Keto Carb Counting: How Many Grams Are Optimal?

The ketogenic, or keto, diet is a low-carbohydrate, fat-rich eating plan that has been used for centuries to treat specific medical conditions. The diet has gained attention as a potential weight-loss strategy, but how many grams of carbohydrates can one eat and still be in ketosis? Most keto diet guidelines recommend limiting total carbohydrate intake to 15-30 grams, or 5-10% of total calorie intake per day. Eating more than 50 grams of carbohydrates may disrupt ketosis, though this varies from person to person. To calculate net carbs, one must subtract the amount of dietary fibre and half the amount of sugar alcohols from the total number of carbohydrates.

To stay in ketosis, aim for 50 grams of carbs or fewer per day

To stay in ketosis, it is recommended that you consume no more than 50 grams of net carbs per day. This is because ketosis is a metabolic state where your body burns fat for energy instead of carbohydrates, its preferred source of fuel. By limiting your carb intake to 50 grams or fewer per day, you can trigger this metabolic state and start reaping the benefits of ketosis.

Net carbs refer to the amount of carbohydrates that are absorbed into your body. To calculate the net carbs in a food item, you subtract the amount of fibre and half the amount of sugar alcohols from the total number of carbohydrates. This calculation is important because it helps you stay within your daily carb limit while still getting the essential fibre your body needs.

When following a keto diet, it is crucial to monitor your carb intake and choose your food sources wisely. Whole, unprocessed foods are recommended, as they provide essential vitamins and minerals. Meat, fish, cheese, and dark, leafy vegetables are all good options, as they are low in net carbs.

It is worth noting that the number of carbs needed to stay in ketosis may vary slightly between individuals. Additionally, different types of keto diets exist, such as the cyclical ketogenic diet and the targeted ketogenic diet, which allow for more flexibility in carb intake. However, for most people, staying within the 50-gram limit is crucial to maintaining ketosis and maximising the potential benefits of the keto diet.

While the keto diet has been linked to several health benefits, it is not suitable for everyone. It is always recommended to consult with a healthcare professional before making any significant dietary changes, especially if you have any chronic health conditions.

Calculate net carbs by subtracting fibre and sugar alcohols from the total carb content

The ketogenic or "keto" diet is a low-carbohydrate, fat-rich eating plan that has been used to treat specific medical conditions and is also gaining attention as a potential weight-loss strategy. To get into ketosis, which is essential for the keto diet, most people will need to consume fewer than 50 grams of carbohydrates per day. This leaves you with limited carb options, mainly vegetables and small amounts of berries.

To calculate your net carbs, subtract the fibre and sugar alcohols from the total carb content. Net carbs refer to the carbs that are absorbed by your body and can be calculated using the following formula:

> Net Carbs = Total Carbs – Fibre – Sugar Alcohols

For example, if a food product has 13 grams of total carbohydrates, 9 grams of fibre, and 2 grams of sugar alcohols, then it has 2 grams of net carbohydrates.

It's important to note that the Food and Drug Administration (FDA) does not recognise the term "net carbs" and instead recommends using the total carbohydrates listed on nutrition labels. Additionally, sugar alcohols like erythritol and xylitol have a negligible impact on blood sugar, so they can be subtracted entirely from the total carb count. However, other sugar alcohols like maltitol, sorbitol, or isomalt have a higher glycemic index and may affect blood sugar levels, so only half of their amount is usually subtracted from the total carbs.

Calculating net carbs can be beneficial for people with diabetes as it helps them track their intake of dietary fibre and balance their medications with carb intake. It also promotes a healthy intake of dietary fibre, which can increase feelings of fullness and help control blood sugar levels. However, counting net carbs might also increase the number of sugar-free treats in the diet, which may not be carb-free, and can cause confusion due to varying food nutritional labels.

Avoid foods like sugar, sweetened beverages, starchy vegetables, and fat-free dairy

A keto diet is a low-carb, high-fat eating plan that has been used to treat specific medical conditions and is now gaining popularity as a weight-loss strategy. The diet involves limiting your daily carb intake to between 20 and 50 grams, which is significantly less than the amount found in a medium plain bagel. This restriction on carbs puts your body into a state of ketosis, where it burns fat for energy instead of carbs.

