Mastering Keto: Calculating Your Macros For Success

how to figure macros for keto

The ketogenic diet, or keto, is a popular nutrition plan that emphasises low-carbohydrate intake, high-fat consumption, and moderate protein intake. To achieve ketosis, the body's primary source of energy must shift from carbohydrates to fats. This means that individuals following the keto diet typically restrict their daily carbohydrate intake to a minimal level, forcing the body to burn stored fat for fuel. To figure out the right proportions of macronutrients to achieve and maintain ketosis, it is important to calculate your keto macros. This can be done by using a keto macro calculator, which will help you determine your daily calorie needs and the precise amounts of fat, protein, and carbohydrates to meet your health and weight goals.

Understanding macros: proteins, carbs and fats

Macros, or macronutrients, refer to the three main nutrients that provide calories and energy to the body: proteins, carbohydrates, and fats. These are the building blocks of a healthy diet, and they each play a unique role in supporting your health and fitness goals.

Proteins

Protein is essential for building and retaining muscle mass, and it also slows the digestion of other nutrients, preventing blood sugar spikes. It provides the body with essential amino acids that it cannot produce on its own.

Carbohydrates

Carbohydrates are the body's preferred form of energy because they are less dense than fats and easily accessible. They are converted into glucose to fuel the brain and body. Carbohydrates are found in plant-based foods, with some, like leafy greens, also being high in fibre.

Fats

Fats are the densest form of energy, meaning it takes more space to store fat than protein or carbohydrates. Fats can be obtained from various animal and plant sources, including dairy, meat, seafood, chocolate, olives, and oils.

Keto Macros

The ketogenic diet, or keto diet, is a popular nutrition plan that emphasises low carbohydrate intake, high-fat consumption, and moderate protein intake. The keto macro ratio typically looks like this:

  • 5% of calories from carbohydrates
  • 20-30% of calories from protein
  • 70-80% of calories from healthy fats

The keto diet aims to shift the body's primary source of energy from carbohydrates to fats, resulting in a state called ketosis, where the body burns fat for energy instead of carbohydrates.

Calculating Your Keto Macros

To calculate your keto macros, you can use a keto macro calculator, which will determine your daily calorie needs and the precise amounts of fat, protein, and carbohydrates required to meet your health and weight goals. These calculators take into account factors such as your gender, age, height, weight, and activity level.

Alternatively, you can manually calculate your keto macros by first determining your calorie needs based on your fitness goal (weight loss, gain, or maintenance). Then, estimate your carb needs, which is crucial for promoting ketosis. Research suggests a carb intake of less than 20 to 50 grams per day is sufficient for most people.

Next, calculate your protein needs, which support lean body mass and other essential bodily functions. This can be estimated based on your activity level and fitness goal. Finally, your fat needs can be calculated based on your remaining calories.

Benefits of Counting Macros

Counting macros can be beneficial for achieving nutritional ketosis and ensuring your keto meal plan works effectively for your body and goals. It allows you to tailor your diet to your specific needs and goals, whether that is weight loss, weight maintenance, or increased muscle mass.

How to use a keto calculator

A keto calculator is an online tool that helps people on a keto or low-carb diet to determine their daily macronutrient needs. The three macronutrients, or macros, are carbohydrates, proteins, and fats, which provide calories and energy to the body.

To use a keto calculator, you will need to enter some personal details, including your gender, age, height, weight, and activity levels. This information will help the keto calculator tailor your macronutrient targets to your unique needs and body composition.

Once you have entered your data, the keto calculator will generate a comprehensive breakdown of the number of calories, fats, proteins, and carbohydrates you should consume daily to achieve your specific health and weight goals. Some keto calculators will also provide a dynamic graph that estimates your weight loss timeline, adjusting your calories and macros as you progress and your needs change.

It is important to remember that keto calculators provide estimates, and individual diet responses can vary. Therefore, it is recommended to experiment with your diet and find what works best for your body and goals. Additionally, consulting a healthcare professional or registered dietitian before starting any new diet plan is essential to ensure you receive personalized recommendations based on your unique needs and medical history.

How to count macros

Counting macros is a critical part of the keto diet. Macros, or macronutrients, are the energy-supplying nutrients that the body needs in large quantities. On keto, these are fat, protein, and carbohydrates, in that order of prevalence.

The keto diet is a regimented way of eating, and tracking your macros can help you maintain ketosis. This involves eating a high-fat, moderate-protein, and very low-carb diet. The typical macro ratio for keto is 5% of calories from carbs, 25% from protein, and 70% from fat. This specific macro range promotes ketosis, a metabolic state where your body burns fat for energy instead of carbs.

To count your macros, you can use a keto macro calculator. First, determine your calorie needs based on your fitness goal (lose weight, gain weight, or maintain weight). This will be the foundation for building your macro goals.

