The ketogenic or keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. To stay in ketosis, a person can consume up to 50 grams of carbs per day, though some sources suggest that 20 grams is the upper limit. This involves replacing high-carb foods with fatty foods such as eggs, dairy products, meat, and fish. The keto diet is gaining popularity as a potential weight-loss strategy, but it is not suitable for everyone.

To enter ketosis, you need to consume under 50g of carbs per day
Ketosis is a metabolic state where the body burns fat for energy instead of carbohydrates, its preferred source. The body can enter ketosis when there is a lack of glucose, its primary energy source. This occurs when you deprive the body of glucose by reducing your carbohydrate intake to a minimum.
The keto diet recommends a daily intake of 20-50g of carbohydrates, with some suggesting that an intake of 50g or less is optimal for ketosis. This is a very restrictive diet, as it means you can only eat certain vegetables, berries, and other low-carb foods.
To calculate your net carb intake, you can subtract the amount of fibre and half the amount of sugar alcohols from the total amount of carbohydrates. This will give you the number of net carbs, which is the amount your body actually absorbs.
It's important to note that ketosis can be dangerous for some people, especially those with type 1 or type 2 diabetes, and anyone considering the keto diet should consult their doctor first.

Net carbs are absorbed into the body, while total carbs aren't
The keto diet is a low-carb, high-fat eating plan that has been used to treat specific medical conditions and promote weight loss. To stay in ketosis, a person can consume up to 50 grams of carbs per day. However, not all carbs are equal when it comes to the keto diet.
"Net carbs" refer to the amount of carbohydrates that are absorbed and utilised by the body for energy. Net carbs are calculated by subtracting indigestible carbohydrates like fibre and sugar alcohols from the total carbohydrate amount. These indigestible carbs are not absorbed into the bloodstream and, therefore, do not count towards your daily allowance of net carbs.
On the other hand, "total carbs" refer to all the carbohydrates in a serving of food, including those that the body cannot digest and turn into glucose for energy. Fibre, for example, is a type of carbohydrate that the body cannot digest and, thus, is not included in the number of net carbs.
When following the keto diet, it is crucial to focus on net carbs rather than total carbs. This distinction ensures that you do not deny your body the essential fibre it needs for proper function while still keeping track of the carbs that impact your ketosis state. By subtracting the fibre content and half the sugar alcohol content from the total carbs, you can calculate the net carbs in a serving and make informed food choices to stay within your daily limit.

You can calculate net carbs by subtracting fibre and sugar alcohols from total carbs
The keto diet is a low-carb, high-fat eating plan that has been used to treat specific medical conditions such as epilepsy and diabetes. It has gained popularity as a potential weight-loss strategy. The diet typically restricts total carbohydrate intake to less than 50 grams per day, with some people aiming for 20 grams or fewer.
To stay in ketosis, a person needs to consume no more than 50 grams of net carbs per day. Net carbs refer to the amount of carbohydrate that is absorbed into the body and contributes to calories. Net carbs can be calculated by subtracting indigestible carbohydrates (fibre and sugar alcohols) from the total amount of carbohydrates.
For example, let's say a food has 20 grams of total carbohydrates, 8 grams of fibre, and 5 grams of sugar alcohols. To calculate the net carbs, you would subtract the amount of fibre and half the amount of sugar alcohols from the total carbohydrates:
20 grams total carbs - 8 grams fibre - 2.5 grams sugar alcohols = 9.5 grams net carbs
This calculation can be done using the nutritional information on food labels. It's important to note that the calculation of net carbs is not an exact science, as the effect of sugar alcohols on absorption and blood sugar can vary.
By focusing on net carbs, individuals can ensure they are not denying their bodies essential fibre while still maintaining ketosis.

