Counting macros is a popular method used by people looking to lose weight or gain muscle mass. It involves tracking the number of calories and types of foods consumed to achieve certain macronutrient and calorie goals. The three macronutrients to keep track of are carbohydrates, fats, and proteins. The ideal ratio of these macros depends on various factors, including dietary preferences, weight loss goals, and health considerations. For example, a person looking to lose weight and control blood sugar may benefit from a meal plan consisting of 35% carbs, 30% fat, and 35% protein. On the other hand, an endurance athlete may require a higher carbohydrate intake, while someone on a ketogenic diet would consume more fat and fewer carbs.
This paragraph introduces the topic of determining the ideal percentage of macros in an 800-calorie diet. It provides an overview of macro counting, highlights the three main macronutrients, and emphasizes the variability of macro ratios based on individual needs and goals.

The importance of personalising your calorie number
Personalising your calorie intake is essential for maintaining a healthy weight and ensuring your body gets the nutrients it needs. While general guidelines suggest that an average person needs between 1600 and 3000 calories per day, this can vary significantly depending on several factors unique to each individual.
Firstly, let's consider basal metabolic rate (BMR) or resting daily energy expenditure (RDEE). These values represent the minimum number of calories needed to sustain vital bodily functions while at rest. Calculating BMR or RDEE takes into account factors such as body weight, height, age, gender, and body composition (lean mass or body fat percentage). For example, men typically require more calories than women, and individuals with a larger body size or more muscle mass will generally burn more calories, even at rest.
Activity levels play a significant role in determining personalised calorie needs. Those who lead a sedentary lifestyle require fewer calories compared to those who engage in regular physical activity. The type and intensity of exercise also matter—more intense and frequent physical activity will generally require a higher calorie intake to fuel the body and support recovery.
Personalising your calorie number also involves considering your health and fitness goals. If you aim to lose, gain, or maintain weight, you will need to adjust your calorie intake accordingly. For weight loss, creating a calorie deficit is essential, typically achieved by consuming fewer calories than you burn through daily activities and exercise. Conversely, for weight gain or muscle building, a calorie surplus is necessary to provide the body with extra energy and raw materials for growth and repair.
Additionally, certain medical conditions or dietary restrictions may influence your ideal calorie intake. For instance, individuals with kidney issues may need to adjust their protein intake, which can impact their overall calorie consumption. Personalising your calorie number allows you to make these necessary adjustments while still meeting your body's nutritional requirements.
In conclusion, personalising your calorie intake is crucial for optimising your health and wellness. By taking into account individual factors such as BMR, activity levels, health goals, and unique dietary needs, you can determine the ideal number of calories to consume each day. This personalised approach ensures your body receives the nourishment it needs to function, perform, and thrive.

How to calculate your macros
The three main macronutrients are fat, protein, and carbohydrates. The first step in calculating your macros is to determine your weight goal. If you want to lose weight, reduce your calorie intake by 15-25%. If you want to gain weight, increase your calories by 5-15%.
The number of calories a person needs to consume on a daily basis is based on several factors, including height, weight, age, and activity level. The Mifflin-St Jeor Equation is a widely adopted formula that calculates BMR (basal metabolic rate) based on physical characteristics such as body weight and height. The Katch-McArdle Formula calculates RDEE (resting daily energy expenditure) and takes lean body mass into account.
Once you have determined your BMR or RDEE, multiply it by an activity factor to estimate your daily caloric needs. This is known as your TDEE (total daily energy expenditure).
Next, determine your macronutrient needs. The typical macronutrient recommendation for proteins ranges from 10-35% of your total calorie intake. Fat intake should be between 20-35% of your total calories, and the remaining calories are allotted for carbohydrates.
Finally, multiply your total daily calories by your percentages, then divide your calorie amounts by their calorie-per-gram number. For example, if you're following an 1800-calorie diet consisting of 40% carbs, 30% protein, and 30% fat, the calculation would be as follows:
- Carbs: 4 calories per gram; 40% of 1800 calories = 720 calories of carbs per day; 720/4 = 180 grams of carbs per day
- Proteins: 4 calories per gram; 30% of 1800 calories = 540 calories of protein per day; 540/4 = 135 grams of protein per day
- Fats: 9 calories per gram; 30% of 1800 calories = 540 calories of fat per day; 540/9 = 60 grams of fat per day
This results in a daily intake of 180g of carbs, 135g of protein, and 60g of fat.
It's important to note that these are general guidelines, and individual needs may vary. Additionally, alcohol is not a macronutrient, but it still contains calories that should be tracked and can be included under your 'carbohydrates' requirements.

