body uses fat for energy instead of sugars. This is achieved by significantly reducing carbohydrate consumption and replacing those calories with fats.
To enter and remain in ketosis, an individual needs to consume less than 50 grams of carbohydrates each day. This is a stark contrast to the typical American diet, which includes 225-325 grams of carbohydrates daily.
The keto diet is an extremely low-carb, high-fat diet. It is a well-known way to reduce total calorie intake, balance blood sugar, and promote weight loss. The body can enter ketosis in a few different ways, including through starvation or fasting, when insulin levels drop and stored fat becomes the body's primary energy source.
The keto diet works by depriving the body of glucose, which is the convenient form of energy that comes from carbohydrates. When the body doesn't have enough glucose, it burns fat instead, turning it into a form of energy called ketone bodies. When the body is mostly running on ketones, it is in a state of ketosis.
Ketogenic diets promote nutritional ketosis by depriving the body of glucose while providing enough fat to keep ketone levels high without requiring starvation. This is done by establishing a daily carb limit, typically between 20 and 50 grams of net carbs per day, and fuelling up on healthy fats and protein.
While in ketosis, the body also produces less insulin and stores less fat. The keto diet has been found to have numerous health benefits, including weight loss, improved blood pressure, and better blood sugar regulation. It has also been explored as a potential treatment for epilepsy and certain cancers.
It is important to note that the keto diet drastically restricts many foods, so it is crucial to regularly assess your nutritional intake and ensure you are meeting your micronutrient needs. Additionally, it is always recommended to consult a healthcare professional before starting any new diet.

The keto diet is high in fat, with 70% of a person's intake coming from fat sources
The keto diet is a low-carb, high-fat diet that offers many health benefits. It involves drastically reducing your carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes incredibly efficient at burning fat for energy.
The standard ketogenic diet (SKD) is a very low-carb, moderate-protein, and high-fat diet. Typically, 70% of a person's intake comes from fat sources, 20% from protein, and only 10% from carbs. This means that 70-80% of your daily intake or calories should come from fat. For someone consuming 2,000 calories a day, this would be around 144-177 grams of fat.
On a keto diet, you will eat whole foods, including plenty of healthy fats, a moderate amount of protein, and low-carb vegetables. Foods such as eggs, healthy oils like coconut oil and olive oil, nuts, seeds, fatty fish, and full-fat dairy are all part of the keto diet.
The keto diet is different from other low-carb diets, like Atkins or the Mediterranean diet, as it is not a high-protein diet. It is extremely high in fats, and you need this fat to get enough calories to avoid any metabolic or thyroid problems associated with low-calorie intake.
It is important to note that the keto diet may not be suitable for everyone, and it is always best to consult your doctor before making any significant changes to your diet.

The keto diet restricts foods such as bread, beans, legumes, and some fruits and vegetables
The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. To stay in ketosis, a person should consume no more than 50 grams of net carbs per day, and ideally, the lower the better. Net carbs are the carbs absorbed into the body, excluding fibre and sugar alcohols.
Bread is typically high in carbs, with white bread containing more carbs than whole wheat bread. Other grain products like tortillas, pasta, cookies, crackers, and pizza crusts should also be avoided as they are made from grains and are high in carbohydrates.
Fruits that are high in sugar and carbs, such as dried fruits (raisins, dates, mango), fruit smoothies, and fruit juices (except lemon and lime juice), are also restricted on the keto diet. Low-glycemic fruits like berries, tomatoes, olives, and avocados are better options.
When it comes to vegetables, the keto diet recommends avoiding starchy vegetables that grow beneath the ground, such as potatoes, sweet potatoes, and other root vegetables. These vegetables have a high starch content and, therefore, a high number of carbs. Above-ground vegetables, like leafy greens and veggies that grow above the ground, are generally lower in carbs and are better options on the keto diet.
Legumes, including beans and peas, are typically high in protein and nutrients, but they are also high in carbs and should be avoided on the keto diet.
Dairy products are generally low in carbs, but some dairy items like creamed cottage cheese and fat-free or low-fat yogurt are best avoided as they contain more carbs.
In addition to these food restrictions, the keto diet also recommends limiting processed meats, unhealthy fats, and sugary drinks.