Non-starchy vegetables are a good source of fibre and vitamins
Non-starchy vegetables are an important part of the keto diet. They are a good source of fibre and vitamins, which are essential for maintaining a healthy body and preventing constipation, a common side effect of the keto diet.
The keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. It has gained popularity in recent years as a potential weight-loss strategy. To follow the keto diet, one must limit their carbohydrate intake to up to 50 grams per day and replace those carbs with fats. This puts the body into a state of ketosis, where it burns fat for energy instead of carbohydrates.
Non-starchy vegetables are a great way to include valuable vitamins and minerals in the keto diet while staying within the strict carbohydrate limit. Examples of non-starchy vegetables that are allowed on the keto diet include leafy greens such as kale, Swiss chard, collards, spinach, bok choy, and lettuces, as well as broccoli, cauliflower, asparagus, bell peppers, onions, and mushrooms. These vegetables are low in net carbs, which is the amount of carbohydrates that are absorbed by the body and contribute to calories.
It is important to note that not all vegetables are allowed on the keto diet. Starchy vegetables like potatoes, corn, and winter squash are off-limits due to their high carbohydrate content.
By including a variety of non-starchy vegetables in their meals, those following the keto diet can ensure they are getting enough fibre and essential vitamins while still maintaining the strict carbohydrate limit.

The keto diet is not suitable for everyone
The keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. In recent years, it has gained popularity as a potential weight-loss strategy. However, the keto diet is not suitable for everyone. Here are some reasons why:
Potential Health Risks
The keto diet can lead to an increased risk of kidney stones, osteoporosis, and higher blood levels of uric acid, which is a risk factor for gout. It can also cause nutrient deficiencies, especially if a variety of recommended foods are not included. The high-fat content of the keto diet, which is typically around 70% to 80% of total calories, can be challenging for some people to adjust to and may lead to negative side effects.
Restrictive Nature
The keto diet is very restrictive, excluding several food groups such as grains, fruits, starchy vegetables, legumes, and sugar. This restriction can make it challenging to stick to and may lead to boredom and dissatisfaction with the limited food choices. Additionally, the high-fat content of the keto diet may be difficult for some people to tolerate and can lead to constipation and other digestive issues.
Social Isolation and Disordered Eating
The strict nature of the keto diet may lead to social isolation as it can be difficult to find keto-friendly options when dining out or socializing with others. There is also a risk of disordered eating due to the restrictive nature of the diet and the potential for unhealthy weight loss practices.
Pregnancy and Breastfeeding
The keto diet may not be suitable for women who are pregnant or breastfeeding. During pregnancy, the body requires a higher amount of protein, and the keto diet typically provides only around 15% of calories from protein. Additionally, the high-fat content of the keto diet may signal food scarcity to the body, which is not ideal during pregnancy when nutrient needs are increased.
Pre-existing Health Conditions
The keto diet is not recommended for individuals with certain pre-existing health conditions. These include kidney damage, heart disease, liver or pancreatic conditions, gallbladder issues, and type 1 diabetes. The high-fat content of the keto diet can negatively affect individuals with these conditions and lead to adverse health outcomes.
Children and Teens
The keto diet may not be suitable for children and teens as they require a balanced diet to support their growth and development. Unless prescribed and closely monitored by a healthcare provider, the keto diet may cause nutritional deficiencies in this age group. Additionally, there is a risk of delayed puberty and changes in the menstrual cycle for adolescent females.
Athletes
The keto diet may not be ideal for competitive or high-performance athletes as their higher activity levels require more calories and quick fuel sources, which are typically provided by carbohydrates. Research suggests that higher-carbohydrate diets are best suited for athletes to meet their energy demands.

Frequently asked questions
Generally, a person can consume up to 50 grams of carbs per day and stay in ketosis. However, some people might need to go as low as 20 grams to reach ketosis.
A diet with less than 100-150 grams of carbs per day is generally considered low-carb.
Wheat products like rice, pasta, cereals, bread, and baked goods are high in carbs and should be avoided or limited on a keto diet. Some fruits and vegetables, like bananas, potatoes, and carrots, are also high in carbs.
Net carbs refer to the amount of carbs that are absorbed by the body and contribute to calories. On a keto diet, you calculate net carbs by subtracting indigestible carbs (fibre and some sugar alcohols) from total carbs. Net carbs are important because they are the ones that impact ketosis.
To stay within the carb limit, it's important to plan meals ahead of time and track carb intake. Focus on high-fat meats, fish, nuts, and low-carb vegetables. Avoid processed grains, sugar, starchy vegetables, legumes, and most fruits.
