Keto And Calories: Do They Really Care?

The ketogenic diet is a popular, low-carbohydrate, high-fat, and moderate-protein diet. It is often associated with weight loss, but do people on keto need to count calories?

The general consensus is that strict calorie counting on keto is unnecessary. This is because ketosis, which results from eating very few carbohydrates, teaches your body to burn fat at a greater rate. The keto diet also has a satiating effect, leading to decreased hunger. However, this does not mean that calories don't matter at all on keto. If you are not losing weight, it may be helpful to count calories to ensure you are not consuming too much. Calorie counting can also be useful for those who tend to overeat or eat out of boredom.

Additionally, the type of calories you consume is important. Keto diets are effective for weight loss because they promote nutritional ketosis, a metabolic state where the body burns fat for fuel instead of carbohydrates. This is achieved by restricting carbohydrates and increasing the consumption of healthy fats and proteins.

Calorie counting on keto is unnecessary

The Keto Diet

The ketogenic diet is a high-fat, low-carb diet that promotes nutritional ketosis, a metabolic state where the body burns fat for energy instead of carbohydrates. This diet has gained popularity due to its effectiveness in weight loss.

Calories and Weight Loss

The traditional approach to weight loss involves creating a calorie deficit by consuming fewer calories than you burn. However, the keto diet challenges this notion by emphasizing the types of food consumed rather than the number of calories.

Macronutrients and Satiety

On the keto diet, the focus is on limiting carbohydrates and increasing healthy fat intake. This shift in macronutrients has a satiating effect, leading to decreased hunger and a reduced tendency to overeat. Protein and fat are more filling than carbohydrates, so you feel satisfied with less food and naturally consume fewer calories.

Hormonal Regulation

Hormones play a crucial role in regulating appetite, fullness, and fat storage. Keto meals, which are typically high in protein and fat, trigger the release of satiety hormones and suppress hunger hormones, leading to a natural reduction in calorie intake. This hormonal regulation is a key factor in weight loss, as it helps control cravings and prevents overeating.

The Thermic Effect of Food

The thermic effect of food (TEF) refers to the energy required to break down different macronutrients. Protein has a higher thermic effect than carbohydrates, meaning more calories are used to digest it. This contributes to an increased metabolic rate and can promote weight loss without the need for strict calorie counting.

Calorie Counting Considerations

While calorie counting on keto is generally unnecessary, it can be beneficial in certain situations. For example, if you have reached a weight loss plateau or are consuming too much fat, tracking your calorie intake can help identify areas for adjustment. Additionally, for those with a history of disordered eating, calorie counting should be approached with caution, as it may contribute to increased stress and unhealthy behaviours.

In conclusion, the keto diet's unique approach to macronutrient ratios and its impact on satiety and hormonal regulation make strict calorie counting unnecessary for most individuals. By focusing on food quality and listening to your body's hunger cues, you can achieve successful weight loss without the stress of meticulously tracking every calorie.

Keto is satiating, reducing hunger

The ketogenic diet is a high-fat, low-carbohydrate, and moderate-protein diet. It is designed to bring the body into a state of ketosis, where fat is burned for fuel instead of carbohydrates. While calories are important on the keto diet, the focus is more on limiting carbs and increasing fat intake to induce ketosis.

One of the key advantages of the keto diet is its satiating effect, which leads to reduced hunger and increased satisfaction. This is mainly due to the types of foods consumed on the keto diet, which include healthy fats and proteins that are known to be more filling and satisfying than carbohydrates.

The Science Behind Keto's Satiating Effect

The satiating effect of the keto diet is supported by scientific research. Studies have shown that ketogenic diets can suppress appetite and reduce hunger cravings. This is partly due to the increase in satiety hormones, such as leptin, and a decrease in hunger hormones, such as ghrelin. The reduction in hunger hormones is due to the body's increased ability to respond to these signals, known as improved leptin sensitivity.

Additionally, the keto diet's anti-inflammatory properties contribute to reduced hunger. Inflammation can impair leptin signaling in the brain, leading to leptin resistance. However, the anti-inflammatory effects of the keto diet improve leptin sensitivity, allowing the body to respond more effectively to lower levels of leptin.

Practical Tips for Maximizing Satiety on Keto

To maximize the satiating effect of the keto diet, it is important to focus on consuming high-quality, nutrient-dense foods. This includes keto-friendly meats, fatty fish, healthy fats, and non-starchy fruits and vegetables. Prioritizing protein in meals can also increase satiety and help reduce hunger.

In addition to food choices, other factors such as sleep, stress management, and physical activity can impact hunger levels on the keto diet. Ensuring adequate sleep, managing stress, and incorporating movement into your routine can help regulate hunger hormones and reduce cravings.

The keto diet is satiating and can effectively reduce hunger by inducing ketosis, altering hormone levels, and reducing inflammation. By focusing on nutrient-dense foods and addressing lifestyle factors, individuals can maximize the satiating effects of the keto diet and achieve their health and weight loss goals.

Calories from different foods are metabolised differently

Calories are indeed a measure of energy, and by definition, all calories are the same. A calorie is the amount of energy needed to raise the temperature of one gram of water by one degree celsius. However, this is where the equality ends.

Different foods go through different biochemical pathways and are metabolised and digested at different rates. This is known as the thermic effect of food (TEF). It is calculated based on the amount of energy in any given food compared to the energy required to metabolise and digest it.

