Keto Diet: Understanding Net Carbs And Micronutrient Balance

The keto diet is a low-carb, high-fat diet. The diet involves taking an extremely low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. The keto diet is generally made up of 70 to 75 percent fat, 20 to 25 percent protein, and 5 to 10 percent carbohydrates. The exact number of grams of carbohydrates will be different for everyone, but it is generally around 20 to 50 grams per day. Many people on a keto diet count net carbs, which is the total number of carbohydrates in food that can be absorbed and used by the body for energy. Net carbs are calculated by subtracting dietary fibre and certain sugar alcohols from the total number of carbohydrates.

Net carbs are the total carbs minus fibre and certain sugar alcohols

Net carbs are the total number of carbohydrates in a food or meal minus the fibre and certain sugar alcohols. This is because fibre and some sugar alcohols are not fully absorbed by the body and are either partially broken down or pass through the body unchanged.

To calculate net carbs, you need to know the total amount of carbohydrates in a food or meal, as well as the amount of fibre and sugar alcohols. The formula for calculating net carbs is:

Net carbohydrates = total carbohydrates – fibre – certain sugar alcohols

For example, if a food contains 20 grams of total carbohydrates, 8 grams of fibre, and 1 gram of sugar alcohol, the net carb count would be 11 grams (20 grams of total carbs – 8 grams of fibre – 1 gram of sugar alcohol = 11 grams of net carbs).

It's important to note that not all sugar alcohols are treated equally in this calculation. Erythritol, for instance, can be completely subtracted from the total carbohydrates, whereas other sugar alcohols like maltitol, sorbitol, and xylitol can only be partially subtracted.

Calculating net carbs is particularly relevant for people following a ketogenic diet, as it helps them stay within their carbohydrate target and maintain a state of ketosis. In a keto diet, net carbs are generally limited to 20-50 grams per day.

Total carbs include all carbohydrates present in food

Total carbs refer to all carbohydrates present in food. This includes all three types of carbohydrates: sugars, starches, and fiber. Sugars are simple carbohydrates that are quickly broken down by the body and can cause spikes in blood sugar levels. They are found in fruits, vegetables, milk, candy, desserts, processed foods, and regular soda. Starches are complex carbohydrates made of many simple sugars linked together. They include bread, cereal, pasta, and starchy vegetables like potatoes. Fiber is also a complex carbohydrate that the body cannot fully break down, found in plant-based foods like fruits, vegetables, nuts, seeds, beans, and whole grains.

The total number of carbohydrates in a food or meal can be determined by checking the nutrition label or using a food tracking app. This value includes all types of carbohydrates, whether they are simple or complex, digestible or indigestible. However, it's important to note that the term "net carbs" refers to the number of carbohydrates that are absorbed and used by the body for energy. Net carbs are calculated by subtracting the amount of fiber and sugar alcohols from the total number of carbohydrates.

The keto diet is a low-carb, high-fat diet that aims to bring the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. On a keto diet, people typically count net carbs instead of total carbs to ensure they stay within their carbohydrate target. This involves subtracting the fiber content, which is not digested by the body, from the total carb count. For most keto diets, daily net carb intake is limited to 20-50 grams.

While the keto diet can be effective for weight loss and blood sugar management, it is important to note that it may be challenging to sustain in the long term, especially for those accustomed to consuming high-carb foods. Additionally, the high protein intake associated with the keto diet may increase the risk of kidney stones, and the high-fat intake may negatively impact cholesterol levels for some individuals. As such, it is recommended to consult with a healthcare provider before starting any restrictive diet, including the keto diet, to ensure it is safe and appropriate for your individual needs and health goals.

The keto diet is a low-carb, high-fat diet

On the keto diet, net carbs are counted when calculating daily consumption. Net carbs refer to the amount of carbohydrates in food that can be absorbed and used by the body for energy. To calculate net carbs, the amount of fibre and sugar alcohols is subtracted from the total amount of carbohydrates. This is because fibre and sugar alcohols are not fully absorbed by the body.

The keto diet recommends limiting daily carbohydrate consumption to 20-50 grams to induce ketosis. However, the number of net carbs can vary depending on age, weight, gender, and physical activity.

While the keto diet can be effective for weight loss, it is important to note that it may also have some negative side effects. For example, severely low-carb diets may cause constipation and headaches. Additionally, the restrictive nature of the keto diet may lead to nutritional deficiencies, especially if followed for an extended period.

It is always recommended to consult with a healthcare professional before starting any new diet, including the keto diet, to ensure it is safe and appropriate for your individual needs and health status.

The keto diet originated as a therapeutic diet for epilepsy

The keto diet is a high-fat, low-carbohydrate diet that originated as a therapeutic diet for epilepsy. It was first used in the 1920s to control seizures in people with epilepsy, particularly those whose seizures did not respond to medications. The diet is typically prescribed by a physician and monitored by a dietitian, and it involves carefully measuring calories, fluids, and proteins. The diet is stricter than the modified Atkins diet and usually includes a ratio of 3 to 4 grams of fat for every 1 gram of carbohydrate and protein, which is about 90% of calories from fat.

The name "ketogenic" comes from the fact that the diet produces ketones in the body. Ketones are formed when the body uses fat for energy instead of carbohydrates. While the body usually uses carbohydrates like sugar, bread, and pasta as fuel, the ketogenic diet is very low in carbs, causing the body to use fats as its primary fuel source. Ketones are not dangerous and can be detected in urine, blood, and breath. Higher ketone levels often lead to improved seizure control.

The ketogenic diet has been shown in many studies to be effective in reducing seizures in children with epilepsy. Over half of the children who go on the diet experience at least a 50% reduction in the number of seizures, and some children, around 10-15%, become seizure-free. The diet is usually recommended for children whose seizures have not responded to several different medications. While the classical ketogenic diet is typically not recommended for adults due to its restricted food choices, the modified Atkins diet is a more flexible option that can work for adults.

The ketogenic diet is not usually recommended as a primary anti-seizure option because it requires drastic changes in food intake, and some people may have trouble staying on the diet due to its strict requirements and potential side effects like nausea, constipation, and fatigue. However, it can be a beneficial therapeutic approach for epilepsy, especially for those who do not respond to standard anti-seizure medications.

Counting net carbs can be confusing due to outdated and conflicting information

The concept of net carbs is based on the idea that not all carbohydrates affect the body in the same way. Simple or refined starches and sugars are absorbed rapidly and have a high glycemic index, causing blood sugar levels to rise quickly after eating. On the other hand, the fibre found in whole grains, fruits, and vegetables, moves slowly through the digestive system, and much of it isn't digested at all.

To calculate net carbs, most manufacturers take the total number of carbohydrates in a product and subtract the fibre and sugar alcohols, as these types of carbohydrates are thought to have a minimal impact on blood sugar levels. However, the impact of sugar alcohols on blood sugar and the body is not fully understood, and they may cause problems for some individuals.

Furthermore, there is no legal definition of "net carbs," and the only carbohydrate information regulated by the FDA is provided in the Nutrition Facts label. This lack of standardisation means that the way companies calculate net carbs can differ.

For those following a ketogenic diet, it is generally recommended to consume 20-50 grams of net carbs per day. This equates to 5-10% of the total calorie intake and helps the body achieve and maintain ketosis, a state where the body uses fat for energy instead of carbohydrates.

In conclusion, while counting net carbs can be a useful tool for those on a ketogenic diet, the conflicting information and lack of standardisation can make it challenging to navigate. It is always advisable to consult with a dietitian or healthcare provider before starting any new diet.
