The ketogenic diet is a high-fat, moderate-protein, and very low-carb eating plan. The number of carbs a person can consume and stay in ketosis varies, but it's generally agreed that up to 50 grams of carbs per day is the limit to stay in ketosis. The exact number of grams of carbohydrates will differ for everyone, but it is usually around 20 to 50 grams per day. Many people on a keto diet count net carbs, which is total carbs minus fibre. Fibre isn't counted in the carbohydrate total because it isn't digested by the human body.

The keto diet is a high-fat, moderate-protein, very low-carb eating plan
The exact ratio of fat, protein, and carbohydrates can vary, but a typical keto diet consists of about 70% fat, 20-25% protein, and 5-10% carbohydrates. In terms of grams, this usually translates to around 20-50 grams of carbohydrates per day, although some sources recommend staying under 20 grams of net carbs. Net carbs are calculated by subtracting the grams of fibre and certain sugar alcohols from the total number of carbs.
The keto diet has become popular as a weight loss strategy, but it was originally used as a therapeutic diet to control seizures in people with epilepsy. It has also been used to help manage type 2 diabetes and may have benefits for certain other medical conditions.
While the keto diet can be effective for weight loss, it is very restrictive and may be challenging to maintain. It also carries the risk of negative side effects, such as constipation, headaches, and nutrient deficiencies. Therefore, it is important to consult with a healthcare professional before starting the keto diet and ensure you are consuming a variety of recommended foods to minimise the risk of nutrient deficiencies.

To stay in ketosis, a person requires up to 50 grams of carbs per day
The ketogenic (keto) diet is a low-carbohydrate, high-fat eating plan that has been used to treat specific medical conditions, such as epilepsy and diabetes. The diet has gained popularity as a potential weight-loss strategy, with many people using it to lose weight. The keto diet typically restricts total carbohydrate intake to less than 50 grams per day, and can be as low as 20 grams per day. This restriction is important because it forces the body to burn fat instead of carbohydrates for energy, which leads to a state called ketosis.
When following the keto diet, it is important to consider the number of "net carbs" in foods. Net carbs are calculated by subtracting the amount of fibre and certain sugar alcohols from the total number of carbs. Fibre is a type of carbohydrate that the body cannot digest, so it is not included in the number of net carbs. Sugar alcohols, such as erythritol, are only partially digested and can affect blood sugar levels, so they are also subtracted from the total carb count.
The standard keto diet consists of 70% fat, 20% protein, and 10% carbs. However, there are different variations of the keto diet, such as the cyclical ketogenic diet and the targeted ketogenic diet, which allow for more carbs on certain days or around high-intensity workouts.
Keeping to the keto diet can be challenging due to its restrictive nature. It is important to carefully plan meals and read food labels to ensure that carb intake stays within the recommended range. Some foods that are high in carbs and should be avoided or limited on the keto diet include fruits, starchy vegetables, bread, beans, legumes, and wheat-based products like rice, pasta, and cereals.
In conclusion, to stay in ketosis, a person should limit their carb intake to up to 50 grams per day. This may vary slightly depending on the individual, but generally, consuming 50 grams or less of carbs per day will keep the body in ketosis. The keto diet is a very low-carb, high-fat diet that has gained popularity for weight loss and other potential health benefits.

The keto diet originated as a therapeutic diet used to control seizures in people with epilepsy
The keto diet is more than just a trendy weight-loss tactic. It originated as a therapeutic diet used to control seizures in people with epilepsy. The "classic" ketogenic diet is a special high-fat, low-carbohydrate diet that has been used since the 1920s to treat epilepsy. It is usually used in children with seizures that do not respond to medications. The diet is stricter than the modified Atkins diet, requiring careful measurements of calories, fluids, and proteins. The name ketogenic means that it produces ketones in the body. Ketones are formed when the body uses fat for its source of energy instead of carbohydrates.
The ketogenic diet is not recommended as a primary anti-seizure option because patients are often averse to drastic changes in their food intake or have trouble staying on the diet due to its strict requirements and potential side effects like nausea, constipation, and fatigue. However, it has been shown to be effective in reducing seizures in many children whose seizures could not be controlled by medications. Over half of the children who go on the diet have at least a 50% reduction in the number of their seizures.
A keto diet generally consists of 70 to 75 percent fat, 20 to 25 percent protein, and 5 to 10 percent carbohydrates. The exact number of grams of carbohydrates will be different for everyone, but it is generally around 20 to 50 grams per day. Many people on a keto diet count "net carbs," which is the total number of carbohydrates minus the fiber. Fiber isn't counted in the total carbohydrates because it isn't digested by the human body. Eating a little fruit, starchy vegetables, sugary foods, or whole grains can easily kick you out of ketosis.
There are different forms of the ketogenic diet, including the classical ketogenic diet, the medium-chain triglyceride (MCT) ketogenic diet, the modified Atkins diet, the modified ketogenic diet, and the low glycaemic index treatment (LGIT). The classical ketogenic diet includes very little carbohydrate and protein, with each meal including a strictly measured ratio of fat to carbohydrates and protein. The MCT ketogenic diet includes more carbohydrates and allows for some fat from naturally fatty foods and some fat from a supplement of MCT oil or emulsion. The modified Atkins diet and modified ketogenic diet are more flexible and allow for more protein and approximate portion sizes. The LGIT focuses on how carbohydrates affect blood glucose levels and also uses approximate portion sizes.
The ketogenic diet can be adapted to diets from all different cultures, as well as for people with allergies or those on modified texture diets. It is important to consult with a trained medical specialist and dietitian before starting the ketogenic diet to ensure it is done safely and effectively.

