Keto Carb Control: How Many Carbs Are Allowed?

The ketogenic (keto) diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. The keto diet is especially useful for losing excess body fat without hunger, and for improving type 2 diabetes or metabolic syndrome. On a keto diet, you cut back significantly on carbohydrates, also known as carbs, in order to burn fat for fuel. To enter and remain in ketosis, you’ll need to eat less than 50 grams of net carbs each day. This significantly differs from other low-carb diets, which typically restrict carb intake to less than 130 grams per day.

Keto diet plans: standard, cyclical, targeted, and high-protein

The ketogenic (keto) diet is a high-fat, low-carb diet that puts the body into a state of ketosis, which causes it to use fat for energy instead of glucose. There are several variations of the keto diet, including the standard, cyclical, targeted, and high-protein keto diets. Here's an overview of each:

Standard Keto Diet (SKD)

The standard keto diet is the most popular form, where people typically restrict carbs to up to 50 grams per day and focus on high-fat, low-carb food choices. Overall, about 70% of a person's intake is fat, 20% is protein, and 10% is carbs. This diet has been the subject of most research, and it is generally recommended by experts.

Cyclical Keto Diet (CKD)

The cyclical keto diet involves adhering to a standard keto diet protocol for 5-6 days a week, followed by 1-2 days of higher carb intake. During the standard keto days, people should consume 20-50 grams of carbs per day, with healthy fats delivering 65-90% of their total calorie intake. On the higher-carb days, also known as "refeeding days," people increase their carb consumption to break ketosis temporarily. This type of keto diet is popular among those seeking muscle growth and improved exercise performance.

Targeted Keto Diet (TKD)

The targeted keto diet is similar to the standard keto diet, with the main difference being the timing of carb consumption. On a targeted keto diet, people consume their daily allotment of carbs before, during, or after a workout. This approach may enhance exercise performance by providing a small number of fast-absorbing carbs to fuel intense workouts and replenish glycogen stores. The targeted keto diet is designed for athletes but can also work for anyone who performs hard, glycogen-depleting exercises.

High-Protein Keto Diet

The high-protein keto diet is a variation where people consume slightly less fat and more protein compared to the standard keto diet. Overall, about 60% of a person's intake is fat, 35% is protein, and 5% is carbs. This diet can be an effective way to lose weight and improve health, as research suggests that high-protein diets can increase feelings of fullness and make it easier to maintain a calorie deficit.

General Guidelines for Keto Diets

Regardless of the specific type of keto diet, there are some general guidelines to follow. It's important to choose healthy, nutrient-dense foods and monitor your intake of net carbs, which is calculated by subtracting the amount of fiber from the total number of carbs in a serving. Additionally, it's recommended to aim for whole, unprocessed foods to benefit from their vitamins and minerals. Before starting any keto diet, it's crucial to consult with a healthcare professional to ensure it's safe and suitable for your individual needs and goals.

Keto diet food swaps

The keto diet is a low-carb, high-fat diet. It is designed to put the body into a state of ketosis, where fat is burned for fuel instead of carbohydrates. To stay in ketosis, a person should consume no more than 50 grams of carbohydrates per day. This can be challenging, as it means cutting out a lot of foods that are high in carbs, such as bread, rice, pasta, potatoes, and some fruits and vegetables. However, there are some clever food swaps that can help you stay on track with the keto diet. Here are some ideas:

Pizza

Use almond flour instead of regular flour to make the dough. Combine 2/3 cup almond flour with 1 large egg, 2 cups shredded and melted mozzarella, and 2 ounces melted cream cheese.

Rice

Use cauliflower rice instead of regular rice. It's a versatile ingredient that can be used in dishes like stuffing, twice-baked "potatoes", and keto lasagna.

Pasta

Use zucchini noodles, spaghetti squash, steamed spinach, or shitake noodles as a substitute for regular pasta.

Mashed potatoes

Try mashed cauliflower, broccoli, kohlrabi, or turnip as a low-carb alternative.

Chips

Make your own chips at home using pork rinds, baked cheese, or zucchini.

Fries

Jicama, zucchini, and turnip fries are all keto-friendly alternatives to regular fries.

Flour

When baking, use almond flour, pork rinds, psyllium husk, or coconut flour instead of wheat flour.

These swaps can help you stay within the strict carb limits of the keto diet while still enjoying some of your favourite foods. However, it's important to note that the keto diet is very restrictive and may not be suitable for everyone. It's always a good idea to consult a doctor or dietitian before starting any new diet.

