The ketogenic (keto) diet is a popular, low-carb diet that aims to put the body into a state of ketosis, where the body burns stored fat for fuel instead of carbohydrates. The number of carbs one can consume and remain in ketosis varies from person to person, but generally, it is recommended to limit carb intake to 15-50 grams per day. Eating more than 50 grams of carbs may disrupt ketosis, but this number is not a hard limit and can vary based on individual factors such as physical activity, stress levels, and sleep. For those new to the keto diet, it is recommended to start with an upper limit of 50 grams of carbs per day and gradually reduce this number to avoid unpleasant symptoms like the keto flu.

The keto diet limits carbs and replaces them with fats, putting the body into ketosis
The keto diet is a high-fat, low-carb eating plan that puts the body into a metabolic state called ketosis. Ketosis is when the body burns fat for energy instead of glucose. Normally, the body uses carbohydrates from food for energy, but when carb intake is very low, the body turns to burning fat instead. This process produces compounds called ketones, which become the body's main source of energy.
The keto diet typically consists of 70-80% fats, 10-20% proteins, and 5-10% carbohydrates. To enter and stay in ketosis, a person needs to limit their carb intake to up to 50 grams of carbohydrates per day. This can be challenging as it involves cutting out or significantly reducing many nutrient-rich foods such as whole grains, fruits, and vegetables. Bread, cereal, and other grains are restricted, and even fruit and vegetable intake must be carefully monitored.
Instead of carbohydrates, a person on the keto diet gets most of their calories from dietary fats. Healthy unsaturated fats are allowed, such as nuts, seeds, avocados, tofu, and olive oil. However, the keto diet also encourages the consumption of saturated fats, such as oils (palm and coconut), lard, butter, and cocoa butter.
The keto diet has become popular for weight loss and has also been used to help manage certain health conditions, including epilepsy, type 2 diabetes, and heart disease. However, it is not a balanced eating plan and can lead to nutrient deficiencies, especially if followed for an extended period. It is important to consult a doctor or dietitian before starting the keto diet, as it can be difficult to follow and may have side effects, including "keto flu," constipation, and high cholesterol.

To stay in ketosis, a person should consume up to 50 grams of carbs per day
The ketogenic (keto) diet is a popular but restrictive diet that involves limiting your carbohydrate intake and replacing those calories with fats. This diet puts your body into a state of ketosis, which is when your body breaks down ketone bodies (a type of fuel produced by the liver from fat) for energy instead of carbohydrates.
To stay in ketosis, a person should consume up to 50 grams of carbohydrates per day. However, the number of carbs you can consume and still remain in ketosis may vary from person to person. Some people may need to restrict their carb intake to as little as 20 grams per day to stay in ketosis, while others may be able to consume up to 60 grams without being kicked out.
The keto diet is very restrictive, as it excludes many foods that are high in carbohydrates, including some fruits and vegetables, bread, beans, and legumes. It is also important to consider the number of "net carbs" in foods, which is calculated by subtracting the amount of fibre and half the sugar alcohol content from the total number of carbs.
For those who are new to the keto diet, it is recommended to start with an upper limit of 50 grams of carbs per day and stick to it for several weeks instead of drastically cutting out carbs. This approach is more manageable and can help reduce the unpleasant symptoms of the "keto flu," which include fatigue, headache, brain fog, and upset stomach.
Additionally, it is important to note that the keto diet may not be suitable for everyone, especially those with diabetes. If you are considering starting the keto diet, it is recommended to consult with a doctor or dietician first to ensure it is safe for you.

The keto diet involves moderate amounts of protein as excess protein can prevent ketosis
The keto diet is a low-carb, high-fat diet that involves moderate amounts of protein. This is because excess protein can prevent ketosis, which is a metabolic state where the body burns fat for energy instead of glucose.
Ketosis is achieved by limiting carbohydrate intake to up to 50 grams per day. In this state, the body produces ketones, which are acids that appear in the blood and urine when the body burns fat. Ketosis can also lead to reduced insulin production and lower glucose levels.
While controlling carb intake is crucial for ketosis, monitoring protein intake is also essential. Protein is necessary for healthy brain function, skin, bone, and muscle health, building muscle mass, and recovering after workouts. However, when there are not enough carbohydrates in the body, it can turn to amino acids from proteins and convert them into glucose through a process called gluconeogenesis. This can interfere with ketosis.
To avoid this, keto dieters should aim for a moderate protein intake, typically between 10-20% of their daily calories. For a 2,000-calorie diet, this would be around 75 grams of protein. It's important to note that individual needs may vary based on age, gender, weight, and activity level.
In summary, while protein is an important part of the keto diet, excessive consumption can hinder ketosis. Therefore, it is crucial to monitor protein intake and aim for a moderate amount to support overall health and maintain the desired metabolic state.

The standard keto diet recommends 70% fat, 20% protein, and 10% carbs
The standard keto diet is the most researched and most recommended form of the keto diet. It is a very low-carb, moderate-protein, and high-fat diet that shares similarities with the Atkins and low-carb diets. The diet involves drastically reducing carb intake and replacing it with fat, which puts the body into a metabolic state called ketosis.
Ketosis is a metabolic state in which the body uses fat for fuel instead of carbs. This occurs when carb consumption is significantly reduced, limiting the body's supply of glucose (sugar), which is the main energy source for cells. Ketogenic diets can cause significant reductions in blood sugar and insulin levels, which has health benefits.
The keto diet recommends limiting carbs to 20 to 50 grams per day. This reduction in carbs causes a drop in blood sugar levels and a decrease in insulin release. As a result, the body turns to its secondary energy source, fats. When there are no other energy sources available, the body breaks down body fat for energy, which is known as ketosis.
To stay in ketosis, a person needs to consume up to 50 grams of carbs per day. This may vary slightly between individuals, but generally, staying under 50 grams of carbs per day is necessary to reach ketosis. This limit leaves you with limited carb options, mainly vegetables and small amounts of berries.
The standard keto diet is a challenging diet to follow due to its restrictiveness. It requires careful planning and monitoring of macronutrient intake. It is important to consult a healthcare provider before starting the keto diet or any new diet to ensure it is safe and suitable for your individual needs and goals.

Ketosis takes about 72 hours to kick in
Ketosis is a metabolic state in which the body uses fat as its main fuel source or energy. Typically, the body uses blood sugar (glucose) as its key energy source. Glucose is derived from eating carbohydrates. When the body doesn't have enough glucose, it burns fat instead. This process of burning fat for energy is called ketosis.
To enter ketosis, you need to restrict your carbohydrate intake to under 50 grams per day. The time it takes to enter ketosis varies from person to person. However, it generally takes 72 hours, or two to four days, to kick in.
Factors that may influence how long it takes to enter ketosis include:
- Carbohydrate, fat, and protein intake
- Physical activity level
- Age
- Metabolism
People who consume a high-carb diet before starting a keto diet may take longer to enter ketosis than those who generally eat a low to moderate amount of carbs. This is because the body needs to deplete its glycogen stores before entering ketosis.
You can encourage your body to enter ketosis by:
- Increasing your physical activity
- Fasting for short periods
- Increasing your intake of healthy fats
- Testing your ketone levels
- Checking your protein intake
- Consuming more MCT oil
