Carb Confusion: Are 54G Of Carbs Keto-Friendly?

The ketogenic (keto) diet is a popular eating plan that involves limiting carbohydrate intake and replacing those calories with fat. The goal is to reach a metabolic state called ketosis, where the body burns fat for energy instead of carbohydrates. To reach and maintain ketosis, keto dieters must restrict their daily carbohydrate intake to 50 grams or fewer. However, some sources suggest that consuming 20 grams or fewer of net carbs is ideal for achieving and sustaining ketosis. Net carbs are calculated by subtracting the amount of fibre and sugar alcohols from the total number of carbohydrates consumed.

To enter ketosis, aim for under 50g of carbs per day

The keto diet is a popular, effective way to lose weight and improve health. It involves eating a low-carb, high-fat diet that puts your body into a state of ketosis, where it burns fat for energy instead of carbohydrates. To enter and maintain ketosis, it's crucial to keep your carb intake low. As a general rule, aim for under 50 grams of carbs per day. This may vary slightly between individuals, but it's a good guideline to follow.

Understanding Ketosis and the Keto Diet

Ketosis is a metabolic state where your body burns fat for energy instead of carbohydrates. This shift in energy source can lead to weight loss and have potential health benefits, such as improved management of type 2 diabetes. The keto diet is a dietary approach that aims to induce and maintain ketosis by significantly limiting carbohydrate intake and increasing fat intake.

Carb Intake Guidelines for Ketosis

To enter and stay in ketosis, it is recommended to consume no more than 50 grams of carbs per day. This recommendation is based on scientific evidence and is considered the threshold for most people to achieve and maintain ketosis. However, it's important to note that this number may vary slightly between individuals. Some people, especially those who are healthy, active, and insulin-sensitive, may be able to remain in ketosis with a slightly higher carb intake. On the other hand, those who are less active or have higher stress levels may need to be more strict with their carb intake to stay in ketosis.

Tips for Staying Within the Carb Limit

Staying within the recommended carb limit can be challenging, but here are some tips to help you succeed:

• Focus on whole, unprocessed foods: Choose carbs from whole, unprocessed sources, such as vegetables, to ensure you're getting essential vitamins and minerals while staying within your carb limit.
• Calculate net carbs: Consider calculating "net carbs" by subtracting fibre and sugar alcohols from the total carb count. This allows you to include more fibre in your diet while still maintaining a low-carb intake.
• Gradually reduce carbs: If you're new to the keto diet, consider starting with an upper limit of 50 grams per day and gradually reducing your carb intake. This can help you avoid the unpleasant symptoms of the "keto flu," which can occur during the initial days of carb restriction.
• Monitor your ketone levels: Invest in a blood ketone meter or ketone test strips to measure your ketone levels. This will help you determine if you're in ketosis and how your body responds to different carb intakes.
• Consider carb cycling: For experienced keto dieters, carb cycling involves including higher-carb days in your week. This can help with weight loss plateaus, long-term adherence, and improved sports performance. However, it's important to note that carb cycling is not suitable for everyone, especially beginners or those with diabetes.

Foods to Choose and Avoid

When following a keto diet, it's important to make wise food choices to stay within your carb limit. Here are some guidelines:

• Choose low-carb foods: Select foods with the fewest carbs per serving. Above-ground vegetables and non-sweet fruits, such as berries, are generally keto-friendly.
• Avoid high-carb options: Stay away from bread, baked goods, traditional sweeteners, and starchy vegetables like potatoes. These foods are high in carbs and can quickly exceed your daily limit.

Net carbs are absorbed into the body

When you eat a carb-containing food, most of the carbs are broken down into individual sugar units by enzymes produced in your small intestine. Your body can only absorb these individual sugar units. However, some carbs, like fiber and sugar alcohols, cannot be broken down into individual sugars and are therefore not absorbed by the body.

To calculate net carbs in whole foods, you subtract the fiber from the total number of carbs. For processed foods, it's a bit more complicated. Generally, you subtract half of the carbs from sugar alcohols from the total number of carbs listed on the nutrition label. However, some sugar alcohols, like erythritol, can be completely subtracted from the total carbs if it's the only sugar alcohol in the ingredients list.

The concept of net carbs is important for those following a keto or low-carb diet. To stay in ketosis, a person should consume up to 50 grams of carbs per day, although some sources suggest that under 20 grams of net carbs per day is ideal.

