Keto Diet: Mastering Carb Intake For Weight Loss

The ketogenic, or keto, diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. In recent years, it has gained popularity as a weight-loss strategy. The keto diet involves significantly reducing carbohydrate intake and replacing those calories with fat, putting the body into a state of ketosis. The number of carbs a person can eat and remain in ketosis varies, but generally, it is recommended to consume no more than 50 grams of net carbs per day. Net carbs are calculated by subtracting the amount of dietary fibre and half the amount of sugar alcohols from the total number of carbs. While the keto diet can be effective for weight loss, it is very restrictive and may cause side effects such as lethargy, nausea, and muscle cramping. It is important to consult with a doctor or dietitian before starting the keto diet to ensure it is safe and appropriate for your individual needs and health status.

The keto diet is a low-carb, high-fat eating plan

The keto diet involves drastically reducing your carbohydrate intake and replacing those calories with fat. This puts your body into a metabolic state called ketosis, where it becomes incredibly efficient at burning fat for energy.

The standard keto diet consists of 70% fat, 20% protein, and 10% carbs. To stay in ketosis, a person can consume up to 50 grams of carbs per day. However, if you want to get into ketosis even more quickly, it is recommended to keep your net carb intake to less than 20 grams per day. Net carbs are calculated by subtracting the amount of dietary fiber and half the amount of sugar alcohols from the total number of carbs.

The keto diet is not just about restricting carbs, it is also about increasing your intake of healthy fats. A typical keto diet will include foods such as red meat and poultry, fatty fish, non-starchy vegetables, dark leafy greens, avocado, coconut oil, bone broths, and plenty of water.

It is important to note that the keto diet can be challenging to maintain and may cause side effects such as lethargy, headaches, nausea, and muscle cramping. It is also not suitable for everyone, especially pregnant women, serious endurance athletes, and people managing Type 1 diabetes. If you are considering starting the keto diet, it is important to consult with your doctor first.

To stay in ketosis, aim for up to 50g of carbs per day

To stay in ketosis, it is recommended to consume up to 50 grams of carbohydrates per day. This may vary slightly between individuals, but generally, sticking to this limit will help maintain ketosis. The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. This means that the body's primary source of energy shifts from glucose, derived from carbohydrates, to ketones, derived from stored fat.

To achieve and maintain ketosis, it is crucial to monitor your carbohydrate intake and choose your food sources wisely. Net carbs, which are absorbed into the body, are the most critical factor to consider. Net carbs can be calculated by subtracting the amount of dietary fibre and half the amount of sugar alcohols from the total carbohydrate content. On the keto diet, it is recommended to consume no more than 50 grams of net carbs per day.

It is important to note that not all carbohydrates are created equal. Whole, unprocessed foods like non-starchy vegetables, nuts, and low-fructose fruits are encouraged on the keto diet as they provide essential nutrients and fibre. However, processed and refined carbohydrates like wheat products, sugar, and starchy vegetables should be limited as they can quickly push you over your daily carb limit.

Additionally, it is worth mentioning that the keto diet is not just about restricting carbs. It also involves consuming moderate amounts of protein. Excess protein intake can prevent ketosis, so it's important to find the right balance between protein and fat.

Finally, when starting the keto diet, it is common to experience an adaptation phase that can last up to five weeks. During this time, you may feel lethargic and experience symptoms like headaches, nausea, and muscle cramping as your body adjusts to using fat for fuel. This transition period will pass, and you will start to notice the benefits of the keto diet, including weight loss, increased energy, and improved mental clarity.

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

To successfully follow a keto diet, it is important to understand the difference between total carbs and net carbs. Total carbs refer to all carbohydrates, whereas net carbs are the ones that are absorbed into your body. Net carbs are the more important number to consider when following a keto diet, as they indicate how many carbs you are actually consuming.

To calculate net carbs, you must first determine the total carb content of a food by looking at its nutrition label. This includes the total amount of carbohydrates, fibre, and sugar alcohols. Once you have this information, you can calculate the net carbs by subtracting the amount of dietary fibre and half the amount of sugar alcohols from the total carb content. For example, if a food has 20 grams of total carbs, 8 grams of fibre, and 5 grams of sugar alcohols, the net carb count would be 7 grams (20 grams - 8 grams - 5 grams = 7 grams).

