Keto Diet: High Calorie, Low Carb, Healthy?

The ketogenic diet, or keto, is a popular eating style that restricts carbohydrates. It is a very low-carb, high-fat diet that has gained popularity in recent years. While low-carb and keto diets overlap in a few key ways, they vary significantly. Keto is a more restrictive diet, requiring 5% to 10% of calories from carbs, 15% to 30% from protein, and at least 70% to 80% from fat. In contrast, a low-carb diet typically recommends 10% to 25% of calories from carbs, 40% to 50% from protein, and 30% to 40% from fats. Keto is generally safe, but there are potential side effects, and it may not be suitable for those who are pregnant, lactating, or have complex health conditions. It is always recommended to consult a healthcare professional before starting any new diet.

Keto is a high-fat, low-carb, moderate-protein diet

The ketogenic diet, or keto, is a popular style of eating that restricts carbohydrates. It is a very low-carb, high-fat diet that has gained popularity in recent years. While it does have some similarities with low-carb diets, it is by no means the same.

On a keto diet, the goal is to reach a state of nutritional ketosis, where your body uses fat as its main fuel source instead of carbohydrates. This is achieved by consuming fewer than 50 grams of carbohydrates per day, keeping protein intake moderate, and increasing fat intake significantly. The keto diet typically recommends getting 5% to 10% of your calories from carbs, 15% to 30% from protein, and at least 70% to 80% from fat.

This is in contrast to a low-carb diet, which typically includes 10% to 25% of calories from carbs, 40% to 50% from protein, and 30% to 40% from fats. The keto diet is more restrictive and may be challenging to follow for long periods, especially since it can be difficult to build muscle due to its low protein intake.

When following a keto diet, it's important to choose the right foods to ensure you're getting enough healthy fats, moderate protein, and limited carbohydrates. Here are some examples of foods that fit within the keto diet:

• Animal proteins: Fish, shellfish, meat, and poultry are all good sources of protein and are usually carb-free.
• Dairy: Cheese, cream, butter, and unsweetened plant-based milk are suitable options.
• Vegetables: Green leafy vegetables, avocados, olives, and other non-starchy vegetables are recommended.
• Nuts and seeds: Almonds, pumpkin seeds, sunflower seeds, and nut butters are healthy fats and provide some protein.
• Healthy oils: Olive oil, coconut oil, and avocado oil are good choices for cooking and baking.
• Beverages: Unsweetened coffee, tea, and sparkling water are drink options that fit within the keto diet.

It's important to note that the keto diet may not be suitable for everyone. It can be challenging to adhere to in the long term due to its restrictive nature. Additionally, it may cause side effects, especially during the initial transition phase. Before starting any new diet, it's recommended to consult with a healthcare professional or registered dietitian to ensure it's safe and appropriate for your individual needs.

The keto diet is more restrictive than a low-carb diet

A low-carb diet restricts dietary carbohydrates, mainly from grains, sugar-sweetened beverages, and bread. Studies suggest that a low-carb diet comprises 10–30% of calories from carbs, although there is no set definition. This usually equates to 50–150 grams of carbohydrates per day for a person consuming 2,000 calories. On a low-carb diet, it is common to increase protein, healthy fats, and vegetable intake to promote fullness.

The keto diet, on the other hand, is a very low-carb, high-fat diet. It restricts carbohydrates to 20–50 grams per day and requires 70% to 80% of daily calories to come from fats. This puts the body in a state of nutritional ketosis, where it burns fat for fuel instead of carbohydrates. Protein intake on a keto diet should be moderate, as excessive protein can prevent ketosis.

The keto diet is more restrictive in terms of carbohydrate and protein intake. It may be challenging to adhere to long-term due to its limitations and potential side effects, such as constipation, "keto flu," and increased cholesterol levels.

The low-carb diet is less extreme and easier to follow than the keto diet. It allows for a wider variety of foods and is more sustainable in the long term.

Both diets can be effective for weight loss and have potential health benefits, but the keto diet's restrictiveness may make it more challenging to maintain.

Keto can be used to treat epilepsy

The ketogenic diet (KD) is a high-fat, low-carbohydrate, and adequate-protein diet that has been used to treat epilepsy since the 1920s. It is considered an effective alternative treatment for epileptic patients, especially those with drug-resistant epilepsy (DRE). The diet induces a state of ketosis, where the body uses fat instead of carbohydrates as its primary fuel source. This is achieved by consuming fewer than 50 grams of carbohydrates per day while increasing fat intake drastically.

The KD has been found to be effective in reducing seizures in both children and adults with epilepsy. Several studies have shown that the KD can lead to a reduction of over 50% in the number of seizures in epileptic patients. Some patients, around 10-15%, have even become seizure-free after following the KD.

