Keto Carb Confusion: 20G Carb Limit Unattainable?

The ketogenic diet is a low-carbohydrate method of eating. To go into ketosis and stay there, it is recommended to eat fewer than 20 grams of net carbs each day. However, some people may find it challenging to stick to this limit, especially when consuming vegetables, which can surprisingly contribute a significant amount of carbs. For example, one cup of blueberries or four large carrots can contain around 20 grams of net carbs. While it is possible to eat a variety of keto-friendly vegetables and stay within the carb limit, it requires careful planning and tracking. Some people may choose to aim for a higher carb limit, such as 30 or 50 grams, which can be easier to achieve while still providing the benefits of the ketogenic diet.

Counting net carbs, not total carbs

When starting a ketogenic diet, it is important to keep your macronutrients, or macros, within a certain range. Macros are the three nutrients the human body needs in the largest quantity: protein, fat, and carbohydrates. On a ketogenic diet, you're getting about 70-80% of your calories from fat, 20-25% from protein, and 5-10% from carbs. This is why there is a large focus on tracking your carbohydrate intake.

The total carbohydrate count on a nutrition label includes additional components that count towards the total carbohydrate number. Usually included on labels are sugar, fiber, and sometimes sugar alcohols. Net carbs are the total carbohydrates minus the fiber and sugar alcohols. Net carbs are all the carbohydrates in food that can be absorbed and used by the body for energy.

To calculate net carbs, you take a food's total carb amount and subtract the fiber and sugar alcohols. For example, if a food has 20 grams of total carbohydrates and 8 grams of fiber, the net carb count would be 12 grams.

When eating a low-carb, high-fat diet, it is generally recommended to avoid all added sugar. Sticking to the net carb count will usually allow you to maintain nutritional ketosis without going over your carb count. However, if you are particularly carb-sensitive or eat a lot of high-fiber foods, you may want to watch your total carb intake if you are unable to maintain ketosis.

Some people may find it challenging to stay below 20 grams of net carbs per day. It is important to note that this number can vary depending on age, weight, gender, and physical activity level. Additionally, different people have different levels of carb tolerance, so it is essential to determine your own tolerance through trial and error.

Ultimately, when following a ketogenic diet, it is crucial to focus on counting net carbs rather than total carbs. This will give you a better idea of how many digestible carbs you are consuming and help you stay within your carbohydrate target.

Vegetables that are keto-friendly

The keto diet is a low-carb, high-fat, moderate-protein nutritional plan that aims to put the body into ketosis. This is a state in which the body burns fat for energy instead of carbohydrates. While on the keto diet, it is important to limit your intake of starchy vegetables like corn, potatoes, and peas, and instead opt for non-starchy, low-carb vegetables. Here are some keto-friendly vegetables that you can include in your diet:

• Arugula: Also known as rocket, arugula has a peppery flavor and is an excellent source of calcium, vitamins A and C, and antioxidants. A 4-cup serving of fresh arugula contains only 3 grams of carbohydrates.
• Asparagus: Asparagus is a good source of protein, fiber, and vitamins A, C, and E. It also contains essential amino acids and has potential health benefits such as improving insomnia, high blood pressure, and stress. A serving of four spears of cooked asparagus contains 2 grams of carbohydrates.
• Bell peppers: Bell peppers are packed with vitamins A, C, and E, as well as antioxidants. They have anti-inflammatory, antidiabetic, and antimicrobial properties and may help regulate the immune system. A medium-sized bell pepper contains 7 grams of carbohydrates.
• Broccoli: Broccoli is an excellent source of nutrients, including vitamins C and K, fiber, and flavonoids. It helps keep you hydrated as it is about 70% water and may have anti-inflammatory properties. A medium stalk of broccoli contains 8 grams of carbohydrates.
• Brussels sprouts: Brussels sprouts are a good source of antioxidants, fiber, vitamin C, and vitamin K. They also contain sinigrin, a plant-based compound with potential anticancer, anti-inflammatory, and antimicrobial properties. One cup of Brussels sprouts contains 8 grams of carbohydrates.
• Cauliflower: Cauliflower is a versatile low-carb vegetable that can be used as a substitute for rice, mashed potatoes, or pizza crust. It is a good source of fiber and vitamin C. One cup of cooked cauliflower contains 4 grams of carbohydrates.
• Kale: Kale is a nutrient-dense vegetable that is a good source of vitamins A, C, K, calcium, and magnesium. It has potential health benefits such as managing eye diseases, protecting the gastrointestinal tract, and reducing inflammation. A cup of kale contains less than 1 gram of carbohydrates.
• Mushrooms: Mushrooms are a good source of protein, fiber, B vitamins, copper, vitamin D, and selenium. They may have antimicrobial, antioxidant, and hypoglycemic effects, as well as potential anti-cancer and immunity-boosting properties. A serving of mushrooms contains 3.26 grams of carbohydrates.
• Spinach: Spinach is a good source of vitamins A, C, K, iron, and magnesium. It also contains fiber and has potential health benefits such as slowing cognitive decline and supporting immunity. A half-cup of boiled spinach provides 64% of the daily recommended intake of vitamin A. A 100-gram serving of spinach has 3.63 grams of carbohydrates.
• Tomatoes: Tomatoes are a rich source of antioxidants, including lycopene, which gives them their red color. They are a healthy addition to any diet and may promote skin, bone, and brain health while lowering the risk of heart disease. One medium tomato contains 5 grams of carbohydrates.
• Celery: Celery is very low in carbohydrates, containing only 2.97 grams per 100-gram serving. It is a water-rich vegetable that also provides calcium and potassium.
• Zucchini: Zucchini is rich in vitamin C and also contains phosphorus and potassium. A 100-gram serving contains only 3.11 grams of carbohydrates, making it an excellent choice for the keto diet.
• Romaine lettuce: Romaine lettuce is a good source of beta-carotene and vitamin K, containing only 4.06 grams of carbohydrates per serving.
• Radishes: Radishes are colorful vegetables that add a nice crunch to salads. They are a good source of vitamin C and contain 3.4 grams of carbohydrates per 100-gram serving.
• Cucumbers: Cucumbers are a good source of vitamin K and contain 3.63 grams of carbohydrates per 100-gram serving. They make a great snack when dipped in a full-fat dip.

