Carb Counting: Are 15 Grams Too Many For Keto?

The keto diet is a high-fat, low-carb diet that aims to put the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. To stay in ketosis, a person should consume no more than 50 grams of net carbs per day, and the fewer carbs, the better. Net carbs are calculated by subtracting dietary fiber and half of any sugar alcohols from the total carb content. For this reason, it is important to monitor your total carb intake and choose low-carb foods to stay within the daily limit.

The keto diet recommends a maximum of 50g of carbs per day

The keto diet is a very low-carb, high-fat diet that puts the body into a state of ketosis. Ketosis is when the body burns fat for fuel instead of carbohydrates, its preferred energy source. To stay in ketosis, the keto diet recommends consuming no more than 50 grams of net carbs per day. Net carbs are calculated by subtracting the amount of dietary fibre and half the amount of sugar alcohols from the total number of carbs. This calculation ensures that the body absorbs the right amount of carbs to stay in ketosis.

The number of net carbs can vary depending on the food. For example, a cup of rice or pasta has 50 grams of net carbs, while a cup of cherry tomatoes, two large zucchini, and three large red peppers also have 50 grams of net carbs. It is important to note that not all carbs are created equal, and the keto diet restricts carbohydrates from healthy foods such as fruits, whole grains, and some vegetables.

Some people may find it challenging to stay within the 50-gram limit, as it leaves limited carb options, mainly vegetables and small amounts of berries. Additionally, the keto diet may not be suitable for everyone, especially those with certain chronic health conditions. It is always recommended to consult a doctor or a registered dietitian before starting any new diet, especially a restrictive one like keto.

While the keto diet recommends a maximum of 50 grams of net carbs per day, some sources suggest that consuming fewer than 20 grams of net carbs is almost certain to keep an individual in ketosis. This stricter limit may be necessary for those who are not as sensitive to insulin or are not as active, as these factors can impact the ability to stay in ketosis.

Net carbs are absorbed into the body

Net carbs are the number of carbohydrates that are absorbed by your body and have an impact on your blood sugar levels. To calculate net carbs, you take the total number of carbs and subtract the amount of fibre and sugar alcohols. This is because fibre is not absorbed in the small intestine and passes through the body unchanged, and sugar alcohols are only partially absorbed into the bloodstream.

The number of net carbs in a food product can be calculated by using the following equation:

Net carbs = Total Carbs – Fibre – Sugar Alcohols

For example, a medium avocado contains 17.1 grams of total carbs, 13.5 grams of fibre, and 3.6 grams of net carbs.

The Atkins Diet, which is a low-carb diet, recommends counting net carbs as they represent the total carbohydrate content of food minus the fibre content. Net carbs are the only carbs that significantly impact your blood sugar level and are, therefore, the only carbs that need to be counted on the Atkins Diet.

The keto diet also involves calculating the number of net carbs in food products. The keto diet is a very low-carb diet, limiting carbohydrates to up to 50 grams per day and replacing them with fats. This puts the body into a state of ketosis, where it burns fat instead of carbs for energy.

To summarise, net carbs are the number of carbohydrates that are absorbed by the body and are calculated by subtracting fibre and sugar alcohols from the total number of carbs. This calculation is important for people following low-carb diets such as Atkins and keto, as it helps them monitor their carbohydrate intake and maintain the desired state of ketosis.

Total carbs are not always absorbed

When following a keto diet, it is crucial to understand the difference between net carbs and total carbs. The keto diet is a low-carb, high-fat diet that aims to bring the body into a state of ketosis. To achieve and maintain ketosis, a person should consume up to 50 grams of net carbs per day. However, this number can vary depending on individual factors such as age, weight, gender, and physical activity.

To calculate net carbs, you need to determine the total amount of carbohydrates in a food or meal and then subtract the amount of fiber. If the food is processed, you may also need to subtract half of the sugar alcohol content. Net carbs provide a more accurate representation of the digestible carbs you are consuming and help ensure you stay within your carbohydrate target.

By focusing on net carbs instead of total carbs, you can make more informed choices about the types and amounts of carbohydrates you include in your keto meals. This distinction is particularly important when it comes to high-fiber foods, as the fiber content can significantly impact the total carb count. For example, a food with 20 grams of total carbohydrates and 8 grams of fiber would have a net carb count of 12 grams.