The KD is particularly helpful for certain epilepsy conditions, such as infantile spasms, Rett syndrome, tuberous sclerosis complex, Dravet syndrome, Doose syndrome, and GLUT-1 deficiency. It is usually started in a hospital setting, with close medical supervision, and is carefully monitored by a dietitian. The diet is often individually designed and tailored to the patient's needs.

The KD works by inducing a state of ketosis, which has been linked to a reduction in seizure frequency. Ketosis leads to the production of ketone bodies (KB), which are used as fuel by the brain. KB have been found to have anticonvulsant effects and can reduce neuronal hyperexcitability. The KD also increases the levels of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which helps reduce seizures.

The KD has some side effects, including gastrointestinal symptoms such as constipation, diarrhea, and abdominal pain. It can also lead to weight loss and elevated cholesterol levels. Additionally, the restrictive nature of the diet can make it challenging to adhere to for long periods.

In conclusion, the KD is a valuable treatment option for epilepsy, especially for patients with DRE. It has been shown to be effective in reducing seizure frequency and has multiple mechanisms of action that contribute to its antiseizure properties. However, it is important to carefully monitor patients on the KD and provide support to ensure adherence to the diet.

Keto may be difficult to follow long-term

The keto diet is a popular eating style that involves eating mostly fat (60% to 90% of your calories) and very few carbohydrates (20 to 50 grams per day). While it can lead to quick weight loss, it can be challenging to follow long-term due to its restrictive nature and potential negative health impacts.

Firstly, the keto diet is highly restrictive, which can make it challenging to stick to for extended periods. It requires a significant reduction in carbohydrate intake and a high consumption of fat, which can be difficult to maintain over time. The diet also restricts many healthy foods, such as fruits, certain vegetables, whole grains, and legumes, which can make it difficult to get enough fibre and essential nutrients.

Secondly, the keto diet may have negative impacts on athletic performance. Research has shown that athletes who followed a ketogenic diet performed worse on high-intensity cycling and running tasks compared to those on a high-carb diet. The body is in a more acidic state when in ketosis, which may limit its ability to perform at peak levels.

Thirdly, the keto diet can be challenging to maintain due to the potential for weight regain. Many people may transition to a more relaxed form of keto that allows for more carbohydrates or less monitoring. However, this can lead to weight regain, and the type of weight gained back may be mostly fat, which can affect metabolism and make it harder to lose weight in the future.

Additionally, the keto diet may have long-term health risks. Some studies have found that low-carb, high-fat diets may increase the risk of heart disease, stroke, and type 2 diabetes. There are also concerns about the impact of the keto diet on liver and kidney health, as well as potential nutrient deficiencies.

Furthermore, the keto diet can be difficult to follow due to social and convenience factors. The high-fat foods consistent with a ketogenic diet may not be appealing to everyone, and it can be challenging to find packaged or on-the-go options that fit within the keto macros. Meal planning and preparation are essential for staying on track with the keto diet.

In conclusion, while the keto diet may lead to quick weight loss, it can be challenging to follow long-term due to its restrictive nature, potential negative health impacts, and social and convenience factors. It is important to consult with a healthcare professional before starting any restrictive diet to ensure it is safe and suitable for your individual needs.

Keto may help with weight loss

The ketogenic diet is a popular eating style that restricts carbohydrates. It is a very low-carb, high-fat diet that has gained popularity in recent years. The keto diet has several therapeutic properties, such as helping treat epilepsy. It may also impair the growth of certain types of cancer. Furthermore, some people use it to lose weight.

When following a keto diet, the goal is to reach nutritional ketosis. In this state, your body produces ketones from fat in your liver and uses fat as its main fuel source instead of carbohydrates. This is achieved by consuming fewer than 50 grams of carbohydrates per day while keeping protein intake moderate and increasing fat intake.

There is evidence that ketogenic diets can help with weight loss. They may help you lose fat, preserve muscle mass, and improve many markers of disease. Some studies have suggested that a ketogenic diet may be more effective than a low-fat diet for weight loss, even when matching the total calorie intake.

One older study found that people on a ketogenic diet lost 2.2 times more weight than those on a low-calorie, low-fat diet. Triglyceride and HDL (good) cholesterol levels also improved. Another 2007 study compared a low-carb diet to the Diabetes UK's dietary guidelines and found that the low-carb group lost 15.2 pounds, while the low-fat group lost only 4.6 pounds over three months.

However, it's important to note that the keto diet may not be suitable for everyone. It can be challenging to stick to, and there may be a risk of kidney or liver problems. Additionally, it may not be the best option for elite athletes or those wishing to build large amounts of muscle.
