Keto Diet: Understanding The 50 Net Carb Limit

The keto diet is a high-fat, moderate-protein, and low-carb eating plan. The number of carbs one can consume and still be in ketosis depends on individual factors such as exercise regime, stress levels, and bio-individuality. However, it is generally agreed that 50 grams of carbs per day is an acceptable amount for those on the keto diet. This is because ketosis – the fat-burning metabolic state where fat is used as the main energy source – can be achieved at this level of carb intake.

The keto diet is a high-fat, moderate-protein, very low-carb eating plan

The keto diet involves a significant reduction in carbohydrate intake, with foods like grains, sugar, fruit, and tubers being restricted. Instead, the diet focuses on high-fat foods such as meats, leafy greens, above-ground vegetables, high-fat dairy, nuts, seeds, avocados, and berries, and healthy fats like coconut oil and olive oil.

While keto can be an effective approach for weight loss and has been shown to have benefits for certain health conditions, it is important to note that it may not be suitable for everyone. The restrictive nature of the diet can make it challenging to follow and may lead to nutritional deficiencies if not carefully planned. Additionally, the high levels of saturated fat associated with keto may pose risks for long-term heart health. As such, it is important to consult with a healthcare professional before starting any new diet, especially one as restrictive as keto.

For those interested in trying the keto diet, it is recommended to start with a lower carb limit, typically around 20 grams of net carbs per day, to allow the body to adjust and ensure ketosis. After a few months, it is possible to gradually increase carb intake and monitor ketone levels to find your personal carb limit. This process involves testing ketone levels at different carb intake levels and may take some time to determine the optimal range for ketosis.

Net carbs are calculated by subtracting the grams of fibre from the total grams of carbs

The keto diet is a high-fat, moderate-protein, and very low-carb eating plan. The diet is designed to put the body into a state of ketosis, where fat is burned instead of glucose. The number of grams of carbohydrates consumed per day on a keto diet varies from person to person but is generally around 20 to 50 grams per day.

Some sources suggest that 20 grams of net carbs per day is the best way to get into ketosis and stay there. However, this number may be as high as 50 grams per day for some people. It is recommended that beginners to the keto diet stick to 20 grams of net carbs per day for three months before increasing their carb intake.

To calculate net carbs, simply subtract the grams of fibre from the total grams of carbs. For example, a medium red bell pepper has 7 grams of total carbs and 2.5 grams of fibre. Therefore, the net carbs in a red bell pepper are 4.5 grams.

It is important to note that net carbs are not the only factor that affects ketosis. Exercise, stress, and protein intake can also impact whether a person remains in ketosis. Additionally, not all carbohydrates are equal; complex carbs from plant-based foods or low-glycemic fruits are preferred over simple sugars.

In summary, net carbs are calculated by subtracting fibre from total carbs, and this metric is important for people on the keto diet to monitor their carbohydrate intake and ensure they remain in ketosis.

To enter ketosis, it is recommended to eat fewer than 20 grams of net carbs each day

On the keto diet, you must keep carbs low. Keeping carbs low helps keep blood sugar and insulin levels low, triggering the fat-burning state of ketosis. Ketosis underpins the keto diet's benefits, including weight loss, hunger control, clearer cognition, and lower inflammation.

To calculate your net carb intake, subtract the total fiber intake from the total carbs. For example, one California avocado contains 11.7 grams of total carbohydrates. However, 9.2 grams of those carbs are fiber carbs, resulting in 2.5 grams of net carbs—well within the keto-approved limit.

While it is recommended to keep net carbs below 20 grams, this number can vary depending on individual goals. For instance, if you are using the keto diet therapeutically to manage epilepsy, you should aim for net carbs close to zero. On the other hand, most people can be more flexible, and keeping net carbs at 5-10% of daily calories (15 to 30 grams) is a good starting point.

It is important to note that not all carbs need to be limited on the keto diet. Fiber, for example, does not raise your blood sugar and is therefore not included in net carb calculations. Additionally, some sweeteners are considered keto-friendly and do not raise blood sugar levels, so they can also be subtracted from the total carb count.

By focusing on limiting net carbs, you can enjoy a variety of nutrient-dense foods while still adhering to the keto diet. For example, you can include avocados, berries, nuts, and many low-carb vegetables in your diet. These foods are not only satisfying but also packed with vitamins and minerals.

In contrast, high-carb foods like bread, potatoes, pasta, and rice can quickly exceed your daily carb limit and take you out of ketosis. Therefore, it is recommended to opt for keto-friendly alternatives, such as cauliflower rice or zucchini noodles, to satisfy your cravings without compromising your carb intake.

In summary, to enter and maintain ketosis, it is crucial to limit your net carb intake to fewer than 20 grams per day. This can be achieved by being vigilant about your food choices, tracking your carb intake, and opting for keto-friendly alternatives to high-carb foods. By doing so, you can reap the benefits of ketosis while still enjoying a diverse and nutritious diet.

Non-starchy vegetables like spinach, chard and broccoli do not impact ketosis

Non-starchy vegetables are an essential part of a healthy low-carb diet. They are low in overall carbohydrates and calories, and provide vital nutrients such as vitamins, minerals, and fibre.

Leafy greens such as spinach, chard, and kale are non-starchy vegetables that are suitable for a keto diet. Spinach, for example, has only 3g net carbs per cooked cup and almost no digestible carbs raw. Chard is also keto-friendly, with 0.5 cups containing 1.8g net carbs. Similarly, kale is another nutrient-dense green that is low in carbs and high in vitamins A and C.

Cruciferous vegetables like broccoli are also a great option for those on a keto diet. Broccoli is packed with vitamins C and K and has only 4g net carbs per cup. It is a versatile vegetable that can be added to various dishes, including salads, stir-fries, and soups.

In addition to the aforementioned vegetables, cauliflower, zucchini, lettuce, and cucumbers are other non-starchy, low-carb options to consider.

The keto diet can be used to control seizures in people with epilepsy

The ketogenic diet has been shown to be effective in reducing or preventing seizures in many children with epilepsy, with over half of children who go on the diet experiencing at least a 50% reduction in the number of seizures. Some children, around 10-15%, even become seizure-free. The diet can also be used in adults with epilepsy, although it is usually not recommended due to the restricted food choices making it difficult to follow. However, the modified Atkins diet, which is less restrictive, has been found to be effective in adults.

The exact mechanism by which the ketogenic diet reduces seizures is not fully understood, but it is believed to be related to the production of ketones and the resulting changes in chemical messengers and neuronal metabolic activity. The diet also reduces inflammation in the brain and alters the gut microbiome, which may contribute to its anti-seizure effects. Additionally, the ketogenic diet can increase the synthesis of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter that helps to suppress the spread of excitability in the brain, making it less likely for a seizure to occur.

Overall, the ketogenic diet can be a safe and effective way to control seizures in people with epilepsy, particularly in children with drug-resistant epilepsy. However, it is important to carefully plan and monitor the diet, as it can be restrictive and may lead to nutritional deficiencies if not properly managed.