By understanding and calculating net carbs, individuals on a keto or low-carb diet can make more informed food choices and ensure they stay within their desired carb intake.

Total carbs include fibre and sugar alcohols

Total carbs refer to all three types of carbohydrates: starch, fibre, and sugar. When purchasing packaged food, the term "total carbohydrate" refers to all three of these types. The body breaks down most carbohydrates into individual sugar units, which it can then absorb. However, some carbs, like fibre and sugar alcohols, cannot be broken down into individual sugars and are only partially absorbed.

Fibre is a type of carb that the body cannot digest, so it does not transform it into glucose to be used for energy. Instead, it passes directly into the colon. There are two types of fibre: insoluble and soluble. Insoluble fibre does not dissolve in water and helps prevent constipation. It leaves the colon unchanged and has no effect on blood sugar or insulin levels. On the other hand, sugar alcohols are only partially absorbed in the small intestine, and the amount absorbed varies depending on the type. Overall, they don't seem to significantly affect blood sugar and insulin levels, but individual responses may vary.

When calculating net carbs, you subtract the amount of fibre and sugar alcohols from the total carbs. This is because fibre and sugar alcohols are not absorbed or metabolised by the body in the same way as other carbs. However, it's important to note that the Food and Drug Administration (FDA) does not recognise the term "net carbs" and recommends using total carbohydrates listed on nutrition labels.

To calculate net carbs in whole foods, simply subtract the fibre content from the total carbs. For processed foods, you can subtract half of the carbs from sugar alcohols from the total carbs listed on the nutrition label. However, for certain sugar alcohols like erythritol, you can subtract all of the carbs from the total.

Keto-friendly foods include meat, fish, and green vegetables

The keto diet is a high-fat, very low-carbohydrate, and moderate-protein diet. The body usually breaks down carbohydrates from food into glucose, which is its main source of energy. However, when you eat fewer carbs, your body starts to use fat as energy instead, turning it into substances called ketones. This is called ketogenesis and usually begins about 3 to 4 days after you start restricting your carb intake.

Green leafy vegetables are extremely low in carbs and rich in vitamins, minerals, and antioxidants. Broccoli, cauliflower, green beans, bell peppers, zucchini, spinach, kale, and collard greens are excellent choices. Avocados and olives, while technically fruits, are also keto-friendly. They are high in fat and low in net carbs, and the antioxidants they contain have anti-inflammatory properties.

It is important to note that the keto diet is restrictive and may be challenging to follow long-term. It may also lead to side effects such as constipation and "keto flu." Additionally, the long-term health consequences of the keto diet are not yet well understood.

A keto diet can help with weight loss

The keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. In the 1920s, it was introduced as a treatment for epilepsy in children. More recently, it has gained attention as a potential weight-loss strategy.

When you drastically limit your carbohydrate consumption and replace it with fat, your body is forced to use fat from food or your stores as energy instead. This process is called 'ketosis'.

Low-carb, high-fat ingredients include:

• Avocados
• Meat
• Fish
• Eggs
• Cheese
• Cream
• Oil
• Butter
• Nuts and seeds

However, not all ingredients need to be high in fat – leafy greens and berries are often included too. You heavily restrict or avoid wheat and other grains, potatoes, corn, pulses, beans, milk, most fruit, and sugar.

Will it help you lose weight?

Research has shown that a ketogenic diet can induce rapid weight loss, partly from water loss but also some fat loss. However, the "weight loss effect becomes similar to other dietary approaches after one year", according to a 2019 review.

Taking in less energy than you burn will lead to weight loss. On average, we get almost 50% of our energy from carbs. "Cutting this by at least half is likely to reduce total calorie intake, even if it's replaced with fats," says dietitian Sophie Medlin.

Nutritionist Emma Thornton says that "the longer-term effects [of keto diets] aren't well understood". Medlin says the health risks depend on the types of food eaten. Eating an unhealthy diet containing lots of saturated fat may increase health risks such as heart disease and stroke.

Who is it good for?

The keto diet might not be for everyone. If you take any medication or have any medical issues, consult a doctor or dietitian before starting. For some people, a keto diet may cause harm, even with careful monitoring.

Alternatives

There are other ways to lose weight, such as checking your portion sizes and increasing your vegetable intake, or cooking from scratch at home and expanding your knowledge of fresh ingredients.
