The ketogenic diet is a popular low-carb, high-fat diet that has been used for decades to help with weight loss and manage certain health conditions. To achieve ketosis, a metabolic state where the body uses stored fat as its primary energy source, it is generally recommended to keep your daily carb intake under 50 grams, and for some, as low as 20-30 grams. Maintaining this low-carb intake helps your body switch to burning fat for fuel, leading to weight loss and other health benefits.
However, it's important to note that the amount of carbs you should consume on keto may vary depending on individual factors such as activity level, weight goals, age, gender, and health conditions. It's always recommended to consult a healthcare professional or dietitian for personalized guidance.

To stay in ketosis, keep your daily carb intake under 50 grams
To stay in ketosis, it is recommended to keep your daily carb intake under 50 grams. The ketogenic diet is a popular low-carb, high-fat diet that has been used to help with weight loss and manage certain health conditions. By reducing carb intake, the body is forced to burn fat for energy instead of carbs, causing a drop in glucose levels. This shift in metabolism leads to weight loss and other health benefits.
Maintaining a daily carb intake of under 50 grams can be challenging as it requires a significant reduction in carbohydrates. This means avoiding high-carb foods such as sugary treats, starchy vegetables, fruits, bread, pasta, and rice. However, it is important to note that not all carbs need to be removed from your diet. Net carbs, which are absorbed into the body, are the most important to consider. Focus on keeping your net carb intake under 50 grams per day, while still including essential fiber in your diet.
To achieve and maintain ketosis, it is crucial to accurately track your carb intake. This can be done by reading food labels and calculating net carbs. Net carbs are calculated by subtracting dietary fiber and half the amount of sugar alcohols from the total carbohydrate amount. Additionally, tools like MyFitnessPal and Carb Manager can help you stay within your daily carb limit.
It's important to note that the specific amount of carbs you need depends on your individual goals, body composition, and health needs. Consulting with a healthcare professional or dietitian can provide personalized guidance on your daily carb intake.

For some, as little as 20-30 grams of carbs per day is required to achieve ketosis
To achieve ketosis, it is recommended to keep your daily carb intake under 50 grams. However, for some, a much lower intake of 20-30 grams of carbs per day is necessary to reach this state. This stricter limit is often referred to as the "strict keto diet" or "strict low-carb approach".
Ketosis is a metabolic state where the body uses stored fat as its primary energy source instead of carbohydrates. This shift in metabolism is achieved by following a low-carb diet, forcing the body to burn ketones (from fat) for fuel instead of glucose (from carbs). The keto diet is particularly effective for weight loss and offers other health benefits such as reduced blood sugar and insulin levels, and improved mental focus.
It is important to note that the number of carbs needed to achieve ketosis can vary from person to person. Factors such as activity level, weight goals, age, gender, and health conditions can influence the ideal carb intake. Therefore, it is always recommended to consult a healthcare professional or dietitian for personalized guidance.
Additionally, it is crucial to accurately track your carb intake to ensure success on the keto diet. Various tools and apps, such as Carb Manager and MyFitnessPal, can assist in monitoring your carb consumption and staying within the recommended limits.

Net carbs = total carbs – dietary fibre – half of sugar alcohols
To achieve ketosis, it is recommended to consume under 50 grams of net carbs per day. This is calculated by subtracting fibre and sugar alcohols from the total amount of carbohydrates.
Net carbs are the number of carbohydrates that are absorbed by your body. The formula for calculating net carbs is: Net carbs = total carbs – dietary fibre – half of sugar alcohols.
Dietary fibre is a form of carbohydrates that is not absorbed in the small intestine. Instead, it passes directly into the colon and provides no calories or effects on blood sugar and insulin levels. Insoluble fibre creates bulkier stools and can help prevent constipation, while soluble fibre dissolves in water and can help lower cholesterol and control blood sugar levels.
Sugar alcohols are sweeteners that have similar tastes and textures to sugar but with fewer calories and a less significant effect on blood sugar levels. They are often used in sugar-free or diet products. Erythritol, for example, has 70% of the sweetness of sugar but only 5% of the calories. Sugar alcohols are only partially absorbed in the small intestine, and the amount absorbed varies depending on the type.
When calculating net carbs, you subtract the grams of dietary fibre and half the grams of sugar alcohols from the total number of carbohydrates. This value may differ from the net carb value stated on product labels, as some companies subtract all fibre and sugar alcohol carbs when calculating net carbs.
For example, let's say a packaged food product has 23 grams of total carbs, 9 grams of fibre, and 11 grams of sugar alcohols. Using the formula, we calculate:
23 grams total carbs – 9 grams fibre – 5.5 grams sugar alcohols (half of 11 grams) = 8.5 grams net carbs.
This calculation can help individuals on a ketogenic diet manage their carb intake and ensure they stay within the recommended limit to maintain ketosis.

