Keto Calorie Conundrum: Burn More, Eat Less, Or Both?

The ketogenic diet is a low-carb, high-fat diet that has gained popularity for its weight loss benefits. The diet typically consists of 5-10% carbohydrates, 70-80% healthy fats, and 20-30% protein. While the keto diet can be effective for weight loss, it is not a magic bullet. Calories still matter on keto, and to lose weight, you must burn more calories than you consume.

One of the main benefits of the keto diet is its ability to suppress appetite and increase satiety, making it easier to stick to a calorie deficit. Additionally, keto can boost your metabolism, with people in ketosis burning about 300 extra calories per day. However, this does not mean you are always burning body fat, and a calorie deficit is still necessary for weight loss.

In conclusion, while the keto diet can be a useful tool for weight loss, it is not a guarantee. Calorie intake, exercise, stress levels, sleep quality, and other factors all play a role in weight management, and individual results may vary.

Keto helps burn more calories by suppressing your appetite

The ketogenic diet is a proven way to lose weight. It is a low-carb, high-fat diet that puts your body in a state of ketosis, where it burns fat for energy instead of carbohydrates. This diet has gained popularity due to its weight loss benefits and has also been used to treat other conditions such as type 2 diabetes, metabolic syndrome, and epilepsy.

One of the key mechanisms behind the keto diet's effectiveness is its ability to suppress appetite. Here's how it works:

Blocking Ghrelin, the Hunger Hormone

Keto diets suppress your appetite by blocking ghrelin, the body's main hunger hormone. Research suggests that as you lose weight, your body releases more ghrelin, making you feel hungrier and potentially sabotaging your diet. However, a ketogenic diet suppresses appetite and prevents this weight loss-induced increase in ghrelin, making it easier to stick to a calorie deficit.

Increased Satiety

The keto diet also increases satiety, making you feel fuller for longer. This is partly due to the satiating properties of protein, which is a significant component of the keto diet. Additionally, a diet higher in fat delivers more fatty acids to the small intestine, releasing more cholecystokinin, a hormone that may impact satiety.

Reduced Cravings

The keto diet can also reduce cravings, especially for carbohydrates. Carbohydrates can cause a significant increase in food consumption, so by reducing carb intake, you can better control your appetite.

Improved Blood Sugar Control

Ketosis also improves blood sugar control. High blood sugar levels can lead to increased hunger and cravings. By removing carbs from your diet, keto can drastically lower blood sugar, reducing hunger and promoting weight loss.

Increased Energy Efficiency

The process of converting fat into energy is more energy-efficient than converting glucose. Therefore, those in ketosis may eat less because they use less energy to convert food into fuel.

While the keto diet can be an effective tool for weight loss and appetite suppression, it is important to note that it may not work for everyone. Some people may still experience hunger and cravings, especially at the beginning of their keto journey. Additionally, long-term calorie restriction can contribute to increased stress levels and unhealthy behaviours, so it is essential to listen to your body and make adjustments as needed.

It increases your metabolic rate

The keto diet can increase your metabolic rate in several ways. Firstly, it switches your body's fuel source from glucose to fat, which can boost your metabolism. This is because burning fat requires more energy, and the body has to work harder to utilise fat for fuel. Additionally, keto diets are low in carbohydrates, which means your body has to rely on fat for energy. This shift in fuel source can lead to a more efficient metabolism.

Secondly, the keto diet can increase your metabolic rate by reducing insulin levels. Insulin is a hormone that regulates blood sugar and promotes fat storage. When insulin levels are high, the body is less likely to use fat for energy. By lowering insulin levels, the keto diet can encourage the body to burn more fat, leading to an increase in metabolic rate.

Thirdly, keto diets are often high in protein, which has a high thermic effect. This means that the body uses more energy to digest and absorb protein compared to other macronutrients. As a result, a high-protein keto diet can increase the number of calories burned throughout the day, boosting your metabolic rate.

Finally, keto diets can increase your metabolic rate by reducing hunger and cravings. When you eat fewer carbohydrates, your body produces less insulin, which can lead to reduced hunger and a lower appetite. This can result in a decrease in calorie intake, which can contribute to weight loss and an increase in metabolic rate.

