Keto Diet: Counting Carb Grams For Weight Loss

The ketogenic, or keto, diet is a low-carbohydrate, high-fat eating plan that has been used for centuries to treat specific medical conditions. The keto diet typically restricts total carbohydrate intake to less than 50 grams a day, with some people aiming for 20 to 50 grams of net carbohydrates per day. This is significantly less than the amount of carbs in the standard Western diet, which is usually between 225 and 325 grams of carbs daily. The keto diet is designed to put the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates.

Keto dieters should eat fewer than 50 grams of carbs per day

The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. To stay in ketosis, keto dieters should eat fewer than 50 grams of carbs per day. This is significantly fewer carbs than the standard Western diet, which can include up to 325 grams of carbs daily.

Staying under 50 grams of carbs per day can be challenging, as it limits dieters to mostly vegetables and small amounts of berries. It also means cutting out many healthy foods such as fruits, whole grains, and starchy vegetables like sweet potatoes and carrots. However, keto dieters can still enjoy a variety of foods such as meat, fish, cheese, eggs, non-starchy vegetables, nuts, and seeds.

It's important to note that the keto diet is not suitable for everyone. It can be harmful to people with type 2 diabetes who are on insulin and those with type 1 diabetes. Additionally, it may be risky for pregnant or nursing women as it could lead to life-threatening complications. Anyone considering starting the keto diet should consult their healthcare provider first to ensure it is safe and appropriate for them.

While the keto diet can be effective for weight loss and fat loss, it may not be easy to stick to due to the restrictive nature of the diet. It is also important to ensure adequate nutrition by regularly assessing your nutritional intake and working with a registered dietitian.

Net carbs are absorbed into the body

Net carbs are the total grams of carbohydrates in a given food minus its grams of dietary fibre and certain sugar alcohols. Net carbs are absorbed into the body and are also referred to as digestible or impact carbs.

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 can't be broken down into individual sugars, while others are only partially broken down and absorbed. These include fibre and sugar alcohols.

Fibre is a unique form of carbohydrate in terms of its digestion and effects on the body. Unlike starch and sugar, naturally occurring fibre isn't absorbed in the small intestine. This is because the links between sugar units can't be broken down by the enzymes in the digestive tract. Therefore, fibre passes directly into the colon. However, its fate after that depends on what type of fibre it is.

There are two broad categories of fibre: insoluble and soluble. About two-thirds of the fibre you eat is insoluble, while the other third is soluble. Insoluble fibre does not dissolve in water. It creates bulkier stools and can help prevent constipation. This type of fibre leaves the colon unchanged, provides no calories, and has no effect on blood sugar or insulin levels.

Sugar alcohols are processed similarly to fibre, with a few important differences. Many sugar alcohols are only partially absorbed in the small intestine, and there is a lot of variation among different types. Researchers report that the small intestine absorbs 2-90% of sugar alcohols. However, some are only briefly absorbed into the bloodstream and then excreted in urine.

To calculate net carbs in whole foods, you subtract the fibre from the total number of carbs. For example, a medium avocado contains 17.1 grams of total carbs, 13.5 grams of which is fibre. So, in this case, the net carbs would be 3.6 grams.

To calculate net carbs in processed foods, you generally subtract half of the carbs from sugar alcohols from the total carbs listed on the nutrition label. Erythritol is an exception. If it's the only sugar alcohol in the ingredients list, its carbs can be completely subtracted from the total carbs.

For optimal results on a keto diet, it is recommended to keep your intake of net carbs below 50 grams per day and focus on high-fat foods.

Ketosis is a metabolic state where the body burns fat instead of carbs

Ketosis is a metabolic state where the body burns fat instead of carbohydrates for energy. The keto diet is designed to put the body into this state of ketosis, and to stay in ketosis, a person needs to consume up to 50 grams of carbohydrates per day. This is a very low-carb diet, with only a moderate intake of protein, and a high intake of fat—typically 70% to 80% of total daily calories.

The keto diet is a significant shift in eating habits, and it can be challenging to maintain. It involves drastically reducing the intake of many foods, including fruits, whole grains, starchy vegetables, legumes, and dairy. The diet focuses on high-fat foods, such as fatty cuts of meat, nuts, seeds, avocados, and plant oils.

To enter and maintain ketosis, the body needs to burn stored fat for fuel, which it will do once it runs out of carbohydrates. This shift in the body's energy source can lead to weight loss and improved health parameters, such as reduced insulin resistance, lower blood pressure, and improved cholesterol levels.