To follow a keto diet, you should avoid foods that are high in carbs, such as sugar, sweetened beverages, starchy vegetables, and fat-free dairy. Here's a more detailed breakdown of why these foods should be avoided:

Sugar

Sugar is a simple carbohydrate that is quickly broken down and absorbed by the body, leading to a rapid increase in blood sugar and insulin levels. This can be detrimental to maintaining ketosis, as insulin stimulates the storage of fat and blocks its breakdown. Therefore, it is crucial to avoid added sugars and sugary treats like cakes, cookies, and candies.

Sweetened beverages

Beverages that are sweetened, such as regular soda, fruit juice, and dairy milk, are packed with sugar and carbs. Even 100% fruit juice is not recommended due to its high natural sugar content. Instead, opt for unsweetened tea, water, or nut milks, which are keto-friendly choices.

Starchy vegetables

Starchy vegetables, such as potatoes, corn, and winter squash, are also high in carbs and should be avoided. These vegetables can quickly take you over your daily carb limit and stop your body from staying in ketosis. Other vegetables, like asparagus, celery, tomatoes, spinach, and mushrooms, are much lower in carbs and can be safely included in a keto diet.

Fat-free dairy

While dairy products can be a part of a keto diet, some are higher in carbs and should be limited or avoided. Fat-free dairy products, such as skim milk and low-fat yogurt, tend to be higher in carbs because they retain more lactose (milk sugar). For example, a cup of skim milk contains about 12 grams of carbs. Instead, opt for full-fat dairy or fermented dairy products like cheese, butter, and Greek yogurt, which are lower in carbs and can be enjoyed in moderation.

Focus on high-fat foods like fatty cuts of meat, nuts, and seeds

The keto diet is a low-carb, fat-rich eating plan that has been used to treat specific medical conditions. The diet is distinctive for its exceptionally high-fat content, typically 70% to 80%, with a moderate intake of protein. The keto diet is based on the premise that depriving the body of glucose, which is obtained from eating carbs, will cause the body to produce an alternative fuel called ketones from stored fat.

To achieve ketosis, it is important to consume very low carbs and focus on high-fat foods. Fatty cuts of meat, nuts, and seeds are excellent sources of healthy fats and can help you achieve your keto goals.

Fatty Cuts of Meat

Meat is an important part of the keto diet, but it's important to choose fatty cuts that are high in fat and low in carbs. Here are some examples:

• New York Strip Steak: A 7-ounce portion contains 34 grams of fat, making it perfect for a keto meal.
• Ribeye: An 11-ounce portion contains 54 grams of fat and is both affordable and easily accessible.
• Delmonico Steak: These steaks have 50 grams of fat per 8 ounces and are perfect for grilling at home.
• Skirt Steak: A fattier option with excellent flavor, skirt steak has 30 grams of fat per 9-ounce serving.
• Pork Ribs: Pork ribs are a keto-friendly delicacy with 20% daily value of fat per serving.
• Chicken Thighs: The fattiest cut of chicken, bone-in and skin-on chicken thighs yield a fatty broth that can be used for gravy. A 4-ounce serving contains 17 grams of fat.
• Ground Beef: Versatile and great for burgers, tacos, or meat sauce, ground beef comes in varying lean-to-fat ratios. For keto, look for a higher fat ratio, such as 55:45.

When choosing meat for keto, focus on the fat content per serving. Fatty cuts of meat can be cooked in other fats like lard, avocado oil, butter, or coconut oil, and paired with keto-friendly foods like avocado, eggs, and low-carb vegetables.

Nuts and Seeds

Nuts and seeds are low in net carbs and high in healthy fats, making them a perfect fit for the keto diet. They are also packed with protein, fiber, vitamins, minerals, and antioxidants. Here are some of the best nuts and seeds for keto:

• Pecans: These tree nuts have a great nutrient profile for keto, with only 4 grams of total carbs per ounce. They may also help reduce insulin levels, which is ideal for weight loss.
• Brazil Nuts: Grown in South America, Brazil nuts are an excellent source of selenium, a trace mineral needed for various bodily functions. Just one Brazil nut provides more than 100% of your daily selenium needs. However, due to their high selenium content, it's best to limit intake to one to three nuts per day.
• Macadamia Nuts: Native to Australia, macadamia nuts are very high in fat, making them perfect for keto. They have been linked to improved cholesterol levels in several studies.
• Flax Seeds: Flax seeds are full of fiber and omega-3 fats and have been studied for their potential benefits on blood pressure and heart health. They can be added to baked goods, soups, smoothies, and protein shakes.
• Walnuts: Walnuts are a popular tree nut that may benefit heart health by reducing risk factors such as high LDL cholesterol and blood pressure. They make a great snack or ingredient in keto-friendly desserts.
• Hemp Seeds: Hemp seeds are an excellent source of plant-based protein and healthy fats. They may help reduce blood pressure and protect against Alzheimer's and other neurodegenerative diseases.
• Hazelnuts: With a smooth, buttery texture, hazelnuts are well-suited for desserts. They are an excellent source of vitamin E, which has been linked to a reduced risk of heart disease.
• Peanuts: Technically a legume, peanuts are widely available and a great choice for keto dieters. They are an excellent source of plant-based protein and packed with essential amino acids. Enjoy them as a snack or add them to smoothies, keto desserts, or savory Asian-style sauces.
• Sesame Seeds: Sesame seeds are a popular ingredient used worldwide, often as a topping for baked goods. They are low in carbs and high in fat, making them a good choice for keto. They are also packed with anti-inflammatory antioxidants called lignans.
• Pine Nuts: Pine nuts are versatile and have a unique, earthy flavor. They are low in carbs and high in fat, and they contain pinolenic acid, which may decrease hunger by regulating appetite hormones.
• Sunflower Seeds: Sunflower seeds are a popular, high-fat snack that can be a great addition to your keto diet. They are high in anti-inflammatory antioxidants and have been found to have antidiabetic and anti-inflammatory properties in animal studies.
• Almonds: Almonds and almond butter, milk, or flour are versatile keto staples. They have been linked to a variety of health benefits due to their high protein, healthy fat, fiber, vitamin, and antioxidant content. Enjoy them as a snack or add them to smoothies, keto-friendly baked goods, or milk.

By focusing on high-fat foods like fatty cuts of meat, nuts, and seeds, you can achieve and maintain ketosis while enjoying a variety of delicious and nutritious meals and snacks.

Keto is not suitable for everyone, especially those with type 1 or 2 diabetes

The ketogenic diet, or keto, is a low-carbohydrate, fat-rich eating plan that has been used to treat specific medical conditions. While it may be a good option for some people, it is not suitable for everyone, especially those with type 1 or 2 diabetes.

Keto is a very low-carb diet, with total carbohydrate intake reduced to less than 50 grams per day and as low as 20 grams per day. This means cutting out a wide range of foods, including bread, rice, pasta, most fruits, and starchy vegetables. The diet typically derives 70% to 80% of its calories from fat, with the remaining calories coming from protein (10-20%) and carbohydrates (5-10%).

For people with diabetes, the main issue is managing blood glucose levels. While keto can be effective in lowering blood sugar, it also carries risks, especially for those with diabetes. Here are some reasons why keto may not be suitable for people with type 1 or 2 diabetes:

• Risk of ketoacidosis: Keto diets aim for "ketosis," where the body burns fat for energy instead of carbohydrates. However, if ketones build up too much, it can lead to ketoacidosis, a dangerous condition where the blood becomes too acidic. This is more common in people with type 1 diabetes but can also occur in those with type 2 diabetes if ketones are too high.
• Low blood sugar (hypoglycemia): For people with diabetes, especially those on certain medications or insulin, there is a risk of low blood sugar if carbohydrate intake drops too low. Hypoglycemia can be dangerous and cause symptoms such as weakness, sweating, nightmares, and seizures.
• Nutrient deficiencies: The keto diet restricts many nutrient-dense foods, such as legumes, fruits, and whole grains. This can lead to deficiencies in fiber, vitamins, and minerals. The Mediterranean diet, for example, was found to provide more fiber and several vitamins and minerals than the keto diet in a study.
• Difficulty adhering to the diet: The keto diet is very restrictive, and some people may find it too challenging to follow in the long term. This was reflected in a study where participants found the Mediterranean diet easier to adhere to than the keto diet.
• Increased risk of constipation: The keto diet can be low in fiber, which may result in constipation. This is especially important to consider for people with diabetes who may already experience gastrointestinal issues.
• Not suitable for everyone: Managing diabetes requires an individualized approach, and keto may not be the best choice for everyone. It is essential to consult with a healthcare professional before starting any restrictive diet, especially if you have a medical condition like diabetes.

In summary, while keto may be an effective tool for managing blood sugar and weight loss in some people with type 2 diabetes, it is not a one-size-fits-all solution. The risks and benefits should be carefully weighed, and any dietary changes should be made under the guidance of a healthcare professional to ensure safety and effectiveness.