In summary, the keto diet can increase your metabolic rate by switching your body's fuel source to fat, reducing insulin levels, including high amounts of protein, and suppressing hunger and cravings. These factors work together to boost your metabolism and promote weight loss.

It helps burn stored body fat for energy

The ketogenic diet is a low-carb, high-fat diet that can be effective for weight loss. It involves getting most of your calories from fat, some from protein, and very few from carbohydrates. Typically, a keto diet consists of 5-10% carbohydrates, 70-80% healthy fats, and 20-30% protein.

One of the key benefits of the keto diet is its ability to help the body burn stored body fat for energy. When you drastically reduce carbohydrate intake, your body enters a state called ketosis, where it becomes very efficient at burning fat for energy instead of glucose. This is because, in the absence of sufficient carbohydrates, your body breaks down fat or protein for energy. Fat is the preferred choice as it is rich in energy, and the body can usually afford to lose fat without any consequences.

During ketosis, the body turns fat into ketone bodies, which can be used for energy by various organs, including the brain. This process occurs mainly in the liver, which converts fat into ketone bodies and sends them to parts of the body that need energy.

The keto diet is particularly effective for burning stored body fat during exercise. A study by Volek et al. (2008) found that runners adapted to a ketogenic diet burned 2.3 times more fat per minute during a workout compared to runners on a low-fat diet. This increased ability to burn fat can provide various health benefits and protect against obesity in the long term.

While the keto diet can be beneficial for burning stored body fat, it is important to note that it may not be suitable for everyone and can be challenging to maintain. Additionally, it is crucial to prioritize whole and minimally processed foods and ensure adequate nutrient intake, as the keto diet can be restrictive.

It helps reduce harmful belly fat

Belly fat, or abdominal fat, is linked to an increased risk of several health conditions, including metabolic disease, type 2 diabetes, cardiovascular disease, and even a shorter life. It is also associated with a higher risk of severe Covid-19 complications. The good news is that belly fat can be reduced, and a ketogenic diet is a very effective way to do this.

A 2004 study compared the effects of a ketogenic diet and a low-fat diet on weight loss and body composition in overweight men and women. The ketogenic group lost more total weight, body fat, and abdominal trunk fat than the low-fat group. These findings were more apparent in men than in women, likely because men tend to store more fat in this area.

Another study, published in 2019 by researchers from Virta Health, reported a 15% reduction in abdominal fat on the keto diet over two years. Other studies have also shown that a low-carb diet leads to greater loss of abdominal fat than a low-fat diet.

In addition to its effects on weight loss, a ketogenic diet has been shown to have powerful benefits against type 2 diabetes and metabolic syndrome. It can also help treat cancer and has been used to treat epilepsy since the 1920s.

So, if you're looking to reduce harmful belly fat, a ketogenic diet may be a great option. However, it's important to note that genetics also plays a role in where we store fat and how quickly our bodies can adapt after weight loss. Additionally, a sustainable diet that provides adequate nutrition is crucial for long-term success.

It helps burn more fat during exercise

The ketogenic diet can help you burn more fat during exercise. A ketogenic diet improves your metabolic flexibility and helps your body burn stored fat for energy instead of glucose.

A 2017 study of elite competitive walkers showed that athletes on ketogenic diets were able to burn significantly more fat during training compared to walkers on a more standard diet that included carbohydrates. The study also found that the athletes on the keto diet experienced worse athletic performance than those on the standard diet. They complained that they felt it took greater exertion to complete the same workouts as the athletes on the standard diet.

Another study in 20 endurance athletes had similar findings, reporting that following a ketogenic diet for 12 weeks improved performance, body composition, and fat burning during exercise.

One review reported that increased levels of ketone bodies from supplements may speed up muscle recovery and reduce the breakdown of protein following endurance exercise.

However, it's important to note that the ketogenic diet ultimately impaired exercise performance in these athletes. This is because the human body stores carbohydrates in muscle cells as muscle glycogen, which becomes an immediate fuel source for the body during high-intensity exercise. As your body burns fat for energy rather than carbohydrates when on the keto diet, the process is overall less efficient.

Therefore, the keto diet tends to limit performance during high-intensity workouts, while lower-intensity workouts may be less affected.