It is important to note that the keto diet may not be suitable for everyone. It can be potentially harmful to individuals with type 2 diabetes who are on insulin and those with type 1 diabetes. Additionally, it may be risky for pregnant, postpartum, or nursing women as it could lead to life-threatening complications.

Before starting the keto diet, it is recommended to consult with a healthcare professional to ensure it is safe and suitable for your individual needs. Staying within the strict carbohydrate limit can be challenging, and it is important to ensure adequate nutrition by including a variety of allowed meats, fish, vegetables, fruits, nuts, and seeds in your diet.

Ketogenic diets are not suitable for everyone

The keto diet is a low-carb, high-fat eating plan that has been used to treat specific medical conditions such as epilepsy and diabetes. It involves depriving the body of glucose, the main source of energy, so that it starts burning fat for fuel instead. This state is called ketosis.

However, there are several reasons why keto diets may not be suitable for everyone. Firstly, they are very restrictive. Carbohydrates are limited to 20-50 grams per day, which means cutting out many foods such as grains, legumes, fruits, starchy vegetables, and even some types of dairy. This can be challenging to maintain and may cause boredom and cravings.

Secondly, keto diets are high in saturated fat, which has been linked to an increased risk of heart disease. They can also lead to nutrient deficiencies, especially if a variety of recommended foods are not included. For example, the diet is low in fibrous foods like grains and legumes, which can cause constipation. It may also overload the kidneys, which have to metabolize large amounts of protein.

Additionally, keto diets can cause side effects such as increased cholesterol levels, liver problems, fuzzy thinking, and mood swings. In rare cases, they have been associated with a dangerous condition called ketoacidosis, where the blood becomes too acidic.

Furthermore, keto diets may not be suitable for everyone due to individual differences in genetic makeup and body composition. The exact ratio of fat, protein, and carbohydrates needed to achieve health benefits will vary from person to person. Therefore, it is important to consult a doctor and a registered dietitian before starting a keto diet to ensure it is safe and tailored to individual needs.

Keto diets are high in fat and moderate in protein

The keto diet is a high-fat, low-carbohydrate eating plan that has been used for centuries to treat specific medical conditions. In the 19th century, it was used to control diabetes, and in 1920, it was introduced as an effective treatment for epilepsy. Today, it is also being tested and used in closely monitored settings for cancer, diabetes, polycystic ovary syndrome, and Alzheimer's disease.

The premise of the keto diet is that by depriving the body of glucose, its main source of energy, an alternative fuel called ketones is produced from stored fat. The brain demands the most glucose and cannot store it, so during fasting or very low carbohydrate intake, the body first pulls stored glucose from the liver and breaks down muscle to release glucose. If this continues for 3-4 days, blood levels of insulin decrease, and the body begins to use fat as its primary fuel, producing ketone bodies and resulting in a state called ketosis.

The standard keto diet involves getting 70-75% of your calories from fat, 20-25% from protein, and 5-10% from carbohydrates. This translates to about 165 grams of fat, 40 grams of carbohydrates, and 75 grams of protein for a 2000-calorie diet. It is important to note that the protein amount is kept moderate because eating too much protein can prevent ketosis, as amino acids in protein can be converted to glucose.

The keto diet typically limits carbohydrates to 20-50 grams per day, and it is recommended to stay under 50 grams of net carbs per day. Net carbs are calculated by subtracting the amount of dietary fiber and half the amount of sugar alcohols from the total carbohydrate amount.

While the keto diet is high in fat, it is important to choose healthy fats such as monounsaturated and omega-3 fats. Avocados and olives, for example, are unique among vegetables in that they are fairly high in healthy fats and are also good sources of fiber and low in net carbs.

In addition to high-fat foods, the keto diet includes moderate amounts of protein from animal sources such as meat, fish, and dairy, as well as plant-based sources such as nuts and seeds. It is important to ensure adequate protein intake, especially for bodybuilders and older people, to help protect muscle mass.

The keto diet also includes low-carbohydrate foods such as non-starchy vegetables (leafy greens, broccoli, asparagus, bell peppers, etc.), berries, and high-fat veggies like avocados and olives.

By following the keto diet and keeping carbohydrate intake low, the body can be kept in a state of ketosis, which has been shown to promote weight loss and improve health parameters such as insulin resistance, high blood pressure, and elevated cholesterol and triglycerides.
