The ketogenic or “keto” diet is a low-carbohydrate, fat-rich eating plan that has been used to treat specific medical conditions. The keto diet aims to put the body into a state of ketosis, where the body burns fat for energy instead of carbohydrates, producing ketones. The number of carbs one can eat and still be in ketosis varies from person to person, but it typically ranges from 20 to 50 grams of total carbs per day. Some people can eat 40 grams of carbs daily and stay in ketosis, while others need to stick to 20 grams. To determine one's carb limit, it is recommended to start with 20 grams of net carbs per day and gradually increase by 5 grams every three days while monitoring ketosis levels.

The keto diet is a low-carb, high-fat diet that causes the body to enter ketosis
To achieve ketosis, the general guideline for the keto diet is to consume less than 20 grams of net carbs per day. However, some individuals may need to restrict their carb intake even further, to around 35 grams or below, to enter and maintain ketosis. This variation is due to individual differences, as everyone has a unique carb limit that triggers ketone production.
While the keto diet emphasizes high-fat foods, it also includes moderate protein intake. Excess protein can prevent ketosis, as amino acids in protein can be converted to glucose. Therefore, it is crucial to monitor protein consumption while on the keto diet.
Maintaining a keto diet can be challenging due to its restrictive nature. It requires eliminating a wide range of foods, including starches, grains, fruits, and some vegetables. However, the diet offers flexibility in terms of personal preferences and health goals. Some individuals may opt for a cyclical ketogenic diet, which involves cycles of low-carb and high-carb days, or a targeted ketogenic diet, allowing for higher carb intake around high-intensity workouts.
It is important to note that the keto diet may not be suitable for everyone, and individual results may vary. Before making significant dietary changes, consulting a healthcare professional is advisable to ensure it aligns with one's health goals and conditions.

To stay in ketosis, aim for under 50 grams of carbs per day
The keto diet is a low-carb, high-fat eating plan that has been used to treat various medical conditions, including epilepsy and diabetes. The diet works by depriving the body of glucose, which is obtained from eating carbohydrates, and instead forcing it to burn fat for energy, thereby producing ketones. This state is called ketosis.
To stay in ketosis, it is recommended that a person consumes under 50 grams of carbohydrates per day. However, this number may vary depending on individual factors, with some sources recommending a maximum of 35 grams or even 20 grams of carbohydrates per day to guarantee ketosis.
The keto diet is very restrictive, and it can be challenging to stay within the recommended carbohydrate limit. For example, a single serving of regular bread, pasta, rice, or potato can easily exceed the daily carb limit and take you out of ketosis. Therefore, it is recommended to aim for carbs from whole, unprocessed foods, such as vegetables, nuts, and berries, which are lower in carbohydrates and provide essential vitamins and minerals.
It is important to note that the keto diet is not suitable for everyone, and some people may experience gastrointestinal issues or boredom with the limited food options. Additionally, the diet should be approached gradually and with regular health monitoring, especially for those with pre-existing medical conditions like diabetes.
To find your personal carb limit for ketosis, it is recommended to consult a healthcare professional and consider factors such as your weight loss goals, overall well-being, and individual variability.

Net carbs are calculated by subtracting fibre and half the sugar alcohol content from the total carb count
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. The standard keto diet consists of 70% fat, 20% protein, and 10% carbs. To stay in ketosis, a person can consume up to 50 grams of carbs per day, though some sources suggest limiting it to fewer than 20 grams. This varies depending on individual factors such as activity level, insulin resistance, and dietary history.
Net carbs refer to the carbohydrates that are absorbed by the body and are calculated differently for whole foods and packaged products. When calculating net carbs for whole foods, you subtract the fibre from the total number of carbs. For example, a medium avocado contains 17.1 grams of total carbs, 13.5 grams of fibre, resulting in 3.6 grams of net carbs (17.1 grams of total carbs – 13.5 grams of fibre = 3.6 grams of net carbs).
For packaged products, you subtract the fibre and half the sugar alcohol content from the total carb count. Sugar alcohols are sweet-tasting compounds found in sugar substitutes that are not digested in the same way as regular sugar. Erythritol is an exception; if it is the only sugar alcohol in the ingredients list, its carbs can be completely subtracted from the total carbs.
For example, a keto pancake with 13 grams of total carbohydrates, 9 grams of fibre, 2 grams of erythritol, and 1 gram of allulose would have 1 gram of net carbohydrate (13 grams – 9 grams – 2 grams – 1 gram = 1 gram). This information can be found on the nutritional labels of food products.

Some people can remain in ketosis with a higher carb intake, while others must restrict carbs to under 35 grams
The keto diet is a low-carb, high-fat eating plan designed to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. Ketosis is achieved when the body produces ketones, which happens when glucose levels drop due to a restricted carbohydrate intake.
There is no definitive carb limit for keto, as this varies from person to person. The general guideline is to stay under 20 grams of carbs per day to be in ketosis. However, some people may be able to remain in ketosis with a slightly higher carb intake, up to 50 grams per day. This is because every person has a different threshold for ketone production, and factors such as activity level and insulin sensitivity play a role.
For some, staying under 35 grams of carbs per day is necessary to maintain ketosis. This may be due to individual differences in metabolism, or because other factors in their diet or lifestyle are impacting their ability to stay in ketosis. For example, eating too much protein can prevent ketosis, as the amino acids in protein can be converted to glucose. Additionally, stress and a lack of exercise can impair the body's ability to adapt to the keto diet.
Some people find that a strict keto diet of under 20 grams of carbs per day is challenging to maintain, and they may experience gastrointestinal issues or boredom with the limited food options. In these cases, a less restrictive low-carb diet of around 30 to 40 grams of carbs per day may be a more sustainable option, especially if it still allows them to lose weight and feel good.
It is important to note that the keto diet can be challenging to follow and may not be suitable for everyone. It is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as keto.

Keto-friendly foods include meat, fish, eggs, vegetables, nuts, berries, and high-fat dairy
The keto diet is a low-carb, high-fat diet that restricts several types of foods. The diet limits carbohydrates and replaces them with fats, putting the body into a state of ketosis. To reach and maintain ketosis, a metabolic state in which your body burns fat for fuel instead of carbohydrates, a person should eat fewer than 50 grams of net carbs per day. However, some sources suggest that fewer than 20 grams of net carbs per day is the threshold for ketosis.
Non-starchy vegetables that are low in calories and carbohydrates, such as broccoli, cauliflower, green beans, bell peppers, zucchini, and leafy greens, are recommended on the keto diet. These vegetables are packed with vitamins, minerals, and fiber, which is important for digestive health. However, it is important to note that even though these vegetables are low in carbs, consuming too many servings in a day can knock you out of ketosis.
Nuts and berries are also keto-friendly but should be consumed in moderation as they have more grams of carbs per serving compared to vegetables. For example, one cup of raspberries and 3/4 cup of blueberries add up to 20 grams of net carbs. Similarly, one cup of walnut halves and 1 1/2 cups of hazelnuts also amount to 20 grams of net carbs.
High-fat dairy products are encouraged on the keto diet, such as whole milk yogurt, cheeses, and butter. These foods help reduce carb intake and maintain a keto-friendly macronutrient ratio. For example, a 6-ounce serving of whole milk plain Greek yogurt contains 6.77 grams of carbs, 15.3 grams of protein, and 5 grams of fat.