For carbs, it is recommended to start with 20-25 grams per day, but you can start at 50 grams if that is too challenging. Remember that carbs provide roughly four calories per gram.

For protein, your needs will depend on your activity level and fitness goal. A moderate activity level and weight loss goal would translate to 0.9g/pound of body weight per day.

Finally, calculate your fat needs based on your remaining calories. Each gram of fat contains about nine calories.

You can also calculate your macros as a percentage of your daily calorie needs. Simply divide the calories from each macro by your total daily calories and multiply by 100%.

In addition to using a keto macro calculator, you can also track your macros manually by writing down what you eat and using a food journal or a nutrition app.

While counting macros can help ensure you're adhering to the keto diet, it's important to note that some dietitians don't recommend this practice due to its potential association with disordered eating and orthorexia. Instead, they suggest focusing on the quality of food and eating a varied, nutrient-rich diet.

How to calculate net carbs

To calculate net carbs, you need to determine the total number of carbohydrates in a food item and then subtract the amount of fibre and sugar alcohols. Net carbs are the number of carbohydrates that are absorbed into the bloodstream and provide the body with energy.

Step 1: Determine Total Carbohydrate Content

Read the nutrition label on the food item and identify the total number of carbohydrates, fibre content, and sugar alcohols. The total carbohydrates listed include starches, sugars, fibre, and sugar alcohols.

Step 2: Subtract Fibre and Sugar Alcohols

To calculate net carbs, subtract the fibre content and sugar alcohols from the total number of carbohydrates. The remaining amount is the net carb count.

It is important to note that not all sugar alcohols are treated equally in this calculation. Sugar alcohols like erythritol and xylitol have a negligible impact on blood sugar levels, so they can be subtracted from the total carb count. However, sugar alcohols with a higher glycemic index, such as maltitol, sorbitol, or isomalt, may impact blood sugar levels and should be treated with caution.

Additionally, if you are using a food product from a country outside the US, be aware that the labelling practices may differ. In some countries, like Australia and Europe, the total carbohydrates listed on the nutrition label may already exclude fibre content. Therefore, you would only need to subtract sugar alcohols to get the net carb count.

Calculating net carbs is essential for people following a keto diet because it helps them stay within their daily carbohydrate limit, which is typically between 20 to 50 grams of net carbs per day. By focusing on net carbs, individuals can include more nutritious, fibre-rich fruits and vegetables in their diet while still maintaining ketosis.

How to calculate protein intake

Protein is an essential macronutrient for anyone on a keto diet. It provides the body with amino acids that it cannot produce on its own and helps build and retain muscle mass. It also slows the digestion of other nutrients, preventing blood sugar spikes, and allows the body to utilise glucose as fuel.

When calculating your protein intake, the first step is to determine your calorie needs based on your fitness goal: are you trying to lose weight, gain weight, or maintain your current weight? This will dictate whether you need a calorie deficit or surplus.

Next, you need to consider your activity level and fitness goals. Are you sedentary, moderately active, or very active? This will influence how much protein you need to consume.

For example, if you are sedentary or looking to maintain your weight, a good rule of thumb is to consume 0.6g of protein per pound of body weight per day. If you are moderately active and trying to lose weight, this increases to 0.9g of protein per pound of body weight per day. For those who are very active and looking to gain muscle, aim for 1.1g of protein per pound of body weight per day.

Let's say you weigh 150 pounds and are moderately active and trying to lose weight. You would multiply 150 by 0.9, which equals 135 grams of protein per day. To get this amount in calories, simply multiply by four, as protein provides four calories for every gram. So, in this case, you would need 540 calories from protein each day.

It is worth noting that some sources suggest keeping protein intake low on keto because it can be metabolised into glucose. However, research indicates that higher protein intake may support better appetite control and a lower body fat percentage without negatively impacting ketosis.

Additionally, it is important to remember that everyone's macronutrient breakdown will look different, and you may need to experiment to find the right balance for your body and goals.

Frequently asked questions

Macros, or macronutrients, refer to the three main nutrients that provide calories and energy to the body: carbohydrates, proteins, and fats.

Ketogenic diet macronutrients refer to the amount of protein, carbs, and fat that's needed for your body to enter nutritional ketosis — a natural metabolic state that results from fat breakdown.

The keto diet follows this standard macro ratio: 5% or fewer calories from carbohydrates, 70-80% of calories from healthy fats, and 20-30% of calories from protein.

You can calculate your keto macros by determining your calorie needs based on your fitness goal (lose weight, gain weight, or maintain weight), then building your macro goals accordingly. You can use a keto macro calculator to help you with this.

Macros are important on a ketogenic diet because they enable you to reach your goal when consumed in the right amounts. For example, protein increases satiety and energy expenditure, and fat supplies energy when carbs are low.