Recommended macro percentages
The number of calories a person needs to consume on a daily basis depends on several factors, including height, weight, age, and activity level, as well as whether they want to maintain, lose, or gain weight. The minimum calorie count recommended for adults is 1,800 calories per day for sedentary women and 2,400 calories per day for sedentary men.
The three macronutrients to keep track of are carbohydrates, fats, and proteins. Macronutrient recommendations vary depending on many factors, including dietary preferences, weight loss goals, and health.
The USDA's Dietary Guidelines for Americans recommend consuming 10% to 35% of calories from protein, 45% to 65% from carbohydrates, and 20% to 35% from fat. The guidelines also suggest consuming less than 10% of total calories from saturated fats.
For those following a 2,000-calorie diet, a popular macro ratio is 40% carbohydrates, 30% protein, and 30% fat. This translates to 200 grams of carbohydrates, 150 grams of protein, and 67 grams of fat.
For a 1,200-calorie diet, a popular macro ratio is also 40% carbohydrates, 30% protein, and 30% fat. This plan provides plenty of protein, which is known to aid in weight loss.
It is important to note that there is no one-size-fits-all diet, and individuals should consider their personal needs, food preferences, and health goals when choosing a plan. Consulting a registered dietitian can be helpful in developing a personalized nutrition plan.

How to track your macros
An 800-calorie diet is considered very low and may not be suitable for everyone. The number of calories a person needs to consume daily is based on several factors, including height, weight, age, and activity level, as well as whether they want to maintain, lose, or gain weight.
Macros, or macronutrients, are the chemical compounds that humans consume in large quantities to provide bulk energy. They include carbohydrates, proteins, and fats. Micronutrients, on the other hand, are vitamins and dietary minerals such as Vitamin A, copper, iron, and iodine, which are also essential but are needed in smaller quantities.
Tracking your macros can help you reach your fitness goals and fuel your body appropriately. Here are some ways to do it:
Use a Macro Calculator
Use an online macro calculator to determine your optimal macronutrient and calorie intake. These calculators take into account your body weight and, for more accurate results, your body fat percentage. They can help you determine whether you need a calorie deficit or surplus to lose weight, build muscle, or maintain your weight.
Determine Your Daily Calorie Intake
Calculate how many calories you want to eat each day. This will depend on your fitness goals and your body's requirements. For example, if you want to lose fat, you will need a calorie deficit, while building muscle may require a calorie surplus.
Calculate Your Macros
Once you know your total daily calories, multiply them by the percentages of each macronutrient you want to consume. For example, if you're following an 1800-calorie diet with 40% carbs, 30% protein, and 30% fat, you would calculate the grams of each macronutrient as follows:
- Carbs: 4 calories per gram x 40% of 1800 calories = 720 calories of carbs per day. 720/4 = 180 grams of carbs per day.
- Proteins: 4 calories per gram x 30% of 1800 calories = 540 calories of protein per day. 540/4 = 135 grams of protein per day.
- Fats: 9 calories per gram x 30% of 1800 calories = 540 calories of fat per day. 540/9 = 60 grams of fat per day.
Use a Tracking App
Use a macro-tracking app such as MyFitnessPal, Cronometer, or Macros+ to input your targets and track your intake. These apps allow you to scan consumed foods and drinks, and they provide handy graphs to show your progress.
Plan Your Meals
Planning your meals ahead of time helps you build meals that meet your macro goals instead of choosing reactively when hungry. Many apps allow you to save meals, making tracking repeated meals more efficient.
Weigh and Measure Your Food
Use a kitchen scale to weigh individual ingredients, then divide the total calories and macros by the number of portions. This ensures an accurate breakdown of macros and calories per meal.
Remember, tracking your macros can be beneficial, but it may also lead to restrictive and obsessive behavior. It is important to ensure your diet meets both your macro and micronutrient needs and includes a variety of minimally processed foods.

The benefits of counting macros
An 800-calorie diet is considered very low and may not be suitable or safe for everyone. The number of calories a person needs to consume daily depends on several factors, including height, weight, age, gender, muscle mass, activity level, and genetics. The general recommended daily caloric intake for women is 1600-2400, while men require 2000-3000 calories.
Counting macros is a popular practice that involves breaking down calorie goals into macronutrients: carbohydrates, proteins, and fats. Here are some benefits of counting macros:
- Weight Management: Counting macros can help individuals maintain a moderate weight. By tracking macronutrient intake, people can ensure they are consuming the right ratio of nutrients to support their weight goals. This practice can be especially useful for those who have previously struggled with weight loss plateaus and weight gain.
- Disease Prevention: Some studies suggest that tracking macronutrients may help prevent certain health conditions. For example, there is evidence that adequate protein intake may protect against Alzheimer's disease in middle-aged and older adults. Additionally, high-carb diets have been linked to a reduced risk of death from diabetes and improvements in cardiovascular health.
- Fitness Goal Achievement: Counting macros can help individuals reach their fitness goals. For instance, a 2017 review indicated that high-protein diets help maintain muscle mass during resistance training.
- Healthier Food Choices: Tracking macros encourages people to make healthier food choices. It helps individuals understand where their calories are coming from and how different macronutrients affect their bodies. This awareness can lead to a more balanced and nutritious diet, ensuring adequate intake of essential nutrients.
- Flexibility: Counting macros offers a flexible approach to dieting. It allows individuals to fine-tune their diet based on their unique needs, health conditions, and activity levels. This flexibility can make it easier to stick to a healthy eating plan and make long-term lifestyle changes.
While counting macros has its benefits, it may not be suitable for everyone. It is always recommended to consult with a healthcare professional or registered dietitian before making significant dietary changes, especially for those with a history of disordered eating.
