Calories Vs Carbs: The Keto Conundrum

The ketogenic diet is a low-carb, high-fat method of eating. While it is generally agreed that calories do matter on keto, there is some debate as to whether or not it is necessary to count them. Some sources suggest that calorie counting is not required, as the keto diet is more about limiting carbs and increasing fat intake to push your body into ketosis. However, others argue that while it may not be necessary for everyone, counting calories can be a useful tool for weight loss, especially when progress has stalled. Ultimately, the decision to count calories or not comes down to individual preference and goals.

Calories do matter on keto

While the keto diet is often associated with a reduced focus on calorie counting, ultimately, calories do matter on keto. This is because, fundamentally, weight loss occurs when the body is in a calorie deficit, consuming fewer calories than it needs to maintain its weight.

Calorie Deficit

The body requires a certain number of calories, or units of energy, to perform essential functions and maintain its weight. This number of calories is referred to as the basal metabolic rate (BMR) and is influenced by factors such as age, gender, body composition, and genetics. Any calories consumed beyond this basal amount will be stored as fat.

Ketosis and Calories

The keto diet, characterised by its low carbohydrate and high-fat intake, induces a state of ketosis in the body, where it burns fat at a greater rate as its primary fuel source. This shift in fuel sources means the body can tap into its almost unlimited fat stores, reducing the need to eat every few hours as is the case with a high-carb diet.

Calorie Counting on Keto

While strict calorie counting is not necessary on keto due to its satiating effects, it can be a useful tool in certain situations. For example, if an individual plateaus and stops losing weight, counting calories can help identify areas where they are consuming more calories than expected. Additionally, those prone to overeating or with a history of disordered eating may benefit from calorie counting to keep their intake in check.

Factors Affecting Caloric Intake

Several factors influence an individual's caloric intake on the keto diet, including activity level, sleep quality, stress levels, intake of processed foods, and alcohol consumption. Optimising these areas can help manage calories effectively. For instance, increasing physical activity can boost calorie burning, while improving sleep quality can reduce the risk of weight gain associated with insufficient sleep.

Strategies for Calorie Management

To support weight loss goals and prevent weight gain, individuals can employ various strategies, such as cooking more meals at home, eating non-starchy fruits and vegetables, and prioritising protein-rich foods. These approaches can help control calorie intake and promote satiety.

In conclusion, while the keto diet emphasises limiting carbs and increasing healthy fats, calories do matter, and understanding their role can help individuals make informed choices to achieve their weight loss goals.

Counting calories isn't necessary on keto

The keto diet is a low-carb, high-fat diet that pushes your body into a state of ketosis, where it burns fat for energy instead of glucose. This shift in fuel sources means that your body can tap into its almost unlimited fat stores, and you don't have to eat every few hours to keep your energy levels up.

The Role of Calories

Calories are a measure of energy, and the number you consume relative to the number you burn will determine whether you gain or lose weight. However, when it comes to the keto diet, strict calorie counting is not necessary. This is because ketosis teaches your body to burn fat at a greater rate and typically has a satiating effect, reducing hunger and increasing satisfaction.

The Importance of Food Quality

The keto diet prioritises whole, minimally-processed foods that are high in quality fats, protein, and fibre, which can help you feel fuller for longer. Focusing on food quality can help regulate your appetite and make it easier to stick to the diet without the need for calorie counting.

The Impact of Hormones

Hormones play a significant role in influencing appetite, fullness, and fat storage. Research suggests that low-carb and keto meals may trigger satiety hormones and suppress hunger hormones, leading to a natural reduction in calorie intake, especially in overweight individuals or those with insulin resistance.

Calorie Counting Considerations

While calorie counting may not be necessary for everyone on the keto diet, it can be beneficial in certain situations. For example, if you tend to eat too much fat on keto, which can lead to a weight loss plateau, tracking your calorie intake can help you identify areas where you may be consuming more calories than you realise. Additionally, if you often overeat or are not satisfied with your weight loss progress, calorie counting can provide increased awareness and accountability.

Factors Affecting Caloric Intake

It's important to note that the number of calories you consume and burn can vary depending on several factors, including your activity level, sleep quality, stress levels, intake of processed foods, and alcohol consumption. Optimising these areas can play a crucial role in managing your calories and achieving your weight loss goals.