In addition to calculating net carbs, it is also important to consider the quality of the carbohydrates you are consuming. Whole, unprocessed foods are generally recommended over processed options, as they provide additional nutrients and can help promote overall health.

Non-starchy vegetables are best for keto

The keto diet is a low-carbohydrate, high-fat diet that puts the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. This means that the diet is largely based on fat, with very low levels of carbohydrates.

To stay in ketosis, a person needs to consume under 50 grams of carbohydrates per day. However, to be almost certain to enter ketosis, some sources recommend consuming fewer than 20 grams of net carbs each day. This means that a keto meal should contain no more than 15 grams of carbs.

Vegetables are an essential part of any diet, but not all vegetables are created equal when it comes to keto. Starchy vegetables, such as potatoes, corn, carrots, beets, and squash, are high in carbohydrates and should be avoided. On the other hand, non-starchy vegetables are best for keto and can be consumed freely and in large quantities.

• Broccoli: 3-4 grams of net carbs per serving
• Arugula: 2 grams of net carbs per serving
• Asparagus: 2 grams of net carbs per serving
• Bell Peppers: 3-4 grams of net carbs per serving
• Brussels Sprouts: 3-5 grams of net carbs per serving
• Cauliflower: 3 grams of net carbs per serving
• Kale: 1-3 grams of net carbs per serving
• Mushrooms: 2 grams of net carbs per serving
• Spinach: 1-4 grams of net carbs per serving
• Tomatoes: 3-4 grams of net carbs per serving

These non-starchy vegetables provide the body with essential nutrients, antioxidants, and fiber, while keeping carb counts low.

When choosing keto-friendly vegetables, it is also helpful to remember that above-ground vegetables are generally lower in carbs than below-ground vegetables, which are root vegetables and tend to be higher in starch.

So, if you're aiming for a keto meal with 15 grams of carbs or fewer, non-starchy vegetables are the way to go. You can enjoy a variety of these vegetables and stay well within your carb limit, reaping the benefits of a keto diet.

Keto is not suitable for everyone

The keto diet is a very-low-carb, moderate-protein, and high-fat diet. It is designed to switch the body from burning carbohydrates to burning fat, a state called ketosis. While the keto diet has many research-backed benefits, it is not suitable for everyone.

Personal Readiness

Some people may find it difficult to give up carbs, and the keto diet can be too restrictive for some people's lifestyles. Research suggests that health counselling only benefits people who are willing to change and embrace healthy behaviours. In other words, no amount of information will motivate someone to try a keto diet if they are not personally ready for it.

Food Preferences and the Keto Flu

The keto diet can cause intense hunger and sugar cravings within the first few days, as well as other "keto flu" symptoms like fatigue and headaches. These symptoms may be off-putting to some people.

Current Health Condition and Medication

Although the keto diet can help people with diabetes, it is important to consult a healthcare provider before starting the diet, especially if you are taking blood glucose-lowering medications. Your healthcare provider may need to adjust your medications to prevent dangerously low blood glucose, as keto already lowers blood glucose.

Pregnancy or Nursing

There has not been much research into the effects of the keto diet during pregnancy. However, studies have found that side effects can include weight loss, deficiencies in important nutrients, anemia, dehydration, hormonal changes, constipation, and inadequate growth in children. Therefore, the keto diet is risky for pregnant women.

Thyroid Disorder or Adrenal Fatigue

A moderate low-carb diet might be suitable for certain people with thyroid disorders, but a very low-carb diet like keto may worsen some thyroid-related symptoms, including brain fog, trouble sleeping, digestive issues, and changes in mood.

History of Kidney Stones or Kidney Disease

The keto diet is associated with an increased risk of kidney stones, so it is not recommended for people who are prone to kidney disease.

Enzyme Defect or Deficiency

The two most serious contraindications to the keto diet are pyruvate carboxylase deficiency and porphyria, which are rare disorders involving problems with lipid metabolism and the production of heme, a component of hemoglobin. Following the keto diet with these deficiencies can cause dangerous complications, including nervous system deterioration, mental changes, and irregular heartbeats.