It is important to note that the calculation for net carbs may vary for different types of sugar alcohols. Erythritol, for instance, can be completely subtracted from the total carb amount, as it is not digested or absorbed by the body. On the other hand, other sugar alcohols, such as maltitol, sorbitol, and isomalt, have a higher glycemic index and may impact your blood sugar levels, so only half of their carb content should be subtracted.

By focusing on net carbs rather than total carbs, you can ensure that your body is getting the essential fibre it needs while still maintaining a low-carb diet. This calculation can be easily applied to a variety of foods, including whole foods and processed foods, to help you make informed choices when following a keto diet.

The keto diet can cause lethargy, headaches, nausea, and muscle cramping

The keto diet can lead to some unpleasant side effects, including lethargy, headaches, nausea, and muscle cramping. This is often referred to as the "keto flu". The good news is that these side effects are usually temporary and tend to subside within a few weeks as your body adjusts to the new diet.

The keto diet is a significant shift from the standard diet, which typically includes 50-55% carbohydrates. In contrast, the keto diet drastically reduces carbohydrate intake to around 5%, replacing carbs with healthy fats and moderate protein. This shift can be challenging for the body to adjust to, and the "keto flu" is a common experience for many people starting the keto diet.

Lethargy or fatigue is a common symptom of the "keto flu". This is often caused by a mild sodium deficiency, as the keto diet leads to lower insulin levels, which in turn cause the body to shed excess sodium and water. To combat this, it is important to add more sodium to your diet, either through salting your food or drinking a cup of broth daily.

Headaches can also be a result of the same sodium deficiency, as well as the body's transition from burning carbs to burning fat for energy. Staying well-hydrated and ensuring adequate sodium intake can help alleviate these headaches.

Nausea is another possible side effect of the keto diet and is often part of the "keto flu". This can be due to the overall adjustment your body is going through, as well as the shift in your gut microbiome. Probiotics and digestive enzymes may help ease nausea and other digestive issues during this transition.

Finally, muscle cramping can occur due to electrolyte imbalances caused by the keto diet. In addition to sodium, potassium, magnesium, and calcium are also important electrolytes to focus on. You can get these electrolytes from foods such as avocados, leafy greens, nuts, and seeds, as well as from supplements.

It is important to remember that the keto diet is not suitable for everyone. If you are experiencing persistent or severe side effects, it may be best to consult with your doctor or a registered dietitian to ensure the keto diet is safe and appropriate for you.

Keto is not suitable for pregnant women, serious endurance athletes, or people with type 1 diabetes

Pregnant Women

According to Healthline, the keto diet is not recommended for pregnant women. The keto diet is a high-fat, very low-carb eating plan that restricts fruits and vegetables, which are rich in vitamins, iron, and folate, and are essential for a pregnant woman and her growing baby. The keto diet may also cause nutrient deficiencies, as it may lead to low levels of vitamin D, vitamin E, vitamin B-12, and folic acid, which are vital nutrients for the baby's growth and development.

Serious Endurance Athletes

The ketogenic diet has become popular among endurance athletes as a performance enhancer, but there is limited research on its effectiveness. The diet prescribes a significant reduction in carbohydrate intake, which can lead to reduced energy intake and weight loss, which may negatively impact mental, hormonal, and bone health, as well as recovery time and general exercise performance. Additionally, the diet may increase oxygen consumption, promote fatigue, and negatively impact training for certain athletes.

People with Type 1 Diabetes

The ketogenic diet may be beneficial for people with type 2 diabetes, but its effects on those with type 1 diabetes are less clear. While the diet may lead to weight loss and improved glycemic control, there are safety concerns, including an increased risk of dyslipidemia, diabetic ketoacidosis, and hypoglycemia. Insulin therapy adjustments are usually required, and close monitoring of patients is necessary. More research is needed to determine the effectiveness and safety of the ketogenic diet for people with type 1 diabetes.