A calorie deficit is still important for weight loss

Calories Count

Calories are a unit of energy that the body uses to perform various tasks, from basic functions like breathing to physical activities like running. The body needs to burn a certain number of calories to sustain involuntary processes, and this is called the basal metabolic rate (BMR). While calories are not the only factor in weight regulation, they do matter. If you take in more calories than your body needs, the excess will be stored as fat. Conversely, if you consume fewer calories than needed, your body will release its fat stores, leading to weight loss.

The Role of Macronutrients

Macronutrients (carbohydrates, protein, and fat) provide varying amounts of calories. Carbohydrates and fat are the body's primary sources of energy, while protein is mostly used for cell repair and muscle maintenance. Protein is less efficient as an energy source because it must first be converted to glucose in the liver.

The Impact of Diet Composition

The type of macronutrients consumed also influences weight regulation. Low-carbohydrate diets tend to result in more weight loss than low-fat diets, even when calorie intake remains the same. This is because protein and fat are more satiating than carbohydrates. For example, a breakfast of eggs and bacon will keep you fuller for longer compared to a bagel with the same number of calories.

Hormonal Regulation

Hormones play a crucial role in appetite, fullness, and fat storage. Low-carb and keto meals may trigger satiety hormones and suppress hunger hormones, leading to a natural reduction in calorie intake, especially in overweight individuals or those with insulin resistance.

Insulin Sensitivity

Insulin is a hormone that influences whether the body stores or burns calories. Higher insulin levels promote the storage of energy as fat, while lower levels allow the body to mobilise fat stores for energy. A low-carbohydrate diet helps keep insulin levels low, enabling the body to tap into stored fat for energy.

The Thermic Effect of Food

The thermic effect of food (TEF) refers to the amount of energy needed to consume and digest different macronutrients. Protein requires more energy to be digested than carbohydrates or fat. The TEF for protein is 25%, meaning 25% of the calories from protein are used for digestion, while for carbohydrates, it's only 8%.

Individual Variation

It's important to note that the impact of calories and macronutrients on weight loss can vary between individuals. Factors such as genetics, insulin sensitivity, muscle mass, and exercise level all play a role in weight loss or gain. Additionally, some people may find they need to count calories to ensure they are in a calorie deficit, while others may achieve the same results by focusing on whole foods and portion control.

Calorie Counting on Keto

While calorie counting is not necessary on the keto diet, it can be beneficial in certain situations. For example, if you have reached a weight loss plateau, counting calories can help identify areas where you may be consuming more calories than expected. Additionally, those with a history of binge eating or disordered eating may find calorie counting helpful to manage their intake and prevent overeating.

In summary, while the keto diet emphasises limiting carbs and increasing fat intake, calories still play an essential role in weight loss. To achieve and maintain a healthy weight, it's crucial to understand the impact of calories and make adjustments as needed, whether that involves calorie counting or focusing on whole foods and portion control.

The thermic effect of food

The energy required to digest each macronutrient (its TEF) can be expressed as a percentage of the energy provided by the macronutrient. Here is a breakdown of the TEF of each macronutrient:

• Fat provides 9 calories per gram, and its TEF is 0-5%.
• Carbohydrates provide 4 calories per gram, and their TEF is 5-15%.
• Protein provides 4 calories per gram, and its TEF is 20-30%.

Protein has the highest thermic effect, followed by carbohydrates, and then fats. This means that the body burns more calories digesting protein than it does for carbohydrates or fats.

It is important to note that the thermic effect of food is just one aspect of a healthy diet and should not be the sole focus of dietary choices. A well-balanced diet that includes a variety of nutrient-rich foods, regular physical activity, and adequate rest are crucial for achieving and maintaining a healthy weight.

Counting calories can be a short-term tool

However, it is important to note that calorie counting is not a sustainable long-term solution. Instead, focusing on eating high-quality, nutrient-dense, whole foods that are high in protein and healthy fats will naturally lead to eating fewer calories and reaching your goals with ease. This is because keto meals tend to be more satiating, reducing hunger and increasing satisfaction, which naturally leads to a reduction in calorie intake.

Additionally, hormonal regulation plays a crucial role in weight loss. Low-carb and keto meals may trigger satiety hormones and suppress hunger hormones, leading to a natural reduction in calorie intake, especially in those who are overweight or have insulin resistance. Therefore, while calories do matter on a keto diet, it is not necessary to count them strictly. Instead, prioritising whole, minimally-processed foods and maintaining a calorie deficit will help achieve weight loss goals.