A very active person is more likely to be able to consume more carbs and stay in ketosis
The ketogenic diet is a popular low-carb, high-fat diet that has been used for decades to help with weight loss and manage certain health conditions. To succeed on keto, it’s essential to know your daily carb limit to keep your body in a state of ketosis. Ketosis is a metabolic state where the body uses stored fat as its primary energy source instead of carbohydrates.
Most keto diet guidelines recommend keeping your daily carb intake under 50 grams to stay in ketosis. However, this number can vary depending on individual needs and activity levels. If you're a very active person who exercises regularly, you're more likely to be able to consume more carbs and still stay in ketosis. On the other hand, if you lead a sedentary lifestyle, it's best to keep your carb intake on the lower end, between 20-30 grams, to ensure you achieve ketosis.
- Focus on net carbs: Net carbs are absorbed into your body and include carbohydrates like fiber and sugar alcohols. On keto, aim for no more than 50 grams of net carbs per day.
- Track your carb intake: Use tools like MyFitnessPal or Carb Manager to monitor your carb intake and stay within your limits.
- Choose the right foods: Avoid high-carb foods like sugary treats, starchy vegetables, bread, rice, and pasta. Opt for low-carb options such as non-starchy vegetables, nuts, seeds, and healthy oils.
- Be mindful of portion sizes: Even when choosing keto-friendly foods, it's important to watch your portions to ensure you don't exceed your carb limit.
By following these guidelines and tailoring your carb intake to your activity level, you can maximise your chances of staying in ketosis and achieving your health and fitness goals.

High-carb foods to avoid include most fruits, pasta, potatoes, candy bars, pastries, donuts, and more
A keto diet is an extremely low-carb, high-fat diet. The goal is to achieve a metabolic state of ketosis, where the body burns fat instead of carbs for energy. While there is no strict definition of a low-carb diet, anything under 100-150 grams of carbs per day is generally considered low-carb. However, to get into ketosis, most people will need to go under 50 grams per day.
High-carb foods to avoid on a keto diet include:
- Bread, pasta, rice, and other refined carbs.
- Beer and mixed drinks.
- Honey and syrups like maple syrup or agave.
- Juice.
- Sodas.
- Glazed or honey-baked ham.
- Light or low-fat margarine.
- Dried fruit or trail mix.
- Low-fat diet foods, such as low-fat yoghurt, low-fat mayonnaise, low-fat salad dressings, reduced-fat peanut butter, and reduced-fat or skim milk.
- Potatoes and other starchy vegetables, such as peas and corn.
- Sweetened yoghurt or dairy.
- Certain fresh fruits, such as mangoes, bananas, and grapes.
- Beans and other legumes.
- Quinoa and other grains.
- Dark chocolate (only keto-friendly in small amounts).
- Milk and white chocolate.
It's important to note that the keto diet is not just a low-carb diet, but also a high-fat diet. This means that while certain fruits and vegetables are high in carbs, they can be consumed in moderation as part of a keto diet. Additionally, there are low-carb alternatives to traditional high-carb foods, such as zucchini noodles or cauliflower rice, that can be incorporated into a keto diet.

Frequently asked questions
To stay in ketosis, a person should consume up to 50 grams of carbs per day. However, some people might need to go as low as 20 grams to reach ketosis.
Net carbs are the carbs absorbed into your body. Not all carbohydrates are absorbed – fiber and sugar alcohols, for example, are not. Therefore, net carbs are usually lower than total carbs.
To calculate net carbs, subtract the amount of dietary fiber and half the amount of sugar alcohols from the total number of carbs.
Meat such as beef, veal, lamb, pork, chicken, and turkey, and fish such as cod, sardines, tuna, and salmon have very low net carbs. Most green and leafy vegetables also have a low keto net carb count.
It is best to keep carb intake below 50 grams on a cheat day to avoid disrupting ketosis.