Keto diet health benefits

The ketogenic (keto) diet is a low-carb, high-fat diet that has been used for centuries to treat specific medical conditions. It has been clinically proven to promote effective and significant weight loss and improve conditions such as obesity, high blood pressure, and cardiovascular disease.

Weight Loss

The keto diet is well known for its ability to promote weight loss. By drastically reducing carbohydrate intake, the body is forced to burn stored fat for fuel, resulting in significant weight loss over time. This weight loss can lead to improved energy levels and increased confidence.

Improved Blood Sugar Control

The keto diet is particularly beneficial for people with type 2 diabetes or metabolic syndrome. By reducing carbohydrate intake and increasing fat intake, blood sugar levels can be stabilized and insulin sensitivity improved. In some cases, medication for diabetes may need to be adjusted as blood sugar levels regulate.

Enhanced Metabolic Health

The keto diet has been shown to improve several markers of metabolic health, including blood pressure, blood sugar, HDL cholesterol, and triglyceride levels. This can lead to a reduced risk of cardiovascular disease and improved overall health.

Reduced Risk of Seizures

The keto diet was originally developed to treat epilepsy by reducing the risk of seizures. By altering the body's fuel source from glucose to ketones, the diet can help reduce the frequency and severity of seizures in people with epilepsy.

Potential Cancer Treatment

Researchers are exploring the use of the keto diet as a potential supplementary treatment for certain cancers. The high-fat, low-carb nature of the diet may help slow tumor growth and improve patient outcomes when used in conjunction with traditional cancer treatments.

Improved Brain Function

The keto diet has been found to improve brain function and cognitive performance. By increasing the production of ketones, which the brain can use for energy, the keto diet can enhance focus, concentration, and mental clarity.

It is important to note that while the keto diet offers these potential health benefits, it also has some risks and side effects. It is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as the keto diet. Additionally, the keto diet may not be suitable for everyone, and individual results may vary.

Keto diet side effects

The keto diet is a low-carb, high-fat diet that can be effective for weight loss and certain health conditions. However, there are some potential side effects to be aware of. Here are some of the most common keto diet side effects:

• Keto flu: In the first few weeks of the keto diet, you may experience flu-like symptoms such as headaches, dizziness, fatigue, nausea, and constipation due to dehydration and electrolyte imbalances as your body adjusts to ketosis.
• Kidney stress: The high intake of animal foods on the keto diet can cause your blood and urine to become more acidic, leading to an increased risk of kidney stones and a potential worsening of chronic kidney disease.
• Digestive issues: The keto diet restricts carbs, making it difficult to meet your daily fiber needs. This can lead to digestive discomfort and constipation.
• Nutrient deficiencies: The keto diet restricts nutrient-dense fruits, whole grains, and legumes, and may not provide recommended amounts of vitamins and minerals such as calcium, vitamin D, magnesium, and phosphorus.
• Low blood sugar: While low-carb diets can help manage blood sugar levels in people with diabetes, they may also increase the risk of hypoglycemia, especially in individuals with type 1 diabetes.
• Bone health: The keto diet has been associated with impaired bone health, including reduced bone mineral density and increased risk of bone fractures.
• Chronic diseases and early death: Some evidence suggests that high-fat, low-carb diets focusing on animal foods may lead to poor health outcomes and increased risk of heart disease, cancer, and all-cause mortality.

How to calculate net carbs

Net carbs refer to the amount of carbohydrates that are absorbed by your body. The calculation for net carbs is considered controversial by some in the low-carb community, and the term "net carbs" is not recognised by the FDA, which recommends using total carbohydrates listed on food nutrition labels.

To calculate net carbs, you subtract the amount of fibre from the total number of carbs. Fibre is a type of complex carbohydrate that the body cannot digest. It passes directly into the colon and then leaves the body.

For example, if a food contains 20 grams of total carbs and 10 grams of dietary fibre, it has 10 grams of net carbs.

The calculation is slightly different for processed foods, which may contain sugar alcohols. Sugar alcohols are only partially absorbed by the body, and so when calculating net carbs, you can subtract half the amount of sugar alcohols from the total number of carbs.

Erythritol is an exception to this rule. Erythritol is a sugar alcohol that is not digested by the body at all, so you can subtract the total amount of erythritol from the total number of carbs.

For example, a food with 20 grams of total carbs, 10 grams of fibre, and 10 grams of sugar alcohols has 5 grams of net carbs.