In addition to these vegetables, avocados and olives, though technically fruits, are also keto-friendly due to their high-fat and low-net-carb content.

The effect of exceeding 20g of carbs

If you exceed 20g of carbs while on the keto diet, you may experience some negative effects. Firstly, it could slow down your weight loss progress or cause you to retain water weight. Additionally, you may feel bloated, have stomach cramps, or feel tired and lethargic. These effects can vary depending on the individual and how long you have been on the keto diet. For example, if you are just starting the keto diet, you may be more likely to experience a headache, stomach ache, or diarrhea. On the other hand, if you have been on the diet for a while, your body may have more leeway in handling a higher carb intake without kicking you out of ketosis.

It's important to note that the number of carbs that will affect ketosis varies from person to person. Some people can handle up to 30g or even 50g of carbs while still remaining in ketosis. However, exceeding the recommended carb intake may result in a loss of the benefits of the ketogenic diet. The deeper you go into ketosis, the more benefits you may experience.

To stay within the recommended carb range, it's crucial to track your macros and choose your foods wisely. Some foods that are commonly consumed on the keto diet include meat, eggs, vegetables like broccoli and spinach, and healthy fats like avocado and coconut. By being mindful of your carb intake and making adjustments as needed, you can maximize the benefits of the keto diet and avoid any negative effects of exceeding the recommended carb limit.

The importance of consulting a healthcare professional

The ketogenic diet is a low-carbohydrate method of eating that has gained popularity for its potential health benefits, including weight loss and reduced inflammation. While it may be tempting to jump right into this diet, it is important to first consult a healthcare professional. Here are several reasons why:

Individualised Guidance

A keto-friendly doctor can provide personalised recommendations and ongoing support to ensure your success. They can assess your individual health status, medical history, and specific goals to tailor the ketogenic diet to your unique needs. This is especially important if you have any underlying health conditions or are taking any medications, as certain diet plans may be contraindicated. For example, people with kidney disease should avoid high-protein diets, and those with high blood pressure or heart failure should steer clear of high-salt diets.

Health Monitoring

A healthcare professional can monitor your health throughout the diet to ensure that you are not experiencing any adverse effects. For instance, if you accidentally consume too many carbohydrates and kick yourself out of ketosis, you may experience bloating, stomach cramps, tiredness, or a headache. A doctor can help you manage these symptoms and advise on how to get back into ketosis safely.

Dietary Education

By consulting a healthcare professional, you can learn about the intricacies of the ketogenic diet and how to implement it effectively. They can provide guidance on which foods to eat and which to avoid, as well as how to calculate net carbs accurately. This knowledge will empower you to make informed choices and increase your chances of success.

Overall Wellness

A keto-friendly doctor can take a comprehensive approach to your wellness, addressing underlying imbalances and focusing on preventive care to promote long-term health and vitality. They can connect your diet with other aspects of your health, such as hormones, exercise, immune function, and gut health, to ensure you are getting the best results.

Weight Loss Strategy

If weight loss is your goal, a doctor can help you modify the keto diet to align with your specific needs and health history. They can also provide ongoing support and accountability to help you stay on track and make permanent lifestyle changes, rather than temporary fixes.

In conclusion, consulting a healthcare professional before starting the keto diet is crucial for ensuring your safety, effectiveness, and overall wellness. They can provide individualised guidance, health monitoring, dietary education, and support for your weight loss and wellness goals. This tailored approach will increase your chances of success and help you achieve lasting results.

The role of insulin in ketosis

The ketogenic diet is a low-carbohydrate method of eating that involves getting about 75% of your daily calories from fat, 20% from protein, and less than 5% from carbs. By restricting carbs, you're changing the way your body burns energy. Instead of using glucose, your body switches to burning fat for fuel. This puts you into ketosis—when your liver converts fatty acids into molecules called ketones to use as energy.

Insulin is a hormone that you make to metabolize carbs. Insulin gets a bad rap in low-carb circles because it suppresses ketone production. So, if you want to get into ketosis and stay there, you want to minimize insulin as much as possible. The easiest way to do this is by changing what you eat. Insulin is produced in response to different foods, so by changing your diet, you can minimize insulin production. That's the point of a ketogenic diet.

Carbs raise insulin levels because you need insulin to metabolize carbs (use them for energy). The more carbs you eat, the more insulin you need. When you eat something carb-heavy, the glucose (carbohydrate) in that food raises your blood sugar. But having high blood sugar all the time is dangerous. So, when your body senses that you've eaten carbohydrates, your pancreas makes some insulin to take that glucose out of the bloodstream and store it somewhere safe (your fat cells) for later use.

To reduce insulin production, lower your protein intake as well. Most people know that carbs have something to do with insulin, but not a lot of people know that protein can also trigger an insulin spike. For example, in one study, adding whey protein to a mixed meal increased the insulin response to the meal. Other types of dairy protein are also insulinogenic—that's why keto focuses on high-fat, low-protein dairy foods (like butter), not high-protein, low-fat dairy foods (like Greek yogurt). It's all about reducing the insulin spike.

A ketogenic diet minimizes insulin by reducing both protein and carbs. This is how it takes the brakes off ketone production and lets you get into ketosis.