Ketosis is when your body has switched into a fat-burning state and breaks down fat into ketone bodies that are used as energy
Ketosis is the goal of a ketogenic (keto) diet. The keto diet is a high-fat, very low-carb eating plan. The body achieves ketosis by drastically restricting carb intake, so that it begins producing ketones from stored and consumed fats, which it then uses for energy. The keto diet typically comprises 70-80% fat, 10-20% protein, and 5-10% carbs. This equates to around 20-50 grams of carbs per day.
The keto diet was originally used therapeutically to control seizures in people with epilepsy. Today, it is often used for weight loss, and has been shown to produce beneficial metabolic changes in the short term, including lower insulin resistance, blood pressure, and cholesterol.
However, there are some negative side effects and risks associated with the keto diet. It can be challenging to maintain, and may cause hunger, fatigue, low mood, irritability, constipation, headaches, and brain fog. Long-term, it may increase the risk of kidney stones, osteoporosis, and gout. It also tends to be very restrictive, banning most fruits, starchy vegetables, legumes, grains, and more.

Net carbs = Total Carbohydrates - fibre - sugar alcohols
The keto diet is a low-carb, high-fat eating plan that has been used to treat specific medical conditions. The diet aims to limit carbohydrate intake so that the body enters a state of ketosis, where it burns fat for energy instead of carbohydrates. To stay in ketosis, a person can consume up to 50 grams of carbs per day. However, different keto diets allow for different amounts of carbs, protein, and fat. The standard ketogenic diet consists of 70% fat, 20% protein, and 10% carbs.
When following the keto diet, it is important to consider the number of "net carbs" in foods. Net carbs are calculated by subtracting the amount of fibre and certain sugar alcohols from the total number of carbs. The formula for calculating net carbs is:
For example, 1 cup of cauliflower rice contains 4.8 grams of total carbs and 3.2 grams of fibre. To calculate the net carbs, you subtract the fibre (3.2 grams) from the total carbs (4.8 grams), resulting in 1.6 grams of net carbs.
It is recommended to only subtract the fibre that naturally occurs in whole foods, as your body may respond differently to added fibre in processed keto products. Additionally, when calculating net carbs, it is important to consider the type of sugar alcohol. Erythritol, for example, has a minimal impact on blood glucose and ketone levels, while maltitol can affect blood glucose and insulin levels.
By counting net carbs instead of total carbs, individuals can include more vegetables and other nutritious foods in their diet while still maintaining ketosis. Net carbs allow for greater flexibility and a wider variety of food choices on the keto diet.

Frequently asked questions
The ideal carb intake for a keto diet is generally considered to be less than 50 grams per day. However, the exact amount may vary depending on individual factors such as activity level, weight, and metabolism.
Net carbs refer to the amount of carbs in a food item after subtracting the fibre content. To calculate net carbs, subtract the grams of fibre from the total number of carbs. For processed foods, also subtract half of the sugar alcohol content.
On a keto diet, it is recommended to consume high-fat, low-carb foods such as meat, fish, cheese, dark green vegetables, avocados, berries, and nuts. Foods to avoid include starchy foods like bread, pasta, rice, potatoes, and high-sugar fruits.
A keto diet may aid in weight loss and improve health parameters such as insulin resistance, high blood pressure, and elevated cholesterol. However, it may also lead to unpleasant side effects like constipation and headaches, and there is a risk of nutritional deficiencies if not carefully planned. Long-term studies are needed to fully understand the potential risks and benefits.