Protein, for example, has a much higher thermic effect (20-35%) than carbohydrates (5-10%) and fat (0-3%). This is because protein is not digested as efficiently as carbohydrates and fats, so our metabolic rate increases after consumption, and a large part of the calories it contains will be used up in the process of metabolising it.

The thermic effect of food is not the only factor that influences how our bodies process and respond to calories. Our brain, for instance, may be the most important organ for regulating weight loss and regain. Our brains can unconsciously alter feelings of hunger, hormone responses, and metabolic set points in reaction to different foods and degrees of weight loss.

Additionally, the type of food we eat can change how much we eat. Studies have shown that participants ate 500 calories more each day when consuming ultra-processed foods compared to less processed foods.

Furthermore, calories from different foods can affect our satiety ("fullness") hormones differently. Certain foods may trigger the release of leptin, CCK, PYY, GLP-1, and inhibit ghrelin (a "hunger" hormone) more than others.

Therefore, it is clear that calories from different foods are metabolised differently and have varying effects on our bodies and overall health.

Keto is a fat-focused diet

The ketogenic diet, or keto, is a high-fat, low-carbohydrate, and moderate-protein diet. It involves getting 70-80% of your calories from fat, 20-30% from protein, and just 5-10% from carbohydrates.

This diet is fat-focused because it aims to bring the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. This metabolic state is achieved by drastically reducing carbohydrate intake, which lowers insulin levels and triggers the release of body fat to be burned or converted to ketones for energy.

The focus on fat, rather than calorie intake, is what sets keto apart from other diets. Here are some reasons why keto is considered a fat-focused diet:

Ketosis and Fat Burning

The primary goal of keto is to induce ketosis, a metabolic state where the body burns fat for fuel instead of carbohydrates. This is achieved by reducing carbohydrate intake to very low levels, typically a maximum of 20-50 grams per day. This restriction on carbs encourages the body to tap into its fat stores, promoting weight loss.

Satiety and Appetite Suppression

Keto is fat-focused because it emphasizes the satiating effects of fat and protein. Meals high in fat and protein are more satisfying and keep you fuller for longer compared to carbohydrate-rich meals. This means you're less likely to overeat or constantly crave snacks. The feeling of fullness, or satiety, associated with keto is linked to the higher intake of fat and protein.

Metabolic Advantage of Low-Carb Diets

Low-carb diets like keto are believed to have a "metabolic advantage" over high-carb diets. This means they increase the expenditure of energy or calories. For example, the body uses more energy to process protein than carbohydrates, resulting in a higher thermic effect of food (TEF). This means you burn more calories digesting protein-rich foods.

Additionally, keto-adaptation more than doubles the rate of fat burning compared to a high-carb diet. The body becomes more efficient at burning fat for energy, which contributes to weight loss.

Hormonal Changes and Insulin Sensitivity

Keto is fat-focused because it induces hormonal changes that promote fat burning and reduce fat storage. Lowering carbohydrate intake reduces insulin levels, which in turn promotes fat burning. High insulin levels are associated with increased fat storage.

Additionally, keto increases insulin sensitivity, meaning the body can respond more effectively to smaller amounts of insulin. This helps regulate blood sugar and further encourages the body to use fat for energy.

Calorie Counting is Not Necessary

On keto, you don't need to count calories obsessively. This is because the diet naturally reduces your calorie intake by eliminating junk food, preventing blood sugar crashes, and increasing satiety. The focus is on the types of food and the ratio of macronutrients rather than strict calorie restriction.

While calories do matter for weight loss, keto simplifies the process by providing a set of understandable rules that you can follow intuitively. It's a more user-friendly approach to managing your energy balance, making it easier to stick to the diet and achieve your weight loss goals.

Calorie counting may be useful in certain situations

Calorie counting is not a requirement of the keto diet. The diet is more focused on limiting carbs and increasing fat intake to push your body into ketosis, a metabolic state where the body burns fat for fuel instead of carbohydrates. However, there are certain situations where counting calories on keto may be useful.

Firstly, calorie counting can be beneficial when starting the keto diet or if you have reached a weight loss plateau. Tracking your food intake can help you identify which foods work best for you and learn portion control. It can also help you figure out what is not working and make any necessary adjustments. Additionally, if you are not seeing results on the keto diet, calorie counting can help you identify if you are consuming too much fat or too many calories overall.

Secondly, if your goal is to gain weight on the keto diet, calorie counting can help ensure you are consuming enough calories to achieve a caloric surplus. Similarly, if your goal is to lose weight, creating a calorie deficit is crucial. While keto-friendly foods can be high in calories, it is possible to consume too many calories on a ketogenic diet through large portions or frequent snacking. Calorie counting can help create the necessary calorie deficit by providing awareness of your intake and promoting portion control.

Furthermore, calorie counting on keto may be useful if you tend to overeat or eat for emotional reasons. While keto diets can suppress appetite and increase satiety due to their high fat and protein content, some individuals may still struggle with overeating or emotional eating. In such cases, calorie counting can provide a reality check on portion sizes and help bring awareness to your eating habits.

Lastly, individuals with specific fitness or athletic goals may benefit from calorie counting on keto. Athletes and those who engage in regular physical activity have higher caloric and macronutrient requirements to support their performance and recovery. Calorie counting can help ensure that these individuals are consuming enough calories and meeting their macronutrient targets to support their active lifestyles.
